Required energy: 120-130 mj/cm2
Image reproduction: 1-99 % at 250 lines per inch and FM screeningDevelopment
Use developer Revelith-CTP at 23oC ± 1ºC
Compatible with most of the thermal plate developers on the market
Development time: 30 seconds ± 5 seconds
Replenishment: with the same developer at 120-140 ml/m2Gumming
Use Gomalux-LP
When hardened by baking, apply Quemagum-LPDeletion
Use deletion pens Dualpoint-LPBaking
Hardening the coating by baking enables very long runs, over 500.000 impressions, depending on press conditions.
Apply Quemagum-LP
Baking conditions: Static oven: 200-230°C during 5-6 minutes
On-line oven: 230-250°C during 3-4 minutes
