With the steady development of packaging technology and the continuous updating of printing and packaging technology, the packaging box printing production process has been simplified a lot. Now Sunshine Yinyi tells you the specific process:
1.design
Many packaging box designs are designed by companies or customers themselves, or designed by a design company, because design is the first step, what kind of pattern or size, structure, color and so on. Of course, the packaging box printing factory also has services to help customers design.
2.proofing
For the first custom printing packaging box, digital samples are generally required, and the more strict ones even need to be printed on the printing machine, because 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. For the production and production of packaging and printing plants, this is actually the first step. The color craftsmanship of color box packaging boxes is very beautiful now, so the colors of the published editions are also varied, and there are many color boxes. The packaging box not only has 4 basic colors, but also spot colors, such as special red, special blue, black, etc. These are all special 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 choice of color box packaging materials has been determined during the proofing process. Here, let’s talk about the type of paper used in the printing of the packaging box.
1） Single copper paper is also called white cardboard, suitable for color box packaging, single box printing production, general weight: 250-400 grams commonly used.
2） Coated paper: Coated paper is used to make packaging boxes. It is generally used for mounting paper, that is, the coated paper is printed with a pattern, and then mounted on gray board paper or wooden boxes. It is generally suitable for hardcover box packaging production.
3） Whiteboard paper is paper with one side white and one side gray, with white side printed patterns. It is useful as a single box, and some can also be used as a pit-mounted paper box. I will not explain more about the paper here.
5. Printing
The printing process of color box packaging box is very demanding, the most taboo is the color difference, the existence of ink dots, inaccurate needle position overprinting, scratches and other problems, which will also bring troubles to post-press processing.
6. Printing surface treatment
Surface treatment, color box packaging boxes are usually over-glazed glue, over-matt glue, uv, over-varnish, over-matte oil and bronzing.
7.die-cutting
Die-cutting is a more important and final link in the post-press processing process. If it is not done well, the previous effort will be wasted. Pay attention to the indentation against the die-cutting and do not burst the line or die-cutting inaccurately.
8.bonding
Many color box packaging boxes need to be glued together with glue, and some packaging boxes with special structures 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.
