What kind of printing method is used for general paper packaging boxes?

The following three ways of printing are usually used:

Preprint:?

Including flexo preprint flexo preprint and gravure preprint gravure preprint, that is, with the help of roll paper (roll) web feed printing, this printing registration accuracy registration accuracy is very high, plus the number of lines can reach 150 lines / inch. roll face sheet printing, then After printing, the rolls are rewound, put on the corrugated production line, and formed into the required cardboard by single or double-tile machine, and then die-cut, creased, slotted, perforated, nailed, or glued into shape.

2. Lithography, offset:?

The first printing sheet face paper, and pre-printing is different, pre-printing is web feed printing face sheet, and it is a single sheet of paper sheet feed printing, after printing, do not go on the corrugated production line, directly on the laminating machine and single-sided or double-sided corrugated laminating paper, in the back channel processing can be. This kind of carton for sales packaging is very common. Of course, if the carton is only used as a transportation package, generally use the following one way to print.

3. Post printing (post print):?

This is often seen in the three plants to take the printing method, that is, has been framed, pressed through the height of the strike line of the cardboard directly on the printing machine, low cost, flexible, starting quantity is nothing to ask for, but due to the flexographic printing is a direct printing, rubber cylinder will be directly in contact with the cardboard, by the pressure roller pressure will be transferred to the ink on the cardboard. This will undoubtedly damage the strength of the corrugated box after molding. If the pressure is too small, it will produce rubbing, too large, collapse flute.?

The above three have their own advantages, depending on your needs to develop.
