CTP Plate Specs and Storage information

Plate run lengths.

This is very dependant on the press settings ( eg roller and blanket pressures ) as well as the type of inks and stocks that are used.
Inks that are high in pigments can damage a plate more, and paper that is high in acid content or high in paper dust can also reduce the run length.
UV inks are harsher on plates than oil inks, but the Fuji LP-NV violet CTP plates have performed extremely well in the UV environment.

Plate Storage

After printing, clean the plate thoroughly with a mild plate cleaner.
Buff the plate dry and apply a ph neutral gum ( eg Fuji GU-7 ) to the plate. Spread it evenly and buff the plate dry. Place a sheet of ph neutral paper on the surface of the plate. The original plate interleaf paper is ideal. Keep the plate flat and store the plate in a cool, dry place. Keep the plates away from strong, direct lights and high humidity.

Tips for plate usage

  • Store plates out of strong, direct lights.
  • Store with a ph neutral gum.
  • Store and handle plates in a low humidity environment.
  • Use mild plate cleaners. Harsh plate cleaners easily remove dry ink.\, but can damage a plate.
  • Clean the ink and other press chemicals off the plate as soon as possible after printing.
  • Don’t bend the plates unnecessarily
