GLOBALWARE SOLUTIONS - Shining Light on CTP

GlobalWare's Jack Cote checks the operation of the UV Setter 1116, one of three basysPrint computer-to-conventional-plate systems used by the company. The platesetters have a flatbed design and expose conventional plates using UV light.

The platesetters use an imaging technology the manufacturer calls Digital Screen Imaging (DSI). The heart of the system is a micro-mirror chip developed by Texas Instruments. The surface of this 2x2cm chip is covered with nearly 800,000 individually controllable mirrors that are about one-fifth the thickness of a human hair.
