The method and printing machine shown in Japanese Patent No. 2-121056 are commonly used. The method and printing machine will be explained below based on FIG. 3. In FIG. Even if the squeegee 2 is lowered to the outside of the intaglio plate 4, the squeegee 2 stops with a certain gap from the intaglio plate 4 in order to spread enough ink to fill the grooves of the intaglio plate 4. In the step (b), the squeegee 2 is moved to the right in the drawing to spread the ink 5 all over the grooves and non-grooves of the intaglio 4, and then the squeegee 2 is raised as shown in Figure 3 (c). Then, the lowered doctor blade 3 is brought into contact with the ink-free area on the intaglio plate 4. Then, fill the ink 5 into the grooves of the intaglio plate 4 while moving it to the right in the drawing, completely scraping off the ink 5 in the non-grooved areas. 4 and move it toward the right in the drawing to transfer the ink pattern on the intaglio plate 4. Then, as shown in FIG. A pattern is printed on a printing medium 7.

When the squeegee and intaglio plate are fitted with a certain gap, there is hardly any pressure applied to the ink filled into the grooves of the intaglio plate, and sufficient pressure is not applied when filling the ink with the doctor blade. This is because there is no
