This article explains the importance and use of the color control technique -- on the basis of colormetrics -- for the complete production line in order to produce economically high-quality multicolor prints. For this purpose, first a short survey on the printing technologies and on prepress is given with special consideration to the digital technique. On this basis, the quality of multicolor prints is explained and specified. The principles of colormetrics are only treated to the extent which is necessary for understanding the color control techniques and their measurement devices. Color control devices and systems, which are used in practice, are indicated. A detailed description is given of a special scanning spectrometer, how it is used in the printing technique and how it has been evaluated for pointing the way for quality measurement and control techniques for graphical products and systems. Special emphasis is put on the fundamental theoretical model for conversion of color values to production control settings. In summary, the colormetrics and color control techniques are presented as fundamental tools and components for the development of `color management systems,' as they are absolutely necessary for the calibration of several devices within the production line and for system integration.
