Glossary Of Color Management Terms Destination Profile Gamut GCR Halftone ICC JPEG Lightness Matte OPI PCS Perceptual Press Emulation Pure The color profile that converts PCS to the output device's color space. In other words, a destination profile can be sent to the printer. The complete range of colors a device can produce. Most printers have unique gamuts compared to other printers. Often, however, the printer can emulate the output of a different printer through use of a Color Space Transformation. Gray Component Replacement: the process of removing the graying component, or dirtying color, from a color and replacing it with black. For example, a red containing 100% magenta, 80% yellow and 20% cyan without GCR might contain 90% magenta, 70% yellow, 10% cyan, and 10% black after GCR has been applied. A pattern of dots of varying sizes applied to an image of varying tones, or same-sized dots applied to a tint of color. Used to reduce moire and other artifacts of the printing process. International Color Consortium An image file format which is in RGB color space. The .jpg files in a print job will need to be converted to CMYK prior to printing. The perceived reflectance of a surface. Matte refers to an attribute of a stock which is a flat color with no glossiness. Matte stocks tend to appear halfway between uncoated stock and coated stock. Open PrePress Interface: the process of substituting fullresolution images residing in a repository for low-resolution images at RIP time. Profile Connection Space. DocuSP employs XYZ as its Profile Connection Space. XYZ is a color space model that maps colors according to human eye response. A rendering intent that maps colors to the nearest hue relative to the white point of the media and compresses the printer's gamut. The intent maps colors relative to each other, allowing more distinction between colors and increased shadow detail. The DocuSP controller can emulate outputs from other types of printers. Examples include SWOP Fogra Matte, Fogra Uncoated, Fogra Coated, Commercial Coated, as well as either iGen3 CMYK or DC 2000/6000 CMYK (depending upon your printer). A rendering intent that warps colors close to a pure colorant (C, M, Y, K, R, G, and B) to the pure colorant. B-2 Color Management Guide
