Many of our customers have a hard time understanding why we cannot print in RGB. In most cases, our print ready templates will automatically convert files from the RGB color mode to the CMYK color mode, and more times than not, the conversion is minimal. However, for photographers and artists who rely on their colors to be correct, we strongly urge sending us your file already converted in the CMYK color mode. Furthermore, Printkeg does not color match, however, we will always try to get customer art as close as possible, and we can work with color profiles. Converting or designing your files to CMYK will alleviate any confusion of color accuracy.
RBG and CMYK are opposites since one is a subtractive color and the other is an additive color. The key point is that since viewing files on-screen is RGB, you have to convert to CMYK to print.
Overall, when printing, you should ALWAYS start designing in CMYK. If that is not an option, please convert your file to CMYK. By doing this before you submit your file over to us or any other commercial printer, you can sleep easy knowing your colors will come out on point. There is nothing worse than creating a beautiful sunset drawing in Illustrator, for example, only to have the printed piece come delivered to your door with dull and muted yellows, greens and blues.
When in doubt, call us! We are happy to help make both of our lives easier. The above infographic is an extremely useful way to easily undertand and visulalize the difference between RGB and CMYK and the ramifications of the conversion process.
