な微少な画像欠陥も見られなかった。Non-image area photoconductor layer removal liquid (eluent) Konica Corporation positive-type PS plate developer 5DR-1 Example 1 In the plate making machine shown in Fig. 1, the dust removal section 2 is used for an original plate for electrophotographic printing. At an angle of 50° with respect to the plate surface, 25°030% air is drawn horizontally in a straight line from the edge of the printing original plate on the IO side of the corona charger.
A slit-shaped air nozzle 6 was attached so as to hit the air at a wind speed of 0 to 15+i/see. Further, the supply layer 1b of the printing original plate is closed, and an air outlet (not shown) is provided behind the exposure section 4 so that the air ejected from the air nozzle 6 is circulated from the air nozzle 6 to the charging section 3 and the exposure section 4. I made it. While maintaining this state, 50 plates were made continuously, and 12 of the manuscripts were made.
When we measured the reproduction state of the 5 lines/inch, 50% halftone image on the printing plate, it was within the range of 50 ± 0.5%, or there was slight variation that was thought to be caused by stiffness or dust. No image defects were observed.
