Export CxF/X-4

Creating CxF/X-4 files with custom options

Exporting a CxF/X-4 file from ColorAnt

The Export CxF/X-4 File menu option allows saving spectral data as a CxF/X-4 compatible file. This feature is new in ColorAnt 4.0.

CxF stands for Color exchange Format. CxF files are used to communicate color in a vendor neutral format. CxF/X-4 is an ISO standard (since 2015) and has been designed to define spot colors by measuring and storing spectral information of ink solids and tints, on substrate and process black. This spectral definition allows color management systems to better proof and reproduce spot colors. CxF/X-4 files can also be loaded as a spot color library in ColorLogic ZePrA Smart Color Server.

Procedure

  1. Open spectral measurement data of a test chart or any other measurement data with spot colors. The file must have device data (DCS data) and CIE spectral data. Lab data is and spot color measurements without any percentage values are acceptable.
  2. Select File/Export CxF/X-4 and specify meta data such as  Substrate Name, Substrate Type, Print Process and Surface Finishing.
    Note: Other applications may take advantage of Metadata
  3. Entered the names, selections and options from the drop down menus click Start name and save the file.

CxF/X-4 relates to spot color characterisation only, the full tone of each primary color except black, tints and overprints of the respective color with black are saved.

In other words if you export a full iT8-4 CMYK test chart it ends up with 102 patches for CMY.

Remove redundant patches: A feature to automatically optimize and remove redundant color patches is available with the Export CxF/X-4 (to save CxF/X-4 compatible measurement values). If the checkbox Remove redundant patches is activated all required color patches will be saved only once in the exported CxF/X-4 file, avoiding duplicates.

Include black gradient in export: Also exports the black gradient. Typically, when exporting CxF/X-4 data from a complete test chart, only 100 % black and overprinting spot colors with 100 % black are included, but not the black gradient. However, including the black gradient can be convenient if you want to use the black information from the CxF/X-4 data in other tools (for example, under Edit Primaries).

Note: The CxF/X-4 specification does not explicitly prohibit saving the black gradient, but the original idea is to specify spot colors, not black. Therefore, activating the checkbox can lead to incompatibilities with programs from other manufacturers.

General Information on measurement conditions

The ISO-Norm 13655:2009 defines the various measuring conditions M0, M1, M2 and M3.

M0: Does not define a specific light source but recommends illuminant A. This illuminant represents domestic lighting with tungsten filament at a colour temperature of approximately 2856 Kelvin. The UV content of the light is not precisely defined. Consequently, according to ISO 13655, M0 is unsuitable if the paper fluoresces or if measurement data must be exchanged between locations.

M1: If the substrate contains optical brighteners, this measuring condition minimizes the fluctuations of the measuring results between different devices. D50 must be used as illuminant, i.e. a daylight simulation with a colour temperature of 5003 Kelvin. The radiation intensities of the wavelengths are precisely defined, even those below 400 nm, since these wavelengths excite fluorescence.

M2, also known as “UV-cut”: Applies only radiation energy above 400 nm wavelength to the sample, either through a filter advanced to the optics of the measuring instrument, or computationally. This ensures that fluorescence has no influence on the measurement results.

M3: A polarizing filter is placed in front of the lens of the measuring instrument to suppress the effects of gloss effects on measurement data. Otherwise, the same requirements apply as for measurement condition M2.

Ambient Light Measuring in Measure Tool

The Measure Mode (in the menu bar) allows to select either the Ambient Light Measurement mode (only for supported devices) or the standard Reflectance Measurement mode.

If an instrument such as X-Rite i1Pro and Konica Minolta FD-7 supports both modes a light bulb button is shown in the user interface next to the instrument chooser. Clicking on this bulb button will switch between the modes. Alternatively users can switch the mode in the file menu Measure Mode.

The Ambient Light Measurement mode allows to measure the spectral radiation of a light source as a single color patch.

To measure follow the instructions for the instrument calibration and preparation. An ambient light head must be placed on the instrument to measure the light source accordingly (see instruments manual). Depending on the instrument you may use the button on the instrument to measure or click the Measure button in Measure Tool.

Once the measuring is finished the Luminance, Temperature (in Kelvin), Spectral and XYZ values are shown. If you wish to transmit the current measurement to ColorAnt click the Transmit button.

Ambient light measurements are called Emission in the CIE Data Sets column in ColorAnt. They can be used in the CIE Conversion tool in ColorAnt or in the Viewing Condition section in CoPrAs printer profiling module.

Instruments with Setup Wizards

All supported instruments with Setup Wizards (e.g. the i1iO, Konica Minolta FD-9 and the Barbieri devices) can automatically import the Scan Options (chart size, Rows per page, Gap Size) from the reference file if available. Since these values no longer have to be entered manually, a major source of error during setup and subsequent measurement is eliminated. However, the Scan Options are ONLY stored in the reference file if it was created with the Export Chart tool of ColorAnt 5 (and higher). If this information is not contained in the reference file, it must – as before – be entered manually.

