  • A bug in the White Correction tool in combination with XYZ measurements has been fixed.
  • Fixed channel naming issue and corrupted file with multicolor TIFF files after exporting with the Export Chart tool. 

ColorAnt 4.1 Release | May 2017


Key Features

The Edit Primaries tool has been updated to allow the assignment of new color values to device values (DCS values) which do not already contain color values. Thus, new characterization data can be created which is based only on existing wedges of primaries or on the input of Lab values. There is no longer a need to reprint test charts.

Procedure:

  1. Open a reference file (for example IT8/7-4) and, if available, measurement wedges or existing characterization data of test charts containing the desired colors.
  2. Select the reference file, click on Edit Primaries and use the eyedropper tool to choose colors from the pool of measurement values.
  3. Alternatively, fill in the Lab value if there isn’t other data available. The best results are achieved using spectral values, wedges or information on overprints.
  4. If measurement values are assigned to all primaries and the paper white, and click Start.

Export CxF/X-4 Feature

A feature to automatically optimize and remove redundant color patches has been added to the tool Export CxF/X-4 in the File menu (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.

Bug Fixes ColorAnt 4.1


Bug fixes – Measure Tool:

  • The Measure Tool now remembers the last used settings of each measuring device.
  • When using the X-Rite i1iO, measurement table older i1Pro measuring devices (Revision A-D) are now supported as well.
  • For measurements using X-Rite i1iO with newer i1Pro measuring devices (Revision E) the default setting is now M0 (Dual). In previous versions, the default setting was M0 (single) which resulted in slow single patch measurements if users did not change the setting manually.
  • Measurements of multi-page test charts using the X-Rite i1iO are working properly under MacOSX.
  • An error has been resolved in which a recurring message appeared when the drop-down menu for the measuring direction has been selected during a measurement using the Konica-Minolta FD-9.
  • Several messages have been translated.

Bug Fixes – Export Chart

  • The option Randomize of the feature Patch distribution has been revised and now works with multi-page charts. Additionally, remaining white patches are no longer listed at the end, but will be spread across the chart. Furthermore, light measurement patches at the edge of the chart are also avoided. These measures increase the measurability of such charts especially if Patch delimiters are not activated.
  • An error has been resolved in which the size set in millimeters in Patch delimiter was not transferred correctly into the created chart.
  • An error has been resolved in which the target definition for basICColor catch was not generated despite the option Create Target Definition for basICColor Catch being activated.
  • The minimum Patch height for strip measurements of test charts using the X-Rite i1iO has been corrected to 7.5mm in the default Preset (Default – Minimum Patch Size).
  • The Chart width and Chart height for measurements using the X-Rite i1iO has been increased to 320x230mm in the default Preset (Default – Maximum Chart Size).

Bug Fixes – CxF support:

  • An error resulting in unusable color values or missing DCS values when saving some multicolor data as CxF has been corrected.
  • The support of CxF files from X-Rite i1Profiler which have proprietary extensions but are in fact CxF files has been optimized. (Ticket #170116)

The compatibility to CxF measurement values of different manufacturers has been optimized.

 

Bug Fixes:

  • The feature Apply redundancies correction after averaging added to ColorAnt 4 in the tool Averaging had an error. This error has been corrected. (Ticket #170105)
  • The Correction and Smoothing tools had an error in the processing of measurement data which contained only color wedges of primaries. This has been corrected.
  • When editing the black point of RGB or 3CLR measurement data using the tool White/Black Correction the black point is now calculated correctly. (Ticket #170104)
  • Channel names have not been detected correctly in some 4CLR measurement data. This has been resolved provided that channel names are noted correctly in the document.
  • In the tool Tone Value, it is now possible to apply Corrections according to ISO 20654 on 2CLR measurement values.
  • The drop-down menu option Correction according to a tone value curve of an ICC profile in the tool Tone Value is now grayed out when no ICC profiles matching the measurement values have been found. This prevents inaccurate artifacts and error messages.
  • The display of color space expanding colors of a multicolor comparison profile in the window Spider Web under View has been optimized. The colors of comparison profiles are now displayed brighter for a better identification of the measurement data.
  • The import of spot colors from PDF files that don’t contain CxF/X-4 measurement data has been optimized.

