Testing the Printing Systems for Enlarging Color Reproduction

The process of manufacturing multicolor printed matter is rather complicated as the components of printing system are diverse by the configuration and have a complex of various properties that in aggregate form production quality. Difficulties in solving the problem of ensuring the quality of a multicolor image are determined with the instability of the properties of printing system components, their diversity, both in physicochemical and structural-mechanical properties. All this causes different divergence of the process parameters and does not allow obtaining a qualitatively stable ready-made product. The results of investigation of the possibilities in enlarging color reproduction of a printing system the "inkjet printer - paper" are presented in the work. The role of paper sheet characteristics is noted. It is shown that the priority belongs to paper with a uniform, microporous surface.
