In addition, it is difficult to produce the same pattern on the surface, and the printed matter is not stable. Furthermore, there is a limit to increasing the surface area of the roll 1, and there is a problem in metering the ink.

。(2) When the surface is roughened by machining, laser processing, etc.; For example, a recess 2 with a U-shaped cross section on the surface of the roll 1
When formed regularly (as shown in Figure 7), the cross-sectional shape is 7.
When the letter-shaped recesses 3 are formed regularly (as shown in FIG. 8),
Another example is a case where recesses 4 having a curved cross-sectional shape are formed regularly (as shown in FIG. 9). However, in the case of machining or laser processing, the ink 5 is kept in a sealed state (in the closed state) due to the nip width W of the roll (see Figure 10), regardless of the size and depth of the recesses, and the density of the number of recesses relative to the roll surface area. (see Figure 11),
The pattern on the roll surface is reproduced on the printed matter. In addition, in FIG. 10, c16 is a convex portion, and 7 is a concave portion.
■高価な装置を使用するため製造コストが高くなる。■Manufacturing costs are high because expensive equipment is used.
■研磨加工と比ベパターン化出来るという利点を有する

い。(2) When the recesses 6 are formed regularly as shown in FIG. 12, the pattern on the surface of the roll is reproduced on the printed matter, although there are considerable differences depending on the angle of the recesses with respect to the circumferential direction of the roll. Note that if the recesses are made smaller in the vertical and horizontal directions, the effect on pattern reproduction on printed matter will be reduced;
The amount of ink is not perfect, and the density of the printed matter is poor.

Rubber powder 1 with an average particle size of 80 mesh before it dries.
6 was uniformly applied, another adhesive was further sprayed to fix the rubber powder 16 to the adhesive 15, thereby forming a mother roll 17 (as shown in FIG. 4(b)). Next, a release agent (not shown) is applied to the outer periphery of this mother roll 17, and then, for example, rubber is wound by a generally known method and vulcanized to form a cylindrical body 18 made of rubber.

ストを低減できる。Therefore, according to the method of the present invention, the rubber powder 16 is added to the core metal 1.
By uniformly coating the outer periphery of 1, a mother roll 16 having a complex pattern on the surface is formed, and this mother roll 16
A cylindrical body 19 having an uneven surface with an irregular surface is formed by applying a mold release agent and applying a fluid to the cylindrical body 19.The cylindrical body 19 is then pulled out from the master roll 17 while being reversed, and the cylindrical body 18 is further separated in this state. By attaching the prepared iron core 19 via the rubber layer 20 and adhesive layer, an ink delivery roll having an irregular pattern on its surface can be obtained. Therefore, if this roll is used, it is possible to increase the ink content on the roll surface, increase the amount of ink to be measured, and perform high-quality printing without reproducing the pattern on the roll surface in the printed matter. In fact, when the roll according to the present invention was used as a keyless ink delivery roll of an offset printing machine, high-quality printing could be performed without the pattern on the roll surface being reproduced on the printed matter. Further, unlike conventional machining and laser processing, there is no need to use expensive equipment, and manufacturing costs can be reduced.

However, when rolling the sheet, roll it so that the seams are as small as possible. Next, a tape was wrapped over it and heated to bring the sheet into close contact with the rubber layer around the outer periphery of the iron core. Thereafter, the tape on the outer periphery was removed to produce an ink delivery roll having the same structure as in Example 1. According to Example 2, the same effects as in Example 1 were obtained.
