Positive PS Plate

SP-1 positive PS plate SP-1 positive PS plate is of distinct dot, high resolution, quick ink-water equilibrium, long press life and a wide tolerance in developing and so on. Whether in conventional dampening system or alcohol dampening system. It can product a clear and delicate press. SP-1 specification: Type: Conventional-positive PS plate Spectral sensitivity:320-450nm Exposure time: 30 seconds;about 20 pulses ( 3000w Iodine-Gallium lamp, from 1m, UGRA PCW82 control strip, the third section un-inking ) Notice: Exposure time varies with the developing conditions and the requirements of different printing materials. Developing time: 20-40 seconds (STRONG developing solution: water=1:7, 23± Resolution: 2-98% Run-length: 50,000 100,000 (varies with its printing conditions and imaging content ) Safelight: Yellow light Advantages: 1. High Sensitivity 2. A wide tolerance in developing conditon. 3. A wide tolerance in operating condition 4. Unique Hydrophilic layer treatment, good ink-water equilibrium 5. Excellent air eduction layer, good dot-reproduction has been assessed and registered as meeting the requirement of GB/TI9001-2000/ISO9001:2000.
