Printing mold 4
is fixed. A transfer roll is disposed as a printing plate 5 on the right side of the printing type roll 2, and a cylindrical shaft 6 is disposed on the right side of the printing plate 5 in contact with the printing plate 5. Both the ink application roll 1 and the printing plate 5 rotate in a counterclockwise direction,
Further, both the printing mold roll 2 and the shaft body 6 are rotating in the same direction as clockwise. Corrosion-resistant ink is applied from the ink application roll 1 to the printing mold 4, corrosion-resistant ink is applied from the printing mold 4 to the printing plate 5, and when the shaft 6 in contact with the printing plate 5 rotates once, As shown in FIG. 2, corrosion-resistant ink is applied around the corroded portion 7 of the shaft. The process of rotating the shaft 6 in contact with the printing plate 5 once and applying corrosion-resistant ink to the periphery 7 of the corroded portion of the shaft is simple in structure and operation and can be easily automated. Next, the corroded portion 8 of the shaft body is immersed in a corrosive liquid to be corroded, and the corroded portion 8 is formed into a herringbone-shaped groove 9 for generating dynamic pressure, as shown in FIG. Then, when the shaft body 6 is immersed in a stripping liquid, the shaft body 6 is removed as shown in FIG.
Corrosion-resistant ink is removed from the

なされる。 FIG. 4 shows another embodiment of the process of applying corrosion-resistant ink around the corroded part of the shaft body. is embedded in a herringbone shape, and the printing plate 5 includes a mesh portion 11 and a resin portion 12. Corrosion-resistant ink is applied to the upper surface of the printing plate 5 to fill the mesh portion 11 with the corrosion-resistant ink, and the printing plate 5 is moved to the right as shown in FIG. 4, and the shaft 6 is rotated once. let At this time, when the corrosion-resistant ink on the top surface of the printing plate 5 is simultaneously peeled off with the squeegee 13, the corrosion-resistant ink is exposed around the corroded part 7 of the shaft that is in contact with the printing plate 5, as shown in FIG. Painted. The process of rotating the shaft 6 in contact with the printing plate 5 once and applying corrosion-resistant ink to the periphery 7 of the corroded portion of the shaft is simple in structure and operation and can be easily automated.