Measuring multiple charts

Multiple charts can be measured in a single session (without closing/opening the Measure Tool after each measurement). Measured charts are automatically added to the Measurements list. The number in brackets indicates the number of measurements. A previously measured chart can be added to this list by using the Plus button which is only enabled if a complete measurement data set is available. Clicking on Measurements opens the list containing all measurements.

If a device with a wizard (positioning) is used (e.g., the X-Rite i1iO) the next measurement can be started by clicking on the Gears icon to enter the wizard/device settings. Clicking the Transmit button transfers the data directly to ColorAnt’s Data Sets section and the Measure Tool is closed.

Remeasure faulty patches/lines

Existing measurement data with erroneous measurement data can easily be corrected by simply remeasuring the faulty parts (lines or patches) of the chart. Just load a previously measured chart, and it is automatically added to the Measurements list as Imported data.

If a file with multiple measurement conditions is loaded, select the appropriate Measurement Condition from the import dialog. Connect the measurement device and measure the faulty lines or patches. By default the first row/patch is selected, but any row or patch can be selected for remeasuring. If a device supports the chosen measurement condition only in a combined multi measurement mode, the data of the selected condition will be copied into all condition slots.

Once the remeasurements are completed, the measurement data has to be added to the Measurements list using the plus sign. Click on Transmit to transfer the data back to the calling application.

Note: If the Measure Tool is opened by an application that only requests one data set/measurement (such as CoPrA or ZePrA), it will start in Single mode. In this mode it is only possible to measure a single file. Once the measurement is complete, transmit the data and quit or return to the Measure Tool:

Click Back to choose another file or remeasure and correct the data. However, in Single mode only one measured data set is shown in the Measurements window. Measuring multiple charts will always overwrite the last measurement (because only one file can be transferred).

If the data is measured with a device that supports multiple measurement conditions, the calling application will display the Import dialog, so that only one of the data sets can be selected for transfer.

Virtual Devices

ColorAnt’s Measure Tool includes three Virtual Devices, the Virtual Device (manual), Virtual Device (spectral) and the Virtual Device (printer). The Virtual Device (spectral) is used for demonstration purposes. The Virtual Device (manual) allows you to manually enter Lab values for selected patches. For example, this is helpful if the device that measured the values is not connected to the Measure Tool or if an older device is used that only displays the measured values on the device itself.
With the Virtual Device (printer) a typical offset printing behaviour can be simulated for test purposes.

Device Options

Once the device is connected, the Barbieri Setup Wizard of the LFP opens:

Position the head of the device on the upper left corner of the chart, see screenshot.
Use the manual positioning on the right side or the automatic positioning to position the head exactly. Auto positioning can only be used if the chart has the necessary margins and markings.

To use auto positioning, activate the Use auto positioning checkbox and click Next. The complete chart is now measured.
Important: In order to use auto positioning, the chart needs the corresponding margins and markings.

To use manual positioning, position the head exactly above the upper left corner using the arrow keys or by entering the x/y coordinates. The measuring head should then be positioned on the outermost corner of the marked patch.

Manual input options for positioning
The four arrows change the position of the measuring head (left, right, up, down). Raise and lower the head with the double arrow in the center.
Tip: Change the position of the head with the corresponding arrow keys on your keyboard.

Horizontal patch gap: Specify the height of the horizontal patch separator in mm.
Vertical patch gap: Specify the height of the vertical patch separator in mm.

Measure options
Measurement condition: M0.
Aperture: Choose between Default, 2, 6, 8 or manual.
Calibration:

  1. Fast: Calibrated at the beginning of each test chart page.
  2. Accurate: Calibrates every second line.

Measure Mode:

  1. Fast (default)
    Fast measuring mode is the default mode of the Spectro LFP. In this mode the measuring head lies on the target and the
    surface is scanned.
  2. Up-Down
    In up-down mode the measuring head of the instrument moves up
    and down between each measurement. Use this mode for sensitive
    materials to avoid any scratches on the surface of the target.
  3. Contactless
    The contactless mode is similar to the above fast mode with a
    difference that the measuring head does not touch the surface
    of the target. This measuring mode is suitable for sticky and
    sensitive materials.

Note: The fast measure mode Fast (default) always uses the same amount of
light and can therefore measure dark and bright samples equally fast. However, the disadvantage is that dark samples in particular are not recorded with sufficient accuracy. The single contact measure mode Up-Down is advantageous here, because
the required amount of light can be individually adjusted for each color patch. This leads to a better differentiation, especially with dark colors.

Start: Starts the measurement of the chart.

Multipage test charts

Manual positioning

If the test chart has multiple pages, a message appears after measuring a page prompting to place the next page on the table:

  1. Place the next test chart page on the table.
  2. Recalibrate the table and use the manual controls as described above to indicate two corners of the chart. The third corner is calculated automatically.
  3. Click Start to measure the next page.

