Description

New printing composition, printing method and apparatus using same

The present invention relates to a novel printing composition, a printing method and a device using the same, and more particularly, for printing that can implement a predetermined pattern on a disc on a printing medium by means of adhesion or transfer without mediating means such as heat or water. A composition, a printing method and apparatus using the same.

In general, printing can be classified into light printing and special printing according to the material on which the printing pattern is implemented, that is, the type of printing medium. The light printing is to implement a predetermined pattern on paper, and the special printing is to designate a predetermined pattern other than paper. Implement on material. Representative examples of special printing include silk screen, real power printing, transfer printing, and the like.

Silk screen is a method of forming a pattern on a screen with a mesh, and by using a squeegee or rubber roller to push the ink through the mesh of the screen to implement a printing pattern on a printing medium such as silk. In this case, besides silk, nylon, tetron and metal screens may be used as the printing medium.

The printing method by silk screen is simple because the equipment is simple and the plate making is cheap. ② It is suitable for small quantity printing. ③ The material of printing media is diverse. ④ The flexibility of the plate makes it possible to print curved surface. There is a large amount of coloring has the advantage of obtaining a strong color print.

On the other hand, there is a disadvantage that ① the quantity of work more than a certain amount must be secured, ② the color expression is limited, ③ the sharpness is low, ④ the loss rate of color and pin is high, and ⑤ the maintenance of finished product is difficult.

In addition, the printing of the wide color method or the chroma color method mainly used for the production of advertising signboards has problems such as high production cost and low resolution.

On the other hand, the transfer printing is a method of engraving the print pattern on the transfer paper, and transfer it back to the printing medium. Decal paper is a laminated paper, such as chrom paper or china paper, a double layered composite, or a sapphire paper laminated with a polyvinyl-based resin coated on top of it. Etc. are used. Welfare is made by attaching rice paper (thin paper) to the ground with grass, drying it, and coating it with special paints (iron, gum arabic, and sodium maltinate) on it.

In the transfer method, a pattern is printed on the transfer paper by a direct printing press, and the pigment (ceramic paint) is dispersed and varnished on the ink just before drying. On the other hand, the quick-dry varnish on the porcelain and paint the rice paper before it dries, the water is applied after removing the rice paper, the pigment is transferred. When the ceramics are baked at a suitable temperature in a kiln (thermal transfer), the pigments are fused. Such transfer printing is mainly used for not only ceramics but also for transfer of bowl type, in this case, printing with ordinary ink, and after the transfer is completed, transparent lacquer is sprayed to protect the transferred pattern. Thermal transfer method as described above is mainly used in the production of stationery, household goods, toys, souvenirs, is a method suitable for low-cost mass production.

However, since printing of complex and precise patterns such as reproduction of advertisements or famous paintings is impossible, there is a disadvantage in that the scope of application is limited.

On the other hand, Japanese Patent Laid-Open No. 52-41682 discloses a water transfer method using water, which accordingly prints a printing pattern on a transfer paper using a paint or a printing ink, and then transfers the transfer paper onto a liquid phase. After floating, pressurizing the transfer medium on the surface of the transfer paper, a method of transferring the print pattern to the transfer medium by the liquid pressure is disclosed. However, since the transfer paper must be removed from the surface of the transfer medium after the transfer is completed, the transfer paper should have good swelling and developability as well as good flexibility and softening property as well as the orbit. However, in the case of floating such a special transfer paper on the surface of the water, the printed pattern printed on the surface is already significantly diffused and deformed before transfer, and thus there is a disadvantage in that a desired pattern cannot be obtained.

To solve this problem, Japanese Patent Laid-Open No. 57-50547 and US Patent No. 4,010,059 disclose a technique in which the film is replaced with a water-soluble film. That is, a predetermined printing pattern is printed on the surface of the water-soluble base (transfer medium), an adhesive is applied on the upper surface thereof, and then floated on the water surface. At this time, the water-soluble base is dissolved in water, and thus, the printing pattern floats on the water surface in a semi-flow state. At this time, the transfer is performed by pressing the transfer medium on the upper half of the printed pattern.

Since the printing method can transfer the curved surface or the irregular surface, it is appropriate to use an object such as a plastic watch case or a TV box as a transfer medium.

