DESIGN TIP… CMYK Versus RGB
RGB – is the color you see on your monitor, made up of Red, Green and Blue. This colors appear more vibrant and pop when viewed on your computer screen.
CMYK – are the colors that are used when printing. They are referred to as “process colors” in the printing industry. CMYK is short for Cyan, Magenta, Yellow and Black.
When designing in Photoshop, Illustrator or Publisher it is important to always create your document in CMYK mode as it will give you a better representation of how it will look when printing
As you know some filters like the render filters are disabled in CMYK mode in Photoshop and Illustrator. Here is a quick tip… work in RGB mode with CMYK preview turned on. CTRL or CMD+Y (CTRL button for PC users and CMD for Mac users) build your file as normal. When you are finished, convert it to CMYK. This will allow all the filters to work, give you a smaller file size to work on and you won’t “lose” your colors when you convert it.
