Abstract
A graphic system for producing printed images. The signals representing the image are produced as CMY (cyan, magenta, yellow) printing color component signals and transformed to RGB (red, green, blue) signals for display on a monitor. The transformation circuit is a matrix of arithmetic circuits including look-up tables. The system can also be conditioned so that RGB signals are first produced and these transformed to CMY.
