In addition, the adhesive layer 3 is preferably formed so that the sticker 1 can be detached or attached several times.

The base sheet layer 4 formed on the upper surface of the adhesive layer 3 has transparent ink of synthetic resin such as PVC, PET, etc. and is silk-screen printed onto the upper surface of the adhesive layer 3 to protect the adhesive layer 3. In order to prevent the breakage of the color printing layer 7 to be described later upon completion of the manufacture of the sticker 1. In particular, the base sheet layer 4 is formed by applying a PVC SOL transparent ink, which is a mixture of PVC and dioctylphthalate (DOP), to the upper surface of the adhesive layer 3, and curing it by heating. When applied, heated and cured, the base sheet layer 4 has improved elastic strength and opacity, so that the color printing layer 7 described later is clearly printed. Alternatively, the base sheet layer 4 may be formed by mixing a PVC SOL transparent ink and a white ink.

Silk screen printing is made of silk, nylon, Tedron fiber or stainless steel, and the mesh is placed in a frame and the corners are fixed tightly. It is a method that prints only the wire part on the printed matter by blocking the parts (non-fired parts) except for) and presses ink on the net with a squeegee, and it does not depend on various types of ink or dry form or material of the printed matter. There is an advantage that can be printed on the article.

The foamed printing layer formed on the upper surface of the base sheet layer 4 is for three-dimensionally showing the surface of the sticker 1, and foamed ink containing foamed ink or foaming agent is foamed on the upper surface of the base sheet layer 4. After printing, when heated by a heat dryer (not shown) at a predetermined temperature, the coated ink coated portion is concave or convex to protrude to form a three-dimensional surface. The foamed printing layer is formed of a double foamed printing layer which partially protrudes from an upper surface of the base sheet layer 4 through a primary foaming printing process and a secondary foaming printing process. The blowing agent used to form the foam printing layer is azo, bis, isobroti, nitrile or the like which is decomposed by heating to generate gas and is mixed with the foaming ink and then printed on the base sheet layer 4.

The color printing layer formed on the upper surface of the foamed printing layer is for displaying color on the surface of the sticker 1, and the upper surface of the foamed printing layer by UV offset printing using various color inks according to a desired shape and shape. To form.

 The UV offset printing is a method of printing by using the repellency of water and oil, and is provided with a paper feeding unit having a red paper plate for loading the printed paper, a paper discharge unit for discharging the printing paper, and an ink device and a water storage device.
