Abstract
PURPOSE: To prepare a plate material for printing which is excellent in rust-resisting property, close adhesion to photosensitive material and humidity insulation by applying the permeable film surface treatment to the surface of the material of metal other than Al and thereby forming diffusive cracks, orifices and the like.
CONSTITUTION: After grease is removed 21 from the surface of a plate of metal other than Al, especially of an iron plate 20, the plate is immersed in a diffusive layer producing liquid whose main ingredients are a Cr-system polymetal complex compound and electrolyzed for the permeable film surface treatment 22 under the conditions of DC voltage 5W15V, current density 5W15A/dm2, the temperature of liquid -5W+15°C, and the duration of time 4W6min by the time-static method, thus a diffusive layer 30 having diffusive cracks and orifices 32, etc. 1W5μ deep being formed on the surface 31 of the iron plate 20. After that, the plate is washed by water 23 and dried 24. Next, a photosensitive liquid is applied 25 to the surface 31 of the iron plate 20 for forming a photosensitive layer 30 thereon, and then the plate is dried 26, cut out 27 and inspected 28, thus a plate material for printing being obtained.
