Abstract (en)
[origin: JPH0485039A] PURPOSE: To reduce a friction between a plate cylinder and a printing plate by disposing at least two films having different slip frictional coefficients between the cylinder and the plate. CONSTITUTION: A surface 2 of the plate cylinder 1 has a specified roughness. A printing plate 3 is pressed on the intrinsic cylinder 1, and its lower side has a specific surface 4. A lower surface 7 of a lower film 5 has larger roughness than that of an upper surface 8, and an upper surface of the film 6 has correspondingly a larger roughness than the lower surface 10. In other words, sides 8, 10 in contact with the opposed films 5, 6 are satisfactorily smooth, while the opposite sides 7, 9 have recognizably large roughness. The surfaces 2, 4 also have considerable roughness. In an operation, layers are brought into contact with each other. The plate 3 having the upper film 6 can be relatively easily moved to the cylinder 1 having the lower film 5 in close contact.
