Abstract

PURPOSE:To enable a single screen to perform multi-color printing by installing a partition on a screen printing plate in printing direction. CONSTITUTION:A screen is halved by a partition 2 so that a part A and a part B of a screen printing plate may be distinguished by color. A prearranged ink is inserted beforehand into printing areas A7 and B8, and a squeegee 9 with each length a, b from both ends remaining as it is and a part between the lengths removed and an ink repeller are provided. Thus multi-color printing can be performed on a plurality of containers to be printed with simple operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a multicolor printing device using a silk screen.

[Prior art and its problems] Multicolor printing in traditional silk screen.

Several types of screens were prepared depending on the type of color, and the screens were reinstalled for each color, or printing machines were used for each color, but the ink for the screens was slow to dry and the work was difficult. The efficiency of setting up the process was ``ε〈, and it was also complicated.

[9. Purpose of the present invention] This invention was made in view of the above-mentioned 11 circumstances, and its [J purpose is that it is possible to print in multiple colors on a single screen using a conventional Nork screen printing machine. The aim is to provide a multi-color printing device with a multi-color printing system.

[Summary of the Invention] In order to achieve the above-mentioned eleventh objective, the present invention applies ink of different colors to a plurality of printing units, each of which is constructed by attaching a printing plate along the printing direction to an original plate mounting frame to which a screen is attached. This multi-color printing device is characterized by a squeegee that is inserted to press and slide the screen in each printing section, and an ink returner for correcting the unevenness of the ink.

Embodiment 1 FIG. 1 is a perspective view of a screen original mounting frame and a partition plate showing a final embodiment. The original plate mounting frame 1 is made by assembling wooden or metal square pieces into a rectangular shape to match the printing frame (not shown) of a printing machine, and the screen original plate is attached to the bottom surface of the original plate mounting frame 1. Assuming that the direction indicated by the double-headed arrow is the printing direction, the A and B portions of the screen original plate
Separate the parts using partition plate 2 so that the colors can be separated. The partition plate 2 is also made of the same material as the original plate mounting frame 1, and has notches 4 on the upper surface of both ends thereof into which the outer tips of the fasteners 3 are inserted. The tightener J43 is a U-shaped metal fitting with a screw 5 attached to one side, and there is a presser plate 6 at the tip of the screw 5, and when the screw 5 is tightened, there is a gap between the tip of the tightener 3 and the presser plate 6. The square lumber and finish of the sandwiched mounting frame L! , the TI plate 2 is completely tightened.

The screen is divided into two parts by the J plate 2 serving as described above to form a plurality of printing parts. Predetermined ink is inserted into the printing portions A7 and B8. Now the width of printing part A is a
Assuming that the width of printing area B is b, as shown in Fig. 2, the printing squeegee 9 and the printing squeegee 9 when performing multicolor printing using this original plate 1r:I frame l, The ink returner 10 for returning the ink can be removed by leaving lengths a and b from both ends, respectively, or by attaching a squeegee having a width of a and an ink returner to the printing machine as shown in 3rd IA. Even if a squeegee and an ink returner having a width of b are fixed to the partition plate 2 and a width of b is respectively fixed to the above-mentioned mounting part, the operation and effect will not change at all. .

The structure described above is for two-color printing, but in the case of three-color printing, the number of partition plates 2 is increased, and a pair of partition plates with widths corresponding to the widths a, b, and c of each partition plate are used. By attaching a squeegee and an ink returner, you can print in three colors at a time.

The two-color printing process by the multicolor printing apparatus of the present invention will be explained with reference to FIGS. 4(a) to 4(d). FIG. 4(a) shows an original plate mounting frame 1 according to the present invention, with a 9J board 2 fastened within the frame. (b) shows the squeegee 9 and ink return lO for two colors and three colors, of which the squeegee 9 and ink return lO shown on the left side of the figure have been attached to the printing machine shown in (C). Insert red ink into the printing area A7 on the front side of the partition plate 2, pour H ink into the printing area B8 at the back, and move the squeegee 9 and ink returner 10 in the horizontal direction in the figure.
In the right direction, the squeegee 9 presses the screen to print, and at the right end it moves in the L direction, and in the left direction, the squeegee 10 moves down a little to return the ink that has moved with the squeegee 9.

When printing is completed after several operations, the printing material (styrofoam container) 11 is released from being pressed against the screen surface and taken out, as shown in (d).

In the figure, five containers are printed at once, with the marked part being red and the single letter part being filled with i+f.After completing one task, the ink is left to dry.

[Modifications and Applications] This invention is not limited to the above-mentioned embodiments, and various modifications and applications are possible without departing from this invention. That is, instead of the partition plate 2 of the original plate mounting frame l, it is possible to arrange a plurality of frames that fit within the plate mounting frame along the printing direction,
It should be noted that the same operation as the present invention is performed even when the squeegee and ink returner of the portion corresponding to the plate are removed.

[Effects of the Invention] As described in detail above, in this invention 151, partition plates along the printing direction are attached to the original mounting frame to which the screen original is attached to constitute each printing section, and ink of a different color is injected into each printing section. By installing a squeegee and ink returner that can be inserted and print different colors in the same process, it is a lively device that can print multiple colors on a large number of containers to be printed in the cylinder, making it extremely useful. This is the 11th major development of value.
