The disadvantage of this model is the narrowness of the color gamut many shades of color with high saturation toxicacid cannot be reproduced using modern process paints. This forces engineers to look for other ways to expand the color gamut such as sixcolor HexaChrom color separations. In this model in addition to the main Cyan Magenta Yellow and Black additional Green and Orange are used. CIE CIE color separation Experienced operators may prefer to convert the image to the CMYK model colour separation immediately before the output of photoforms and to CMYK to carry out the final finetuning of the image.

For example it is convenient to change the e-commerce photo editing contrast in the Cyan and Black channels to remove unwanted contaminants on a human face and conversely to emphasize the shadows. Here we can say a few words about setting the color separation parameters. If youve been using PhotoShop for more than a day youll probably prefer Builtin settings. They are also more familiar to oldschool specialists here you can set all the necessary parameters and the program will work exactly as expected of it. And this is the most important thing in the art of color separation. I will not describe in detail all the settings in this case they reflect my personal preferences but I will dwell on some parameters.



Setting color separation options Setting color separation options Setting color separation options Inks for domestic offset are now mainly used in Europe and this is called Eurostandard in the program. Coated  indicates that coated paper should be used. If your work will be printed on uncoated paper for example newsprint then you need to change the settings to Newsprint or Uncoated before color separation translation to CMYK. The next important parameter is dot gain Dot Gain. This is an undesirable increase in the density percentage of colors under the influence of their absorption into the paper and as a result the physical and optical increase in raster elements.
