Description

The present invention relates to a printing apparatus by a reverse printing method using a removal plate and a printing method.

In general, printing is the reproduction of a large number of images and characters by filling a printing plate with ink and transferring it to a medium such as paper. In such conventional printing, the focus is on transferring the ink pattern formed on the printing plate to the medium with high accuracy, and many printing methods have been proposed. Further, in fields such as semiconductors, many printing methods for patterning functional materials are also known.

In the invention described in Patent Document 1, a solid coating surface of ink is formed on a blanket, and an unnecessary portion is removed from the solid coating surface by a negative pattern letterpress called a removal plate, and the remaining positive pattern ink. A reverse printing method has been proposed in which the ink is transferred to a printing substrate and printed. According to this method, since a pattern in which unnecessary ink is removed from the ink-coated surface can be formed, the influence of ink flow is small, the flatness is high, and a high-definition pattern can be printed.

In the invention described in Patent Document 2, in the reverse printing of Patent Document 1, a printing method for removing an ink film with a removal plate on which a lithographic ink pattern is formed is proposed. By using the flat plate removal plate, it is possible to suppress the occurrence of transfer defects due to the bottoming out phenomenon of the ink film that occurs in the letterpress removal plate, and it is possible to obtain a higher quality and highly accurate ink pattern.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, the first embodiment of the present invention will be described.

FIG. 1 is a block diagram showing a configuration of a printing apparatus 100 according to a first embodiment of the present invention.

In FIG. 1, the printing apparatus 100 includes a transfer cylinder 111, an ink coating machine 112, a dryer 113, and an ink coating surface 114.

The transfer cylinder 111 has a cylindrical shape, is made of a metal material, and has a surface on which the ink 10 can be solidly applied. The surface material of the transfer cylinder 111 may be any material as long as it does not repel the ink 10, but a blanket material made of silicone rubber having excellent ink wettability and ink solvent absorption is used as the surface material. It may be formed. Since the surface of the transfer cylinder 111 is directly linked to the smoothness of the pattern surface for reverse printing, it is necessary to maintain high smoothness when printing a pattern that requires smoothness. Further, the transfer cylinder 111 has a cylindrical shape assuming a roll-to-roll method, but the present invention is not limited to this, and a belt-shaped configuration may be used. If the transfer cylinder 111 has a sheet-fed printing apparatus configuration, it is a plate. It may have a shaped structure.

The ink coating machine 112 is a device that forms an ink coating surface 114 on the surface of the transfer cylinder 111. The ink coating machine 112 may be appropriately selected according to the material and film thickness of the ink 10, and die coat, spray coat, mist coat, curtain coat, gravure coat, knife coat and the like can be selected. The thickness of the ink-coated surface 114 is such that the ink-coated surface 114 is thinned or the ink has a low condensing force because a tearing phenomenon occurs due to the condensing force of the ink 10 itself and the contact force between the removal pattern 123 and the ink 10. It is desirable to use 10, which enhances patterning reproducibility.

The dryer 113 is a device that dries the ink-coated surface 114 formed on the surface of the transfer cylinder 111. Since the state of the ink-coated surface 114 changes depending on the drying state, the dryer 113 can be appropriately selected according to the material and film thickness of the ink 10.

The ink 10 on the ink-coated surface 114 left on the transfer cylinder 111 is transferred to the printing base material 142 to form the printing pattern 143.

The printing substrate 142 may be any material as long as it does not repel the ink 10, but paper, film, semiconductor material, or the like can be selected.

The transfer impression cylinder 141 constitutes a mechanism for transferring the ink 10 on the ink-coated surface 114 of the transfer cylinder 111 remaining by transfer removal to the printing base material 142 to form the printing pattern 143.
