[And another strange problem: the plates are made with CTP - polymer plates ( Fuji ). Every 5000-1000 sheets I must change the plates because I'm loosing the highlights ! - and this is more visible on the magenta plate. I verified the plates at the beginning- with an iCPlate ( the plates are linearized ) and the rasters are there ; but disappears when printing. Any ideas ?

Hello

I had similar problem with Photopolymer plates as well. Some points which you really need to check :

- Use a temperature strip underneath of plate to define real preheat temperature. It should be measured between 100 - 125 C
- Be sure chemical is fresh, check processor parameters acording to Fuji (speed,temp,brush speed etc.) and readjust brush pressure
- Use gum which suggested by Fuji
- Recheck focus and exposure power. What I know exposure power is around 50 - 70 mj/cm2 for Fuji
- Some fountain solutions can be aggressive on plate surface. Ask your plate provider

If everything is done properly, then plate emission itself has problem. Call service.

Hope it helps
