Colour image setters, also known as color image setters, are devices used in the printing industry to produce high-quality, full-color images for various printed materials. These devices are capable of creating images with a resolution of up to 2,540 dots per inch, which is much higher than the resolution of traditional printing methods. Colour image setters use a process called phototypesetting to create images. This process involves exposing light-sensitive paper or film to a light source that is controlled by a computer. The computer directs the light source to expose the paper or film in a pattern that corresponds to the desired image. The exposed paper or film is then developed using chemicals to create a negative image of the original. The negative image is then used to create a printing plate, which is used to transfer the image onto paper or other printing material. The printing plate is coated with ink, and the ink is transferred to the paper or material using a printing press. This process is repeated for each color in the image, using a separate printing plate for each color. Colour image setters are widely used in the printing industry for a variety of applications, including magazines, brochures, and packaging materials. They are particularly useful for producing high-quality images that require precise color matching and fine detail.
