Abstract:
A doctoring cup particularly suited for inking non-flat plates includes a plate contacting edge with an "Ease of Flex" parameter greater than about 0.020 lb-1. Ease of Flex is defined as 1/(Mt2), where t is the thickness of the plate contacting edge and M is the flexural modulus of the material from which the cup wall defining the edge is formed. By non-flat plates is meant plates out of flat by greater than 0.0002 inches/inch.