Important: If the second page was placed EXACTLY where the first page was, you can continue without recalibrating. The previously set coordinates will then be used again.

Automatic positioning
When auto positioning is selected:

The checkbox Use auto positioning is activated automatically.

Click Start to autoposition and measure the next page.

Important: In order to use auto positioning, the chart needs the appropriate margins and markings.

Creating charts with Barbieri gateway and measuring using ColorAnt:

Data Sets and History

Data Sets
Displays relevant information about the measurement data: Number of Patches, DCS (color model: Lab, CMYK, RGB, Multicolor) and measurement type CIE (colorimetric = Lab, spectral = Remission).

History
Shows the tools and corrections applied to the measurement data of each editing step and allows switching between different editing states of a file. By clicking on an entry in the History window (either above or below the current status) an individual processing step can be accessed and checked, for example, in the View window.

Save History Log and Averaging Report
Save History Log is available at the bottom right of the main dialog (Fig 2.3).  It saves all modifications applied to all files in a detailed PDF document. When double-clicking a single entry in the History section, a dialog pops up showing the settings applied to the data at a specific step. The single step can be saved with Save Log.

Averaging Features
The averaging log contains detailed reporting with sample colors (similar to the Report feature) comparing the averaged data and providing process control statistics. Standard deviations (sigma) for Density, dE and dH/dL. This allows users to easily recognize colors with large deviations which would not be obvious by visually confirming values.

View and Compare Data
Advanced viewing options for ColorAnt’s tools are located at the bottom of the main window enabling both the inspection of measurement data (View) and the pre- and post-comparison of measurement data (Compare).

To view measurement data, select the data in the Data Sets area and open the View window. Five different options allow for a quick overview of all color patches in the measurement file: the 2D view shows the reference and the corresponding Lab values for each patch, 3D shows a rotating view of the color space, TVI displays the curves for each channel, Spider Web for a top down view, and Curves for various gradations and various curves of gradations.

Color filters: Using the checkboxes, colors can be selectively displayed in 2D and 3D view. All other color patches are then hidden. This allows you to immediately find selected colors in the test chart layout of the 2D view.

The 3D view displays the color body defined by the color filters. This way, the Full Primaries, Limits, Primaries, Secondaries, White or Black can be viewed separately. With Multicolor data, it is easy to recognize in which areas the additional colors extend the color body compared to CMY or CMYK.

There are some dependencies between the color filters, so selecting a certain color filter may automatically activate another color filter (or even several others). For example, if the Secondaries checkbox is activated, the Primaries and White color filters are also automatically activated. They can be deactivated if only two color combinations (Secondaries) are to be highlighted.

Color channels: By selecting color channels, either all color patches or only the color patches of the selected color channels can be displayed. Color channels can be combined with color filters so that, for example, only the Multicolor Primaries or Secondaries can be displayed. Duplex and triplex colors can be displayed by individual selection of suitable color channels (for example, Cyan + Black shows duplex colors and Cyan + Magenta + Black shows triplex colors).

2D View
Color filters highlight selected colors. View full primaries, limits, selected channels, primaries, secondaries, paper white or black. Individual color patches can be edited or deleted by selecting the patch and right-clicking to open a context menu.

3D View
Turn the color patches into the desired direction by clicking and dragging. By dragging the gamut, the color space is rotated in that direction. Increase or decrease the view by using the right side Zoom slider. Enlarge or minimize the color patches by using the Point Size slider.

TVI
Analyze Tone Value Increase curves (TVI). The tone value curve works in conjunction with the curve view or any other correction which will affect the TVI. Choose either Murray-Davies or ISO 20654 (SCTV) methods.

Spider Web
The Spider Web provides a top view of the color space in an a*-b* diagram. The measured or optimized color patches are arranged in a spider web configuration. Verify changes in the View dialog by moving forward or backward in the History list.

Curves
View the linearity curves from white to all 100% primary colors, (including multicolor data). Visualizes data and assists with analyzing non-smooth gradation curves. Choose from ColorLogic Default, ISO 20654 (SCTV) or Tone Value.

03 USING COLORANT

Automatic Correction

The Auto feature optimizes measurement data by applying the following tools in the specified order:

Redundancies: Clean up redundant color patches

Correction: Correcting faulty measurement values

Smoothing:  50% slider setting with no protection of highlights

Each tool that is applied is displayed in the History section. ColorLogic recommends to create a Report for detailed results and further recommendations on your measurement data.

 Procedure

  1. Load measurement data by drag-and-drop onto the Data Sets area or via File > Open.
  2. Click Auto and then Start. The corrections applied to the data are displayed under History.
  3. Save the optimized measurement data as a new file via File > Save as. Use the optimized measurement data in profiling software such as ColorLogic’s CoPrA to create high quality ICC printer profiles.
Measure

Measurement data is acquired with the Measure Tool and transferred to ColorAnt. Measurement data files are stored in the folder Users/Documents/ColorAnt/MeasurementData. The Data Sets section of the main window displays pertinent information about the measurement data including: number of color patches, color model (Lab, CMYK, RGB, Multicolor), measurement value type (colorimetric = Lab – spectral = Remission).

