printing from an ICM function-compatible application.

matching using applications such as Adobe Photoshop, or printing using a profile creation tool or

Relative Colorimetric
When image data is converted to the color space of the printer, this method converts the image
data so the color reproduction approximates the shared color regions. Select this method to print
image data with colors that are close to the original colors.
The white spots are reproduced as white spots (background color) on the paper.
Absolute Colorimetric
This method uses the white spot definitions in the input and output ICC profiles to convert the
image data.
Although the color and color balance of the white spots change, you may not be able to get the
desired output results because of the profile combination.