However, this water transfer method has a disadvantage that ① only one color printing in one printing process. That is, since the transfer is immediately performed when the transfer medium is in contact with the pattern suspended in the liquid phase, the ink forming the printing pattern should not be in a dry state. Therefore, in order to form a multicolored printing pattern, it is impossible to print using another color ink until the printing ink of the previous step is dry. Also, the printing machine forming the transfer pattern on the transfer medium should be controlled to supply the transfer medium at a speed corresponding to the transfer speed performed in the liquid tank. By the way, since the printing speed in the printing press is generally faster than the transfer speed in the liquid tank, in order to match this with the transfer speed, the printing speed of the printing press is intermittently controlled, which is very difficult. In addition, (3) there is a problem such that the printing pattern is not completely adhered to the transfer medium, or the pattern of the printing pattern is discolored or discolored, resulting in poor color. In addition, the above-described water transfer method has a drawback that only a simple printing pattern can be obtained, since it is virtually impossible to print a beautiful and color-rich shape on a film such as an oblite. In particular, in the case of using a water-insoluble film as a transfer medium, the transfer of the printing pattern to the transfer medium having a complicated curved surface is practically difficult because the presence of the film makes it difficult to transfer the print pattern onto the delicate uneven surface of the transfer medium. impossible. In addition, since the water-insoluble film is to be removed from the transfer medium by physical and chemical means after the transfer is completed, there is a risk that the printing pattern is damaged, and the printing process is complicated.

The present invention is a novel improvement of the above-mentioned disadvantages of the conventional printing method, a novel printing composition which allows the printing pattern on the disc to be directly implemented on the printing medium by applying a simple pressure, without the means of heat or water, etc. It is intended to provide.

The present invention also aims to provide a printing method using the above-described printing composition.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

As a result of numerous experiments, the inventors have discovered a printing composition such that a pattern on a disc can be embodied on a print medium by forming a transfer layer or an adhesive layer between the disc and the print medium.

This printing method is caused by a special chemical action of the transfer layer or adhesive layer, and is performed by applying the printing composition according to the present invention on an original plate, covering the printing medium on top thereof, and applying a predetermined pressure. It is completely different from the conventional printing method using water or water.

[Definition of Terms]

[How to print]

The printing method according to the present invention differs depending on the type of printing ink constituting the printing pattern, the type and thickness of the printing medium, and the like, but is approximately prepared by a disc preparation step (step 1), pretreatment step (step 2) and adhesion or transfer. It can be divided into three stages.

1A to 1D show a printing process according to an embodiment of the present invention, which is a schematic cross-sectional view of a printing process using an original plate having a printing pattern made of toner or an aqueous dye.

[Preparation of Disc]

First, the disk 10 is prepared as shown in FIG. 1A. The printing pattern 10 is formed on the surface of the original plate 10. Offset printing, gravure printing, photographs, oil paintings or watercolors may be used as the disc 10. The material of the disc may be paper, textile paper, photo paper or resin, but most preferably, art paper (surface chemistry). As a treated paper, mainly used as a dedicated paper for offset output).

[Pretreatment Process and Printing Pretreatment Composition]

On the other hand, prior to performing the printing step, it is preferable to perform a pretreatment step to stabilize the surface state of the original. That is, the pretreatment process is performed to prevent the printing pattern 20 on the original from being diffused or detached in the printing process.

In particular, the water-based ink or toner constituting the printing pattern on the paper output has a weak adhesion to the original, unlike oily ink or pigment, and the surface state is unstable such that the dots are dispersed over a large area. There is a fear of pattern deformation due to diffusion.

Therefore, as shown in Figure 1b, by applying the pretreatment composition on the surface of the printing pattern to form the pretreatment layer 30, the empty space between each dot is filled with the pretreatment solution to fix the dot. This prevents the printing ink on the disc from being lifted up and prevents the occurrence of spots or bubbles in the printing process.

However, the pigment, the oil ink, and the like have superior adhesiveness to the original and stability of the pattern compared to the aqueous ink, so that the pretreatment step can be omitted.

In this way, the necessity and the coating thickness of the pretreatment layer 30 are different depending on the type of printing ink and the type of disc, so that the surface state of the disc is detected in advance before the pretreatment step, and as a result, the pretreatment step It is desirable to determine whether to perform. Loupe etc. can be used as a detection apparatus for detecting the surface state of the original plate 10, It is more preferable that the thickness of the pretreatment layer 30 is 20 micrometers-30 micrometers normally.

