Description

Color box manufacturing method {METHOD OF MANUFACUTURE BOX USING COLOR SHEET}

The present invention relates to a method for manufacturing a color box.

There are various conventional wrapping papers, but most of them are those in which a resin such as wax or polyethylene or polypropylene is applied to the printed paper, or a thin film of these resins is laminated, or these resins are sandwiched between the backing paper and the surface paper, etc. .

However, these resins are non-polar and do not have sufficient adhesion strength to paper, so they appear to be sufficiently adhered during treatment. Its value has declined as a wrapping paper for products.

Therefore, in order to increase the glossiness of the wrapping paper using these resins and make it somewhat luxurious, it is necessary to perform special high-grade printing using high-quality paper as a substrate paper, which causes a cost increase and has a problem of peeling off due to low adhesion.

The present invention is to solve the above problems, and since the paint is directly printed on the paper substrate through the screen printing technique, the manufacturing process is simple, and the pattern and the powder forming layer are printed on the first color pattern after printing the powder. This is to provide a method for manufacturing a color box with good texture without performing separate surface coating treatment as there is no problem such as this misalignment and curing at room temperature is possible, and there is no peeling or smearing of the pattern on the metal-colored printed layer.

In addition, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the present invention. Accordingly, the detailed description set forth below is not intended to be taken in a limiting sense, and the scope of the present invention, if properly described, is limited only by the appended claims, along with all scope equivalents as those claimed. Like reference numerals in the drawings refer to the same or similar functions throughout the various aspects.

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

1 is a diagram illustrating a flowchart of a method for manufacturing a color box according to an embodiment of the present invention. Hereinafter, the color box manufacturing method according to an embodiment of the present invention is largely performed in a pre-printing process (S100), a special processing (S200), and a post-processing (S300) process.

In the pre-printing process 300, a color paper (color sheet) is prepared and processing is started by preparing a colored paper (color sheet), although it can emit light due to the coating treatment on general paper or cardboard, but the degree to which the light can be emitted is limited (see step S110).

Using a 350-450 mesh mesh on the colored paper (color sheet) substrate as a screen plate, spray color paint to form a pattern print layer, and then use the screen printing method again using a 30-50 mesh mesh as a screen plate. 10~15% transparent ink, 45~50% pearl powder, 25~30% of powder and 5~10% binder are sprayed to form a pearl pattern printing layer. On the other hand, the binder is preferably used as a visprox TCI 8785 hardener.

In the case of forming a pattern by screen printing using 30 to 50 meshes of the composition as a screen plate, the pearl powder holds each other even if it contains an adhesive material such as water glue. The pearl pattern forming paint does not adhere well to the mesh surface used as a mesh surface, and it is sprayed and adheres to the pattern-printed surface to adhere with excellent adhesion.

Using a paint made of water glue, transparent ink, pearl powder, and binder, a pattern is formed on the pattern printing layer through a screen printing technique. When forming a pattern, if the pattern forming layer becomes too thick, the pattern may be damaged, so it is preferable to form the pattern layer with a thickness of 100 to 125 μm.

It is preferable to use a transparent ink containing polyvinyl chloride or an acrylonitrile-butadiene-styrene copolymer resin as a main component.

It is processed by putting colored paper (color sheet) printed by screen printing into a UV printing machine that prints on aluminum or glass plastic.

After the pre-printing process (S100) process is finished according to the above procedure, the colored paper (color sheet) does not shine as matte according to the processing of the UV printing machine, and it is coated on the printed matter to take advantage of the characteristics of the colored paper (color sheet) Alternatively, special processing (S200), which is an etching process, is performed.

In the special processing (S200) step, a UV coating procedure is performed so that the printed material can emit more light on the printed material (refer to step S210), and an etching process (S220) to provide a three-dimensional effect is performed.

Looking at the detailed operation of UV coating, the UV ink composition includes a coating solution with adhesive performance that is primarily coated on the surface of the packaging material.

The coating solution is composed of a mixture of 65-70% by weight of acrylic emulsion, 29-34% by weight of a mixture of water and ethanol, and 0.5-1% by weight of an antifoaming agent, and the mixing ratio of water and ethanol is 20% water and ethanol It is preferably 80%.

Ink liquid, aluminum powder 15-20% by weight, nitrocellulose resin 10-12% by weight, aldehyde-based resin 10-12% by weight, {propyl acetate (n-Propylacetate), isopropyl alcohol (Isopropylene Alcohol), A mixture of ethanol (Ethanol)} is made by mixing 59 to 64% by weight, and 0.5 to 1% by weight of an antifoaming agent.

The ratio of propyl acetate, isopropyl alcohol, and ethanol is preferably 50%, 30%, and 20%, respectively.

Looking at the etching process, first, using ADVANCE20 photosensitive emulsion from Murakami, Japan, apply the emulsion to the fabric and repeat drying, then expose it to light with a metal lamp for 150 seconds with a plate maker.

After washing with water, the part exposed to light is dried and there is no reaction, and the part not exposed to light is washed with water and flows down. After drying and removing the water, it is coupled to the etching machine (DY-7100).

When printing using etching 150A ink, the part where the oil remains is not printed, but only the part where the oil has been washed off with water, and then passes through a UV dryer (Metal lamp 1, mercury lamp 1, etc.) to dry .

The reason for printing with a screen printing machine is that by repeating application and drying of the emulsion, the thickness is formed as many times as the number of times, so that a three-dimensional effect can be provided when touched by hand.

After the special processing (S200) process is finished according to the procedure, the post-processing (S300) process of manufacturing the packaging box is performed.

The post-processing (S300 process) first proceeds with a lamination procedure (refer to step S310) of thickening the paper by adding corrugated cardboard to the gold and silver paper on which patterns or letters are printed by the above procedure (see step S310). You can lower the price by using

Thereafter, the color cardboard generated by the lamination procedure (S310) is straightened out in the form of a box (see step S320), and the printed matter and the printed matter are fixed and adhered with glue to complete the box (step S330).

The above-described embodiments are for illustration, and those of ordinary skill in the art to which the above-described embodiments pertain can easily transform into other specific forms without changing the technical idea or essential features of the above-described embodiments. you will understand Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive.
