Use this dialog to configure how ThumbsPlus will use color matching profiles to best represent image colors on monitors and printers. For more information on color management and color profiles click here. To read information at Microsoft regarding color management click here.


Profiles folder. This field displays the current windows folder that contains installed color profile ICM files.


Device profile associations. Lists all the color profiles currently installed. Double click a device OR click the [Change] button to set its active profile.

Rendering Intent. Lists the rendering intents you can use. A rendering intent maps the colors of an image to the color gamut of a monitor or printer. The color gamut is the range of color that a device can produce.


Relative Colorimetric (Proof) is the best for logo images, in which a few colors must be matched exactly. The colors that fall within the gamuts of both devices are left unchanged. However, other colors may map to a single color, resulting in tone compression.


Absolute Colorimetric (Match) is used for mapping to a device-independent color space. The result is an idealized print viewed on a perfect paper with a large dynamic range and color gamut.


Perceptual (Picture) is the best for photographic images. All the colors of one gamut are scaled to fit within another gamut. The relationship between colors is maintained.


Saturation (Graphic) is the best for graphs and pie charts, in which vivdness is more important than actual color. The relative saturation of colors is maintained from gamut to gamut. Colors outside the gamut are changed to colors of the same saturation, but different degrees of brightness, at the edge of the gamut.
