Description

Surface transfer method {METHOD FOR TRANSCRIBING OF SURFACE}

The present invention relates to a method of transferring an image of a printed object to the surface of the object to be transferred, and in particular, regardless of the material or size of the object to be transferred, a high resolution image transfer can be quickly performed with only simple facilities and methods. It's about technology.

In general, manufactured products are printed with images of various shapes on the surface to improve the design.

As such an image transfer method, various methods such as a method of directly printing an ink on a product surface, a gravure printing method, and a heating and pressing transfer method are used.

However, in the existing transfer methods, the applicable target is determined according to the material of the transfer object, so the range of application is not wide and there is a limit to transfer a high-resolution delicate image.

In addition, since it is necessary to have a unique facility applied to the corresponding method, the overall facility scale is complicated and most of them have a hassle to undergo post-processing to prevent damage to the transferred image.

In addition, the existing transfer method has a limitation in that it can be operated in a mass production format because the size and transfer speed of transferable objects are limited.

The present invention has been proposed to solve this problem,

It is intended to provide a surface transfer method that can be operated as a mass production system by reducing the speed of image transfer by increasing the image transfer in a simpler structure and method than the previous one, as well as improving the economic efficiency by simplifying equipment.

In addition, it is intended to provide a surface transfer method that allows an image to be transferred irrespective of the material, mechanical properties, or size of the object to be transferred, so that the application range can be significantly wider than in the past.

In addition, it is intended to provide a surface transfer method capable of minimizing the possibility of damage to an image transferred to a target surface without additional post-processing.

In addition, it is intended to provide a surface transfer method capable of image transfer at a higher resolution than the existing transfer method.

Various embodiments of the present invention for this purpose,

Preparing a print material on which a print layer containing ink is formed, preparing a resin for ink transfer for separating the print layer from the print material, and preparing a transfer object on which the resin for ink transfer is fused to a surface Step, a bonding step in which the surface of the transfer object and the print layer are bonded with the resin for ink transfer interposed therebetween, and the resin for ink transfer penetrates and fuses to the surface of the transfer object and the print layer at the same time, thereby bonding the transfer object and the print material. In the process of separating, the printing layer containing the ink is separated from the printed material in a state fused to the ink-transfer resin and includes an ink moving step to move to the surface of the transfer object.

In the bonding step, a solvent coating process of applying the ink transfer resin to the printing layer before the coating layer and the printing layer are bonded, and the first fusion where the applied ink transfer resin penetrates the printing layer and fuses with the printing layer. The process may include a contact process in which the coating layer and the printing layer are in close contact with each other in a facing state after the first fusion process, and a second fusion process in which the resin for ink transfer penetrates and fuses to the coating layer after the contact process. .

In addition, in the first fusing process, a portion of the resin for ink movement that has penetrated the print layer may surround the ink contained in the print layer.

In addition, the first fusion process and the second fusion process may allow the ink transfer resin to penetrate into the coating layer and the printing layer through micro voids formed in the coating layer and the printing layer.

In addition, the resin for ink movement includes components of the same series as the coating layer and the printing layer, and the first fusion process and the second fusion process are of the same series in the process where the ink transfer resin penetrates the coating layer and the printing layer. The components can be made in a way that is compatible with each other.

In addition, the ink moving step may be performed in a process in which the transfer object passing between the rollers and the printed material are separated from each other after the bonding step.

In addition, the printed material is formed on the base paper and the surface of the base paper, and includes a printing layer, and the printing layer is a solvent component containing ink, an adhesive component for adhering the printing layer to the printed material, and the same material as the ink transfer resin It may be made of a coating component of the mixed form.

The present invention having several such embodiments,

Basically, through the resin for ink transfer, since the ink of the printed material is transferred to the surface of the transferred object simply by bonding the object to be transferred and transferred, the transfer process can be made simple and quick compared to the existing ones, so mass production is possible. .

In addition, this simplifies the facility structure compared to the existing one, so that the transfer process can be easily incorporated into the basic production process of the transfer object, so that the production efficiency of the surface-transferred article is improved.

In addition, since the resin for ink transfer is in the form of tearing off the printed layer from the printed material and taking it to the surface of the transfer object, the ink contained in the printed layer also moves as it is without loss or change along with the printed layer, so it has the advantage of obtaining a high resolution. do.

In addition, because of this method, any material can be image-transferred if the ink-transfer resin can penetrate the material regardless of the material or size of the object to be transferred.

Hereinafter, specific configurations and effects of the present invention will be described based on the contents illustrated in the drawings.

The transfer method according to the present invention is largely as shown in [Fig. 1] transfer object preparation step (S100) and ink transfer resin preparation step (S300), print material preparation step (S200), bonding step (S400), separation step (S500) ).

