Title: Study on Color Simulating between Offset Printing and Digital Printing
Abstract: Color output capability and output accuracy of digital printing machine used for simulating the offset press were analyzed.A digital machine,Hplndigo 1050,was used in this study.The colorimetric values of its primary colors-cyan,magenta,yellow and black were not the same as that used in the offset press,and the differences between them could not be removed by adjusting the maximal output ink level.The HpIndigo's color gamut,consequently,could not completely meet the offset print requirement,typically presenting the absence of some colors equal to and close to the most chromatic offset's colors.So color management technique was used in our experiment,and the offset's CMYK values were translated into the digital machine's CMYK values with the relative intent color simulation through these two machine's profiles.The results showed that the color output accuracy within the offset color gamut was raised on the whole,and the big color differences only happened on these colors outside the digital machine's gamut.Numerically,for 928 colors in IT8.7/3 chart,the CIELAB average/maximal color differences decreased form 4.98/13.90 to 3.13/13.13,respectively corresponding to the cases before and after color management.Specially,for gray colors,the average/maximal color differences changed form 4.91/5.59 to 0.92/2.00,improving the gray reproduction dramatically.
