Description

Method for manufacturing a anti-counterfeiting thermal transfer film using a gravure printing roll and the anti-counterfeiting gravure thermal transfer film produced thereby TECHNICAL FIELD

The present invention relates to an anti-counterfeiting gravure thermal transfer film manufacturing method using a gravure printing roll, and to the anti-counterfeiting gravure thermal transfer film prepared thereby, and more specifically, to print black and white images and colors such as text, text, etc. The present invention relates to a forgery prevention gravure thermal transfer film manufacturing method and a forgery prevention gravure thermal transfer film produced by treating a gravure thermal transfer film with an anti-counterfeiting treatment agent to prevent forgery and tampering.

In general, a method of printing on a substrate such as an apparel fabric, a film, or the like by thermal transfer printing, first prints a picture on a substrate on which a release layer is formed, applies a heating adhesive to the printed substrate, and then when the heating adhesive is dried, the substrate It was a heat transfer method to heat-press the surface printed on the fabric to the fabric to adhere the planar thermal transfer to the fabric.

With the recent increase in the amount of personal information, there is a tendency to record necessary information on plastic cards, for example, identification cards, credit cards, communication cards and the like. On the other hand, personal information records are mainly printed with letters or barcodes or with images in some cases.

The thermal transfer method as described above generally includes a heat resistant layer on one side of the substrate such as polyethylene terephthalate (PET) film to prevent thermal fusion of the substrate and the thermal transfer head, and on the other side opposite thereto. It is configured to include a hot melt ink layer or a sublimation dye layer and a hot melt ink layer.

On the other hand, the thermal transfer printing method is widely applied to outdoor small-scale advertising media, commercial prints such as election posters, stickers, brochures, calendars, as well as label printing of food, medicine, paint, business cards, identification cards, and the like.

However, the conventional transfer paper manufacturing method, such as the thermal transfer method has a problem that the film and the print shape is inferior in adhesion and due to the generation of bubbles, the pattern or shape is not clearly transferred when transferred.

An object of the present invention is a method of manufacturing a gravure thermal transfer film for anti-counterfeit to prevent the forgery of the printed pattern or shape, and the thermal transfer printing of the pattern or shape clearly on the surface of the iron plate, plastic, aluminum, MDF, etc. It is to provide an anti-counterfeiting gravure thermal transfer film produced by.

An object as described above, the step of applying a release treatment agent to the film disc; Printing a pattern or a shape using an aqueous or oily ink on a film disc to which a release treatment agent is applied; An anti-counterfeiting step of performing an anti-counterfeiting process on a specific portion printed to prevent forgery of the article; And drying by applying an adhesive to a film disc, wherein the steps are performed by a method for producing an anti-counterfeiting gravure thermal transfer film according to the present invention, which is performed using a gravure roll, and the anti-counterfeiting gravure thermal transfer film produced thereby. Can be achieved.

In the above, the anti-counterfeiting treatment step is performed at the same time as the printing step, the anti-counterfeiting treatment agent can be printed mixed with a small amount in an aqueous or oil-based ink, or forged in a portion of the printed pattern or shape after one color is printed. After the anti-treatment agent has been processed, it may proceed in such a way that a new color is printed, or part of the printed pattern or shape may be processed after the final color has been printed.

According to the method of manufacturing a gravure thermal transfer film for anti-counterfeit using a gravure printing roll according to the present invention as described above, the film disc and the pattern so as to clearly transfer the pattern or shape to the surface evenly selected, such as iron plate, plastic, aluminum, MDF While adhesion of the shape is improved, counterfeiting and tampering can be prevented.

For what reason have you been manufacturing thermal transfer films without gravure printing rolls?

According to the present invention, the anti-counterfeiting gravure thermal transfer film manufacturing method using a gravure printing roll first using a gravure printing roll of a paraffin wax-based release agent that can be removed by heating on the bottom of the film disc with a paper or a synthetic resin film, etc. To apply.

In this way, when the release agent is applied to the film original, various patterns or shapes are printed on the film original coated with the release agent by a gravure printing method using oil-based or aqueous ink mixed with pigments using a gravure roll.

When printed on film negatives, it can be printed in multiple colors (printing at least 1 degree). After the pattern or shape is printed on the film disc, an oil-based or water-based ink in which an anti-counterfeit treatment agent of an acrylic resin-based or melatin-based resin-based mixed with a pigment is added to a specific portion printed to prevent forgery of the article according to the present invention. Is printed.

The anti-counterfeiting treatment step may be carried out by applying the anti-counterfeiting treatment agent (drug) alone or by mixing a small amount with an aqueous or oily ink used for printing. Such a small amount of the anti-counterfeiting agent is added because the anti-counterfeiting agent (drug) is relatively expensive, and therefore, the area where the anti-counterfeiting agent is printed is also treated to a relatively specific part of the design or shape, for example, It may be limited to certain parts, such as eyes.

Alternatively, the anti-counterfeiting treatment step may be performed when the pattern or shape has a plurality of colors (1 degree or more colors), and after one color is printed, the anti-counterfeiting agent (medicine) on a part of the printed pattern or shape. May be processed and then proceeded in such a way that a new color is printed, or processed to be printed on a particular portion of the printed pattern or shape after the final color of the pattern or shape has been printed.

As noted above, if a pattern or shape is printed on the film disc in multiple colors (more than one degree of color) and the anti-counterfeiting agent is treated for a particular portion of the pattern or shape, the film disc may alternatively be Only the shapes or shapes formed in the aluminum can be deposited and cleaned. By such aluminum deposition, the pattern or shape printed on the film master becomes clearer.

If aluminum is deposited in the printed pattern or shape as described above, the primer may be applied again as an intermediate medium after washing. Such primers may differ from the primers described above and are intended to reinforce the adhesion of the deposition surface and the adhesive applied subsequently. Such primers may be commercially available for gravure printing, consisting of a mixture of resin and adhesive and used as intermediate adhesive.

Such primers may be used according to the type of material to which the hydrocarbon-based adhesive which is subsequently applied on the film disc is to be transferred or patterned, that is, such as PP, ABS, PE, PS resin, iron plate, or PET. For example, in the case of an iron plate, since an additive such as a bond-based additive may be added, it functions to improve the adhesiveness of such an adhesive.

As described above, when the adhesive is applied to the surface on which the pattern or shape of the film disc is printed and dried, the thermal transfer film adheres to the surface of the object such as PP, ABS, PE, PS resin, iron plate, or PET. Thus, a pattern or a shape can be transferred by thermal transfer.

As can be seen from the above, the anti-counterfeiting gravure thermal transfer film production method according to the invention the entire process step is carried out using a gravure printing roll.

1 is a flow chart showing the process of the anti-counterfeit gravure transfer paper manufacturing method according to the present invention.
