With the mature development of packaging technology and the continuous update of printing and packaging technology, the packaging box printing production process has also been simplified. Many exposures and films are now gone. The specific process is as follows:

1, Design

Many packaging box designs are designed by companies or customers themselves, or have been designed by a design company, because design is an important step, what kind of pattern or size, structure, color, etc. are desired. Of course, the packaging box printing factory also has services to help customers design.

2, proofing

For the first customized printing packaging box, digital samples are generally required, and the more stringent ones even need to be printed on the printing machine. When the digital samples are printed again, the color of the digital sample may be different during mass printing, and the printing machine Real samples can ensure consistent color in mass production.

3,Publishing

After the proofing is confirmed, it can be mass-produced normally. In fact, this is an important step for the production of packaging and printing plants. The color technology of the color box packaging box is very beautiful, so the published edition color is also varied, many color box packaging boxes There are not only 4 basic colors, but also spot colors, such as special red, special blue, black, etc. These are all spot colors, which are different from the normal four colors. A few colors are just a few PS printing plates, and a spot color is a unique one.

4,paper materials

The selection of color box packaging materials has been determined when proofing, here is the type of paper used for packaging box printing

1. Single copper paper is also called white cardboard, suitable for color box packaging boxes, single box printing production, general weight: 250-400 grams commonly used

2. Coated paper: Coated paper is used as a packaging box, which is generally used for mounting paper, that is, the coated paper is printed with a pattern, and then mounted on gray board paper or a wooden box. It is generally suitable for hardcover box packaging production.

3. Whiteboard paper. Whiteboard paper is a paper with one side white and one side gray, and the white side is printed with patterns. It is useful as a single box, and some are used as a pit-mounted paper box. There is no more explanation about the paper here.

5, printing

The printing process of the color box packaging box is very demanding, the most taboo is the color difference, the ink dots, the needle position inaccurate overprinting, and the scratches, etc., will also bring trouble to the post-press processing.

6, Printing surface treatment

Surface treatment, color box packaging boxes are commonly used as over-varnish, over-matt, uv, over-varnish, over-matt oil and bronzing.

7, die-cutting

Die-cutting molding is also called "beer" in the packaging and printing industry. It is a more important and final link in the post-printing process. If it is not done well, the previous effort will be wasted. Pay attention to the indentation for die-cutting. Don't burst the line, don't die-cutting inaccurately.

8, bonding

Many colorful boxes and packaging boxes need to be glued together with glue, and some special-structured packaging boxes do not need to be glued, such as airplane boxes and sky and earth covers. After bonding, it can be packaged and shipped after passing the quality inspection.