Sidebar tools will be highlighted when applicable to the measurement data, tools which are not applicable are grayed out. Use the tools by first highlighting the data (multiple files can be selected, e.g., by linking or merging several data sets together) and right click. When multiple data sets are present and no set is selected, corrections are applied to all measurement files.

View and Compare Data

View
The View window provides plenty of features that facilitate the evaluation of measurement data. Filters allow the combining of individual channels. Combinations of 2, 3, 4, 5 or 6 channels, as well as one and two channels in combination with black, can be faded in and out. These filters are available in 2D and 3D view.

The number of displayed color patches is shown on the left, i.e., if one or more filters are selected, the number of affected color patches as well as the total number of patches is shown on the left.

Compare
The Color Comparison window shows measurement data (Fig 3.2) before and after optimization. It can also be used to view the actions taken to optimize the data (e.g., File Name Correction, File Name Smoothing). Filters allow the combination of individual channels which are to be compared. 

The Mark from and Mark to slider displays various levels of DeltaE deviations.

Save or export measurement data
The name of every tool applied to correct or optimize data is appended to the name of the data set (e.g., Data_smoothed_corrected). Save the optimized measurement data with File > Save As. Additional export options allow conversion of spectral data to Lab or Density only. Other Save As options include CGATS compatible TXT file, CGATS XML, Named Color ICC profile, CxF compatible CXF file format, Photoshop ACO, color table, Adobe ASE or as GMG CSC file.

Generate Reports
ColorLogic recommends using the Report tool both on the initial data import and after the measurement data has been optimized.

04 DATA IMPORT & EXPORT

Custom Chart

The Custom Chart tool is designed to create reference files for test chart generation. A custom test chart for profiling requires a reference file containing the device data for the color space.

Note: Creating multicolor charts requires a ColorAnt L license.

Depending on the selection of color space, the Custom Chart dialog provides several options:

Gray, RGB and CMYK: Define the Number of Patches and click OK. Select the desired Color Space from the drop-down menu.

CMYK: Choose the linearization from another measurement data set or from another print run as a starting point. To use the linearization feature, load the appropriate measurement file in ColorAnt before opening the Custom Chart tool and select the file under Color Space.

Multicolor Charts
Modifying settings: Select the desired Color Space. For example, to create a 6 color profiling chart, ColorAnt will display a pre-defined color order, in this example: CMYK+Pantone Red and Green. The Eyedropper function allows reordering the channels. To exchange the 5th channel which is Red with Green (similar to fig 4.1) click on the Red Eyedropper Icon and from the Colors section select Green by clicking on it.

Mode: Select one of the presets based on the purpose of the test chart: Profiling, Flexo Profiling, Profile Updating, Linearization or CxF/X-4 Wedge.

Number of patches: Affects how precisely the device color space will be filled with color patches. Please consider the available space on your output, the required accuracy of the characterization data and the capabilities of your printer. Available choices are Large, Medium and Small test charts and a Custom option which allows entering a specific number of patches (the Custom option is not available for CxF/X-4).

Note: The Custom Chart tool works even with only a few patches. The color space is covered in the best possible way to allow proper profile creation.

Changing or defining the channel names
To change channel names, click the Pencil icon, e.g., click the Green channel and type in the new name.

Define the channel name of each channel, (including or excluding CMYK) enter the name in the text field or click on the Eyedropper icon and select a color from the pop up dialog that matches closest.

Linearization
ColorAnt provides intelligent settings that provide a starting point for typical use cases to create Linearization test charts, Profiling test charts, special profiling test charts for Flexo printing and Profile Updating. The Number of Patches feature chooses the optimal number of patches for specific profiling situations.

Note: This option is useful for difficult print processes that are challenging to profile. ColorAnt uses a very smooth linearization to avoid inconsistencies in the curves.

Once the color space, channel names and the Number of Patches are defined, click OK and calculate the reference file. The reference file will appear in the Data Sets section. Save the file if necessary for other chart generation tools. To create a test chart within ColorAnt, select the reference file and click Export Chart.

Export Chart

Export Chart creates test charts based on device color values (e.g., RGB, CMYK, 7 Color etc.), which can be stored as PDF, TIFF or PSD files.

At the top a Preset covering all settings can be selected and manual presets can be created, saved or deleted. The largest section covers options for Chart Dimensions, Patch Sizes and additional Options. The section on the bottom provides information on the number of files to be created with the chosen Preset, settings and buttons to Cancel or create (Start) the test charts. The tool is optimized to work with most of the instruments supported in the Measure Tool. The Custom Chart tool fills the full chart width with patches minus margins for the numbering. Instruments that do not have width limitation (no ruler required) can benefit from this feature.

