Optical comparison of reproduction in the closed graphic systems

Modernization of the graphic production caused the appearance of different input and output units in the systems of graphic reproduction. Each of them has the same goal to obtain the reproduction true to original reproduction. Different proofing systems are used today for quality control and they play important role in communication between the client and the printer. They are used mostly as a kind of "contract" by which the ordering party accepts and permits the printing of products. From these reasons color management in each particular system as well as its standardizing is necessary.
