Description

Foam transfer method using offset and screen printing {EMBOSSING TRANSCRIPTION METHOD BY OFFSET OR SCRREEN PRINTING}

The present invention relates to a foamable transfer method that can be implemented through a variety of printing techniques, and in particular, the transfer coating film is closely attached so as to be integral to the transfer object (for example, cotton, polyester and mixed surfaces thereof, etc.) The present invention relates to an embossing transfer method using offset and screen printing that can provide visual satisfaction by minimizing the size and maintaining the clarity of colors and at the same time enabling three-dimensional foaming transfer of various shapes.

In general, a method of printing a pattern or a character as a transfer ink on the upper surface of a sheet to print a figure or a character (including a number) on a transfer object such as textile paper or paper is already widely used. .

However, as is well known, the screen printing of various patterns and texts by selecting the surface of the earth is a method for improving the releasability. Although it has been adopted to form a transfer coating film of a pattern or various characters, but the printing surface of the coated paper coated with silicon is impossible to print the transfer coating film with the transfer ink, the compound powder powder on the upper surface of the earth to improve the printability The present invention has been performed by spreading or rubbing evenly to form a powder layer for promoting printing, and then printing a transfer film on the powder layer.

Therefore, since the powder layer composed of compound powder powder is placed between the upper surface of the earth and the transfer coating film, the release coating of the transfer coating may be very excellent, and thus the transfer coating may be easily pushed or separated by a small external impact and pressure. It includes the problem that the tendency is clear and its management and storage is very cumbersome.

In particular, the conventional transfer paper has a problem in that the transfer coating film is fusion-transferred only to the transfer surface of the transfer object when the transfer coating film is transferred to the transfer object by a heat fusion method, so that the peeling (departure) phenomenon and the decolorization phenomenon are remarkable.

Therefore, as a solution for solving such a problem, a "method of manufacturing an infiltrating transfer paper" has been proposed in Korean Patent Publication No. 92-873.

According to the above method, the transfer film is formed on the upper surface of the earth (transfer paper) on which the transfer coating film is formed through the screen printing method while the gas is generated on the upper surface of the earth on which the transfer coating film is printed. By imparting a penetration promotion function to penetrate the surface of textile paper, paper, etc.) to the transfer coating film, the transfer coating film is printed while the transfer coating penetrates into the surface tissue of the object to be transferred instead of just being thermally fused to the surface of the object to be transferred as in the conventional transfer paper It is possible to print permeable, so that a multi-color transfer coating film such as various patterns, characters, or fine lines can be clearly printed on the object to be transferred, and it is possible to maintain a unique color that does not discolor over a long period of time.

In addition, the technical characteristics of the mixed resin solution obtained by mixing toluene or cyclohexanone solvent with a mixture of synthetic resin, butyl crab rubber, resin, and melamine resin, and a small amount of silicone are added to dissolve and dissolve the stearic acid and paraffin. The polymerization resin solution, which was polymerized by mixing the wax solution, was coated on the surface of the earth, and the paste resin, plasticizer, stabilizer, PVC resin, and pigment were coated with the polymerization resin solution as a transfer material (transcription ink) in an appropriate weight ratio. It is characterized in that the transfer film is formed by using a known screen printing method on the upper surface of the earth.

However, such a prior invention also does not use the offset printing method at all, the processing is very low when there is a lot of colors, and it is difficult to print photographs or prints due to the adoption of the screen printing method of the fine print surface There is a limit to the diversity, and therefore the fatal problem that the process operation is relatively extended.

Therefore, Patent Application No. 97-67616 "Permeable Transfer Transfer Method Using Offset Printing" was proposed by the applicant.

According to the above proposal, it is possible to properly solve the above-mentioned problems of the prior patent, but it implies that the visual satisfaction is somewhat lowered because the three-dimensional effect is not given by the formation of a permeable planar two-dimensional printing surface.

Accordingly, an object of the present invention is to attach a transfer coating film closely to the transfer object to be integrated with each other, so that it is possible to give a flexible, soft texture and visual satisfaction at the same time by improving the clarity of color and forming a three-dimensional foamed printing surface. It is in a ship.

