How is GLV technology used in CTP print systems?

When used with a high power laser source, the GLV device acts as a very high-speed spatial light modulator – capable of writing several hundred spots simultaneously onto an offset printing surface. The advantage of this approach is that several hundred channels of information can be written to the printing plate simultaneously, instead of creating one “spot” at a time. The GLV device not only features hundreds of precisely-controllable elements, but also switches light very rapidly – enabling better, faster and cheaper computer-to-plate (CTP) solutions.