 

ColorAnt Release | 2017


Key Features

  1. The Measure Tool supports additional instruments such as X-Rite i1iO, X-Rite eXact and Konica-Minolta’s ultra fast strip reader FD-9.
  2. Improved usability of the Custom Chart tool.  We have added an expert system that provides guidelines for typical use cases such as creating linearization test charts, profiling test charts, special profiling test charts for Flexo printing and updating of profiles. The new options answer the typical question of how many patches should be used for a desired test chart.
  3. The Export Chart tool has added functionality to create printable test charts as PDF, TIFF or PSD files that are best suited for the supported instruments in Measure Tool. In addition individual settings can easily be saved and reused.
  4. The Edit Primary tool has been improved for better prediction of overprints using the new Printing Sequence feature.
  5. The previous White Correction tool has been updated to the White/Black Correction tool. It adds functionalities such as selecting the white point from another data set, improved spectral calculations and adding black point editing.
  6. The Tone Value tool allows correction choices for G7 and the new ISO 20654 methodology of colorimetric based linearities used for spot colors instead of density calculations. Even G7 + ISO 20654  is possible for Multicolor files with CMYK+spot ink channels. This is especially helpful to handle expanded gamut color including CMYK and spot color gradations.
  7. The Views have added support for comparing the Spider Web, 3D gamut ,TVI and Curves with another profile. Curves allows to compare TVI versus ISO 20654 (aka SCTV) curve shapes.
  8. The Online Help has been updated to a new platform
  9. There are several improvements to various tools such as the Correction tool, which has a Protect lights feature similar to the Smoothing tool. The new Averaging tool allows automatic application of redundancy correction after averaging, which ensures that this easily missed step is not forgotten.
  10. CxF file support has been improved and a new option to export spot colors as CxF/X-4 files added. In addition, spot colors as CxF/X-4 or Lab based can be extracted automatically from loaded PDF files.

Measure Tool

The Measure icon in ColorAnt 4 opens up the new Measure Tool that has replaced UPPCT. Measure Tool is ColorLogics own tool for measuring charts and spot colors providing advantages both in features as well as usability and it is extremely simple to use. It behaves the same as UPPCT, e.g. start it from ColorAnt and measurement data is transferred back to ColorAnt after measuring. The following instruments are supported:

  • Barbieri Spectro LFP
  • Barbieri Spectropad
  • Konica-Minolta FD-7
  • Konica-Minolta FD-9 – strip reader
  • Techkon SpectroDens
  • Techkon SpectroJet
  • X-Rite i1Pro 2 /i1Pro
  • X-Rite i1iO
  • X-Rite eXact

Measure Tool Window

Custom Chart

Custom Chart Window

To define a custom test chart for profiling a reference file containing the device data for the desired color space is required. The Custom Chart tool is designed for creating the reference files for test chart generation. With the help of the Mode function you can select between different use case to create targeted test charts. Simply select the desired uses case from a drop down menu for general Profiling, Profiling of Flexo printers using more patches in the highlight regions, Updating of Profiles using a small amount of representative

patches and test charts for Linearization purposes. After selecting the Mode you can select the desired Number of Patches from a drop down menu that allows to select either between small, medium or large or a custom amount of patches. The number of patches is dependent  on the selected Color Space and  Mode and will be displayed right next to the drop down menu.

Export Chart

The Export Chart tool allows creation of test charts as TIFF, PSD or PDF files to be printed on a printer. The tool is optimized to work with most of the instruments that our Measure tool supports.  The new Preset selection feature allows selection of presets for the supported instruments and typical page sizes.  As each instrument has its own requirements for Patch Sizes, Distribution and Delimiters those settings are already preset for you to make things simpler. Changing settings including Chart dimensions and patch sizes to create test chart files for a particular printing space and instruments requirements is a simple task.

Export Chart – New Features

Additional options are helpful for specific cases such as creating not only the test chart file itself but a XML reference file to be used for measuring the test charts with basICColor Catch as well. 

Edit Primaries

The Edit Primaries tool allows addition, removal and and exchange of primaries or the paper/substrate into an existing measured printer characterization data. In typical print production, adding or swapping ink(s) requires the of printing a full blown test chart. The Edit Primaries tool will simply require the spectral data of the new ink(s) to be added or exchanged to avoid printing of new test charts. Edit Primaries will not only exchange the inks but also recalculate all overprints based on intelligent spectral color models. A great new addition to the Edit Primaries toolset is the Printing Sequence feature. It takes the order of the inks printed on top of each other into account so that exchanging of primaries respects the position of the inks and adjusted overprint calculation is applied.

