Moreover, the apparatus further comprises a printing plate cylinder and a printing plate coupled to the printing plate cylinder.
Claims18
An apparatus, comprising:
- a plate cleaner assembly, wherein the plate cleaner assembly further comprises:
- a frame;
- a roller coupled to the frame;
- a dry cleaning material coupled to the roller such that the dry cleaning material passes over the roller, and
- a spray assembly coupled to the plate cleaner assembly;
- a controller coupled to the plate cleaner assembly;
- a printing plate cylinder, and
- a printing plate coupled to the printing plate cylinder
- wherein the controller is configured to:
- determine a width of a spray pattern by the spray assembly;
- determine an amount of time to move the dry cleaning material;
- determine an amount of time to elapse between a wet cleaning and a dry cleaning;
- determining a number of cleaning cycles;
- determine a pressure for a nozzle of the spray assembly to spray solvent;
- and
- determine a pressure for the roller to apply to the printing plate.
