ColorAnt’s Measurement Tool Window

Open the Measure Tool by clicking on Measure.

When measurement data is loaded into the Data Sets window and Measure is selected, the previous chart and measurement device by default are automatically loaded into the Measure tool. After measuring is complete a dialog box will open. Transfer the measurement data to ColorAnt by clicking Transmit.

 

Device Settings

Selecting a measurement device: Select the measurement device and click Connect.

Info: A list with all available information is shown here. This may include serial number or the activation of a Filter.

Options:

Direction: defines in which directionto measure the chart. Depending on the device you may choose single patch, horizontal or vertical.
Evaluation: This Option allows comparison of measured data with a profile defined by the user.  Click the gear symbol and choose from the list profiles available. Patches with a large Delta E variance are highlighted with a red frame.

 

Tip: To deactivate the evaluation, select the first entry – Deactivate.

 

Chart Preferences

Selection: Either select one of the predefined charts or a chart saved in ColorAnt’s Wedges folder (User\Documents\ColorAnt\Wedges). Load a reference file or “Drag&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 at the right side shows.

Measurement: Delete measurement deletes all existing measurement data and shows the chart with reference data.

Chart visualization

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 helpful information about the chart. The name of the reference file, number of patches and amount of columns and rows.  For some devices these information are essential for the setup.

Patch information: In the upper right corner of the visualization area you may get information about single patches as soon as you cross it with the mouse cursor. This includes patch number, color space including reference and measured values and – if comparison with a profile is active – DeltaE differences.

Power user tip: the lower left corner shows different information for whatever device is connected (e.g. place the next page on the device)  questionable measurements (e.g measuring the wrong row).

General Information about measuring conditions

 

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

M0: does not define a specific light source but recommends lightning condition A. The lightning condition represents common light sources with a tungsten filament with a color temperature of approximately 2856 Kelvin. The UV part is not clearly defined. M0 should not be used, based on ISO 13655 if the measured paper contains fluorescence and if measurement data needs to be exchanged between different locations.

M1: minimizes differences between different measurement devices if the substrate contains optical brightener. The used light source must be D50 which means a simulation of daylight with a color temperature of 5003 Kelvin. The irradiation intensity of the wavelength are clearly defined including the ones below 400 nm which activates fluorescence.

M2: also known as “UV-cut”, uses either an additional filter used in front of the optic of the measurement device or modifies the light source in a way that only radiation energy over 400 nm will be used. Fluorescence will not have any influence on the measurement results.  

M3: a polarizing filter will be used to suppress glossy effects on measurement data. All other requirements are similar to M2.

The ColorAnt Measure tool directly measures test charts for profile creation.

Productivity Feature:

When measurement data is loaded into the Data Sets window and Measure is selected, the previous chart and measurement device by default are automatically loaded into the Measure tool.
