## Abstract

A printing device is used, which includes a substrate table having a flat surface and holding a target, an arc table having a curved portion, and a controller and configured such that the controller swings the arc table in a state in which the curved portion holding ink faces the substrate table and causes the arc table to contact the target to transfer the ink onto the target. Moreover, a printing method is used, which includes an application step of applying ink to an arc table, a receiving step of receiving part of the ink by a printing plate on a printing plate table by contact between the ink on the arc table and the printing plate, and a transfer step of transferring the ink remaining on the arc table onto a target on a substrate table.

## Claims

### Claim 1

A printing device comprising:
a substrate table having a flat surface;
an arc table having a curved portion; and
a controller,
wherein the controller moves the arc table in a state in which the curved portion holding ink faces the substrate table holding a target and causes the arc table to contact the target, or
moves the arc table in a state in which the arc table holding a target faces the substrate table holding ink and causes the substrate table to contact the target, thereby transferring the ink onto the target, wherein
the arc table is swung by moving a shaft holding the arc table along a trochoid curve.

### Claim 2 (depends on 1)

The printing device according to claim 1, wherein
the swing is along a trochoid curve with a corrected parameter, and
the corrected parameter is set such that a lowest surface of the arc table is at a certain height.

### Claim 3 (depends on 1)

The printing apparatus according to claim 1, wherein the shaft has three degrees of freedom.

### Claim 4 (depends on 3)

The printing apparatus according to claim 3, wherein the three degrees of freedom is three degrees of freedom in X-axis translation, Z-axis translation, and rotation about the Y-direction as a rotation center axis.

### Claim 5

A printing device comprising:
a substrate table having a flat surface;
an are table having a curved portion; and
a controller,
wherein the controller moves the arc table in a state in which the curved portion holding ink faces the substrate table holding a target and causes the arc table to contact the target, or
moves the arc table in a state in which the arc table holding a target faces the substrate table holding ink and causes the substrate table to contact the target, thereby transferring the ink onto the target, wherein plural shafts hold the arc table and are configured to move horizontally and vertically to swing the arc table, and wherein each shaft of the plural shafts has three degrees of freedom.

### Claim 6 (depends on 5)

The printing apparatus according to claim 5, wherein the three degrees of freedom is three degrees of freedom in X-axis translation, Z-axis translation, and rotation about the Y-direction as a rotation center axis.
