Imagesetter

A device that uses laser light to expose film at high dpi resolution, usually 1200 dpi or higher. Most imagesetters have a maximum dpi of 4000. When generating screens or dots for halftones, each dot is created from the smaller dots that are determined by the dpi resolution. Imagesetters come in many different sizes and formats. They can image one page at a time or they can be manufactured large enough to make imposed film for presses.
