  • Patent number: 7586656
    Abstract: The invention is a process for producing an optimised printing form comprising printing onto a substrate with a printing form with predetermined raster percentages on the printing press to obtain a test print in form of a stepped wedge with raster patches, measuring the reflectance spectrum of each raster patch, determining associated colorimetric values L*,a*,b* from the reflectance spectrum, transforming the colorimetric values L*,a*,b* for each raster patch in linear correlation with the color perception of the human eye, using the formula RCD = ( L * ? rasterpatch - L * ? substrate ) 2 + ( a * ? rasterpatch - a * ? substrate ) 2 + ( b * ? rasterpatch - b * ? substrate ) 2 ( L * ? solidshade - L * ? substrate ) 2 + ( a * ? solidshade - a * ? substrate ) 2 + ( b * ? solidshade - b * ? substrate ) 2 · 100 ? [ % ] wherein RCD is the relative colorimetric difference expresse
