Thus, a plurality of different color parts 10, 11 are formed, and squeegees combined with the parts are provided in response to the number of the different colors and shapes. Predetermined color tone inks are filled in the parts, the squeegees are moved to conduct multi-color print by the single plate.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a multicolor printing apparatus and a printing method using the same, and is to enable multicolor printing with a single plate.

[0002]

2. Description of the Related Art Conventionally, a structure of a screen printing apparatus is shown in FIG. That is, the structure of this conventional screen printing plate is such that a screen (silk, tetron or stainless steel) mesh 2 is attached to an aluminum plate frame 1 with an adhesive agent, the sol is applied to the entire surface of the plate, and a photosensitive solution is further applied. After drying, the pattern film 3 is overlaid, exposed by printing, and developed to form a pattern 4 (a part without sol) on the screen surface. Then, when the ink 5 is put on the screen surface and the printing object 6 is exposed to move the squeegee 7,
It passes through the texture of the pattern pattern 4 and adheres to the printing medium 6 to be printed.

In order to perform color difference printing using such a printing apparatus, a screen printing plate is required for each color,
In order to perform multicolor printing, it is necessary to repeat each multicolor printing process.

[0004]

In such a conventional method, as the number of colors increases, it takes more work to process, and in the case of overprinting, the overprinting is performed in the next step while the printing portion in the previous step is in a semi-dried state. As a result, color bleeding occurs, which takes a long time to dry, making mass production difficult.

[0005]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a multi-color printing apparatus and a printing method thereof which improve the conventional printing method involving the above-mentioned steps and enable different color printing with a single plate. To do.

[0006]

A multicolor printing apparatus for achieving the above object is a printing apparatus provided with a screen printing plate and a squeegee combined with the screen printing plate, as in the invention described in claim 1. The printing plate has a plurality of color-difference parts formed by arranging ink color-dividing partitions according to a predetermined design inside the plate frame, and the squeegee to be combined with these color-difference parts depends on the number and shape of the color-difference parts. The color difference portion is filled with ink of a predetermined color tone and the squeegee is moved to enable a plurality of color difference printing with a single plate. Specifically, as in the invention described in claim 2, the squeegee is X
In addition to the direction, it may be provided with a Y direction or a meandering moving means. Further, as a multicolor printing method using such a multicolor printing apparatus, as in the invention described in claim 3,
A step of preparing a screen printing plate in which a plurality of color difference portions are formed by arranging ink color-dividing partitions according to a predetermined design on the inside of the plate frame And a step of exposing the material to be printed on the screen printing plate, a step of printing each color on the material to be printed by operating each squeegee simultaneously or separately in a predetermined direction, This can be achieved by adopting a process of drying the body.

[0007]

According to the means for achieving the above object, since a plurality of color difference portions can be formed by the partition inside the plate frame, it is possible to perform multicolor printing with a single plate. Further, by providing the squeegee with a moving means that meanders in the Y direction as well as in the X direction, multicolor printing of a complicated pattern becomes easy. When the above printing method is adopted, multicolor printing can be easily performed on the printing medium with a single plate, and the processing labor can be saved.

[0008]

[First Embodiment] FIG. 1 is a perspective view of an essential part of a multicolor printing apparatus according to the present invention, in which a plate frame 1 is made of aluminum, and a plurality of color-dividing partition plates 8 are provided inside. 9 are arranged to form large and small color difference portions 10 and 11. A screen mesh 2 made of silk, tetron, etc. is adhered to the lower surface of the plate frame 1, the partition plates 8 ... 9 by an adhesive, and the pattern patterns 12 and 13 of a predetermined design are provided on the screens of different colors. Has been formed. Such a printing plate is formed in the same manner as the conventional structure described above.

The squeegee 77 is formed with a cut 77a into which the partition plate 8 is inserted, and the smaller color difference portions 11 ... The stage 78 faces the single, larger color difference portion 10.

Reference numeral 66 denotes a part of a printing medium made of a rectangular glass bottle, which is exposed below the screen mesh with an appropriate gap. Reference numerals 56, 57, 58, and 59 are inks having different color tones, and are put in different color portions.

As a printing method using such a multi-color printing device, the multi-color printing device as described above is prepared first, and inks 56 ... And 59 of each color are put in the color difference portions 10, 11 ,. , A printed material 66 such as a rectangular glass bottle is arranged below the screen mesh 2 with a predetermined gap,
The squeegees may be moved simultaneously or separately, ink may be discharged from the crevices of the screen mesh for printing, and then the printing medium may be baked by drying. FIG. 2 is a process diagram of such a printing method.

A squeegee 7 is used for printing on a flat substrate.
7. The squeegee 78 should be operated on the same line (X direction). When printing on a cylinder or multiple sides, for example, the squeegee 77 is on one side and the squeegee 78 is on the other side.
To work separately.

[0013]

[Second Embodiment] Although the squeegee moves in one direction (X direction) in the above description, it is a printing plate having a complicated design as shown in FIG. ,
It is also possible to move the squeegee 79 in the Y direction and meander the squeegee 76. By doing so, complex multicolor printing with a change in design can be performed with the same printing process using a single plate.

[0014]

Since the present invention is constructed as described above,
Multi-color printing can be performed simultaneously in one printing process with a single printing plate, and the number of processing steps can be significantly reduced compared to the conventional multi-step printing method, and color bleeding etc. does not occur. And its printing method can be provided.
