RGB vs CMYK
In order to be successful in owning a SignWorld business one of the key areas you must have knowledge in is printing. Diving deeper, one of the most important elements of printing is of course, color. Without proper coloring, the signs you print will be boring, and unattractive – they won’t really “pop”. Because sometimes the color looks different on the computer screen than it does when you go to print it, there are different types of color modes when it comes to designing signage. The job of these color modes is to tell the computer which exact colors to print, try to think of them as a separate language made for certain situations, that are all trying to explain the same thing. Two of the most frequently used ones are called RGB and CMYK. We are going to go over them, but first we must talk a little about how as humans, our eyes see color. Upon studying light, Sir Isaac Newton discovered that color is not a natural property in any given object. Let’s take the grass for example, the color green is not actually part of the grass. What is happening here, is that the surface of the grass is merely reflecting the light wavelengths that we see as green and then absorbing the rest. The green light wavelengths then travel into our eyes and are collected by the rods and cones in the back of our eyes. These rods and cones determine what we see. The cones let us see color, and the rods establish weather something is black or white.
