摘要：The object of research is the account of the peculiarities of color rendering in the process of publication preprint preparation. One of the most problematic places is manual color management, which is often done empirically, using simple tests and errors, which adversely affects the quality of the product.Methods of analysis and synthesis are used in research. The characteristic features of color are determined in terms of the work of the prepress engineer. It is found out that the main points which always need to be taken into account when conducting preprinting are the regime of consistent rendering of paint and the printing mode overlay.The technology of mixed color management is proposed.The result of the implementation of this technology ie the following recommendations:– for the creation of gradient fills and other similar effects with the transition in white as the final value of white, the initial mixed color with the value Tint=0%;– to create gradient fills and other similar effects with the transition in transparent it is more reliable to apply the transition mode in white with the installation of the printing attribute with the overlay;– to create complex interactions between triads and blends should be used combinations of objects using the overprinting attribute.An algorithm for recording the characteristics of color rendering is created. As a result, the main contradictions concerning the use of color are resolved, and the methodical recommendations for the support of the prepress engineer are received taking into account the correct color reproduction. Automation of the process of determining the parameters of trapping is carried out. This automation gives the prepress engineer the following capabilities:– creation of a database, operational information files for color rendering;– obtaining recommendations for the analysis of individual objects at different stages of work;– further use of the information support system as a guide.This provides an active tool for maintaining prepress processes and getting some effects from the introduction into production. In particular, the productivity of the technological process of prepress preparation and its cost reduction may be increased.
