How do I find out how far out of gamut my image (or color list) is from my output profile?

I need to have quantifiable data, such as delta E differences.

The problem

You need to know how far one color is from another color. More specifically, how far a color is from the gamut boundary of a printer profile with which you intend to print the color.

This procedure can be done with either a picture, a portion of a picture, sampled colors from an image, or a color list you make up yourself.


The solution

  1. Bring your image or color list into ColorThink Pro. (It opens automatically in the Worksheet.)
  2. Choose the eye dropper and select the colors in the image you wish to sample. A color list is automatically populated below in the "Colors" section.
  3. Click and drag your printer profile onto the image in the Worksheet. This reflects what will happen to the colors of your image when it gets printed.
  1. Click on the "<untitled list>" drop down box and you can choose to save out your list (optional) or choose "Graph List."
