CTP Plate Making Process
There are 6 steps in the Cosmolight® CTP plate making process which are described below. The only equipment that is required is a ‘combi processor’ – a combined washout, exposure & dryer unit such as an Aquasupreme or Cosmoline and a laser ablation device for imaging the flexo-digital-plate.
1. Back exposure
Expose the back of the plate with UV-A for setting the floor thickness in combi processor
2. Laser Ablation
In imaging device such as Esko CDI or Xeikon Thermoflexx
3. Main Exposure
UV-A exposure in combi processor
4. Washout
Process the plate in combi processor
5. Drying
Heated air dryer in combi processor
6. Post-exposure
Expose to UV-A and UV-C light again to complete photo curing in a combi processor and to eliminate the tackiness of the plate surface
Toyobo Cosmolight® CTP plates are revolutionary water-washable digital flexo plates that are durable to water-, solvent- and UV based ink. Toyobo Cosmolight® CTP plates can be used in all CTP imaging devices and are available in 3 versions:
