The Theory of the Density-based Gravure Spot-color Matching
Spot-color is widely used in modern package printing technology.In order to use of computer techniques in calculation the formula of spot-color,an algorithm of formula calculation for the gravure spot-color was proposed in this paper.Firstly,the spot-color was divided into ten color areas based on the theory of Munsell color system,and in IGT gravure testing system,the color proofs were printed for each color area,according to different ratio of the cyan,magenta,yellow and white ink,in order to gain the data of mathematics modeling.Then,the algorithm of matching spot-color based on Masking Equation was provided,after measuring and analyzing of the proofs.Moreover,the results of experiment in blue color area show that the algorithm,which was proposed,has good accuracy of matching spot-color.Finally,using the C++ programming language and MySQL database,the prototype computer aided gravure spot-color matching system was developed,the results of operation show that the software is available.
