With the steady development of packaging technology and the continuous updating of printing and packaging technology, the printing process of packaging boxes has been simplified a lot. Now Sunshine Printing Post tells you the specific process:
Many packaging boxes are designed by enterprises or customers themselves or by design companies, because design is the first step, what kind of design or size, what structure, color and so on. Of course, packaging printing plants also have services to help customers design.
For the first time customized printing boxes, it is generally necessary to make digital samples. Stricter ones even need to be solidified by the printing press, because when making digital samples again, the color of digital samples may be different from that of digital samples in mass printing, and the solidified samples of the printing press can ensure that the color of mass production remains the same.
After the proofing is confirmed, the normal production can be carried out in batches. In fact, this is the first step for the production of packaging and printing factories. Now the color technology of color box is very beautiful, so the color of the published edition is also varied. Many color box boxes not only have four basic colors, but also special colors, such as magenta and magenta. Blue, black and so on are all spot colors, which are different from the normal four colors. Several colours are PS printing plates, and spot colours are unique ones.
The choice of packaging materials for color boxes has been determined when proofing. Here we talk about the types of paper used for printing and making packaging boxes.
Single copper paper, also known as white cardboard, is suitable for color box packing boxes, single box printing and production, and the general weight is: 250-400 grams commonly used.
Copper plate paper is packaged with copperplate paper, which is generally used as mounting paper, that is, copperplate paper printed patterns, and then mounted on gray board or wooden boxes, generally suitable for hardbound box packaging.
White board is a white, gray paper, white printing patterns, useful for single boxes, and some used for crater boxes, here we do not make more explanations for paper.
The printing process of color box packaging boxes is very demanding. The most taboo is color difference, ink dot, imprecise needle position overprinting, scratch and other problems, which will also bring trouble to post-press processing.
VI. Printing Surface Processing
Surface treatment, color box packaging boxes are often over-gloss glue, over-dumb glue, uv, over-gloss oil, over-dumb oil and gilding.
VII. Die-cutting Molding
Die-cutting process is an important part of post-press processing technology, but also the last link, do not do well, the front effort will be wasted, die-cutting process pay attention to indentation on the line do not explode, do not die-cutting inaccurate.
Many color box boxes need to be glued, glued together, and some special structure boxes need not be glued, such as airplane boxes and sky and earth covers. After bonding, it can be packed and shipped through quality inspection.
