Abstract
The apparatus for coating a lithographic printing plate or a photosensitive material (M) with a processing liquid comprises first and second pairs of feed rollers (41,42: 44,45) for feeding the photosensitive arterial along a predetermined path. A coating roller (125) is provided therebetween. Guide members (48, 49) contact the bottom surface of the photosensitive material and to guide the photosensitive material. The contacts of the guide members and the photosensitive material are at the levels higher than the coating level at which the processing liquid is applied to the photosensitive material to prevent uneven coating of the photosensitive material with the processing liquid after the trailing edge of the photosensitive material has passed the first pairs of the feed rollers (41,42).