Ink Limit takes into account printing processes that can’t handle 400% ink on paper/substrate. Typically each of ColorLogic’s CMYK and multicolor test charts have patches with a maximum of 400% ink. If a 400% ink limit is too high for the press, or the user would like to define another ink limit, the user can enter the desired Ink Limit. The resulting chart will have ink limit integrated. Use the exported reference file for measuring and profiling.

Procedure

Step one: Select the reference file with the required device color values.

Step two: Use either one of the presets, or define a custom size and patch width.

Step three: Define the number of patches to be produced.

Measure

ColorAnt’s Measure Tool is used to measure test charts for profile creation.

Measuring test charts

  1. Select Measure from the sidebar.
  2. Select the measurement device under Selection and the measuring mode (M0, M1, M2 or M3).
  3. Connect your device and open the test chart. Charts can be opened via the File menu via the Recently used files and Predefined Charts entries. Your own charts can be added to the list by placing them in the ColorAnt Wedges folder (User\Documents\ColorAnt\Wedges). Alternatively, simply load a reference file or drag-and-drop it onto the window.
  4. Select the Direction of scanning: Patches – Line by line, Patches – Column by column, Scan Rows or Scan Columns.
  5. Begin measuring: Follow the instructions of your measurement device. For the virtual device, double click the first patch to start the measurement.
  6. Transmit Data: When measuring is completed, click the Transmit icon to transfer the data into ColorAnt’s Data Sets section.
Report

A Report offers detailed information for measurement data analysis and provides recommendations for measurement data corrections. It can be used to verify and graphically display the data, and is therefore a powerful feature to document which types of corrections are necessary for the measurement data.

The various report pages provide an insight into the Tonal Value Increase Curves, the gamut representation (Spider Web) as well as the results of the test on the matching of redundant color patches (Quality Evaluation section), measurement or printing errors and the smoothness of the measurement file.

Embed CxF/X-4

Allows to embed spectral measurement data of spot colors (compliant with CxF/X-4) in a PDF file so that other CxF/X-4 compatible tools (e.g., ZePrA) are able to extract or use this data.

Procedure

Open the PDF/X file. The tool lists all spot colors of the PDF file, checks for spot color names that fit those of the CxF/X-4 measurement data and warns in case of conflicts. The data will only be embedded if the spot color names of the PDF file fit those of the CxF/X-4 file (Fig 4.5). When the spot colors match up, click on Start.

05 EDITING

Editing

Redundancies
Corrects color patches by averaging the redundant patches and replacing with the same value.

Correction
Detects faulty measurements or inconsistent measured values and replaces the data with expected measurement values. Use the Protect Lights feature to exempt Flexo data bumps. 

Smoothing
Corrects inhomogeneous measurement data and non-smooth curves by interpolating existing smoothed data. The Auto correction uses the maximum slider setting. Use the Protect Lights feature to exempt Flexo data bumps for being unintentionally smoothed.

White/Black Correction
Apply manual corrections to the most white and darkest color patches, typically the paper or other substrates. The White/Black Correction tool is designed to be used only on a single measurement file.

Brightener
Step one: Analysis
Brightener corrects and analyzes the remission curve of the paper white to determine whether the paper contains optical brighteners or is merely a blue-colored paper.
Step two: Correction
Correction will be applied when optical brightener has been detected. The correction can be adjusted via a slider control and at 100% setting, a similar result will be achieved as if the paper were measured with a UV cut filter.

Tone Value
Corrects measurement data to a specific set of curves. Data is corrected according to specific conditions (e.g., G7, ISO 20654 SCTV). The Protect Lights slider can be adjusted to protect the highlights of flexo data. Correction curves can be exported as Photoshop gradation curves (ACV) and as XML according to ISO 18620 to be used in either Adobe Photoshop or any external RIP software that supports the ISO 18620 standard.

Three options are available:

Correction according to a given profile:
Specify a profile and the measured values are adjusted to achieve the same tone value increase curves as those of the selected profile.

Correction according to:
Tone value curves are calculated to match the requirements of G7 Gray Balance, ISO 20654 (SCTV), G7 + ISO 20654 (SCTV) or ISO 20654 (MultiColor).

Correction according to TVI targets:
Manual editing of each channel (Fig 5.1) allows predefining the increases in tone value to be incorporated in the measurement data

Rescale
ColorAnt can calculate a large test chart based on several measurement files from small test charts. In some printing processes, (e.g., flexo printing on uneven materials) it can be challenging to achieve artifact-free printing of a large test chart. An effective approach to measuring large charts is to place several small test strips on a single page, measure, average and scale up the test strips to a large ECI2002 test chart using the Rescale tool.

 Averaging
Average several measurement files (e.g., press runs) of the same test chart and combine them to form a data set.

 Link
Combine multiple data sets into a single large data set. We recommend to verify the obtained data using the View tool and to optimize the data with either the Auto function or the Redundancies tool.

ICC Transformation
Use both ICC device and DeviceLink profiles on reference data (device data such as CMYK or RGB) to test the impact of an ICC color conversion with up to three profiles.

