Description

Printing ink for producing pearl effect and packaging printed by it {PRINTING INK FOR PEARL EFFECT AND A PRINTED MATTER TO UESD THE PRINTING INK}

The present invention differs according to the inherent color and viewing angle of pearl powders on feeders, polyvinyl chloride (PVC) films, polypropylene (PP), polyethylene (PE), etc., using the known silk screen printing technique. It relates to a printing ink for producing a so-called Pearl effect to produce a color and packaging printed matter printed thereby.

In the past, polyvinyl chloride resin was used as the base printing, and the color changed according to the viewing angle, and pearl powder was used with a brush after the base printing described above to form a pearl pattern that produces a sparkling effect. It has been manufacturing wrapping paper or cards by the method of dipping).

Such a manufacturing method is useful for the card without wrinkles, but there is a problem in that the wrapping paper in which wrinkles are generated has a problem that pearl powder (pearl powder) deposited by a brush is continuously detached by wrinkles and needs thorough management during storage movement.

In order to overcome this problem, there is a disadvantage that additional work such as coating and curing with a film on the surface of the coated pearl powder is required.

In order to solve this problem, a pattern printing layer is formed by spraying color paint using 350-420 mesh of silk as a screen plate on the paper by silk screen printing, and then 30-50 trees by silk screen printing. By using a mesh of the screen as a screen plate by spraying a paint composed of 10 to 15% of water pool, 45 to 50% of transparent ink, 25 to 30% of pearl powder and 5 to 10% of binder to form a printed pattern having a pearl pattern It shows how to print the wrapping paper.

However, since the printing method must match the pearl pattern on the pattern printing layer, there is a concern that the pattern printing layer and the pearl powder printing layer may be displaced, and there is a problem that the pearl powder is stuck or peeled off during use and the printing must be performed by multiple steps. .

Kin, because the printing is sprayed on the printed pattern to form a printing layer, there are many printing processes, there is a problem that a bad print is generated because the pattern printing layer and the coating spray layer does not match.

In order to solve this problem, the Republic of Korea Patent Publication No. 2000-30106 (published on June 5, 2000) provides a printing paper printing paint mixed with 500 grams of transparent ink, 500 grams of metallic powder and a binder of 30-50 grams of binder. The present invention proposes a method of printing a wrapping paper by a silk screen printing method.

However, since the transparent ink used in this printing method is made of polyvinyl chloride or acrylonitrile butadiene styrene copolymer resin, the working environment is harmful due to severe odor, and a separate exhaust facility is required, and this is also a metallic color. The powder of eg pearl powder is simply printed on the surface of the paper through a silk screen by a binder, so it is not completely adhered and it does not come out during use.In the case of wrapping paper, there is still a problem of being easily detached due to the wrinkle. .

The present invention was made to solve this problem was possible by maximizing the adhesive efficiency of the transparent ink.

In order to achieve this object, the present invention is composed of SOLUTION VINYL RESIN (UMCH), toluene (TOLUENE), butyl cellosolve (BUTYL CELLOSOLVE), methyl isobutyl carbinol (METHYLISOBUTYLCARBINOL) and CINAR It was possible to print by the usual silk screen printing method using the transparent ink, and the ink for pearl effect printing of this invention which mix | blended appropriately mix | blended this transparent ink and pearl powder.

Hereinafter, the present invention will be described in detail.

SOLUTION VINYL RESIN (UMCH) 28-39%, TOLUENE 54-48%, BUTYL CELLOSOLVE 6-4%, Methylisobutyl carbinol 6-4% and The transparent ink according to the present invention is produced by formulating 6 to 5% of thinner (IPR) and sufficiently stirring them.

In the present invention, the SOLUTION VINYL RESIN (UMCH) is used for the adhesion function and transparency, when the composition is less than 28% in the total composition ratio is mixed with the above transparent ink in the following printing There is a problem that the pearl powder to be peeled off easily from the printing surface, if the composition is more than 39%, the concentration of the transparent ink is turbid, there was a problem that silk screen printing is impossible.

And toluene (TOLUENE) is to be used as a dissolving agent, when the composition is less than 48% in the total composition ratio, there was a problem that the above-mentioned solushon vinyl resin powder is not partially dissolved completely, when the composition to more than 54% Problems affecting the composition ratios of other compositions and complete dissolution without any further composition were uneconomical.

Butyl CELLOSOLVE (BUTYL CELLOSOLVE) is used as a drying retardant. If the composition is more than 6%, pearl powder causes problems in printing completely on the printing surface due to the rapid drying, and the composition is less than 4%. There is a disadvantage in that drying is delayed.

In addition, methyl isobutyl carbinol (METHYLISOBUTYLCARBINOL) is used as an adhesion aid and a dissolution aid after the complete dissolution of the above-mentioned solushon vinyl resin, and when the composition is less than 5%, the problem of poor adhesion and the overall composition is affected. In other words, while it has a disadvantage in that it partially dissolves, the composition of more than 6% is uneconomical.

In addition, thinner (IPR) is also used as a drying delay aid, in which case, if the composition is more than 6%, there is a problem that the pearl powder is completely printed on the printing surface due to the rapid drying, and when the composition is less than 5%, There is a problem that the function as a delay aid is low.

The transparent ink of the present invention prepared by this feature is mixed with the pearl powder is printed by the silk screen printing method. At this time, the transparent ink of the present invention is composed of 70 to 85% and pearl powder 30 to 15% to be used as the ink for printing a pearl effect.

In this case, when the composition of the transparent ink is less than 70%, there is a problem that the pearl powder is stuck or partially detached from the printing surface after silk screen printing, and when the composition is more than 85%, the amount of the pearl powder is used. By lowering the color is changed according to the viewing angle, which is the ultimate purpose, there was a problem of dropping the pearl (pearl) printing effect to produce a sparkling effect.

In addition, in the case of pearl powder, when the composition is more than 30%, the composition ratio of the transparent ink is lowered, so that the pearl powder is released or detached from the printing surface, and the composition below 15% is poor in the printing effect of pearl. There is this.

The ink for pearl effect printing according to the present invention is printed through the silk screen printing technique as described above, which will be described in detail below.

Choose a frame that meets the specifications of the silk substrate, attach a mesh with 150 to 300 necks, and apply a conventional emulsion several times.

After the applied emulsion is completely dried, the film is applied several times again with a thick film, and the film is made with a film to be printed and a thick film-treated frame in a completely dried state, and then mounted on a conventional printing machine.

The printing is completed by using the ink for pearl effect printing according to the present invention in a state where it is mounted on a printing machine, and then the printing is completed through a conventional silk screen printing technique in which a dryer is passed through a dryer and dried.

At this time, the conveyor moves at a feed rate of 10M per minute, the temperature of the belt dryer is usually maintained at 80 ~ 90 ℃.

In particular, when the fabric to be printed is a P.V.C. film, a polypropylene film or a polyethylene film, it is reasonable to maintain the temperature of the dryer at 120 to 140 ° C.

The packaging paper printed using the pearl effect printing ink of the present invention as described above is a problem that the pearl powder does not come out because it is firmly deposited on the printed object, and also used as a wrapping paper that wrinkles occur There was no.

This invention was tried based on the Example.
