发明名称 METHOD FOR DEVELOPING PLANOGRAPHIC FORM PLATE WITHOUT USING WATER
摘要 PURPOSE:To improve dot shape of the planographic form plate by imposing a brush roller so as to slant against the carrier direction, followed by developing it. CONSTITUTION:The printing original plate 1 effected an image exposure processing is inserted to a developing machine body 3 from a platen 2 for carrying in, followed by discharging to the platen 4 for carrying out after processing. The developer is supplied on a printing original plate 1 in the developing machine 3 by a pump 6 followed by spraying it by a spray nozzle 7. The developer swells a silicone gum layer, or weakens sticking force between the silicone gum layer of printing elements and the layer existing beneath thereof, thereby making easy to remove the silicone layer of the printing elements as well as to wash out the removed silicone gun pieces from the printing original plate 1. And then, the printing original plate 1 is rubbed with a brush roller 8, whereby the silicone gum layer of the printing elements are removed. By imposing the brush roller 8 so as to slant against the carrying out direc tion of the printing original plate 1, the effect due to an unevenness of the brush 8 is omitted, without shaking the brush 8, thereby obtaining even dot which does not remain the silicone gum layer.
