Abstract

A printing apparatus applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink to a substrate. The printing apparatus includes: an image recording section that applies the ink to the surface of the printing plate; a plate surface observation unit that acquires information about the surface of the printing plate; a storage section that stores information about a reference shape serving as a reference of the surface of the printing plate; and a determination section that compares the information about the reference shape stored in the storage section with the information about the surface of the printing plate, which is obtained by the plate surface observation unit, and determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape.

First claim

What is claimed is:

1. A printing apparatus that applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink applied in the shape of the pattern to a substrate, the apparatus comprising:
an image recording section that applies the ink to the surface of the printing plate;
a plate surface observation unit that acquires information about the surface of the printing plate to which the ink has been applied;
a storage section that stores information about a reference shape serving as a reference of the surface of the printing plate to which ink has been applied;
a determination section that compares the information about the reference shape stored in the storage section with the information about the surface of the printing plate to which the ink has been applied, which is obtained by the plate surface observation unit, and determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape; and
a restoration section that restores the surface of the plate on the basis of a determination result of the determination section.

2. A printing apparatus that applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink applied in the shape of the pattern to a substrate, the apparatus comprising:
an image recording section that applies the ink to the surface of the printing plate;
a plate surface observation unit that acquires information about the surface of the printing plate to which the ink has been applied;
a storage section that stores information about a reference shape serving as a reference of the surface of the printing plate to which ink has been applied; and
a determination section that compares the information about the reference shape stored in the storage section with the information about the surface of the printing plate to which the ink has been applied, which is obtained by the plate surface observation unit, and determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape,
wherein the plate surface observation unit is to acquire information about the surface of the printing plate from which the ink applied to the printing plate in the shape of the predetermined pattern has been transferred to the substrate, and
the determination section determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape, by using information about the surface of the printing plate obtained before and after the transfer of the ink to the substrate.

3. The printing apparatus according to claim 1 ,
wherein the plate surface observation unit is to acquire information about the surface of the printing plate from which the ink applied to the printing plate in the shape of the predetermined pattern has been transferred to the substrate, and
the determination section determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape, by using information about the surface of the printing plate obtained before and after the transfer of the ink to the substrate.

4. The printing apparatus according to claim 1 ,
wherein the application of the ink to the surface of the printing plate is performed multiple times, and the plate surface observation unit acquires information about the surface of the printing plate whenever the ink is applied to the surface of the printing plate.

5. The printing apparatus according to claim 1 ,
wherein the image recording section uses an ink jet method.

6. The printing apparatus according to claim 1 ,
wherein the printing plate is an intaglio plate, and the ink is applied to a recessed portion formed in the shape of a pattern.

7. A printing method that applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink applied in the shape of the pattern to a substrate, the method comprising:
a step of applying ink to the surface of the printing plate;
an acquisition step of acquiring information about the surface of the printing plate to which the ink has been applied;
a determination step of comparing the information about a reference shape serving as a reference of the surface of the printing plate to which ink has been applied with the information about the surface of the printing plate to which the ink has been applied, and determining whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape; and
a restoration step of restoring the surface of the plate on the basis of a result of the determination step.

8. The printing method according to claim 7 , further comprising:
a step of acquiring information about the surface of the printing plate after transferring the ink, which is applied to the printing plate in the shape of the predetermined pattern, to the substrate; and
a step of determining whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape, by using information about the surface of the printing plate obtained before and after the transfer of the ink to the substrate.

9. The printing method according to claim 7 ,
wherein the application of the ink to the surface of the printing plate is performed multiple times, and information about the surface of the printing plate is acquired whenever the ink is applied to the surface of the printing plate.

10. The printing method according to claim 7 ,
wherein the application of the ink to the surface of the printing plate is performed by an ink jet method.

11. The printing method according to claim 7 ,
wherein the printing plate is an intaglio plate, and the ink is applied to a recessed portion formed in the shape of a pattern.
