Common printing methods of paper straw manufacturers:
1. Pre-print
The overprinting accuracy of this paper straw printing method is very high, which is very suitable for paper straw manufacturers with large consumption, because of its high efficiency, this printing method is used. High overprinting accuracy, does not affect the strength of the paper straw. However, it only applies to the long version, which requires high quantification.
2, flat/offset/offset
Print a piece of paper first. It's not the same as preprinting. Preprint is web printing, but it is sheet printing. After printing is completed, do not go to the paper straw production line, go directly to the veneer and single or double sided paper straw mounting, and then post-processing. This kind of paper straw is very common in sales packaging.
3, post printing
This printing method is very common in the paper straw factory, that is, the paper straw that has been mounted and pressed over the height is printed directly on the machine, which is low cost, flexible, and has no requirement for quantity. However, because flexographic printing is a direct printing, the roller will directly contact the paper straw, and the ink will be transferred to the paper straw under the pressure of the press roller.
