る。BACKGROUND OF THE INVENTION A plate cylinder used in a single-cylinder stencil printing device generally includes a metal cylinder as a support cylinder, and the metal cylinder has an ink-permeable cylinder having a large number of small holes for ink passage. It has a porous structure part and an ink-impermeable non-porous part having no small holes to which the base paper retaining means can be attached, and furthermore, the porous structure part has a porous structure part and a non-porous part which is impermeable to ink and does not have any small holes to which the base paper retaining means can be attached. It has a weir element on the outer circumferential surface of the boundary between the structural part and the non-porous part, and this metal cylindrical body for the plate cylinder is disclosed in Japanese Patent Application No. 126933/1983 filed by the same applicant as the present applicant. (Japanese Patent Application Laid-Open No. 57-51482) has already been proposed.

で粗面にすることが行われている。 The weir element is fixed to the outer peripheral surface of the metal cylindrical body for the plate cylinder by adhesion or screen printing, but if the fixed surface is too smooth, sufficient fixing strength cannot be obtained and it will easily peel off. Therefore, conventionally, the bonding surface has been roughened to a certain extent using sandpaper or the like.

ることが難しい。 Therefore, in order to arrange the weir element, it is necessary to roughen the fixing surface of the weir element, that is, a part of the outer peripheral surface of the metal cylindrical body for the plate cylinder. Because of this, the productivity of metal cylinders for plate cylinders is low, and it is difficult to obtain a rough surface with excellent uniformity. It is difficult to manufacture the body.

とする板状体の製造法によつて達成される。Structure of the Invention According to the present invention, the above object is to provide a method for manufacturing a plate-like body having through holes in some parts and surface depressions in other parts, and to eliminate resin masking dotted on a part of the surface. On the applied master electrode, an electrodeposited layer of the electrolytic eluate is grown while restricting the electrodeposition of the electrolytic eluate at the resin masking part, and at this time, the degree of growth of each electrodeposited layer and the shape of each point are By adjusting the area of the resin masking, the electrodeposited layer does not grow to the center of the dotted resin masking in the part of the dotted resin masking where the area is large, thereby forming the through hole, and the point where the area is small. This is achieved by a method for producing a plate-like body, characterized in that the surface recesses are formed by growing an electrodeposited layer in the portion of the dot-like resin masking until it covers the center of the dot-like resin masking.

形成される。 The entire metal cylindrical body 2 for plate cylinder, including the porous structure part 7 and the non-porous part 8, is manufactured by electroforming, and the rough surface part 8a is electroformed to form the porous structure part 7 and the non-porous part 8. Therefore, it was formed at the same time. The electroforming of the metal cylindrical body 2 for the plate cylinder is performed according to the dotted masking resin pattern formed on the surface of the master electrode member 30, as shown in FIG.
This masking resin pattern is one of the dotted patterns 3 in the part where the porous structure part 7 is to be formed.
1 is large, and the size of one dot pattern 32 in the portion where the rough surface portion 8a is formed is smaller than that in the portion where the porous structure portion 7 is formed. Electroforming is performed by electrodepositing the eluted portion of the material electrode by electrolysis on the surface of the master electrode 30, and the masking resin portion provided on the surface of the master electrode 30 is directly electrodeposited on the surface. Therefore, if the size of one dot pattern is relatively large, that part will become a hole, but if the size of one dot pattern is relatively small, the masking resin will grow due to the growth of the electrodeposited layer. The surface is covered with depressions, and the collection of depressions 33 forms a rough surface.

板状体を製造することができる。 As shown in FIG. 3, the masking resin pattern is a combination of a dot pattern 31 with a large area and a dot pattern 32 with a small area. A through-hole 6 is formed at 31, and a depression 33 is formed on the surface at a small-area dot pattern 32, as shown in Figures A to D as four stages accompanying the growth of the electrodeposited layer. FIG. As shown in these figures A to D, as the electrodeposition layer D grows on the exposed portion of the master electrode member 30 that is not covered with the masking resin, the electrodeposition layer overhangs the masking. Therefore, as shown in D in the figure, on the dot pattern 31 with a large masking area, the electrodeposition layer has not yet grown to the center of the masking, and on the dot resin masking pattern 32 with a small area, the electrodeposition layer does not grow. It grows until it covers the center. Therefore, by adjusting the size of the dotted pattern of the dotted resin masking and the degree of growth of the electrodeposited layer, it is possible to form a plate with through holes in some parts and surface depressions in other parts, as shown in Figure D. body can be manufactured.
