I'm looking for a method to buff newly engraved rolls
We run coating equipment in the converting business. These are gravure coaters that have coating heads that consist of three rolls, one of which is an engraved cylinder. On many ocassions when we place a new engraved cylinder into the machine we often spend many hours of down time because the cylinder is not buffed correctly. This often causes bleed by of the coating between the cylinder and the doctor blade. Our cure for the problem to this point has been to run the doctor blade against the cylinder wet and let it run until the bleed by problem is relieved.
My questions: Is there a quicker method of buffing the roll, once its' in the machine?
Is there a material that could be used for buffing or de-buring of the cylinder, that won't harm the engraving or the chrome finish?Dick Hovasse

Ask the supplier of the engraving and/or chrome plating to slightly polish the surface of the roll before plating it.Guillermo Marrufo
