RGB vs. CMYK

The Difference between RGB and CMYK and why it's important for print

The Difference between RGB and CMYK, and why it’s important for print:
In order to understand the difference between RGB and CMYK, we have to have a basic understanding of each one individually.

RGB (color model) – is an additive color model where red, green and blue light are added together in numerous ways in order to create various colors. The easiest way to understand this is to think of paint or coloring.

CMYK (color model) – is a subtractive color model used in printing and refers to the 4 inks that are used: cyan, magenta, yellow, and key. So, CMY should not be thought of as actual colors but films of ink that filter light to produce different colors. Key is what is added to make the blackest black. It works by either partially or completely masking colors that are typically on a white or light background. Basically, the ink restricts the light that would have otherwise be reflected.

So RGB is best used with things that produce light such as television screens, computer monitors, cell phone displays. The printing color pallet (CMYK) is best used for printed materials.

So, when designing anything for print- i.e. business cards, banners, decals, and brochures; it is best to start the design process with CMYK. If you start the design process in RGB then convert to CYMK the differences can be quite large. See image detail above. So, to ensure you are getting the colors you want with the design you are doing start in CMYK.
