CTP Thermal plate is a special printing plate for thermal CTP plate setter. Controlled by computer, it is directly scanned by a 830nm laser and after suitably processed, placed on press for printing. CTP Thermal plate frees people from conventional printing films and related film making procedures. It shortens time for making plate and minimizes mistake chance by guaranteeing image exact reproduction.

Matters Need Attention for CTP Thermal Plates | |
1. CTP Thermal plates get scratched more easily than traditional ps plates, and therefore should be handled gently with care to avoid striking, folding or falling.
2. CTP Thermal plates should be unpacked in yellow light or room light; the recommended plate-making room light is also yellow. Correct parameters must be set, developer should be replaced in time. |