CIE Conversion
Convert spectral measurement data into another viewing condition. The spectral data are converted to Lab during CIE conversion with the set illumination and the selected observer.

Edit Primaries
Add, remove, and exchange primaries or the paper/substrate in existing measurement data (Fig 5.2).

In typical print production, adding or swapping ink(s) requires the expense of printing a complete, full size test chart. The Edit Primaries tool simply requires the spectral data of the new ink(s) to be added or exchanged. It also recalculates all overprints based on intelligent spectral color models. One of the major features is its ability to dynamically choose the best patches from the data provided. The more complete the provided data, the more accurate the results. This improves the exchange of gradations of the primary color and overprint information, e.g., the primary combined with black. If the selected data contains overprints, such as secondary colors, the Adapt Secondaries feature will take the additional data into account. 

Scenarios for potential efficiency gain with the Edit Primaries tool in production:

Modify channel names: Reorder channel names without modifying data

Variance in press condition: The characterization press run is slightly deficient in solid ink density or hue on one or more colors.

Exchange of paper/substrate: The inks are the same but a slightly different paper shall be used.

Exchanging inks in a print packaging production environment: Create a new profile that swaps colors, e.g., Blue for Cyan or Rhodamine Red for Magenta.

Adjusting the print sequence: Allows improved overprint calculations.

Flexibility for the packaging manufacturer: Create different color variants from a full size 7 color press characterization data set by deleting channels to building new characterization data sets without printing a new test chart. For example, from an original 7C data set (e.g., CMYK+Orange+Green+Violet) build variants for CMYK only, CMY+Violet, CMYK+Orange+Green or other combinations. The production facility would need to ensure the press is stable, and depending on the color needs of the job(s), print select the profile with the least amount of channels.

Increasing CMYK gamut: Adding a 5th, 6th or 7th color to the CMYK printing process.

Using Edit Primaries
We suggest loading another data set with the measured new primaries, gradations of the primaries and overprint information. Select the measurement data of a test chart measurement file for editing and click Edit Primary.

Exchanging a primary: Click on the Eyedropper icon of the color to be exchanged. Select the new primary from another data set loaded in ColorAnt. Click on the channel to be imported to the primary. Fig 5.2 shows a new Cyan ink that is slightly different. Selecting ink from other channels is also possible. Click OK and the data set will be modified.

Important: Using Lab values will not produce the highest quality results. ColorLogic recommends using spectral data. When a data set is present, enter a new Lab value for the selected color or select another channel from the same measurement data set to change the printing order.

Verify the exchange of primaries with the Compare tool.

Exchange paper/substrate
Load the test chart measurement data and load the secondary file containing information of the measured paper white into ColorAnt.

Select the measurement data of a test chart for editing and click Edit Primaries.

Click on the Eyedropper icon of the Substrate/Paper white and select the new paper white from another data set loaded in ColorAnt (Fig 5.3). Click on the name of the data set to import the data. The second option is to manually enter the new Lab values in the text field.

Click OK and the data set will be modified. For large differences in substrates, use the White/Black correction tool.

 Adding channels

  1. Load the test chart measurement data and load the secondary information with the measured primaries, gradation and overprint information into ColorAnt.
  2. Select the measurement data you would like to edit and click Edit Primaries.
  3. Click on Add Channel. A new channel with default gray Lab values and the channel name Auto is added.
  4. Click on the Eyedropper icon of the new channel and select the new primary from another data set loaded in ColorAnt. Click on the channel to import the data. Fig 5.4 shows an example where a 5th Orange color has been added to an original CMYK data set. To rename the channel click on the Pencil icon and enter the new channel name. The new channel can be linearized according to the ISO 20654 (SCTV) standard by selecting the checkbox.
  5. Click OK to generate the new data set. To view the new data set, use the View tool and select the tabs 2D, 3D, Spider Web and TVI to verify all colors including overprints have been added. Additional edits can be made to the curves using the Tone Value tool.

Removing channels
Load the measurement data of a test chart and click Edit Primary. Disable the check boxes in front of the channels that need to be deleted and click OK.The new data set will be reduced to the selected channels.

Color Editor
Edit color patches and process color conversions of spot colors. 

Procedure
The Color Editor allows the user to edit patch names (Fig 5.5), Lab values or device color values (DCS).

Convert and optimize a complete spot color library to a target profile for RGB, CMYK or Multicolor.

To convert spot colors to a desired target profile, first load the spot colors into the ColorAnt Data Sets section, e.g., a Pantone spot color library (or any supported file format such as CxF), then click on Color Editor.

The window contains a table on the left showing all spot colors of the file and editing options on the right.

Select an ICC Profile from the drop-down list and a calculation Mode.

Six modes are available:

  1. Precise Match – Proofing
  2. Visual Match – Utilize More Channels
  3. Use the Least Amount of Channels
  4. Use one Output Channel only
  5. Use a Maximum of two Channels
  6. Use a Maximum of three Channels

The preset dE Limit highlights colors that exceed the defined threshold.

