Abstract

PURPOSE:To obtain a metallic screen printing plate which is superior in figuring accuracy, by a method wherein a printing plate layer constituting a figure is formed on a base surface through primary plating, a base is put and sunk on metallic gauze provided on a frame in a stretched state and the printing plate layer is made to adhere to the metallic gauze by a secondary plating. CONSTITUTION:A pattern film 8 is made to adhere closely to a base 1 made of a metal by applying a photosensitive resin layer 7 to the base 1, degreasing and surface fixing are performed by performing exposing and developing through irradiation of ultraviolet rays and a printing plate layer 2 constituting a figure is formed by applying Ni plating to a removed part. A printing surface of stainless gauze provided on a frame 3 in a stretched state is degreased and fixed, the base 1 is sunk into the metallic gauze 4 by a pressure plate 5 so that the printing plate layer 2 touches the metallic gauze 4, and secondary plating layer 6 is applied to the outer circumference of a wire 4a of the metallic gauze 4 and the surface of the printing plate layer 2 is applied to the circumference of the metallic gauze 4 to which the printing plate layer 2 is stuck closely by peeling off the base 1, which is made into a metallic screen printing plate. With this construction, the metallic screen printing plate which is superior in figuring accuracy is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a metal screen plate whose plate surface is made of a metal plate.

The conventional method for manufacturing screen plates has been a so-called combination bonding method.

That is, first, the Tetron gauze is stretched over the frame, and then the processed metal mask/screen plate is attached to the center of the Tetron gauze.
After that, the Tetron gauze that was in contact with the metal mask/screen surface was cut and removed. However, with this method, if the Sunagawa tension of Tetron gauze is 10 kg/cj, which is the tensile limit of Tetron gauze, the metal mass will be
The screen plate itself stretches, resulting in poor dimensional accuracy.

Therefore, if the tensile force of the Tetron gauze was kept at 6 to 7 kg/-, elongation of the metal mask/screen plate could be prevented, but because the tension was low, elongation occurred during printing, resulting in poor printing accuracy. .

The present invention has been made in view of the above problems, and its purpose is to provide a method for manufacturing a metal screen plate that does not cause elongation during printing and can also improve dimensional accuracy during manufacturing. It is in.

Hereinafter, i' will be explained in detail based on the embodiment shown in the drawings. 1 to 7 show the manufacturing process of a metal screen plate. First, as shown in Figure 1, a photosensitive 1) (oil layer 7) is applied to the bottom surface of a metal substrate 1 (the coating thickness is 0.0
04mm -0,005mm), here the substrate 1 is made of stainless steel and has a thickness of 1.51 to 2.01.
Next, as shown in Figure 2, the pattern film 8 is attached to the photosensitive resin J.
After that, as shown in Fig. 3, the removed part is exposed to ultraviolet rays, developed, degreased and smoothed, and the removed part is subjected to primary plating with the same thickness as the photosensitive resin layer 7 in a nickel plating bath. A plate Fi2 composing a figure is formed by applying the same process.

Next, after degreasing and smoothing the printed surface of the stainless steel gauze stretched over the frame 3, the substrate 1 is placed on the metal gauze 4 made of stainless steel so that the second side of the plate layer is in contact with the metal gauze 4 made of stainless steel, as shown in FIG. The substrate 1 is further covered with metal gauze 4 by the thickness of the substrate 1 using a pressing plate 5.
Submerge in Then, in this state, secondary plating is performed using the push plate 5 and the substrate 1 as cathodes, and the wire 4 of the gold-plated wire 4 is coated as shown in FIG.
Secondary plating on the outer periphery of a and the plate JifZ surface [6 (thickness is 0
．． Therefore, the secondary plating eyebrows 6 are electrodeposited on the plate layer 2 and not on the photosensitive resin layer 7.

Next, the press plate 5 is removed and the substrate 1 is peeled off from the metal gauze 4. In this case, since the substrate 1 is made of stainless steel, the plate layer 2 is easily peeled off from the substrate 1 and has good adhesion to the metal gauze, and the secondary plating layer 6 is also formed around the wire 4a of the metal gauze 4. Because of this, the plate layer 2 does not easily ff1ll Xi.

Finally, apply emulsion around the metal gauze 4 as shown in Figure 7,
This figure shows a completed gold clay screen plate A after sealing 9.

The plating conditions are as follows.

Nickel sulfamate 450g/j2boric acid
40g/f surfactant 2
0cc/fpo 4.0~4.
5 Temperature: 48 to 50°C Current density: 4 to 6 A/di As described above, the present invention involves forming the plate layer constituting the figure on the substrate surface by primary plating, and then applying it to the metal gauze stretched over the layer. The substrates were stacked, and then the substrates were pressed with a pressing plate and submerged in the metal gauze, and then a secondary plating layer was formed on the metal gauze, and the plate 1-4 was attached to the metal gauze. A plate layer is formed by plating in one step, so even if the metal gauze is stretched over the frame with maximum tension, there will be no elongation of the figure, and no elongation will occur during printing. It has excellent pattern accuracy and rigidity, and since the secondary plating is performed with the substrate submerged in the metal gauze, the plate layer is evenly adhered to the metal gauze, resulting in even better pattern accuracy.
