Color Proof
The various systems for reproducing colors cannot represent the infinity of colors available. Even if there are many colors in
common between the various systems and nature, some of the colors will not be the same. The ‘gamut’ is the color range of a
system. Color Profiles allow you to compensate for these differences.

Before you print an image, it may be useful for you to see if you will get the result you want by applying a profile. The ‘Color
Proof’ filter shows you how your image will look after a color profile has been applied.

OPTIONS
Intent You can apply the filter you have selected in one of four ways:
Perceptual The Perceptual method is the best way to reproduce photographs on ink-jet printers. The adjustment is mini-
mal and visual relationships between colors are preserved so that they are perceived in a natural way by the human
eye.
eye.
Relative Colorimetric This method compares the white and black points of the source gamut with those of the destination
gamut and scales the hues accordingly. It is well suited for printing photographs on ink-jet printers. It tends to darken
the image, so it may be necessary to compensate the black point.
the image, so it may be necessary to compensate the black point.
Saturation This method preserves the saturation values of the original pixels. The original pixels which are outside of
the range are all represented at the same saturation. This method is not very useful for photographs. It is used for
documents where color punch is more important than accuracy, such as for reproducing logos. Colors which should
have a continuous change are not represented very well, since there are jumps in the colors.

Absolute Colorimetric This method leaves the colors of the source which are within the gamut of the destination un-
changed and discards the colors outside of the gamut. There is no stretching of the colors on the white point. The
accuracy of the colors is preserved, but not their relationships, and different colors may be represented in the same
way.

Profile This text box and its browser button allow you to select the profile you want from a location on a storage device.
Black Point Compensation Black point compensation resamples the image to scale the hues from the black point of the original
image, if the result is too different from the original.
