The Argyll color management system supports accurate ICC profile creation f or scanners, CMYK printers, film recorders and calibration and profiling of displays. Spectral sample data is supported, allowing a selection of illuminants obse rver types, and paper fluorescent whitener additive compensation. Profiles can a lso incorporate source specific gamut mappings for perceptual and saturation intents. Gamut mapping and profile linking uses the CIECAM02 appearance mod el, a unique gamut mapping algorithm, and a wide selection of rendering intents . It also includes code for the fastest portable 8 bit raster color conversion engine available anywhere, as well as support for fast, fully accurate 16 b it conversion. Device color gamuts can also be viewed and compared using a VRML viewer.
