Impact of the technology of minimize the total number of inks to the optical parameters stability of imprint at offset printing. — 2012. — № 3(37). — pp. 47–54.
     The influence of the color separation technology on offset printing quality were considered. Analysis of control charts by Shugart revealed that stable optical properties on the print modes provided separations technology GCR Medium and UCR, which is also confirmed by a sufficient level of solid ink’s density ( = 1,3 and  = 1,75). Analysis of the distribution of values of printing contrast and its value within the print suggests that for uncoated paper and paperboard type chrome-ersatz best contrast achieved with the use of technology UCR and GCR Medium. Thus, a wide range of printing materials may be regulated by the application of color modes UCR and GCR Medium. Also, modes of printing process in this case is more manageable projected to secure printing process for any printing presses.
