摘要： PROBLEM TO BE SOLVED: To provide a printing method, with which a scumming-free high quality printing can be executed at a low cost without making a test printing. SOLUTION: This printing method includes a resin and the solvent for the resin and employs an ink including an additive incompatible with the resin and the solvent and no dampening water is necessary. The method also consists of the first process for deciding the adding amount of the additive to the ink based on the tack value of the ink, and the second process for applying the ink including the decided adding amount of the additive onto the surface of a plate, on which images consisting of image parts and non-image parts are formed. Due to the adding amount of the additive is determined by employing the tack value as an index, the adding amount optimum for preventing scumming from developing is easily obtained without making a test printing even under the condition that the kinds of ink and production lots are varied.

摘要： PROBLEM TO BE SOLVED: To solve a problematic point intrinsic to an anti-plate elongation technique due to the heightening of a bonding force between a form plate and a plate cylinder such as the realization of more difficult winding of the form plate about the plate cylinder and a problematic point such as the deterioration of a printing image quality due to the development of the lowering of the bonding force of the form plate to the plate cylinder from the repetition of printing operations by several times and to the resultant insufficient anti-plate elongation. SOLUTION: If a powder layer 5 is employed as a destructive layer 20, when the form plate 1 is pulled, a shearing stress is applied parallel to the powder layer 5, resulting in minutely displacing each powder 4 by skidding and destructing the layer internal structure of the powder layer 5 and realizing very relative splipperiness of the form plate 1 to the plate cylinder 2.
