Thermal Positve Offset CTP Plate - CPT-1

• Easy exposure and procesing.
• Compatible with most of the thermal plates and developers available on the market.
• Maximun resolution for the reproduction of stochastic screens
• Fast ink-water balance.
• Enhanced constrast and stability.
• Runs more than 100.000 impresions without baking.
• Cost-efective. CTP-A plate meets user's needs and optimize the printing perfomance.

Exposure / Coating
Coating colour: blue intense
Contrast after development: very high
Day light sensitivity: up to 2 hours exposure does not affect the plate

Compatible with most of the thermal platesetters: Creo, Heidelberg, Screen, Lüscher, etc...
Required energy: 120-130 mj/cm2
Image reproduction: 1-99 % at 250 lines per inch and FM screening

Development
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/m2

Gumming
Use Gomalux-LP
When hardened by baking, apply Quemagum-LP

Deletion
Use deletion pens Dualpoint-LP

Baking
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
