Definition of colour separation

The term "color separation" originated in the printing industry during the mid-20th century with the advent of color printing technology. The process of reproducing images in color starts with separating them into their primary colors, which are cyan (blue), magenta (red), and yellow. These colors, when printed on top of each other, create a full-color image. Each of the primary colors is separated into a different channel, or layer, during the color separation process. This allows for precise control over the amount of each color that will be used to reproduce the image accurately. Each channel is then printed on a different plate or film, which is used to transfer the image onto the final printing substrate, such as paper or plastic. The technology used for color separation has evolved over time, with the advent of computer-based systems that use digital images and software to divide the color spectrum into smaller intervals called pixels. This process, called digital color separation, allows for greater control and precision in reproducing colors accurately, making it a more efficient and cost-effective solution for modern printing needs. In summary, the term "color separation" refers to the process of separating an image into its individual primary colors in preparation for printing, with the goal of creating a final product with accurate and vibrant colors.
