Embodiment Construction

[0050] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0051]

[0052] figure 1 It is a schematic structural diagram of the screen printing apparatus of this invention.

[0053] The screen printing apparatus 100 forms a printed layer of a desired printed pattern on the printed surface 15 of the curved substrate 13 . The screen printing device 100 has a squeegee 17 , a base 19 , a screen printing plate 21 , and a squeegee drive unit 23 .

[0054] The screen printing plate 21 is disposed on the base 19 with a predetermined gap formed between the screen printing plate 21 and the surface to be printed 15 of the substrate 13 . The squeegee 17 is arranged above the screen printing plate 21 so that the squeegee tip 25 can press the screen 27 . The squeegee drive unit 23 presses the squeegee tip 25 toward the screen 27 to move the squeegee 17 in the printing direction indicated by the arrow while sliding the squeegee...

Abstract

There is provided a screen printing apparatus, a screen printing plate, a method for manufacturing a screen printing plate, and a printing layer for printing which can be printed with a high precision and small infiltration even if the gap between the substrate and the screen printing plate is increased of the substrate manufacturing method. The screen printing apparatus presses the squeegee against the screen printing plate to form a printed layer of a desired printing pattern on the surface to be printed on a substrate having a curved surface shape. The screen is arranged on the printed surface with a gap. And a correction printing pattern is formed on the screen which corrects the printing pattern offset to a desired printed pattern as a target which is scraped by the screen and is scraped in the printing direction The printing pattern of the screen is shifted in the printing direction of the printing layer, the width direction of the blade which intersects the printing direction, and the elastic deformation in the height direction of the printing surface perpendicular to the printing direction and the width direction.

Description

technical field [0001] The present invention relates to a screen printing device, a screen printing plate, a method for manufacturing the screen printing plate, and a method for manufacturing a substrate with a printing layer. Background technique [0002] In screen printing apparatuses, it is often the case to design a screen printing plate having a printing pattern having the same shape as a pattern to be printed. That is, printing is performed by pressing the screen plate with a squeegee using a screen plate having a desired printing pattern on the surface to be printed. When this screen printing is applied to decorative printing for applications such as displays, for example, high dimensional accuracy is required. Furthermore, at the interface between the printed part and the non-printed part, it is also required to reduce bleeding. [0003] When pressed with a squeegee, the screen plate is stretched and bent, so that the printed pattern is deformed. Although this def...
