In order to get the most out of your print marketing materials, or really any kind of printing needs you have, it's a good idea to know what's processes are use to create your marketing materials.
Full color printing has become popular nowadays. With today’s technology it's sometimes impossible to tell which photos are the original and which were printed copy. Survey has shown that the use of color increases the rate of reading and retention in advertising and various publications. The most important two types of common color model basically you have to know about: the RGB color model and the CMYK color model. We'll also touch on an up-and-coming model: the six-color model.
RGB Color
White light contains all the wavelengths of visible light and has three primary colors. RGB are referred to red, green and blue. RGB colors are known as additive primaries because the lights of these colors produce white light when they are combined. You can combine the RGB colors in various ways: more red and blue with less green equals purple; more red and green with less blue equals purple; for example. These combination of colors are the idea behind full color.
Humans basically see color in three layers, and the eyes combine these layers to give our brain the colors we perceive.
CMYK Color
CMYK color model works totally opposite from RGB color model, in that instead of additive colors, this color model works on the principle of subtractive colors, because the inks subtract brightness from white. In RGB, white is created from combining all the colors, and black is the absence of color. In CMYK, it's the opposite - black is the created from combining colors and white is the absence of color.
This is the most common type of printing most printers use and it's typically known as four-color printing. The four ink colors used to create a spectrum of colors are cyan, magenta, yellow and black. A mistake that is often made when submitting artwork to printers is not converting the images to the CMYK color space. This conversion is needed so that a separate printing plate can be made for each color. For more info on color space, check out http://en.wikipedia.org/wiki/Color_space.