First, the transfer object preparation step (S100) is a process of preparing an object for transferring an image, and the transfer object includes all materials required for image transfer.

For example, various materials such as iron plate for exterior of household appliances, natural or artificial leather, plastic, wood, plywood, cement block, marble, vinyl, glass, etc. are available, and these transfer objects are prepared before processing the finished product, that is, in the form of rolls or plates do.

At this time, the transfer object 100 may be formed or omitted on the surface of the coating layer 110 depending on the material,

If the object to be transferred is a natural material, a coating layer 110 is formed on the surface, and the coating layer 110 is artificially formed for the transfer process or is basically used for functions such as surface protection of the transfer object 100 regardless of the transfer process. It is used to be formed.

For example, when the object to be transferred is an iron plate for the exterior of a household appliance, a coating layer 110 basically formed on the surface of the iron plate during the production process of the iron plate serves as the coating layer 110.

In addition, when the object to be transferred is natural leather, a waterproof coating is generally applied to the leather surface before being commercialized, and the waterproof coating used serves as the coating layer 110.

For reference, the coating layer 110 formed as described above is formed with micropores so that the resin for ink movement, which will be described later, penetrates into the coating layer 110 through the micropores and can be positioned in an adhesive form on the surface of the coating layer 110.

At this time, the coating layer 110 is made of the same component as the resin for ink movement, which will be described later, so that they can be fused smoothly when they are in contact with each other.

In addition, when the object to be transferred is an organic compound (including a petroleum compound) produced through artificial processing such as plastic or artificial leather, the coating layer may be omitted.

The reason will be described in detail below, but, for example, when the material of the transfer object is a petroleum compound such as plastic, and the resin for ink transfer, which will be described later, is a compound of the same series, when the resin for ink transfer directly contacts the surface, the fusion of each other This is because, in the end, the resin for ink transfer can directly penetrate the surface of the transfer object and obtain a fused effect.

In addition to this, even if the object to be transferred is made of a material other than the resin for ink transfer, such as glass, since micropores are formed in the glass itself, the resin for ink transfer can penetrate into the glass through the pores.

In addition, it is because the adhesion efficiency with the resin for ink transfer can be further improved when a scratch-type processing is performed on the glass surface.

That is, the transfer object may be applied as long as it has a penetration surface through which a coating layer may be selectively formed on the surface depending on the material and the like, and even if the coating layer is omitted, the resin for ink transfer may penetrate.

The transfer object 100 thus prepared is prepared in a rolled state as shown in [FIG. 2] or in a stacked form.

When the object to be transferred is prepared in this way, a print material preparation step (S200) is performed.

The print preparation step (S200) is a process of preparing a print in a state in which an image required for the transfer process is first printed, wherein the print 200 used is basically a variety of printing methods on the surface of the base 210 on which the printed image is printed. It consists of a structure in which an image is printed.

Specifically, the printed material 200 is largely divided into the original paper 210 and the printed layer 220 as shown in FIG. 4,

The base 210 is a material capable of printing and other coating processes on the surface, such as a film of paper or other synthetic resin material.

In addition, the printing layer 220 serves to move ink by reacting with the resin 300 for moving ink, which will be described later in the process of transferring to the surface of a transfer object, while retaining the ink of the image to be printed on the original paper. It consists of a structure in which the ink receiving component 222, the adhesive component 224, the coating component 226, and the peeling component 228 are mixed.
These components are applied in the form of particles so that a void is formed between each particle so that ink is positioned in each void.
In addition, by mixing a water-resistant resin (not shown) with the ink-receiving component 222, the ink 500 is easily fixed in each pore, as well as having water resistance, thereby preventing ink bleeding.

The ink-receiving component 222 used at this time functions to hold the ink 500 of the printed image and contains components such as silica, clay, talc, and calcium carbonate. Mixed or optionally applied.

These pigment components are applied in a particle form of about 2 µm to 10 µm so that a void is formed between each particle so that ink is positioned in each gap.

In addition, by mixing a water-resistant resin (not shown) with the ink-receiving component 222, the ink 500 is easily fixed in each pore, as well as having water resistance, thereby preventing ink bleeding.

In addition, the adhesive component 224 serves to maintain the stable formation of the printed image by keeping the above ink-receiving component 222 attached to the surface of the base 210, carboxymethylcellulose, polyvinyl alcohol ( Polyvinyl alcohol), latex, acrylic, and other ingredients are used.

In addition, the coating component (3) serves to prevent smearing of the ink and to protect the base 210 from moisture, and the same material as the resin for ink transfer may be used.

In addition, the peeling component 228 allows the printing layer 220 to be smoothly separated from the base paper during the transfer process, and wax, fluorine, or other silicone-based components are used.

