PURPOSE:To prevent the clogging of a washing shower and the contamination of a surface of a plate and to prolong the service life of a post-processing soln. in the post-processing stage by bringing a washing water into contact with ceramics to treat a washing water. CONSTITUTION:This device is provided with the insertion part A, developing part B, washing part C, post-processing part D and drying part E for a photosensitive planographic printing plate to be developed. The washing part C consists of a washing water tank 20, ceramic treating tank 21, magnet pump 22, washing water discharge nozzles 6A and 6B and nip transporting rollers 3A and 3B, and the printing plate is transported by the rollers 6A and 6B. Further, the washing water in the tank 20 is passed through the ceramic treating tank 21 by the magnet pump 22, treated and ejected from the nozzles 6A and 6B. The washing water is then cleaned supposedly by the adsorbing and filtering action of the ceramic. |
