Description

Sublimation transcription ink for computer and manufacturing method thereof

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sublimation transfer ink for a computer, and more particularly, to a sublimation transfer ink for a computer which enables a transfer output through a plain paper using a computer (for example, a personal computer) And a manufacturing method thereof.

[0002] In general, a transcription method, which is one of methods for forming a flower shape or various kinds of noises on the surface of clothes or various products, is used. In this transfer method, when the transfer paper is brought into close contact with a transfer object (for example, clothing, plastic, etc.) and heat is applied thereto, the pattern printed on the transfer paper is transferred to the transfer object to form a pattern on the transfer object.

BACKGROUND ART [0002] Conventionally, transfer methods for manufacturing a transfer paper include an offset type, a gravure type, and a screen type.

The following is a brief description of the process of making the transfer paper by the offset transfer method. For example, in order to produce a transfer sheet of a robot figure, a first step of photographing a manuscript (i.e., photographing a robot), a second step of developing a photographed robot, a third step of editing the film, A fourth step of coating and plate-making, a fifth step of developing the film obtained in the fourth step, a sixth step of drying the developed film, a seventh step of applying the dried film to light, Burning: burning) Step 8 → Step 9 of printing a film on a sheet of paper → Step 10 of printing this on a sheet of paper to complete a transfer sheet.

In the next gravure transfer method, a first step of photographing a manuscript (for example, a robot), a second step of developing a photographed robot, a third step of editing a film, a fourth step of applying a sensitizing solution to the film, A fifth step of developing the copper plate obtained in the fourth step, a sixth step of drying the developed copper plate, a seventh step of corroding the dried copper plate, an eighth step of color-printing the copper plate, And a ninth step of completing the ninth step.

Finally, in the screen method, a first step of photographing a manuscript (robot, for example), a second step of developing a photographed robot, a third step of editing the film, a fourth step of producing a screen frame, A sixth step of applying the emulsion light to the screen, a seventh step of applying light, an eighth step of developing the screen, a ninth step of drying the screen, a tenth step of color-printing the screen, And then printing this on a sheet of paper to complete a transfer sheet.

The transfer methods of the above-described three conventional methods have the following problems.

First, all of the above three methods require a lot of manufacturing time and manpower, a large production cost, and a large manufacturing cost because a transfer sheet is manufactured through a lot of manufacturing steps (processes).

Second, all of the above three methods require a day or more (for example, about 2 to 3 days) because a small amount or a sample of a transfer paper is manufactured through a number of steps. As a result, samples can not be produced on the spot, and therefore they have difficulties in responding to customer's needs and have many difficulties (for example, export counseling, sample orders, etc.).

Third, since all of the above three methods are processed by solvents and chemicals in the manufacturing process, they cause pollution of water quality and atmosphere by discharging wastewater, and also cause problems of respiratory disorder and industrial safety due to use of solvent .

Fourth, all of the above three methods require a time-consuming manufacturing time because color printing of the transfer paper is necessarily performed during the manufacturing process.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and its object is to provide an image forming apparatus capable of transfer printing on plain paper by using a computer and an electro- To reduce manufacturing time of transfer paper, to prevent industrial safety and pollution by omitting the use of solvents and chemicals, to transfer four primary colors at the same time, and to reduce labor and production costs accordingly. Transfer ink and a manufacturing method thereof.

In order to achieve the above object, the present invention provides an ink composition comprising a sublimable dye (disperse dye) and a pigment in an amount of 10-20%, distilled water 60-75%, aqueous preservative 2-5%, surfactant 2-5% -6% of a lubricant, 2-3% of a lubricant, 1-2% of a dispersant, and 2-5% of a defoamer.

The above sublimation transfer ink is prepared by adding 2-5 vol% of an aqueous preservative as an additive, 2-5 vol% of a surfactant, 3-6 vol% of an aqueous adhesive, 2-3 vol% of a lubricant, % Of the antifoaming agent, and 2-5 vol% of the antifoaming agent are mixed and dissolved in a blender; Step 2: mixing and dissolving the sublimable dye and the pigment in an amount of 10-20 vol% in the material obtained in the step 1; A step 3 in which the material obtained in the step 2 is evenly mixed and rolled so as to be well dispersed; Adding 45 to 55% of the remaining distilled water to the material obtained in the step 3 and mixing; Characterized in that it is produced by step 5 of filtering impurities of the material obtained in step 4 above.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The sublimation transfer ink for computer of the present invention contains sublimable dye (disperse dye) and pigment 10-20%, distilled water 60-75%, aqueous preservative 2-5%, surfactant 2-5%, aqueous adhesive 3- 6% of lubricant, 2-3% of lubricant, 1-2% of dispersant, and 2-5% of antifoaming agent.

As the sublimable dyes and pigments, cyan Dianix Blue AC-E, Magenta Dianix Blue AC-E, Yellow Dianix Red AC-E and Black Dianix Black are used.

As a lubricant, ethylene glycol, N-methyl 2-pyrrolidone as a lubricant, and Focelle as a preservative as a preservative, EDTA as an oxygen absorbing agent as a surfactant, CMC as a viscosity-imparting agent as an aqueous adhesive, Use girI.

