Development of method of objective control of color reproduction for the offset printing. — 2010. — № 4(30). — pp. 46—50.
     This article illustrates an approach used for control over color reproduction, which is based on the measurement of Lab color coordinates of proofing bar of a print sheet using spectrophotometer and calculation of color difference ?Е, as well as dot-gain. Calculated results are being compared to parameters, recommended by ISO 12647-2 and used for decision making with respect to the quality of color reproduction of a print sheet. This approach can be used for unbiased decision making with respect to the quality of color reproduction, automation of operational controls and making supported adjustments to the technological process, if these parameters substantially deviate from the norms.
