Title: Waterless planographic direct printing method
Inventor: KITAGAWA TAKAO
IPC: B41M1/08
Filed: 1986-08-22
Abstract: PURPOSE:To ensure favorable spread of an ink in a solid area and enhance image quality of printed matter, by irradiating an inked surface of a printing plate on a plate cylinder with light from a near infrared lamp having a major light emission wavelength region in a specified range, immediately before printing. CONSTITUTION:A near infrared lamp 5 for irradiating an inked surface of a printing plate with light of a specified wavelength at a position on the immediate upstream side of a printing position has a light emission wavelength region of 0.76-3mum. When the inked plate surface is irradiated with the light from the lamp 5, black image areas absorb the light, whereas white non-image areas reflect the light, so that the non-image areas are not heated. The inked plate surface thus heated selectively only in the image areas is brought into contact with a printing paper, followed by pressing by an impression cylinder, whereby direct printing on the printing paper is achieved. An effective light irradiation timing is after inking the plate surface by an inking roll roll and before the contact of the inked plate surface with the printing paper. By this, it is possible to obtain an excellent direct-printed matter with favorable ink spread in solid areas.

Abstract: PURPOSE: To prevent the generation of noises attributed to the turbulence of air current with higher efficiency of equipment by optimizing the flow of air. CONSTITUTION: Upper and lower flaps 61 and 63 are arranged near a diffuser port of an air path 60 and an auxiliary flap 64 on the windward side of the upper and lower flaps 61. In heating operation, a part of hot air flowing on the side of a wall 60A (indicated by the arrow WU) is turned askew downward with the auxiliary flap 64 and then, downward directly with the upper and lower flaps 61. On the other hand, the other part of the hot air flowing on the side of a wall 60B of the air path 60 (indicated by the arrow WL) is turned downward directly with the upper and lower flaps 63. Hence, all of the hot air is discharged downward directly resulting in a higher efficiency.  This eliminates leakage of the hot air between one end 61A of the upper and lower flaps 61 and the wall 60A of the air path 60, eventually causing no vortex of air, a factor of a noise on the room side of the upper and lower flaps 61.