If a color is selected from the table, the device color values for each channel of the selected profile are shown under Optimize Destination Values.

As a default, the device values calculated via the ICC profile are shown without any optimization. By clicking on dE76 or dE00 the deltaE can be minimized (Fig 5.6) for each color.

Clicking on Automatic applies the selected calculation Mode which typically results in a reduced amount of channels for better printability.

Users can optimize each individual color and can even enter device values manually. By clicking on Start, the entire list of colors is generated in the Data Sets section including the calculated and possibly optimized device color values.

The values can be saved for further usage in other applications in any format supported by ColorAnt (CGATS TXT and XML, CXF3, Photoshop ASE and ACO, named color ICC profile or GMG CSC).

FAQ


Does the license file have to be saved on the USB dongle for USB dongle-based licenses?
No, the license file does not have to be saved on the USB dongle. However, it is recommended if the application is to be used on several computers, as the required license file is then always available.

Why does my software not work anymore?
Please make sure that the USB dongle is plugged in and that the serial number of the license file matches the serial number under Registration.

What is the correct order to start the application with USB dongle based licenses?
First plug the USB dongle into your computer, then start the software and load the license under Registration.

What if the application with a computer-based license is to be used on another computer (e.g. if the old computer is broken)?
In this case, please contact the dealer from whom you purchased the software. He will provide you with a document (License Transfer Agreement) for you to sign, in which you agree to delete the old license file and not to use the software on the old computer anymore. You will then receive a new license file for the new computer.

Important: If a computer-based license is to be used, the application must be installed on exactly the computer on which you want to work permanently. You should also make sure that no USB sticks etc. are present before you start the software and open the Registration dialog.

Tip: If you send the serial number to the dealer, it is best to copy and paste the serial number from the Registration dialog (this is easier than writing it down or sending a screenshot). The permanent license file runs only and exclusively on this computer. If you have a computer-based license, you cannot use the software on another computer.

ColorAnt | Preferences

Preferences

Define basic settings

Preferences

Use the ColorAnt Preferences to define the general behavior of the application.

Display Density: Defines the method for calculating and displaying densities in View and Report. There are four options available:

  • Status-E (mainly used in Europe)
  • Status-T (mainly in the US)
  • Status-A (photographic industry)
  • Maximum (based on absorption maximum).

Tone Value Calculation: Changes the calculation and display of the TVI curves in the View dialog.

The default setting in ColorAnt will calculate the TVI curves based on XYZ values. This mode ensures consistent views of TVI curves between measurement data and the same curves derived from ICC profiles. ICC profiles use colorimetric data. When spectral measurement data is present and the checkbox is disabled in Preferences, the TVI curves are based on density and the selected density mode is used for the calculation of the curves. This method is more consistent to the one used in print process control. Keep in mind that both the XYZ and the density method are not good indications for how TVI curves of spot colors actually look as these methods do not work well for non CMYK colors. Refer to the Curves View dialog instead to see curves according to colorimetric linearity or ISO 20654 (also known as SCTV).

Report Settings: Defines the Title and Logo for the generated reports. Supported image formats are TIFF, JPEG or GIF in RGB color space.

General Settings:

Units: Defines the measurement units used (mm or inches) in the Export Chart dialog.

Default Color Space: Defines the color space for the 2D and 3D view of the View tool. Available color spaces are Lab, LCh, YXZ and Yxy.

Main Window: Sidebar – Data Sets – History

Overview

ColorAnt’s main window is divided into 3 sections: The Sidebar, Data Sets and History.

All tools are located and grouped by function on the left side in the Sidebar, measurement data is shown in the Data Sets section on the right hand side upper window.

Tools applied to the measurement data show are shown in the lower right hand side History window.

All ICC profile drop-down menus function as search fields. Simply type in some letters of the desired profile name and only those profiles containing these letters will be shown in the drop-down menu.

Working With ColorAnt

Data Sets

Displays relevant information about the measurement data: Number of Patches, DCS (color model: Lab, CMYK, RGB, Multicolor) and measurement type CIE (colorimetric = Lab, spectral = Remission).

Open or import data

Measurement data can either be opened (File > Open) or dragged and dropped into the Data Sets window.

Note: If measurement data has been saved in an ICC profile (e.g. in profiles created by ColorLogic’s CoPrA), it can simply be dragged and dropped onto the Data Sets window. The measured values are then displayed. If the profile does not contain any measured values, an error message appears (Missing ICC Tag: Could not read color data from file).

Extraction of original measurement data from an ICC profile: This functionality imports the original measurement data from ICC profiles. If you created or updated a profile with CoPrA using the Measurement Processing options Brightener Compensation and/or Measurement Correction, CoPrA stores two data sets inside the profile. The original measurement data (raw data) as well as the corrected data used for profiling (profiling data). ColorAnt extracts both data sets naming them accordingly when opened or when an ICC profile is dragged to the ColorAnt window.

