rendering intent Relative colorimetric rendering absolute colorimetric Absolute Colorimetric rendering behaves the same as Relative Colorimetric rendering except that no compression or stretching of the lightness occurs to fit the gamut of the printing material. If the source image contains colors that are lighter than the printing material, they will be clipped to the color of the printing material. If the source image's white is darker than the printing material, it will be printed with some ink in order to simulate the input white as precisely as possible. This means that the whitest 'white' mapped by the absolute method is the white of the printing material measured when the profile was made. Proofing for printing processes that use non-white printing materials (like newsprint) is more effective with Absolute Colorimetric rendering because the measured paper white is the 'whitest' color rendered in the resulting image. The resulting proof is more representative of the actual printed product than any of the other rendering intents. It is the most effective rendering intent for spot colors, as long as they are within the printing material's gamut. Due to the potential for clipping or printing image white, Relative colorimetric is preferred over Absolute colorimetric for comparable input and output white points. file:///C|/Documents%20and%20Settings/---/Desktop/HP/html/C000-66.htm (3 of 5) [8/5/2002 2:20:28 PM]