Edit Primaries New Features


As an example: There is a difference in color appearance if red ink is printed on top of yellow ink or if it is vise versa. Users can define the printed ink sequence independent from the channel order, so that the channel order can be retained as CMYK even if the printing sequence was KCMY.  With the Printing Sequence feature, it is easy to evaluate a different printing sequence by simply moving the colored icons to a different position and recalculation of the data without actually having to print that new sequence.

White and Black Correction

This tool allows to change the paper according to three different methods.  A new eye dropper feature has been added to the White Correction part to pick an other paper white from a loaded measurement data file. This makes adaptation of a given printer characterization data to a different paper white very easy. In addition, if both the characterization data of the printer and that of the different paper white are spectral data and the ColorLogic default method is selected, calculation is done with a spectral model leading to the best results. In addition, industry wide used Methods like paper adaptation according to ISO 13655 or relative colorimetric are available.

White and Black Correction

Another new feature is the ability to edit the darkest neutral patch of the loaded characterization data under Black Correction. This can be helpful in cases where black has been measured to dark or to light compared to the visual appearance, which may happen in industrial applications like ceramics, textile, glass, etc. Users can change the darkest black, which will scale the entire data towards the edited black point.

Tone Value

The Tone Value tool has been enhanced with additional options. It offers not only corrections according to G7 but according to ISO 20654 and even a combination of both now.

With G7 Gray Balance, the tone value curves are calculated to match the gray balance requirements of the G7 calibration process. The G7 calibration process ensures that the CMY curves reach a neutral gray of defined lightness values throughout the entire gray balance curve.

Additional Tone Value Options

The new ISO 20654 methodology of colorimetric based linearity can be used for spot colors instead of density calculations but  can be applied for CMYK, also. Using this method will make sure that the gradations of all primaries are colorimetrically linear. This can be verified using the View/Curves dialog and selecting the ISO 20654 viewing method.

Note: Density based methods, like Murray Davis, do not work well for non CMYK colors. The IS0 20654 method also known as SCTV (Spot Color Tone Value) is an alternative method to handle tone values of spot colors.

G7 + ISO 20654: G7 is defined to work with CMYK only. However it is possible to apply the G7 process on the CMYK parts of a multicolor measurement file and the additional (multicolor) channels will be corrected according to ISO 20654.

New View options

The Curves tab displays the linearity curves from white to 100% of all primary colors including multicolor data and in case of CMYK data, the secondaries also The smoothness of gradation curves can also be displayed using three different methodologies. Three different methods can be selected: ColorLogic Default is the default option.

ColorLogic Default: views the curves in colorimetric linearity based on Lab /dE-76 and means that for example a 50% value of a given primary has the same distance to left value (white) and the right value (full tone) if it sits at the midpoint of the graphic. Nowadays modern RIPs linearize primaries based on colorimetry methods. A fully linear curve (45 degrees) points to a perfect colorimetric linearity.

ISO 20654: The new ISO 20654 methodology can be used to display how the gradation curves of primaries look like if regarded under the aspect of colorimetric linearity. A fully linear curve (45 degrees) points to a perfect colorimetric linearity according to ISO 20654.

Note: Density based methods like Murray Davis do not work well for non CMYK colors. The IS0 20654 method also known as SCTV (Spot Color Tone Value) is an alternative method to display tone values of spot colors.

Tone Value (Density): is the tone value curve based on density. It’s a different view of TVI diagrams. We have added this view for a better comparison to colorimetric methods.

By using Compare with ICC profile you may choose a profile for comparison of the curves in the DropDown menu.

Correction

The Correction tool has a new Protects Lights feature that allows selection of which percentage value the correction shall be performed. Values below this slider are protected. The slider values ranges from 0% to 50%.

Features for flexographic printing: The flexographic print processes often exhibits a bump curve in the  highlighted area. These types of curves can be retained by using Protect Lights. Use the slider adjust unwanted changes in the highlights after correction.