In order to achieve the above object, the present invention comprises a first step of screen printing for the treatment of a denitrifier by mixing 90% of ananol, 5% of PVC resin, and 5% of aerosol on the surface of a base paper (deferred paper); A second step of offsetting and screen printing a design of a predetermined shape and color on the surface dried through the natural drying process after the screen printing; A third step of screen printing by mixing DOP 40%, PVC resin 40%, nylon powder 6%, and aerosol 14% on the printing surface, and performing heat treatment at about 170 ° C. to 180 ° C. for 1 minute; A fourth step of screen printing by mixing DOP 30%, PVC resin 30%, nylon powder 10%, aerosol 16%, and foaming agent 14% on the heat-treated surface, and performing heat treatment at about 140 ° C.-150 ° C. for 1 minute; A fifth step of contacting the transferred base paper to the object to be transferred and pressurizing for 5 seconds to 10 seconds with a heat press at about 160 ° C. to 170 ° C. to separate the transfer paper; And a sixth step of pressurizing for 5 seconds to 10 seconds with a heat press of about 160 ° C. to 170 ° C. again through the rear surface of the transfer object after the pressurization process is completed.

The present invention having the above characteristics is clearly confirmed by the specific embodiments of the present invention described below.

1 is a schematic process diagram of the present invention, the embodiment of the present invention according to the process can be divided into six steps.

The first step is the preliminary step of offset and screen printing for the design, which is provided for the degreasing agent treatment on the surface of the paper (die paper), which is especially when the transfer film is separated from each other after a certain time while the surface of the transfer object is pressed. In order to separate easily and naturally from the base paper, 90% of ananone, 5% of PVC resin, and 5% of aerosol are mixed and screen-printed.

Subsequently, a natural evaporation drying process is performed to allow the printing surface to be sufficiently dried in accordance with the screen printing, and then a design such as various figures and characters in a predetermined shape and a desired color is applied to the dried surface of the offset or screen. A second step of printing in a manner is provided.

The third step provided after the second step is mixing and melting 40% of DOP, 40% of PVC resin, 6% of nylon powder, and 14% of aerosol on the printed surface, which has a sophisticated and beautiful design with various shapes and colors. After the screen printing process, and then moved through the primary conveyor system is heat treated for about 1 minute while maintaining about 170 ℃-180 ℃ through a general heat treatment machine.

On the other hand, in order to have a function of the surface reflection (aka, glitter treatment), the printing layer is printed by mixing about 20% of the metallic powder or white powder in the material to be printed in step 3, Due to this, of course, the mixing ratio of the other solvents is set low in reverse order.

Subsequently, in the fourth step, DOP 30%, PVC resin 30%, nylon powder 10%, aerosol 16%, and foaming agent 14% are mixed and melted again on the heat-treated surface, and after this process, the secondary conveyor Through the post-treatment process, which is heat-treated for about 1 minute while maintaining about 140 ℃ -150 ℃ through the system, the corresponding printing surface required by the action of the blowing agent is expressed in a three-dimensional shape.

The base paper transferred through the above process closely adheres to the proper position of the object to be transferred (face, etc.) (the adhesion function between the nylon powder is firmly established), and about 160 ° C After pressurizing for about 5 seconds to 10 seconds using a heat press having a surface temperature of 170 ° C., a fifth step is provided in which the transfer paper is separated so that printed figures or characters can be integrally attached to the transfer object.

At this time, the object to be transferred should be taken into consideration so that the correct printing position can be continuously selected through manual or automated control operations while being supplied in sheets.

By completing the pressurization process as described above, the primary foamed transfer can be completed. In order to further add a three-dimensional effect, the completed transfer object is inverted and then a heat press having a temperature of about 160 ° C. to 170 ° C. again through the rear surface thereof. By providing a sixth step of re-pressurizing for 5 seconds to 10 seconds, it is possible to realize more three-dimensional foaming transfer. To this end, it is possible to prepare a silicone plate having excellent elasticity so that it can be used as a pedestal of the object to be transferred.
