NOTE: Be aware that it is possible to see colors in RGB that you can’t make with CMYK.
They are said to be “out of the CMYK color gamut”. What happens is that the RGB-to-CMYK translator just gets as close as possible to the appearance of the original and that’s as good as it can be. It’s something that everyone in the industry puts up with. So it’s best to select any colors you use for fonts or other design elements in your layout using CMYK definitions instead of RGB.
NOTE: The following programs do not have the capability to convert to CMYK.
