摘要
A method of producing a pitted roll for an offset litho press inking unit, more especially as part of a short inking unit, comprising the application of a dual coating layer of which the inner layer is formed of a material such as copper with a high affinity for ink and the outer layer is formed of ceramic material to give lands wiped by a doctor, preferably set at a negative angle, around the pits. A high wear resistance and a high accuracy may be achieved if the plain base member of the roll is coated with copper or the like and then with ceramic material, after which engraving takes place to penetrate the ceramic layer right into the copper or the like material with an affinity for ink.
