Measure test charts

Measure Tool

The Measure Tool is ColorLogic’s own tool for measuring test charts and spot colors. It can be opened in ColorAnt by selecting Measure in the Sidebar.

Device

Selection: Select your device and connect it to the Measure Tool by clicking Connect.

Info: Shows the current device information (if the selected device was found, version number and if the built-in filter is active).

Options: Use Direction to specify how you want to measure the chart. Depending on the selected device, single field measurements or strip measurements in horizontal or vertical direction are available.

Evaluation: Allows you to compare the measured data with a profile of your choice. Click on the Gear icon and select the comparison profile from the list of profiles available on the system. All patches with a DeltaE deviation higher than 20 are highlighted in red on the chart. By default, evaluation is disabled.

Note: To deactivate the evaluation after activation, select the first entry Deactivated in the profile selection.

Chart

Selection: Here you can select either predefined charts or charts stored in the ColorAnt wedges folder (User\Documents\ColorAnt\Wedges) from the list. Alternatively, simply load a reference file or drag and drop it onto the window.


View: Show reference data allows a split view of the patches. One half shows the reference color value the other the measured color value.
Fit to width: Uses the width of the window to show the chart. For larger charts, a scroll bar appears on the right.

Chart display area

The lower part of the window shows the selected chart with row and column numbers. The last measured patch or row is marked with a yellow frame. If Evaluation is turned on measured patches with a high DeltaE variance are marked in red.

Info icon: Displays some useful information about the chart, such as the name of the reference, the number of fields, rows and columns of the chart. This information is useful for some devices, for example to set them up quickly and easily.

Delete icon: Deletes all data measured so far and displays the chart with the reference values.

Transfer icon: Opens the Transfer measurement dialog. Here the measurement data can be discarded or transferred to ColorAnt.

Patch information: When hovering the mouse over a color patch, information about the respective patch is displayed, such as the patch number, the color space including reference values and measured values. When comparing with a profile, information about the DeltaE deviation is also displayed.

Notification messages: On the left below the display area you will see various notes and messages about the current measurement. For example, when measuring charts, there may be instructions about changing charts, or a message indicating a questionable measurement in a row (e.g. when the wrong row has been measured).

Help icon: The help icon on the bottom right takes you to ColorAnts Online Help with a single click.

General Information about measuring 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.

 

Virtual Device

ColorAnt’s Measure Tool includes a Virtual Device. It is used for demonstration purposes.

Measurements using the Virtual Device

Step 1: Select the device from the drop-down list Selection on the Device tab.

Step 2: Click on Connect.

Options: Are available once the Virtual Device is connected. Select the Direction of the scan.

Condition: M0, M1, M2, M3.

Procedure

Step 1: Start a measurement by double-clicking on the first patch of the first row.

Step 2When the measurement is complete, click on the Transfer icon to open the Transfer measurement dialog. Here the measurement data can be discarded or transferred to ColorAnt.

If several measurement conditions have been used, the results/measured values of the individual conditions can be selected and viewed in the drop-down menu next to the Transfer icon.

ColorAnt allows to transfer individual or all available measurement conditions. In the latter case, several data sets are transferred. For easy differentiation, the measurement condition is appended to the file name of each data set.

Note: The Virtual Device is for test purposes only and will simulate the same stored data each time.

Barbieri Spectro LFP

Measuring with the Barbieri Spectro LFP

Step 1: Select the device from the Selection drop-down list in the Device tab.

Step 2: Click Connect.


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.
Steps: Indicates the units that the measuring head covers when an arrow is clicked.
Position: Change the position of the head by entering x/y coordinates.

Once you are finished, click Next to specify the upper right corner of the chart.

Confirm with Next.

On the last page, enter the position of the lower right corner and confirm with Next.

Settings

Rows per page: Enter the number of rows on the test chart page. If the test chart consists of multiple pages, enter the number of rows on the first page.
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.
