Abstract: A variable lithographic cleaning apparatus, system and method works on the principle that dust and ink residue may be transferred from a lower surface energy reimageable conformable blanket surface to a higher surface energy surface low durometer cleaning member, such as the tacky roller, and then to an even higher surface energy cleaning member, such as the hard roller, which is hard and robust to scratching. The hard roller can then been scrubbed clean by an ink flushing device having a third cleaning member, such as a melamine sponge, wetted with a cleaning solution with the hard roller dried upon each rotation.

Abstract: A chamber blade system maximizes ink flow at an anilox doctor blade by including a heating element adjacent the doctor blade to heat ink adjacent the blade. The heating element may be a heat strip next to an anilox doctor blade that heats the ink adjacent the doctor blade and temporarily reduces the ink viscosity to improve the flow of ink in the vicinity of the blade. Doctoring blades with a ceramic tip coating may be configured to allow a small amount of controlled ink flow through that can wet the lands thereby reducing the hydrodynamic back pressures and friction when trying to force the ink into anilox cells.