Printing pretreatment compositions may comprise (i) homopolymers and copolymers of vinyl chloride derivatives; Homopolymers and copolymers of ethyl terephthalate derivatives; Homopolymers and copolymers of acrylate derivatives; And at least one resin selected from the group consisting of homopolymers and copolymers of carbonate derivatives, and (ii) an organic solvent.

The resin is the same as the resin constituting the printing composition, more preferably a mixed resin of poly (vinyl chloride / vinylacetate) and poly (methyl methacrylate), most preferably 443 resin of Union Carbide Corp. Is better to use.

The organic solvent is also the same as constituting the printing composition according to the present invention, and more preferably, a mixed solution of toluene, cyclohexanone and dimethylformamide is used.

In the printing pretreatment composition according to the present invention, the mixing ratio of resin: organic solvent is preferably 1: 1.5 to 10, more preferably from 1: 1 to 15, based on mass.

The coating of the pretreatment composition can be performed by any method that can form a uniform pretreatment layer 30, such as a spraying method using a nozzle, a first coating method with a brush, and a squeeze method, and a dipping method of dipping the disc into the pretreatment solution. Do.

After the pretreatment process is finished, the original plate is dried for a predetermined time and then enters the printing process.

In this case, the drying process depends on the type and size of the transfer medium, but is preferably carried out for 30 minutes to 2 hours at a temperature of 80 ℃ -100 ℃.

[Printing process]

The printing process is basically performed by applying the printing composition to the disc 10 to form the transfer layer 40, as shown in Figure 1d, and then pressing the print medium 50 on the transfer layer.

In the simplest manner, the transfer layer is formed on the original plate by means of a brush or the like, and then a printing medium is placed on the upper portion of the plate, and the upper portion is uniformly pressed by hand. It may be performed by the printing apparatus 100 as shown.

Referring to Figure 4, the printing device 100 is a printing composition supply device for supplying the impression cylinder 160, the plate 170, the disc feeder 130, the print medium supply device 140 and the printing composition It consists of 150.

First, the original plate 10 on which the pretreatment process is completed is supplied from the original plate supply device 130. Subsequently, the printing composition supply device 150, for example, a printing composition is supplied from a nozzle onto the surface of the original plate to form the transfer layer 40. At this time, the thickness of the transfer layer 40 formed on the disc 10 can be adjusted according to the thickness and material of the disc 10 and the printing medium 50, it is usually 20㎛ to 30㎛ is preferred. Thereafter, the disc 10 is transferred to the impression cylinder 160.

On the other hand, the printing medium supply device 140 supplies a printing medium 50 to the plate 170. Print media include acrylate (AC), polyvinyl chloride (PVC), polyethylene terephthalate glycol (PETG), amorphous-polyethylene terephthalate (PET) panaplex, polycarbonate (PC), polyurethane (PU) or polyethylene terephthalate A resin such as PET-Glycol-Amorphousglycol (PET-GAG) is used, and the thickness of the printing medium is preferably 0.1 mm to 10 mm.

By rotating the pressure cylinder 160 and the plate 170 together, the original plate 10 and the printing medium 50 are drawn out in a compressed state with the transfer layer 40 interposed therebetween. At this time, the pressure and the extrusion rate applied to the disc 10 and the transfer medium 50 through the pressure cylinder 160 and the plate 170 is in the thickness and size of the transfer medium, as shown in Table 1 below. In general, it is preferable to extrude at a speed of 50 to 300 rpm under a hydraulic pressure of 2 to 10 Kg. In addition, the thickness of the transfer medium is not limited, but in general, a thickness of 0.1 mm to 10 mm is appropriate.

In this case, T represents a unit of mm / mm, A4 is 21x29.7 (cmxcm) size, A2 42x59.4 (cmxcm) size, A1 is 59.4x84.1 (cmxcm), A0 Represents a size of 84.1x117.4 (cmxcm).

By this process, when the original plate 10 is an art paper, the printing pattern 20 on the original plate 10 is transferred to the transfer medium 50 via the transfer layer 40 under a predetermined pressure, and as a result, Disc 10 is left blank. Therefore, if necessary, only the printing medium may be used after removing the original plate, or the original plate may be attached to the rear surface. In addition, if necessary, by attaching another printing medium in a state where the original is attached to the back of the original with the printing composition interposed therebetween, the original plate 10 is sandwiched between the printing medium 50 in a sandwich form. Can also be used as a state. When removing the original plate 10, in order to increase the sharpness of the printing pattern, it is preferable to perform a separate back treatment such as applying a white paint on the back of the transfer medium.

