colour separation process

Color printing is the process of reproducing images in color on a printed page. This is achieved through a technique called color separation, which isolates the components of an image that will be printed in specific colors. The most common method is the four-color process, utilizing cyan, magenta, yellow, and black inks (CMYK).12

In this process, the original material is photographed through color filters. Each filter captures the image's components for one of the four inks, creating separate negatives. These negatives are then used to produce printing plates. When these plates are inked with transparent cyan, magenta, yellow, and black inks and printed in precise registration, they combine to recreate the full spectrum of colors and shades of the original image. This subtractive color mixing allows for a wide range of hues to be produced from these four primary colors.1345
