Abstract

A gravure printing plate includes a cylindrical or substantially cylindrical gravure roller with a peripheral surface. Plural cells corresponding to a pattern to be printed are disposed on the peripheral surface of the gravure roller. First and second regions are provided on the peripheral surface of the gravure roller. The pattern to be printed includes at least two patterns. Plural cells corresponding to one of the two patterns are disposed in the first region. Plural cells corresponding to the other one of the two patterns are disposed in the second region.

First claim

at least two regions are provided on the peripheral surface of the gravure roller;
the pattern to be printed includes at least two patterns;
a first group of the plurality of cells corresponding to one of the at least two patterns is disposed in one of the at least two regions;
a second group of the plurality of cells corresponding to another one of the at least two patterns is disposed in another one of the at least two regions;
the first group of the plurality of cells are disposed in multiple rows in a first direction with respect to a rotation direction of the gravure roller;
the second group of the plurality of cells are disposed in multiple rows in a second direction with respect to the rotation direction of the gravure roller;
the first direction is different from the second direction;
each of the plurality of cells that are disposed in the one of the at least two regions has a shape and a size that is the same as or substantially the same as all remaining ones of the plurality of cells that are disposed in the one of the at least two regions;
each of the plurality of cells that are disposed in the another one of the at least two regions has a shape and a size that is the same as or substantially the same as all remaining ones of the plurality of cells that are disposed in the another one of the at least two regions; and
in the step of performing printing, the multiple rows of each of the first and second groups of the plurality of cells provides a plurality of electrodes.

2. The gravure printing method according to claim 1 , wherein, in the step of performing printing, printing speeds for the at least two regions are the same or substantially the same.

3. The gravure printing method according to claim 1 , wherein the first group of the plurality of cells defines a stripe-shaped pattern continuously disposed along the rotation direction of the gravure roller.

4. The gravure printing method according to claim 1 , wherein the first group of the plurality of cells defines a bar shape which is continuously disposed along the rotation direction of the gravure roller and which has a predetermined width in a direction perpendicular or substantially perpendicular to the rotation direction of the gravure roller.

5. The gravure printing method according to claim 1 , wherein the second group of the plurality of cells defines a stripe-shaped pattern continuously disposed along a direction perpendicular or substantially perpendicular to the rotation direction of the gravure roller.

6. The gravure printing method according to claim 1 , wherein the second group of the plurality of cells defines a bar shape which is continuously disposed along the rotation direction of the gravure roller and which has a predetermined width in a direction perpendicular or substantially perpendicular to the rotation direction of the gravure roller.

7. The gravure printing method according to claim 1 , wherein the at least two regions are arranged side by side in the rotation direction of the gravure roller.

8. The gravure printing method according to claim 1 , wherein each of the plurality of cells includes dent portions.

9. The gravure printing method according to claim 1 , wherein each of the plurality of cells are shaped to form the pattern to be printed to include a cross-shaped or substantially cross-shaped electrode.

10. The gravure printing method according to claim 1 , wherein the plurality of cells are not continuously provided along the rotation direction of the gravure roller.

11. The gravure printing method according to claim 1 , wherein the plurality of cells are not continuously provided along a direction perpendicular or substantially perpendicular to the rotation direction of the gravure roller.

12. The gravure printing method according to claim 1 , wherein the at least two regions are arranged side by side in a direction perpendicular or substantially perpendicular to the rotation direction of the gravure roller.

13. The gravure printing method according to claim 1 , wherein the at least two regions are arranged side by side in an oblique direction to the rotation direction of the gravure roller.

14. The gravure printing method according to claim 1 , wherein
the first direction is along or substantially along the rotation direction of the gravure roller; and
the second direction is perpendicular or substantially perpendicular to the rotation direction of the gravure roller.

15. A manufacturing method for an electronic component, comprising:
a step of performing printing by applying a conductive paste to a surface of a substrate for the electronic component by using a gravure printing plate including:
a cylindrical or substantially cylindrical gravure roller including a peripheral surface; and
a plurality of cells disposed on the peripheral surface of the gravure roller, the plurality of cells corresponding to a pattern to be printed; wherein
at least two regions are provided on the peripheral surface of the gravure roller;
the pattern to be printed includes at least two patterns;
a first group of the plurality of cells corresponding to one of the at least two patterns is disposed in one of the at least two regions;
a second group of the plurality of cells corresponding to another one of the at least two patterns is disposed in another one of the at least two regions;