In addition, when the original plate 10 is a photograph or gravure printed matter, the transfer layer 40 serves as an adhesive layer, whereby the original plate and the printing medium are firmly adhered to each other.

In the above embodiment, the process of supplying the printing composition on the original plate 10 and the process of attaching the printing medium 50 to the upper portion thereof are separately performed, but these processes may be performed at the same time. That is, when one end of the original plate is applied to the pressure cylinder 160 and the printing composition is supplied, the printing process may be performed in such a manner that the printing medium 50 is pressed while pushing the printing composition.

Printing media include acrylate (AC), hard PVC, soft PVC, polyethylene terephthalate glycol (PETG), polyethylene terephthalate (PET), polyethylene terephthalate-glycol-amorphous glycol (PET-Glycol-Amorphousglycol: PET-GAG), Various resins, such as Panaplex, polycarbonate (PC), polyurethane (PU), and the like.

The resulting product obtained by the printing process according to the present invention includes various panels and posters; Billboards such as display or commercial signboards, point of purchase advertisements; Military supplies; Panels for vending machines; Various safety equipments such as game machines, office supplies, helmets; Home appliances; Commercial products using portrait rights of famous characters such as sports, entertainers, cartoon films, and game entertainment; Household goods such as table mats, various trays and fashion tiles; Sporting goods such as soccer balls, volleyball balls, basketball balls, and american football balls; Reproductions or landmarks of various paintings such as famous paintings, torches, oil paintings, and oriental paintings; Various maps and orbits for military, transportation, industrial or educational purposes; Various stickers or emblems used for shoes, hats, bags, clothing accessories, etc .; Design bags and hats for various sports or leisure purposes; Stationery such as system diaries, albums, files, binders, white boards, rulers, pencil cases, etc .; Various props such as computer mouse pads and postcards; And covers for dictionaries, books, and the like.

2A to 2B are schematic diagrams showing a printing process including a pretreatment process as a printing process according to the second embodiment of the present invention.

FIG. 2A illustrates a state in which the printing pattern 20a is implemented by a plate printing technique on the original plate 10a, and FIG. 2B illustrates a state in which a pretreatment solution is injected between the dots of the printing pattern 20a. .

The printing pattern 20a on the original plate 10a obtained by flat printing has a very flexible and soft surface, but on the other hand, the printing pressure is weak and the printing ink has a low degree of transfer, and thus the printed material lacks the force, and the printing strength is low. It has a weak drawback. Therefore, by coating the pretreatment composition for printing according to the present invention on the entire surface of the print pattern 20a to form the pretreatment layer 30a, the printing force of the printing ink can be increased to obtain a print pattern of uniform image quality. Subsequently, the subsequent steps such as applying the printing composition according to the present invention on the pretreatment layer 30a to form a transfer layer are the same as those in the first embodiment.

3A to 3B show a printing process for a printing pattern by an ingravure printing method as a printing process according to a third embodiment of the present invention.

FIG. 3A illustrates a state in which the printing pattern 20b is formed by an ingravure printing technique on the original plate 10b, and FIG. 3B illustrates a state in which the pretreatment layer 30b is formed on the surface of the printing pattern 20b. do.

The print pattern 20a on the original plate 10a obtained by engraver printing is a method in which ink is transferred to a printed object after the line portion has a lower plate surface than the non-line portion and ink is attached to the concave portion. Since the film is formed and the ink adhesion state is relatively stable, the transfer process according to the present invention may be performed without a pretreatment process. However, when the pretreatment layer is formed on the original surface by using the printing pretreatment composition according to the present invention, a soft printing pattern with a more purified color can be obtained. The process after the pretreatment process is the same as in Example 1.

Hereinafter, one preferred experimental example according to the present invention, of course, the present invention is not limited thereto.

Experimental Example 1

(1) Preparation of Pretreatment Composition

First, Union Carbite 443 resin (3.45 kg) was dissolved in toluene solvent (3.6 kg), and then stirred at 120 rpm for 5 minutes. Subsequently, the resultant solution was left to stand for 10 minutes, and cyclohexanone (2.14 kg) was added thereto, followed by stirring at 240 rpm for 5 minutes. After 10 minutes, DMF (2.35 kg) was added and stirred for 10 minutes at a speed of 120 rpm to prepare a pretreatment composition according to the present invention.

