Inventory of the most complete printing and packaging process knowledge in history -- common processes of packaging materials

Four-color printing

1. The so-called four colors are cyan (C), magenta (M), yellow (Y) and black (K) inks. All colors can be mixed through these four inks to finally achieve color graphics and text.

2. The most common and common printing, the effect printed on different substrates is different.



Spot printing

1. Spot color printing refers to printing the color with a special ink, which is brighter than the color mixed with four colors. Commonly used are special gold and silver.

2. There are many spot colors. With reference to Pantone color card, spot colors cannot achieve gradient printing, and four-color printing can be added if necessary.


Overgloss adhesive

1. After printing, the transparent plastic film is applied to the printed surface by hot pressing to protect and increase the gloss. The surface is bright, as shown in the figure below.

2. The most basic process for surface treatment of carton. There is a similar gloss, but it can enhance the hardness and tensile properties of the paper.



Overgelatinous

1. After printing, the transparent plastic film is applied to the surface of the printed matter by hot pressing to protect and increase the gloss. The surface is matte, as shown in the figure below.

2. The most basic process of surface treatment of paper box is the same as the varnish, but the glue can enhance the hardness and tensile properties of the paper.

Over UV

1. The prominent part of the printed matter needs to be locally polished and brightened to make the local pattern more three-dimensional.

2. It is printed with the matte glue process, and has no effect when it is printed with the gloss glue.



Hot stamping

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

2. Printing materials include gold, silver, red, green, blue and other colors, but hot stamping can only be monochrome, with a wide variety of colors, but not all colors are available in the market.



Bump

1. Use a set of concave and convex templates corresponding to the yin and yang of the graphics and text, place the substrate between them, and press the embossed concave and convex graphics and text by applying greater pressure.

2. Paper of all thickness can be used, but cardboard can not be convex.
