CTP Thermal Plate
Thermal CtP Plate
BRIDGEHEAD Thermal CTP plate is a positive-working printing plate competible with plater-setters from all the main brands in markte. The plate takes use of the fine aluminum plate with complex grain construction and dense oxidized layer as its substrate. The substrate makes the plate possessing excellent runlength and exact dot reproduction to guarantee high quality printing.

Advantages of CTP Plate
CTP has several advantages over conventional platemaking. In CTP, one generation (transfer of film image to the printing plate) is removed from the printing process (eliminating the need for film and related developer chemicals), increasing sharpness and detail. CTP avoids potential losses in quality that may occur during film processing, including scratches in the film, and variations in the exposure. An imagesetter usually has an accuracy rate of ±2%. Plates are produced in less time, are more consistent, and at a lower cost. CTP can also improve registration and image-to-edge repeatability over traditional methods.
