Arte SF25 Thermals

Thermal positive offset plate for imaging on CTP platesetter. The coating is sensitive to infrared diode laser
(IR) at 830 nm. For medium-long runs.
More sentitive. Faster. More productive.
More than just a plate

ON PRESS
Apply GUM M-503 ready to use for short period of storage.
Apply GUM F-520 for long terms storage. Hand use.
Apply GUM T-511 ready to use for hardening of the image by baking.
Use gel DELETION GEL POS or DELETION PEN POS with wide and fine point. Apply over the area to be corrected
and wait for 20 - 30 seconds. Remove by washing with abundant quantities of water.
Hardening of the image by baking will increase the press life of the plate.
Before baking apply GUM T-511 for protection of the plate during the process.
Baking conditions: Static oven: 230 ºC during 4 - 5 minutes.
 On-line oven: 255 ºC during 2 - 3 minutes.
PLATE CLEANER A-561 as preparation for the background areas. Avoid systematic use, the solvent base
of the cleaners could damage the image and reduce print capacity.
Fountain solution additives IPAGSA FOUNT PH are suitable for all sheet fed and web presses.
Recommended pH range: 4,8 - 5,2.
Recommended conductivity range: 800 - 1.500 μS/cm.