Averaging

The Averaging tool has a new option, Apply redundancies correction after averaging.This feature is enabled by default and is helpful if a chart contains redundant patches since they could still be different in the averaged file. Using this option saves you the extra step of a using the Redundancies tool after averaging.

Additional Averaging Options

Extended CxF and spot color support

The File menu offers an Export CxF/X-4 option. It extracts any primaries, including gradations and overprints on black and saves this as a CxF/X-4 compatible file. Such a file can be used in other tools to integrate in a PDF file or it can be loaded into a spot color library in the color server ZePrA for conversion of spot colors.

The Export dialog offers possibilities to enter meta data in the exported file such as Printing Process, Substrate Type, Finishing and others.

Export CxF X-4 Options

In addition, ColorAnt 4 allows extracting of any spot color from PDF files. Simply drag and drop a PDF file with spot colors in the Data Sets section and all spot colors, be it CxF/X-4 or those with alternate color space, will be loaded as separate files. This is a helpful feature to examine the color values of spot colors used in PDF files or to extract such values to be used in other tools.

New Online Help

The new online help website is designed responsively to accommodate mobile devices

ColorAnt 3.2.2 Release | December 2016


Bug Fixes

  • The installer of ColorAnt 3.2.2 comes the latest version of UPPCT v2.3.5 that supports X-Rite eXact instrument.
  • The Comparison tool has been optimized. It not only shows the Lab values of the selected patch and the delta E but the device values (DCS values). This is useful for analysis in cases where DCS values have been changed.
  • Compatibility for CxF/X-4 files from third party vendors has been added. CxF/X-4 files can now be loaded and correctly displayed. (Ticket# 268245)
  • The Redundancies tool has been improved. The order of processing has been changed. First redundant white patches are averaged, then gradients are optimized and finally all remaining redundant patches optimized. (Ticket# 145121)
  • An error has been fixed in the Link tool when combining CMYK and multicolor files in combination with a license error.
  • Renaming of channels with Edit Primaries has been fixed in cases where files contain differing white patches that have not been optimized for redundancies.
  • The Windows version of the Export Chart error that multi page PDF test charts couldn’t be exported has been fixed.

ColorAnt 3.2.1 Release | August 2016


Bug Fixes

  • Manual editing of a channel via typing in a new LAB value does work again in Edit Primaries. In the previous version the LAB values did not change.
  • Fixed a crash of ColorAnt when saving an XML report with a comparison profile enabled in the report settings.
  • Fixed Argument Error in case of exporting 4CLR charts with Export Chart tool. In addition it is possible now to export PDF files for multicolor testcharts without CMYK components.
  • Optimized handling of mixed spectral and Lab data in Edit Primaries tool leading to better overprint and gradations calculations.

ColorAnt 3.2 Release | May 2016


Key Features

Overall enhancements to ColorAnt

  • The quality of the core technologies Correction, Smoothing and Rescaling has been improved. For example Smoothing with a 100% slider setting is behaving stronger now compared to the previous version and still more accurate.
  • Improvements to Export Chart: the distance between the numbering of the rows and the first patch on that row in the exported tests charts was increased. This makes measuring these charts with certain instruments, e.g. Konica-Minolta FD-7 easier.
    Note: The instruments head should not be placed on any of the numbers or incorrect readings will result. Make sure to place the instrument on the blank space between the numbering and the first patch of a row.
  • Support loading of measurement data from ICC profiles using the CxF tag for storing measurement data. E.g. X-Rite i1Profiler saves the measurement data this way.
    Note: Some profiling tools save the measurement data needed to build the ICC profile within the profile. A standard tag for this is the TARG tag. ColorAnt is able to load such data from ICC profiles if available and will show an error message if no such data is existing.
  • The spider web diagram allows to select RGB working space profiles (e.g. AdobeRGB or sRGB) as comparison profiles now. In previous versions only printer profiles were supported for comparison.

Additions to the Link Tool

The Link tool has been redesigned and one new option added. There are three options available now. The options are grouped with radio buttons that are enabled and disabled automatically depending on the data sets. Read more about the Link tool here

Reordering Channels using Edit Primaries

The Edit Primaries tool can be used to exchange, add and delete channels in a measurement data file. With ColorAnt 3.2 and higher it is possible to reorder the channels without changing the measurement data. One example is if you add Orange as a 5th channel and Green as a 6th channel to a CMYK data set.

