The use of visual information processing program tools for various printing conditionsThe article is devoted to the problem of the transition to the color space of printing synthesis using
the intermediate space of the mathematical evaluation of color to obtain high-quality color reproduction
on various materials. The relevance of the article is caused by insufficient knowledge of the issues
related to the transition from the additive system of color coordinates to subtractive when Pantone colors
are substituted by CMYK. The purpose of this work is to identify a possibility of using the intermediate
space of mathematical color estimation when Pantone colors are substituted by CMYK and
reproduction on various materials. The objects of research are prepress processes. The subjects of the
study are the methods for color evaluating and choose of the optimal correction for reproduction of
an image without distortion of colors. The research problem is that the standard profile is a correspondence
of color coordinates specified in tabular form, which are not enough to achieve color reproduction
on reproductions without distortion. Additionally, when printing on various materials, it is necessary
to take into account its’ characteristics in order to be able to create a profile of the printing press.
When switching from one color space to another, additional processing is possible aimed at changing
the color coordinates. The authors substantiated the conclusion that in order to print Pantone colors
as a standard triad, it is necessary to determine the occurrence of color into the color gamut of the
printing press and perform an additional processing for the quality color transition. The scientific novelty
of the study shows the ability to print these Pantone colors with CMYK colors on various materials
with the necessary physiological accuracy of reproduction. To achieve the acceptable value of the
color difference in the reproduction, the use of selective correction methods is necessary. Thus, it is
necessary, along with traditional methods, the authors propose to develop models, methods and means
of additional processing using the capabilities of software as a combination of methods of transition
from one color space to another.
