Doctors Do Lots

Loading pressure on the doctor blade is a key variable that impacts printing quality, along with doctor blade and anilox roll life. It is always the objective of the doctor blade system to provide proper ink metering at the lowest possible loading pressure.

Loading pressure is even more of a concern when a printer is dealing with higher line screens. "Higher line screen anilox rolls have resulted in much thinner cell walls which have contributed to the scoring of anilox rolls," says Nick Bruno, president of Harris & Bruno International. "It is imperative that chamber loading pressures be kept to an absolute minimum."