But later on you decided that the channel order should be CMYK+Green+Orange. Now you can simply exchange the channel order by using the pipets icon and selecting Orange for Green and Green for Orange from the same measurement data file without the measurement data changes. If channels are only reordered this will be indicated with adding ChannelOrder to the file name.

Reordering Colors with Edit Primaries

Reordering Colors with Edit Primaries

Note: The channel reordering feature in Edit Primaries and the new Link tool Merge by Channel Name can be used combine multicolor measurement data from different sources. For example it allows to combine the four separate 4 color Esko Equinox files to a 7 color multicolor data set that can be used to generating profiles in CoPrA.

Support loading and displaying of CxF/X-4 data

The CxF3 file format has been supported since a longer time in ColorAnt already. With ColorAnt 3.2 we support to load and display CxF/X-4 data for spot colors, too. Saving as CxF/X-4 is not yet possible in ColorAnt.

ca32_cxf-x4-400x287

Note: CxF stands for Color exchange Format. CxF files area 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.

Bug fixes

  • Fixed unwanted conversion of separation color space Black during transparency reduction in cases where the color Black is defined with an ICCbased alternate color space. (Ticket #532456)
  • Improved speed of file copying from a temporary folder on the Mac into a destination folder on a remote Samba server. (Ticket #526142)
  • Fixed a case where processing of a PDF file was cancelled with an error. (Ticket #191023)
  • Fixed occasional job errors under Enfocus Switch on the MacOS due to zcmd accidentally running in 64 bit mode. (Ticket #326764)

ColorAnt 3.1.1 Release | November 2015


Key Features

  • A new feature, Clear entries, has been added to the list File/Open Recent. ColorAnt remembers the last 20 files. With Clear entries they all can be deleted to reset ColorAnt if required.
  • ColorAnt now supports the CGATS XML file format. The CGATS specification supports both a TXT and XML format and so does ColorAnt.
Support for CGATS XLM files

Support for CGATS XML files

  • The tool Export Chart allows to save exported test charts as a TIFF or Photoshop PSD file and now also as a PDF file.
  • When exporting single page test charts with the Export Chart tool, ColorAnt uses algorithms to evenly spread the patches on the page. This may lead to a layout that does not use the maximum chart width. If you wish to force the usage of the chart width, you simply enable the new option Always use full chart width.

ca31_exportchart-400x397

  • The ICC Transformation tool now allows selection of an abstract ICC profile for conversions.
    Note: Abstract profiles are a special type of ICC profiles that perform a direct Lab-to-Lab conversion such as special effects or Lab modifications.
  • All tools are now optimized in a way that the Start and/or OK button is highlighted. This allows application of a tool by hitting the enter key.
  • A new version of the measuring tool UPPCT v2.3.3 is included in the installer. The new version fixes an issue with multicolor measurement data that was not transferred to ColorAnt or CoPrA.

Improved CxF support

The CxF3 file format is predominantly used for exchanging spot colors. ColorLogic has improved the CxF3 import filters to be compatible with the recent ISO standard 17972-1:2015. In addition, a second ISO standard, 17972-4:2015, for the exchange of spot colors with tints. ColorAnt also supports the import of compatible with CxF/X-4 files.
Note: Older CxF versions are no longer supported by ColorAnt.

Enhancements to White Correction tool

The White Correction tool is predicting the impact of paper white changes to the measured values of a test chart. With ColorAnt 3.1 there are three different methods to calculate this effect. ColorLogic Default is still recommended as the default setting. The two other methods available are ISO 13655 and Relative colorimetric.

Three methods of White Correction now available

Three methods of White Correction now available

Relative colorimetric effects are strongest because paper white changes will modify the entire color space. In case of major changes in the paper white this will also massively effect the primary colors. The ISO 13655 method is still similar in the highlights and colorful primary colors to relative colorimetry. However, this method assumes that the shadows and very dark colors are not changed. The ColorLogic Default method, we proceed like in ISO 13655 and assume that the shadows are not effected and that there is a much lower impact on the primary colors. Due to our experience this corresponds more to the real observation.

Additions to the Edit Primaries tool

A progress bar has been added to the Edit Primaries tool to the display.

