Printing rolls having wear indicators and methods for determining wear of printing and anilox rolls and sleeves

摘要

A printing device, system and method are disclosed for measuring and displaying the amount of wear experienced by printing rolls. A wear detection mechanism (25) is employed in connection with rolls, such as anilox-type rolls (22) that transfer ink to a substrate in forming a printed image. A wear detection mechanism is engraved, etched, or the like into the outer circumferential surface of the roll to provide an indication of the amount of wear experienced by the roll. Portions provided in series at predetermined depths may be correlated with a depletion scale indicia to display the wear condition of a particular roll in a printing system. A depletable wear strip comprising multiple engraved portions which correlate with values upon a depletion scale may be employed.
