Abstract

A printing plate for gravure printing includes a gravure roll with a cylindrical shape, and printing portions corresponding to a graphic pattern to be printed is provided on an outer circumferential surface thereof. Each of the printing portions includes first banks extending in a substantially parallel direction to a rotation direction, second banks extending in a direction substantially orthogonal to the rotation direction and in each of which at least one end portion is connected to the first banks, and cells defined by the first banks and the second banks, and in the cell located at a print starting end portion of each of the printing portions which first comes into contact with a printing object in the rotation direction, a partition bank which divides the cell in a diagonal direction is provided.

First claim

What is claimed is:

1. A printing plate for gravure printing in which a printing paste is applied on a printing object to provide a predetermined graphic pattern by a gravure printing method, the printing plate for gravure printing comprising:
a gravure roll with a cylindrical or substantially cylindrical shape; wherein
a plurality of printing portions corresponding to a graphic pattern to be printed are provided on an outer circumferential surface of the gravure roll;
each of the plurality of printing portions includes a plurality of first banks each extending in a parallel or substantially parallel direction to a rotation direction of the gravure roll, a plurality of second banks each extending in a direction orthogonal or substantially orthogonal to the rotation direction and in each of which at least one end portion is connected to the plurality of first banks, and a plurality of cells defined by the plurality of first banks and the plurality of second banks; and
in a cell of the plurality of cells located at a print starting end portion of each of the plurality of printing portions which first comes into contact with the printing object in the rotation direction, a partition bank which partitions the cell in a diagonal direction of the cell is provided.

2. The printing plate for gravure printing according to claim 1 , wherein a width of each end portion of each of the plurality of first banks, in which the each end portion is located in a printing direction and the width is defined along the direction orthogonal or substantially orthogonal to the printing direction, is larger than a width of a portion other than the each end portion of each of the plurality of first banks, in which the width is defined along the direction orthogonal or substantially orthogonal to the printing direction.

3. The printing plate for gravure printing according to claim 1 , wherein first end portions of the plurality of second banks are connected to the plurality of first banks in a staggered arrangement.

4. The printing plate for gravure printing according to claim 1 , wherein a width of a second end portion of each of the plurality of second banks, in which the second end portion is not connected to any of the plurality of first banks and the width is defined along the parallel or substantially parallel direction to the printing direction, is larger than a width of a portion other than the second end portion of each of the plurality of second banks, in which the width is defined along the parallel or substantially parallel direction to the printing direction.

5. The printing plate for gravure printing according to claim 1 , wherein one end portion of the partition bank is connected to the plurality of first banks.

6. The printing plate for gravure printing according to claim 1 , wherein an angle defined by intersecting a center line of the partition bank along an extending direction of the partition bank and a center line of each of the plurality of first banks along an extending direction of each of the plurality of first banks with each other is about 15° or greater and about 75° or less.

7. The printing plate for gravure printing according to claim 1 , wherein the partition bank is not connected to any of the plurality of first banks.

8. The printing plate for gravure printing according to claim 1 , wherein
each of the plurality of printing portions is provided with a narrow width portion in which a width of each of the plurality of printing portions is narrow in the direction orthogonal or substantially orthogonal to the rotation direction; and
a second partition bank which partitions the cell to obliquely intersect with respect to the printing direction is provided in the cell located on an outline of the narrow width portion.

9. The printing plate for gravure printing according to claim 1 , wherein
each of the plurality of printing portions is provided with a wide width portion in which the width of each of the plurality of printing portions is wide in the direction orthogonal or substantially orthogonal to the rotation direction; and
a third partition bank which partitions the cell in a diagonal direction of the cell is provided in the cell located at a print starting end portion of each of the plurality of printing portions which first comes into contact with the printing object among the cells located in the wide width portion.

10. The printing plate for gravure printing according to claim 1 , wherein the plurality of printing portions are provided in a matrix or substantially matrix shape along the rotation direction and an axial center direction of the printing plate.

11. The printing plate for gravure printing according to claim 1 , wherein each of the plurality of printing portions has a rectangular or substantially rectangular shape or a substantially rectangular shape in which a narrow width portion or a wide width portion is partially provided.

12. The printing plate for gravure printing according to claim 1 , wherein
each of the plurality of printing portions includes a plurality of gap portions provided between a portion of the plurality of first banks and a portion of the plurality of second banks; and
the gap portions connect adjacent cells to one another.

13. A method of manufacturing a multilayer ceramic electronic component, the multilayer ceramic electronic component including a multilayer body including a plurality of laminated ceramic layers and a plurality of laminated inner electrode layers and outer electrodes provided at a first end portion of the multilayer body and a second end portion of the multilayer body, the method of manufacturing the multilayer ceramic electronic component comprising:
printing an inner electrode pattern on a ceramic green sheet using the printing plate for gravure printing according to claim 1 .

14. The method of manufacturing a multilayer ceramic electronic component according to claim 13 , wherein a conductive paste is supplied to the printing plate by injecting the conductive paste toward the printing plate.