(2) Preparation of Printing Composition

First, Union Carbite 443 resin (3.45 kg) was dissolved in toluene solvent (3.6 kg), and then stirred at 120 rpm for 5 minutes. Subsequently, the resultant solution was left to stand for 10 minutes, and cyclohexanone (2.14 kg) was added thereto, followed by stirring at 240 rpm for 5 minutes. After 10 minutes, DMF (2.35 kg) was added and stirred for 10 minutes at a speed of 120 rpm. After about 20 minutes, DOP (225 g) was added to the resultant solution and stirred for 2 minutes at a speed of 120 rpm. According to the printing composition was prepared.

(3) performing the printing process

First, as an original 10, as shown in FIG. 5A, offset printed matter of A0 size was prepared. The material of the disc is art paper.

Subsequently, the pretreatment solution prepared in advance was applied over the entire surface of the original plate 10 to form a pretreatment layer 30 having a thickness of 30 μm, and then dried at 80 ° C. for 30 minutes. The transfer layer 40 having a thickness of 30 μm was formed on the surface of the pretreatment layer 30 using the printing apparatus 100 according to the present invention.

Thereafter, a transfer pattern as shown in FIG. 5B was obtained by covering the PC plate (thickness; 3 mm) of A0 size on the upper portion of the transfer layer 40 and applying 7 kg of hydraulic pressure to compress the same.

As shown in FIGS. 5A and 5B, it can be seen that the sharpness of the pattern implemented on the printing medium (FIG. 5B) is superior to the pattern 5A on the original plate 10, which is a print pattern by a pretreatment process. This is due to the improvement of the halftone characteristic of.

The halftone characteristics when the pattern on the disc (FIG. 5A) and the print medium (FIG. 5B) are observed with loupe are shown in FIGS. 6A and 7A, respectively. As shown in Figs. 6A and 7A, although the post-printing pattern (Fig. 7A) is captured at a low magnification, the halftone is more pronounced than the original pattern 6a before printing captured at a high magnification. This is confirmed again in Figs. 6B and 7B showing the half-point cross sections of the pattern before and after printing, respectively. That is, the post-printing pattern shown in FIG. 7B has not only a small surface area occupied by each dot compared with the pattern before printing (FIG. 6B), but also a sharp state of sharpness even in the vertical distribution of the dot. . As described above, according to the printing process of the present invention, it is possible to obtain a printed pattern having improved sharpness and resolution by further improving the halftone characteristic of the printed pattern.

The same pattern was compared with the wide color 9a and the resultant 9b printed by the printing method according to the present invention.

9B is a result obtained by performing a printing process in the same manner as Experimental Example 1 using a photograph as a disc and using a PC (poly carbonate; thickness 2mm) of A0 size as a printing medium. At this time, the printing composition according to the present invention functions as an adhesive, thereby firmly attaching the original and the printing medium.

9A and 9B, it can be seen that the sharpness of the printed pattern 9b obtained according to the present invention is better.

Experimental Example 4

(1) Preparation of Pretreatment Composition and Printing Composition

A pretreatment composition and a printing composition prepared in the same manner as in Experimental Example 1 were prepared.

(2) printing process

An experiment was conducted to compare the characteristics of the inkjet printout (resolution 600 DPI; Fig. 10A) of which the material is an art paper and the print result (resolution 600 DPI; Fig. 10B) according to the present invention obtained by using this as an original. The printing process according to the present invention was carried out in the same manner as in Experiment 1.

As shown in Figures 10a and 10b, the print pattern (Fig. 10b) obtained by the printing method according to the present invention not only has the same resolution as the original (Fig. 10a), but also shows more improved halftone characteristics than the original. As a result, the sharpness is improved.

The printing composition according to the present invention enables the printing of various patterns such as resin, which is difficult to be used as a printing medium, in particular, by transferring the printing pattern on the disc to the printing medium or forming an adhesive layer between the disc and the printing medium. In addition, it is possible to obtain a result having a resolution and clarity that are difficult to secure by conventional printing techniques.

In addition, since the printing process according to the present invention is carried out by the application of pressure, the process cost is inexpensive, and has the advantage of being suitable for small quantity production of many kinds.