For reference, the printing layer 220, like the ink-receiving component 222 mentioned above, is formed with a micro void as a whole, so that the resin 300 for moving ink, which will be described later, can penetrate into the printing layer 220 through the void.

delete

When the image is printed on the printed material 200 by the above-described structure, the ink of the image is not printed directly on the surface of the original paper, but the ink is printed in a state filled in each void of the printing layer 220, so that the original paper 210 It is exposed on the surface.

For reference, the image printing of prints can be selected from printing methods that can be mass-produced, that is, high-resolution methods such as roto printing, gravure printing, and digital printing.

The prepared print 200 is wound in a roll shape like the transfer object 100 as shown in [FIG. 2] and is prepared in a structure that can be moved while one end is released along a certain path.

Of course, it can be prepared in a stacked state, not in a roll form.

When the preparation of the printed material 200 is completed, a solvent preparation step (S300) is performed.

The solvent preparation step (S300) is a process of preparing the ink transfer resin 300 for moving the printing layer 220 and the ink 500 of the printed material 200 to the object to be transferred 100 in the transfer process,

At this time, the resin 300 for ink transfer is largely composed of a main solvent 310, a diluent 320, and a viscous agent 330 as shown in FIG.

Among them, the main solvent 310 plays a practical role of moving the printing layer 220 and the ink of the printed object 200 to the surface of the transferred object 100 during the transfer process, and the coating layer 110 of the transferred object 100 and The same or similar material as the coating component 226 in the printed layer of the printed material is used.

That is, when the material of the coating layer 110 is polyvinyl chloride (PVC), the main solvent 310 and the coating component 226 are also made of polyvinyl chloride.

In addition, if the coating layer 110 of the transfer object 100 is polyurethane (POLYURETHANE), the main solvent is also applied as polyurethane.

The reason for forming the same material for the coating layer 110, the main solvent 310, and the coating component 226 is that the materials of the same component have high compatibility and adhesion with each other, and detailed description will be made below. .

Of course, the components of the main solvent 310, the coating layer 110, and the printing layer 220 are not necessarily the same, and it is irrelevant even if the components are mutually wrong as long as they are organic components that are mutually compatible and fused upon contact.

In addition, if the coating layer 110 is not formed, if the material to be transferred 100 itself is the same or a similar component to the ink transfer resin, direct fusion between the transfer object and the resin for ink transfer is achieved.

Even if the object to be transferred is a material that cannot be directly fused with the resin for ink transfer, such as glass, the resin for ink transfer may be fused in such a way that it penetrates through the micropores of the glass itself.

For reference, in the case of a product having a low microporosity, such as tempered glass, as described above, a process such as a scratch form is performed on the surface so that the adhesive force of the resin for ink transfer is maximized.

Another component constituting the resin 300 for ink transfer together with the main solvent 310, the diluent 320 induces dilution of the main solvent 310, thereby coating the main solvent 310 and the coating layer of the transfer object 100 ( 110) and the coating component of the printed material 226 serves to help the fusion.

As a diluent, ethylbenzene, methyl ethyl ketone (MEK), and ecosolben are used. In addition, a solvent such as formide, tetrahydrofuran (THF), and ethyl acetate (EA) is added to increase the dissolution efficiency between the diluent and the main solvent. It can also be used as

In addition, the viscous agent, another element constituting the resin for ink transfer, imparts an appropriate viscosity of each component constituting the resin for ink transfer so that the resin for ink transfer can be used in a liquid state, and at the same time, the resin for ink transfer and the coating layer 110 And it serves to ensure the appropriate adhesion between the print layer 220.

As such a viscous agent, bisphthalide or ethyl cellulose is used.

For reference, diluents, solubilizers, and viscous agents other than the main solvent are not limited to the above-mentioned components, but can be selected and used among other components having the same function, and are used within a range that does not adversely affect the environment or the human body. .

When the resin 300 for ink transfer is prepared through the above process, a bonding step (S400) is performed.

The bonding step (S400) is a process in which a substantial transfer process is performed, and is further divided into a solvent application process (S410), a primary fusion process (S420), an adhesion process (S430), and a secondary fusion process (S440).

Among them, the solvent application process (S410) is a process of applying the resin 300 for ink movement on the surface of the printed layer 220 of the printed material 200, and the printed material 200 prepared in the form of a roll or plate as shown in FIG. ) Is a method in which the resin 300 for moving the ink is placed on the printing layer 220 of the section that is released and moved in the unwinding state and is applied on the printing layer using the application roller 5.

Since the resin 300 for ink movement applied in this way is the same material as the coating component 226 of the printing layer 220 and micropores are formed in the printing layer, it penetrates into the printing layer 220 through the micropores simultaneously with application. A primary fusion process (S420) in which the main solvent 310 is fusion-bonded with the coating component 226 is performed.

