RGB stands for Red, Green and Blue, the three colors
your monitor uses to create imagery. All design done for the internet is in RGB color, Adobe Photoshop’s default
color mode is RGB, and some small inkjet printers now claim to print in RGB, so what’s the problem with RGB?
Why shouldn’t you be able to use RGB for your print design?
The truth is that RGB color is a color spectrum that was designed for what a computer or television monitor
can produce, and not what a printer can produce using ink on paper. The monitor on your computer emits colored
light that is RGB color.
CMYK is a color spectrum that is more limited in its color range, yet more realistically mimics what can
be produced by conventional 4-color printing. CMYK stands for Cyan, Magenta, Yellow and Black, the 4 colors
used in conventional offset printing. Most professional design applications have both CMYK and RGB as
color modes to work and save in.
If you get in the habit of working and saving in *CMYK for print jobs, you quickly find that this
ceases to be an issue at all.
* One exception to this rule is “Wide Format Printing”. Our HP 5500 Wide Format inkjet printer
actually matches RGB color better than CMYK. So if you’re printing wide format banners or posters,
save in RGB please.
