Abstract

PROBLEM TO BE SOLVED: To form stably a superior image of high resolution and high dimension accuracy for a suspended metal with a metal mask on a printed surface central section of a screen mesh, and also provide its manufacturing method. SOLUTION: A metal mask 3 is bonded and fixed on a printing surface central section of a screen mesh 1 with its outer periphery bonded and fixed on a block form, and resin is applied and solidified on the squeegee side of the screen mesh 1, and a through-hole is formed slightly wider than the image through-hole width of the metal mask 3 in compliance with the image through- hole of the metal mask 3 and resin is dried and solidified.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a screen printing suspended metal mask having a metal mask attached to the center of a screen mesh.

[0002]

2. Description of the Related Art FIGS. 5 and 6 show a conventional suspended metal mask for screen printing. Reference numeral 10 denotes a screen mesh in which an outer peripheral edge is bonded to a frame 11, and a metal mask 12 is bonded to a printing surface side at a central portion thereof to form a suspended metal plate for screen printing.

[0003]

As shown in FIG. 7, an ink or a paste is applied on a screen mesh 10, and the squeegee 13 is slid while lowering the ink or the paste 14 in a direction indicated by an arrow. The lower print substrate 1 placed on the table 15 through the twelve image through holes 12a
6. Apply on top. In the prior art, the edge of the image through hole 12a of the metal mask 12 and the screen mesh 1
0 or ink or paste 14a in the gap formed between
When the metal mask 12 is separated from the print substrate 16 after printing, the ink or paste 14
a, the image-forming holes 12a of the metal mask 12
Because the amount of ink or paste falling from the ink varies,
The amount of transfer to the print substrate 16 becomes unstable, and this phenomenon has a problem that it is difficult to stably obtain an excellent image with high resolution.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and a metal mask is bonded and fixed to a center portion of a printing surface of a screen mesh having an outer periphery bonded and fixed to a plate frame. A resin is applied and solidified on the surface side, a through hole is formed slightly wider than the image through hole width of the metal mask in accordance with the image through hole of the metal mask, and the resin is dried and solidified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to an embodiment shown in FIGS. Reference numeral 1 denotes a screen mesh having an outer peripheral edge adhered to a frame 2, a metal mask 3 at a central portion of a printing surface thereof is adhered, and a resin 4 is applied and solidified on a screen mesh side of the metal mask portion. A through hole 4a is formed in the photosensitive emulsion 4 in accordance with the hole 3a by printing or the like. The through holes 4a may be formed by any means, and are formed slightly wider (about 30 to 500 μm) than the image through holes 3a of the metal mask 3. The upper surface of the solidified resin 4 is positioned near the upper surface of the screen mesh 1. Instead of the photosensitive emulsion 4, a reactive curable resin such as epoxy or polyurethane may be used.

Next, the operation will be described. An ink or paste 8 is applied on the screen mesh 1 of the suspended metal on the printing material 7 placed on the table 6, and the squeegee 5 is slid while applying a downward pressure in the direction of the arrow to remove the ink or paste 8. The metal mask 3 is applied on the lower print substrate 7 through the image through hole 3a. At this time, the metal mask 3
Since the image through-holes 4a of the solidified resin 4 that match the image through-holes 3a are formed, ink or paste 8 or the like 8 can be easily removed from the image through-holes 3a, and has excellent resolving power and dimensional accuracy. Image can be obtained stably.

[0007]

According to the present invention, a metal mask is bonded and fixed to the center of the printing surface of a screen mesh whose outer periphery is bonded and fixed to a plate frame, and a resin is applied and solidified on the squeegee surface side of the screen mesh, and the image of the metal mask is transparent. Since the perforation is slightly wider than the perforation width of the image of the metal mask according to the holes and the resin is dried and solidified, the paste rolls well,
The peeling of the fine pattern is also reduced, and the ink or the paste is easily removed from the through holes for the image, so that an excellent image having a high resolution and dimensional accuracy can be stably obtained.
