renderointitarkoitusten

Renderointitarkoitukset, or rendering intents, describe how colors are mapped when converting color data from one device or color space to another. They govern how out-of-gamut colors are handled and how color relationships are preserved, and they are a central concept in color management used in imaging workflows to predict how colors will appear on different devices.

The main intents defined by the International Color Consortium (ICC) are perceptual, relative colorimetric, absolute colorimetric, and saturation. Perceptual aims to preserve overall color relationships by compressing the source gamut to fit the destination gamut, often producing natural-looking images. Relative colorimetric preserves in-gamut colors exactly and maps out-of-gamut colors to the closest reproducible color, useful when colors outside the destination gamut are not critical. Absolute colorimetric maps colors including the source white to the destination white, used for proofing and exact color comparisons. Saturation prioritizes vivid colors, compressing the gamut to maintain saturation rather than color accuracy, commonly applied to charts and business graphics.

In practical workflows, the user selects an intent during color conversion or soft proofing, and the chosen profile along with device characteristics determines the final appearance. Renderointitarkoitukset are integral to color-managed workflows across imaging, print, and display technologies.
