The problem of complex evaluation of quality reprints has been examined in the article. According to the analysis conducted, the basic parameters of the prints offset sheet quality, such as optical density, dot gain, excretory capacity, accuracy of color combination, gray balance have been set. In accordance with the terms «low», «satisfactory», «high», the fuzzy logic basic parameters of quality prints with performance conditions «if-then» have been formed. Based on this knowledge base there have been built fuzzy logical equations to calculate the options for quality imprints, and the difuzzyfication of the «center of gravity», allowing to obtain a quantitative indication of the quality of imprints, as a result of observance of the appropriate mode of the printing process, has been conducted.

Keywords: quality of imprints, linguistic variable, knowledge base, fuzzy logic.
