Here’s a little bit advice for designing print pieces. For years (a decade or more) adobe has included expanded CMYK color gamuts into their design software. However, they have always defaulted your working space to a color space that dates back to the 70’s and 80’s, and was used for web presses.
This color space is called Swop, and if you check your working color space after reading this, you’ll most likely find this relic color space in play.
Gracol, is a far superior CMYK color space, and the standard output profile for nearly every digital press on the market. However, submitting your work in a smaller, limited gamut, will never allow you achieve this extra pop in color. Switch to Gracol, and milk CYMK for as much as it can offer, and in most cases, eliminate a color conversion in the process.
I have tons of tips for color management on the design end of things (and even more for print). I’ll do my best to post more. And feel free to shoot over questions. And welcome, to most controversial topic in print!
