Printing plate, laminated ceramic electronic component producing method, and printer
A print pattern of a printing plate used in intaglio printing includes plural partition walls and a groove-shaped cell unit. The plural partition walls are continuously extended in a printing direction, and arranged at predetermined intervals in an orthogonal direction. The cell unit is formed between the partition walls adjacent to each other, and a printing paste (conductive paste) is retained in the cell unit. Plural printing direction walls that are arranged in a zigzag manner in the printing direction are coupled to each other by a coupling walls that are arranged in the printing direction walls adjacent to each other in the printing direction, thereby forming the partition wall.
1. A printing plate for intaglio printing that obtains a predetermined graphic pattern by printing a printing paste on an article to be printed, said printing plate comprising:
a plurality of periodic repeating print patterns corresponding to a periodic repeating graphic pattern to be printed being formed in a surface of a plate material,
a predetermined direction along the surface of the plate material being configured to correspond to a printing direction of the article to be printed, and
each of the plurality of print patterns including a plurality of partition walls and a groove-shaped cell unit, and each of the plurality of partition walls including a plurality of printing direction walls and a coupling wall,
the plurality of partition walls being arranged at predetermined intervals in a direction orthogonal to the printing direction,
the coupling wall being arranged so as to couple the printing direction walls adjacent to each other in the printing direction,
the groove-shaped cell unit in which the printing paste is to be retained being provided between the partition walls adjacent to each other,
wherein the plurality of printing direction walls define an area comprising a plurality of first portions and a plurality of second portions,
wherein the area is provided in a plane defined by the printing direction and a direction orthogonal to the printing direction,
wherein each of the plurality of first portions and the plurality of second portions is longer in the printing direction than the direction orthogonal to the printing direction when viewed in a plan view, and
wherein the plurality of first portions is shifted in the direction orthogonal to the printing direction from the plurality of second portions.
2. The printing plate according to claim 1 , wherein the plurality of printing direction walls are arranged parallel to each other at predetermined intervals in the direction orthogonal to the printing direction.
3. The printing plate according to claim 1 , further comprising a plurality of end projection walls that are formed at at least one of ends of the print pattern in the direction orthogonal to the printing direction.
4. The printing plate according to claim 1 , wherein the plate material is a cylindrical gravure roll, and the surface of the plate material is an outer circumferential surface of the gravure roll.
5. The printing plate according to claim 1 , wherein the printing plate is formed in a flat plate material.
6. The printing plate according to claim 1 , wherein the printing plate is an offset printing plate in which the printing paste is printed on the article to be printed from the printing plate through an intermediate transfer body.
7. The printing plate according to claim 1 , wherein a cell width that is of a size in the direction orthogonal to the printing direction of the groove-shaped cell unit varies periodically along the printing direction.
8. The printing plate according to claim 1 , wherein a main part of the printing direction wall is configured to be parallel to the printing direction.
9. The printing plate according to claim 1 , wherein the coupling wall is formed such that a minor angle of angles formed by a center line of the coupling wall and a center line of the adjacent printing direction wall is greater than 90° and less than 180° in a plan view.
10. The printing plate according to claim 1 , wherein a notch that communicates the cell units partitioned by the printing direction wall is formed in a part of the printing direction wall.
11. The printing plate according to claim 1 , wherein a height of at least one of the printing direction wall and the coupling wall is lower than a height of the outer circumferential surface of the gravure roll.