The reason why the composition range of the sublimable dye and the pigment is limited to 10-20% is as follows. If the dye is less than 10%, the color is thinned and the desired color And if it is 20% or more, the color becomes turbid and the printability becomes poor, so that the ink is not easily sprayed.

The reason why the composition range of the distilled water is limited to 60-75% is that when the distilled water is 60% or less, the viscosity of the additive becomes higher due to the solid content of the additive, Spraying is well done but the colors of the dyes and pigments are getting thinner and the desired color can not be obtained.

The reason for limiting the composition range of the aqueous preservative to 2-5% is that if the aqueous preservative is less than 2%, the preservative effect is lowered. If the aqueous preservative is more than 5%, the property is badly affected.

The reason for limiting the composition range of the surfactant to 2-5% is that if the surfactant is 2% or less, the original function of the surfactant is not exhibited well, and if it is 5% or more, It will have a bad influence.

The reason why the composition range of the aqueous adhesive is limited to 3-6% is that if the water-based adhesive is 3% or less, the adhesive strength of the dye is lowered, and if it is 6% or more, the adhesive strength is good. However, do.

The reason for limiting the composition range of the lubricant to 2-3% is that the lubricant serves as an accelerator for accelerating the thermal spraying. When the lubricant is less than 2%, the injection effect is lowered. When the lubricant is more than 3% It does not increase.

The reason for limiting the composition range of the dispersant to 1-2% is that if the dispersant is 1% or less, the additive is not completely dispersed, and if it is 2% or more, the dispersing effect is not further increased.

When the defoaming agent content is 2% or less, the defoaming action is weak and bubbles can be generated. When the defoaming agent content is 5% or more, Which is a cause of lowering the adhesive strength of the adhesive layer.

The sublimation transfer ink for a computer formed as described above is prepared by the following method.

First, 2-5vol% of an aqueous preservative, 2-5vol% of a surfactant, 3-6vol% of an aqueous adhesive, 2-3vol% of a lubricant, 1-2vol% of a dispersing agent and 2-5vol% of an antifoaming agent were added to 15-20vol% And the mixture was mixed so that the additive was dissolved by distilled water. Then, 10 to 20% by volume of a sublimable dye and a pigment were added to the mixed material so as to dissolve the mixture, and then the mixture was dispersed evenly After the roller is rolled, the remaining material is mixed with 45-55 vol% of distilled water, and the resulting material is filtered through a precision filter several times to completely remove dust and impurities, thereby completing the manufacture of sublimation transfer ink do.

The sublimation transfer ink for computer manufactured as described above is packaged in a container in a dust-proof state and is injected into a printer cartridge through an injector (using pneumatic pressure) to produce a product.

The process of making the transfer paper using the sublimation transfer ink for computer according to the present invention is as follows.

First, a cartridge containing a sublimation transfer ink is mounted on a printer, and then a desired document (e.g., characters, patterns, real objects, photographs, etc.) is input / edited on a computer and output to a printer. So that the desired transfer paper is produced.

The transfer sheet thus prepared is transferred to a transfer object (for example, clothes, plastic, aluminum, coating film, film, nonwoven fabric, etc.), and the transfer method to the transfer object is performed by various methods as follows .

First, it is printed on a computer and the completed transfer paper is brought into close contact with the subject. ① The method of transferring to a transfer object by heating at 180-200 ℃ for 10-15 seconds by using a flat plate type hot plate, ② Using a electric oven, 180 -2 ° C for 10-15 seconds to complete the transfer to the object to be transferred, 3) a method of transferring to the object by heating the object at 180-250 ° C for 30-50 seconds using a conveyor type electric oven, And a continuous operation method in which the transfer is completed on a transfer object by heating the transfer sheet at 180-200 ° C. for 10-20 seconds using a rotary type transfer plate conveyor. The heating temperature and the heating time of the transfer paper may vary depending on the material of the transfer object.

The sublimation transfer ink for computer produced as described above has the following advantages.

First, a manuscript is input and edited using a computer and output to a printer, whereby a transfer sheet is manufactured, and the time for manufacturing the transfer sheet is instantaneously performed. Accordingly, the sample transfer paper can be manufactured quickly, and the effect of the customer convenience can be obtained, thereby greatly reducing the production cost.

Second, since the transfer paper is not processed as in the prior art, it can be used as plain paper (for example, imitation paper, imitation paper, Norouji, etc.) without any restriction on the paper selection. As a result, the use of transfer paper is convenient and the material cost can be reduced.

Third, the four primary colors are simultaneously processed at the time of making the transfer paper, so that it is not necessary to print each color at the time of manufacturing the transfer paper as in the conventional method, thereby saving much time.

Fourth, since solvents and chemicals are not used at all during the process of manufacturing the transfer paper as in the past, it contributes to industrial safety and pollution prevention.

As described above, according to the sublimation transfer ink for a computer and the method of manufacturing the same according to the present invention, since a transfer sheet is manufactured by a very simple method, it is possible to manufacture an unskilled person, and the time and labor cost are greatly reduced, It is very inexpensive and has an effect of greatly contributing to enhancement of competitiveness.
