Offset Printing Plate

Offset Printing Plate Thermal CTP Plate STP-II STP-II is based on STP-I ,and is enhanced on the anti-solvent characteristic .So STP-II can be suitable to not only conventional printing, but also UV-ink printing without being baked. STP-II specification:Type: positive thermal CTP plateSpectral sensitivity:830nmExposure energy:120-140mj/cm2 Developing time: 20-40 seconds ( STRONG developing liquid or koda Goldstar preminum liquid, 23±2 degrees centigrade) Resolution:200 lpi (1-99%) Run-length: 100,000 -- 500,000 (varies with its printing conditions and imaging content) Safelight: Yellow light, or fluorescent lamp with UV filter film Advantages: 1. resist UV-ink 2. High sensitivity 3. wide developing tolerance4. good stabilization on anti-aging.5. can be operated in daylight room.