When replacing the Substrate or Paper white, the change does not affect the primary colors. This is done on purpose, because the tool is intended only for smaller paper white changes from which the full tone of the primary colors would not be effected. For this reason, additional information will be displayed in the dialog. To make major changes to the paper white, we recommend correcting with the White Correction tool before editing the primary colors.

Until now, only primary colors could be exchanged with other colors when the reference and measured values for the color to be replaced were present in the loaded data file. With spot color libraries such as the Pantone libraries, which can be opened as a CxF file in ColorAnt, there are no reference values. Therefore the exchange was impossible in former versions. With ColorAnt 3.1 you can use these spot color libraries for the exchange of primary colors. Each spot color in the library is interpreted as full tone and can be selected to replace a primary color.
Note: If only the full tone for the exchange of a primary color is available but no gradation values, ColorAnt will use the gradation behavior of the original primary color.

Use spot color libraries within ColorAnt

Link Took – Combine separate reference and measurement data

A similar task to the reordering  some third party tools save the measurements without the reference data. Without reference data, neither ColorAnt can work with the measurement data nor can CoPrA create an ICC profile. In order to combine or link the separate reference and measurement data files they must have the same patch count. Simply load both files in the Data Sets section select them and click the Link tool to combine them to one file.

Combining CIE with DCS data with the Link tool

Reordering measurement data

ColorAnt 3.1 enhances the capability to create and reorder test charts for 3rd party tools with the Swap Rows with Columns feature. By right clicking on the data set, six options are available. This feature will enhance compatibility with third party software.

Note: Open the 2D-View to verify the results of the reordering applied. If there is an issue with reordering simply click the  History entry to revert the data.

Bug Fixes 3.1.1


  • Error message when trying to use the CIE Conversion tool have been fixed.
  • When creating a single patch reference file with the Custom Chart tool a full tone will be created instead of 50%.
  • The progress bar when creating a PDF report now more accurately displays processing time.
  • Using Rescale tool in a previous versions to for small chart into a larger one, the linearity and TVI curves were smoothed. The curves will now closely match those of the original file as good as possible (depending on the fulcrums available in both charts).
  • The selected rendering intent in the ICC Transformation tool will now be applied correctly.
  • Third party measurement files with an unknown syntax will not crash ColorAnt. When an unknown syntax occurs, an error message will be displayed.
  • Fixed file saving options.In the previous version only the TXT file format was accessible.
  • Fixed viewing of some CxF3 files in 2D View. Now the patch name and Lab data is shown correctly.
  • Fixed CxF3 import of a 3rd party CxF3 file with an unnecessary complexity.
  • Improved performance for importing, viewing and processing of large CxF3 files without device data. This improves processing and viewing large spot color libraries with spectral data.

ColorAnt 3.01 Release | May 2016


Bug Fixes

Chart width in the two Presets we deliver in the Export Chart tool. This allows for better reading with the ruler of the X-Rite i1Pro.

  • A crash when exporting multi page Multicolor charts with the Export Chart tool has been fixed.
  • Optimized dark Patch delimiters used between color patches with non-CMYK test charts exported with the Export Chart tool. Now we do not use the color of the fourth channel any more but use rather darker colors needed for strip measurement instruments.
  • Potential customers downloading ColorAnt and wishing to see which kind of features it offers can now do so without loading a license file. In certain dialogs a warning message may pop up telling the user that further actions can only be done with a valid license file (for example a demo license). Without licensing saving any files is not possible. Details on requesting a demo license can be found here.
  • Issue with incorrect display of IT8 formatted measurement data files provided from third party instruments (e.g. multiline quoted values from Barbieri Gateway) have been fixed. Minor syntax errors in some third party files that prevented ColorAnt from opening them have been fixed. Now ColorAnt is more tolerant with such files and will open them.
  • The incorrect channel names shown for the Multicolor test charts and reference files supplied with CoPrA after loading in ColorAnt and measuring with UPPCT has been fixed.
  • Some memory leaks have been fixed.
  • ColorAnt was not able to display measurement data when no system profile defined in the OS. ColorAnt will use a default conversion to display measurement data when no profile is found.
    Note: ColorAnt by default utilizes calibrated monitor profiles to properly display measurement data. ColorLogic recommends a calibrated and profiled monitor to enhance the user experience.
