Example of a typical Color Set Details pane

Once you have measurements of your devices uploaded into Maxwell, there is a great wealth of information that you can obtain. You have several different options for viewing your colors.

To access the Color Set Details click on a track, choose Measurements, choose an individual measurement, and see the list under "Related Items." This page explains in detail what you can do with a measurement or other color set.

Channel Report

Channel Report

The Channel Report uses SmartTargetTM technology to:

Note: Channel Report requires CMYK data. (It will not work with RGB data.)

Solid Colors

Solid Colors

The Solid Colors report uses SmartTargetTM technology to pull key patches from the target, including:

This feature provides a quick and easy way to view these important colors without having to remember where they are on the target.

For example, you can check to see if your paper has any optical brighteners by quickly choosing the paper white patch and viewing the histogram.

Note: These patches must exist in the color set in order for Maxwell to find them!

Target View

Target View

Target View will display the target colors in the correct dimensions if Maxwell can recognize the target contents.

In addition, you can:

Clicking again on any color in the target will

Digital PressWatch and HeatMap

Example of a heatmap showing a bad Pip on an Indigo digital press.

The Target View is instrumental in the Digital PressWatch service of Maxwell. Here a target printed over the entire width of the press can help to visually identify variations in color consistency.

The example at right demonstrates what a Digital PressWatch target would look like identifying a worn blanket on an Indigo digital printer.

ab Plot

ab Plot

The a/b Plot is a representation of the colorset as it would be seen in Lab colorspace. This is a 2-dimensional view of your colors showing hue and saturation (but not lightness.)

All the colors shown in Maxwell are taken from the actual color data itself, converted to sRGB in order to be viewed correctly on internet browsers.

Results Summary

Example of a typical Results Summary pane.

The Results Summary pane is a very powerful tool which can be used to diagnose problems and identify what colors are falling outside of the metric tolerance.

Metric Summary

The Metric Summary duplicates the metric results as they would be seen by the label printed by the Maxwell Client.

dE Histogram

The delta E histogram will confirm which delta E calculation is being used here: dE2000 or dE76.

The histogram identifies which delta E result occurs most often in the data, providing you with a typical "bell curve" - popular for identifying trends in data.

Patch to Patch Comparison

The Patch to Patch Comparison provides a direct comparison between the reference patches and the corresponding sample patches. This includes:

Quadrant of color from +a to -a and +b to -b


Note that each of these columns are able to be sorted. Here are some examples of how to use this powerful feature:

  • For example, if you click on the "dE" column header, all of the colors in the list are sorted according to smallest to the largest dE values. Clicking the dE heading again will sort them all from highest to lowest. This is very useful for quickly determining the worst colors and identifying common characteristics.
  • Click on the "DeviceValues" header to order the list according to device values. You can quickly identify if your color list contains duplicate patches.
  • Click on the one of the Lab headers to sort all patches according to luminosity.
  • By default the Patch to Patch comparison matrix is sorted according to patch order in the reference file. To return to this sorting, click on the # heading over the left-most column.
