METHOD FOR ADAPTING A PRINTING PROCESS WITH MAINTENANCE OF THE BLACK STRUCTURE

A method of producing a color space transformation, with which the color values of a first printing process can be converted into the color values of a second printing process so that the black build-up of the first printing process is substantially transferred into the second printing process and t...

Zusammenfassung:A method of producing a color space transformation, with which the color values of a first printing process can be converted into the color values of a second printing process so that the black build-up of the first printing process is substantially transferred into the second printing process and the visual impression of the printed colors in the two printing processes is substantially the same, includes characterizing the color reproduction characteristics of the printing processes by color profiles, which specify an association between the device dependent color values of the printing processes and the color values of a device independent color space. From the color profiles, lightness curves are determined as a function of the black printing ink and color curves are determined as a function of the non-black printing inks and linked to form the color space transformation sought.