In this process, the resin 300 for moving ink penetrated into the printing layer 220 surrounds the ink 500 inside the printing layer 220, and the ink has a structure like a capsule.

Then, the adhesion process (S430) performed thereafter is a process of laminating and pressing the printed object 200 and the transfer object 100, and as shown in FIG. 2, the transfer object 100 and the primary fusion process (S420). As the printed material 200 passed through is released from the roll state, the first and second rollers 1 and 2 rotating in a mutually opposite state while moving along a predetermined path are simultaneously passed.

Therefore, the coating layer 110 of the transfer object 100 passes through the first and second rollers 1 and 2 in a state of being closely laminated to the printing layer 220 of the printed object.

In this process, the transfer object 100 and the printed object 200 laminated are slightly compressed by the first and second rollers 1 and 2.

Accordingly, the secondary fusion process (S440) in which the upper section of the resin for ink transfer 300 penetrates into the printing layer 220 through the micropores of the coating layer 110 and the main component and the coating component are mutually fusion-bonded.

Due to this, as the ink transfer resin 300 is partially fused with the printing layer 220 of the printed material 200 and partially remaining also penetrates into the coating layer 110 of the transfer object 100 and is secondarily fused, The printing layer 220 is integrated with the coating layer 110 through the ink transfer resin 300.

In this process, a part of the ink moving resin 300 surrounding the ink also moves to the coating layer 110 as shown in FIG. 6 and is fused with the coating layer 110. That is, the ink inside the printing layer as well as the coating layer are all integrated with the coating layer 110 through the resin for ink movement.

For reference, as mentioned above, when the material of the transfer object 100 is a material that can be directly fused with the resin for ink transfer, the ink transfer resin is directly infiltrated into the surface of the transfer object.

When the bonding step (S400) is completed, a separation step (S500) is performed.

The separating step (S500) is a process of actually moving the ink including the print layer of the print 200 to the coating layer 110 of the transfer object 100,

In the state of passing through the second fusion process (S440), the transfer object 100 is pulled and wound by a separate first winding roller 3 as shown in [FIG. 2] and [FIG. 7], and the printed material 200 is a second winding roller. It is pulled and wound by (4).

Due to this, the transfer object 100 and the printed material 200 that have passed through the first and second rollers 1 and 2 in a stacked state are separated from each other.

In this separation process, the printed layer 220 of the printed material 200 is separated from the original paper 210 by the adhesion force with the resin 300 for ink transfer and the peeling component 228 contained in the printed layer, so that the transferred object 100 The coating layer 110 is moved onto the surface.

At this time, since the printing layer 220 contains the ink 500 of the transfer image, as the print layer 220 eventually moves to the surface of the transfer object 100, the image of the print 200 is also transferred. Is moved to the surface.

Therefore, the printed material 200 separated from the transfer object 100 remains only the original paper 210 and is printed on the original paper 210 on the surface of the coating layer 110 of the transfer object 100 wound on the first winding roller 3. The image of the print layer 220 was in a transferred state.

As described above, the non-heating surface transfer method of the present invention is a concept in which the resin for ink transfer tears off the printed layer on the printed object and takes it to the surface of the transfer object as it is separated after the bonding between the print and the transfer object is made with the resin for ink transfer therebetween.

For reference, in the process of transferring the object 100 to the first winding roller 3, a separate sheet (not shown) is wound while being laminated on the surface of the coating layer 110, so the image of the surface of the coating layer 110 is The phenomenon of being buried in the other section of the transfer object is prevented.

As described above, since the image transfer can be performed using only the welding principle between the transfer object and the resin for ink transfer, the transfer object can be easily transferred without restriction on material or size.

In addition, it is economical because the size of equipment is much simpler than other transfer methods because it simply passes through the bonding and separation process between the transfer object and the printed object with the resin for ink transfer between them.

In addition, this makes it easy to incorporate the transfer process of the present invention into the basic production process of the transfer object, and finally, it is possible to obtain an effect capable of mass production.

In addition, since the present invention is a method of tearing off the ink of a print and moving it to a transfer object, there is no fear of loss or deformation of ink in the transfer process, so that a high resolution can be obtained.

For reference, a third coating layer using a UV coating agent or the like may be formed on the surface of the second coating layer, if necessary, while the image is transferred onto the coating layer 110 of the transfer object 100 to prevent damage to the image.

The coating layer 110 is formed on the surface of the transfer object 100 that has undergone all the transfer processes, and the printing layer 220 of the print containing the ink and the resin 300 for ink transfer are simultaneously fused on the surface of the coating layer 110. It has a structure formed in a state.

The present invention described above can be implemented in various modifications and combinations by those skilled in the art, but such modifications and combinations are not limited to the above-described embodiments and are included in the technical scope of the claims described below. It should be judged as belonging.
