rendering intent and saturation slightly in the process. Colors are mapped smoothly, avoiding the loss of distinction between similar shades, which other rendering intents may map to the same color. It is a useful default rendering when the precision of color is not as important as the overall appearance, for example for photographic images. Perceptual rendering relative colorimetric Relative Colorimetric rendering is designed to map out-of-gamut colors to their closest equivalent that is in-gamut, while sacrificing hue, lightness, and saturation as necessary. The effect of relative colorimetric rendering is more precise color rendering for in-gamut colors, as they remain unchanged. However, out-of-gamut colors may incur a heavy penalty in terms of accuracy where Perceptual rendering yields an image that 'looks good' both in terms of hue and saturation, Relative Colorimetric rendering will map the out-of-gamut colors to the closest in-gamut equivalent. Relative Colorimetric renders the 'white' of an image to absolute (paper) white, making the resulting image appear as 'bright' as possible. In this respect, slight changes may occur to the lightness of all colors, as the lightness is 'stretched' or 'compressed' to fit the gamut of the printing material. file:///C|/Documents%20and%20Settings/---/Desktop/HP/html/C000-66.htm (2 of 5) [8/5/2002 2:20:28 PM]
