Carton customers often hear such words, "large area printing is not recommended" or "large area printing cannot be done", why?
First, large-area printing will increase production costs. First, the amount of printing plates and ink will increase, which directly increases production costs. Second, scrap rates will increase, indirectly increasing costs.
Second, the requirements for cardboard are relatively high, and the raw material levels of cardboard factories are different, resulting in transparent, hard and soft cardboard, which will affect the printing of cardboard. So why not choose a better cardboard? I understand this, the cardboard is affected by the weather and humidity, and the amount of glue applied will be affected by more or less, and the cardboard will be uneven, and if it is slightly uneven, the cardboard factory will not return it.
Third, the requirements for printing presses are strict. In this way, the printing machinery of a general carton factory is about 200,000. A printing press that can make a large-scale printing with good effect requires about 8 million.
Then if there is a large area of ​​printing, is there no way?
The answer is that there is a way to choose a carton factory with a cardboard line, so that it can directly intervene in the production of cardboard. Of course, such a unit has a minimum order requirement. Like SF Express, this is the way to go.
Then what if the amount is not that large?
Then you can only choose ink printing, because ink printing is to print the pattern on a piece of paper first, and then paste the paper on the corrugated, so as to avoid the influence of the corrugated on the printing. Of course, this will increase the price of the carton.
If the watermark is directly printed on the paper, can it be affixed to corrugated?
Theoretically, this has been said in the past, but it is still a problem of watermarking machinery. General watermarking machinery cannot print on paper because the paper is too thin.