Predefined data and recently opened files are also available from the File menu.

Measurement data can also be captured using the Measure Tool and transferred to ColorAnt. Measurement files created by Measure Tool are saved in the folder User Name/Documents/ColorAnt/MeasurementData.

The ICC specification allows ICC profiles with up to 15 channels. Consequently, ColorAnt allows to load and save test chart measurement data with up to 15 channels. If data with more than 15 channels is to be loaded, a warning is displayed as such data cannot be processed.


Note: This does not affect spot color data. It is still possible to load spot color measurement data containing thousands of colors.

Supported file formats

The following file formats can be opened:
CGATS-Textdatei (TXT) (including multiple tables)
CGATS XML-Datei (XML) (including multiple tables)
Named ICC Profile (ICC)
Color Exchange Format (CxF3)
Photoshop Palette (ACO)
Adobe Swatch Exchange (ASE)

History

History: Shows the tools and corrections applied to the measurement data of each editing step and allows to switch between different editing states of a file. By clicking on an entry in the History window (either above or below the current status) an individual processing step can be accessed and checked, for example in the View window.

Double-clicking on an entry in the History opens a window that displays the settings that were applied to the data in exactly this step. This information can be saved as a PDF document using Save Log.

This has an additional advantage when averaging files using the Averaging tool. The averaging log contains a detailed report with sample colors that compares the averaged data with all files and provides useful statistics for process control, such as standard deviations (sigma, 2 sigma, 3 sigma) for Density, dE and dH/dL. This makes it easy to identify colors with large deviations.

Save History Log: Saves all changes applied to all files to a PDF document.

View and Compare

Advanced viewing options for ColorAnt’s tools located at the bottom of the main window that can be enabled for both viewing measurement data (View) and pre and post comparison of measurement data (Compare). At the bottom of the sidebar, you can access the Registration page, where you can load and manage your licenses. Absolute or Relative Density can be set in ColorAnt’s Preferences.

Contextual Menu

The context menu can be opened with a right click on a selected measurement file or the Gear icon and thus enables quick access to all tools of the Sidebar and the functions from the File menu of the menu bar.

In addition to functions for rotating and mirroring test charts, the context menu also contains the following entries:

Layout: Allows to change the width and height of color patches. For example, you can define the number of rows in a chart by Height and the number of columns by Width.

Intersection: Compare measurement data containing a differing number of color patches and/or color channels. To use this function, choose the two measurement data sets in the main window and select Intersection from the context menu. Alternatively, click the button with the gear symbol to the right below the measurement data list.

ColorAnt then scans both files for color patches with identical device values and removes all other values. This creates two new files containing identical device values which can be compared in the Compare window.

Unlink PCS and DCS: Separates the measurement data from reference data. (Splits files with reference and measurement data into two individual files).

Filter Primaries: Extracts the primary colors from a measurement file.

Filter Full Tones: Extracts the full tones from a measurement file.

Filter Corners: Extracts the corner points from a measurement file.

Filter CxF/X-4 Data: Extracts all values corresponding to the CxF/X-4 specification (e.g., the gradients of the primaries on white and black) from a measurement file.

Filter CxF/X-4 Data With Black Gradient: Extracts all values useful for CxF/X-4 including a black gradient from a measurement file.

 

Patches from Image: Creates an image-related test chart based on a loaded image by extracting the most common/important colors from that image. It can be accessed via the context menu or by dragging and dropping TIFF or JPEG files into ColorAnt’s main window. In the Patches from Image settings screen, select the number of desired patches for the test chart and whether the corner points should be added as well.

Delete: Removes the selected files from the Data Sets window. However, the files are not deleted from the hard disk.

Clear History: Removes all entries in the History window.

File

Under File you can open, save or export data in various formats.

Save As: Saves files in the following formats:

  • CGATS text file (txt)
  • CGATS XML file (xml)
  • Named ICC profiles (icc)
  • Color Exchange Format (CxF3)
  • Photoshop Palette (aco)
  • Adobe Swatch Exchange (ase)
  • GMG CSC file (csc)

Special features of the formats:
Named Color Profiles are special ICC profiles that are intended for spot color tables. They contain the CIE and DCS values in addition to the color name.
ACO and ASE files can contain either CIE or DCS values. Therefore, when saving in one of the two formats, a message appears to select which data should be saved.
CGATS files can contain different specifications in one file, e.g. measurements from different test charts or different color spaces. ColorAnt supports multiple tables in CGATS files. A typical use case would be the export of various Lab values of converted spot colors from the Spot Color Report feature in ZePrA and their import to ColorAnt for further inspection.

Duplicate: Creates a copy of the selected file.

Export Lab/XYZ/Density/CxF/X-4: Data can be exported in the following formats:

As Lab, XYZ, density in formats such as CGATS text files (txt) or Color Exchange Format (CxF3).

For more information on this format, see the help on Export CxF/X-4.
