The reality of the situation is that we can only print dots. In newspaper images, for example, you can see this effect is real, sometimes with the naked eye. You’ll see right away if you inspect a printed object with a magnifying lens that what appears to be a single picture is made up of a series of smaller ones. On to the second process, generating Halftones to simulate the colors. In screen printing, each color must be isolated and printed onto a film, then burned into a screen before it is eventually printed onto a garment with ink. This way, the portion of the image with a specific color is printed out separately. Isolating the colors simply means separating different colors in an image.
Separating the colors for screen printing involves two major processes: isolating the colors and generating Halftones to simulate the colors after separating them. Or, perhaps more commonly in screen printing, they are separated by any variation in colors such as pink, red, light blue, dark blue, etc. The components in the files may be printed in four colors: cyan, magenta, yellow, and black, abbreviated as CMYK. Color separation software breaks down images into the constituent parts required to duplicate an image. The general purpose of the color separation process is to prepare the art file so that a film positive may be printed properly. What is Color Separation Software, and Why is it Used?
