11-12 Understanding color management systemsColor Reference Guide for C9800 - 12To create successful color documents and presentations, you can take advantage of thefeatures of color management software as they are implemented by the Fiery and onyour desktop computer. This chapter is devoted to various elements of colormanagement that contribute to predictable color results.Understanding color management systemsA color management system (CMS) is a “translator” between the color space ofthe source device (for example, the monitor or a scanner) and the color space of thedestination device (for example, the printer). It compares the color space in which thesource image was created to the color space in which the job will be output, and adjuststhe colors in the document to maintain consistency across different devices. A CMStypically uses a device-independent color space, such as CIELAB, as its intermediatecolor space. To perform its translation, a CMS needs information about the color spaceof the source image and the gamut of the printer. This information is providedthrough profiles, often created by the makers of the computer monitor or printer.The end product of a CMS conversion is a printed document or an image file in thegamut of a particular printer.There has been progress toward standardization in the field of digital colormanagement systems. Both the Windows and Mac OS operating systems support anindustry standard format developed by the International Color Consortium (ICC).This ICC format is implemented on Windows computers as Image Color Matching(ICM) and on Mac OS computers in ColorSync. More and more software developersare also incorporating color management systems into high-end applications.The Fiery color management system, ColorWise, supports this standard profileformat.How color management worksBefore you can print a color document, the color data in it must be converted to thegamut of the printer. Whether performed by the Fiery or a host-based CMS, theprocess of converting color data for a printer is the same: the CMS interprets RGBChapter 1:Overviewof ColorManagementConcepts
