Estimating the term…
A printing device, system and method are disclosed for measuring and displaying the amount of wear experienced by printing rolls. A wear detection mechanism is employed in connection with rolls, such as anilox-type rolls 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.
A printing roll for applying colorant to a substrate, said printing roll having a plurality of colorant transferring cells, said roll further having an outer circumferential surface, said colorant transferring cells having a depth defined beneath said outer circumferential surface, said roll having a wear indicator mechanism about said outer surface, said wear indicator mechanism comprising at least one indicator cell having a predetermined depth relative to said depth of said colorant transferring cells, whereby wear of said indicator cell indicates the degree of wear of said colorant transferring cells, wherein said wear indicator mechanism is outside of the area defined by said colorant transferring cells.
A system for determining the amount of wear experienced by a cylindrical roll, said roll being held in contact with a doctor blade, said roll being positioned to receive colorant from a reservoir and transfer the colorant to a substrate, the system comprising:
A method for detecting in a printing system the amount of wear experienced by a cylindrical roll, the method comprising:
