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.sup.-1. Ease of Flex is defined as 1/(Mt.sup.2), 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. The doctoring cup can be used to ink both flat and non-flat printing plates using a doctoring pressure of less than about 300 psi.
