 Re: Full Color, 4 Color, 6 Color, Seps, halftones oh my!
process printing is really tough. There are tons of colors that are impossible to achieve with cmyk. Red and grays are big ones as mentioned grays look more blue. In order to achieve these colors you either need to run hex seps or add spot bump plates to get those colors. Your software should have an out of color gamut view to show you the areas of the image that will be hard if impossible to achieve with cmyk. This is one reason simulated process came about. You also get a more vibrant and accurate print as your using specific colors in the design rather than using 4 to create all the colors
Impressions magazine has had numerous articles on this process. You might search their site for past articles or even get reprints. |
