Digital Printing
CTP plate-setters of the highest productivity in the world.
Computer-to-Plate or “CTP” imaging refers to direct transfer of digital content onto the aluminum plates used in offset printing. This involves exposing meter-scale flexible aluminum substrates to high-intensity, near-infrared laser light in order to thermally modify the surface. High-laser power levels are required: up to 80W on a single GLV® device and power densities of 10kW/cm2.
Resolution and throughput are key attributes for these systems. CTP image content is characterized by binary and halftone (dot) images up to 4000 dpi (6.4 µm features), and SCREEN plate-setters can process up to 70 B1 format plates per hour.
The high-speed, high-power handling, and precise intensity and timing control of the GLV® make it an ideal modulator for this application. SCREEN has been selling the GLV®-based plate-setters since 2003 and has sold more than 5,000 units in total while maintaining the top market share in the world.
