ABSTRACT:
The doctor portion of the ink cup of a pad printing machine is formed of a polymeric composite which has high compressive strength and high resistance to chemicals, notably to printing inks. The polymeric doctoring portion is tapered and defines a narrow distal end surface which circumscribes the open end of the cup for doctoring engagement with an opposed plastic gravure surface. The doctoring portion may be a separate ring element suitably mounted at the open end of the cup body or it may be a unitary part of the cup. In a preferred embodiment, this doctoring portion is a ring formed of a polymer composite reinforced by carbon fibers and which is permeated by lubricant particles or granules of graphite.
