Glossary Of Color Management Terms Relative Colorimetric Rendering Intent RGB Saturation Source Profile Spectrophotometer Spot Color sRGB SWOP TIFF A rendering intent that maps colors to the nearest hue relative to the white point of the media. The gamut mapping strategy will clip out-of-gamut colors to the gamut boundary. As part of the Profile Color Conversion in the Profile Connection Space, rendering intents can be applied to the job to achieve specific results. The DocuSP controller provides 5 rendering intents: • Absolute Colorimetric • Relative Colorimetric • Perceptual • Saturation • Pure A color space model that defines the relative amounts of Red, Green, and Blue light in the image. The RGB color space is generally seen as an input profile; the printer will need to convert RGB to CMYK in order to print the job. A rendering intent that maps RGB CMYK to CMYK. The G is the printer's G, the B is the printer's B, and the R is a saturated Red. The color profile with which the job was created at the client workstation prior to submission. It is often embedded as part of the PDL, but if not embedded, a source profile can be assigned by the DocuSP controller at the job or queue level. A tool which measures the quality of the printed test pattern and enables calibration of the printer. This is accomplished by measuring the spectral wavelength of light reflected from a substrate (surface). Spot colors are selected from books or charts that contain printed color samples, each of which is identified by some number. Usually, the numbered colors are also described in the CMYK system. One widely used numbering scheme is known as the PANTONE® Matching System, or PMS. The DocuSP controller contains a spot color editor that provides PANTONE® Coated and Uncoated color definitions. Standard (device-independent) RGB. Standard Web Offset Press. A type of printing press for which the DocuSP controller provides an emulation. Tagged Image File Format. Color Management Guide B-3
