①What is four-color printing (CMYK)?

      The four colors are cyan (C), magenta (M), yellow (Y), and black (K).

      ②What is spot color printing?

      Spot color printing means that a special ink is used to print the color during printing, which is brighter than the color mixed with four colors. Commonly used are special gold, special silver. There are many spot colors, refer to the Pantone color card, the spot color cannot achieve gradient printing, if necessary, add four-color printing.

      ③What is the glossy glue and the matte glue?

      After printing, a transparent plastic film is applied to the surface of the printed matter by hot pressing to protect and increase the gloss, and the surface is bright. The matte glue is a kind of corresponding to the glossy glue, but the surface highlights the matte.

      ④What is over-UV?

      Partial glazing and brightening are carried out on the parts that need to be highlighted in the printed matter, so that the local pattern has a more three-dimensional effect. This process is printed in conjunction with the process when the matte glue is passed, and this effect does not exist when the glossy glue is used.

      ⑤What is hot stamping?

      Hot stamping is to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metallic luster effect by using the principle of heat transfer.

      ⑥What is bumping?

      A set of concave and convex templates corresponding to the yin and yang of graphics and texts are used, the substrate is placed in between, and the embossed concave-convex graphics are pressed out by applying greater pressure. Embossing can be applied to a variety of paper thicknesses, but not cardboard.

      ⑦What is coding?

      The process of printing logos (production date, shelf life, batch number, company logo, etc.) on the product with the inkjet printer.

      ⑧ What is blister?

      Blister is a kind of transparent material, the main raw material is PVC, PE, or PET.

      ⑨What is OPP bag?

      OPP bags are actually what we know as plastic bags.

      ⑩What is EVA?

      The chemical name is ethylene-vinyl acetate copolymer, and the finished product made of it has the characteristics of good flexibility, shock resistance, slip resistance and strong compression resistance. Used on packaging and inside to secure and protect products. There are a variety of colors to choose from, and the surface can be flocked or wrapped in flannel to enhance the visual effect.

      ⑪What is heat shrinkable bag?

      It is a transparent bag made of a material with strong shrinkage at a certain temperature to protect the packaging.

      ⑫ What is single powder?

      Commonly used carton materials, the thickness of paper ranges from 80g to 400g, and for higher thicknesses, two pairs are required. The paper is glossy on one side and matte on the other, and only the glossy side can be printed. Printing of various colors can be realized, and there is no limit to the color. The commonly used surface treatment processes after printing are: glue, UV, hot stamping, and bumping.

      ⑬ What is pit paper?

      Compared with ordinary paper, it is more straight and has stronger bearing capacity.

      ⑭What is baking paint?

      On the ground to a certain degree of roughness, spray several layers of paint, and bake at high temperature to set. Only solid colors can be used, gradient colors cannot be used.

      ⑮What is silk screen?

      Through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the graphic part to form the same graphic as the original. There are many screen printing colors, but gradient printing is also impossible.

      ⑯ What is pad printing?

      Pad printing refers to a method in which the substrate is an irregular shaped surface, using copper or steel gravure, and casting a hemispherical pad printing head through silicone rubber, which is pressed against the layout to transfer the ink to the substrate to complete transfer printing. In simple terms, pad printing can print small and multi-color overprinted products, and there is no requirement for the shape of the product. Pad printing can achieve many effects that silk screen printing cannot achieve.

      ⑰ What is water transfer printing?

      After the film with special chemical treatment is printed with the desired color pattern, it is sent flat to the surface of the water. When the color pattern is evenly transferred to the surface of the product by the action of water pressure, the coating film is automatically dissolved. After the water is washed and dried, a transparent protective layer is applied.

      ⑱ What is laser?

      A technology for cutting, welding, surface treatment, drilling, micro-machining, etc.

      Packaging and printing is a broad and profound knowledge, and there are still many ways to unde
