A color management system—a set of computer programs or utilities that ensure consistent color throughout the prepress processes by calibrating the color relationships among the scanners, monitors, printers, imagesetters, and other devices in the chain from input to output—developed by Agfa. FotoFlow comprises a set of utilities and applications, the most important of which is FotoTune, a program that uses "ColorTags," a series of CIE-based device profiles, to match colors between different devices. In particular, the ColorLinks feature allows the merging of ColorTags to convert from color space to color space quickly and accurately. (See ["Color Management System [CMS]"].)
