摘要： PROBLEM TO BE SOLVED: To prevent generation of re-transfer contamination in the process to make re-printing (two-side or multi-color printing) on a printing sheet of paper whose at least one of the surfaces has undergone printing and enhance the operation effectiveness in two-side printing and multi-color printing. SOLUTION: A transcribing member 12 rotates in abutting to the peripheral surfaces of transporting rotors 8, 9, 11a, 11b, 2 to rotate in contacting with that surface of a printing sheet of paper which has undergone printing. Undried ink on this surface of the sheet 3 being transported may transfer to the peripheral surface of the rotor 11a, etc., and the transferred ink is spread thin in the abutting areas of the peripheral surfaces of the rotor 11a and transcribing member 12 so that ink drying is promoted, and part of the ink is transcripted to the peripheral surface of the transcribing member 12. This prevents generation of re-transfer contamination of the partially printed sheet 3. Because two- side printing or multi-color printing can be started before the ink is dried perfectly, the operation effectiveness can be enhanced.

摘要： PROBLEM TO BE SOLVED: To increase the removing capability of excessive emulsion ink on a printed matter to prevent the transference of the emulsion ink, not dried yet, on the printed matter to the other parts of the same. SOLUTION: An ink removing sheet S is formed of a porous layer, for separating the emulsion ink into a pigment and the other constituents, and a retaining layer, for absorbing and retaining a constituent except the pigment, separated in the porous layer, to remove excessive emulsion ink on the printed matter P immediately after printing through the ink removing sheet S. According to this method, the removing capability of excessive emulsion ink on the printed matter P can be increased.

摘要： PROBLEM TO BE SOLVED: To contrive to silence an equipment by reducing the noise at printing pressing by lessening the amounts of motion of a printing pressing member and of a plate cylinder, miniaturize a device, and improve the degree of freedom of a layout on the device by a method wherein the amount of projection of a master locking means beyond the outer peripheral surface of a plate cylinder is reduced and the phases of the master locking means are shifted from each other. SOLUTION: This equipment is equipped with a double-structured master locking means 5 having a locking member 6 made of a comparatively thin plate member having a magnet 9 on the surface 6a opposite to the outer peripheral surface 1A of a plate cylinder 1 and a holding member 7, which holds the locking member 6 movably towards its opening and closing direction towards the outer peripheral surface under the state that the magnet is dropped from the outer direction of the plate cylinder so as to allow to open and close toward the outer peripheral surface. The thinning of the master locking means 5 is contrived and, at the same time, its strength is ensured. The amount of projection of the master locking means 5 beyond the outer peripheral surface 1A is reduced.
