Matters needing attention when printing:
As far as corrugated paper printing is concerned, there is no special printing method. Gravure printing, gravure printing and offset printing are the main printing methods.
In the embossing process of beer box, before the corrugated shape is processed, the liner paper is sent to the flexographic rotary printing machine for printing, and then bonded with corrugated core paper and another liner paper to become corrugated packaging material.
Whether rotary printing or sheet-fed printing, corrugated paper uses relief made of resin material. Flexographic printing using water-based ink can be printed accurately and at high speed, regardless of the smoothness of the backing paper used in corrugated paper production, and it is a very effective printing method. In addition, flexo printing ink has good opacity, and bright colors can be printed on the cowhide base paper used to produce mutually dull paper.
In the plate-making process of resin relief used in the past, the cleaning process using organic solvent is essential. Later, from the plate-making process, some plates that take into account environmental harmony were adopted, such as plates that can only be used by washing with water. A printing plate that can be used for thermal development; Using liquid photosensitive materials for UV curing (non-photosensitive liquid recycling) is an environmentally coordinated printing method.
In Japan, however, the high screen count process of flexo printing has not made much progress, and most of the flexo printing products seen in shops are 80-screen products. In Europe and America, especially in Europe, flexographic printing is the mainstream of corrugated materials, and you can see flexographic products with 100 ~ 140 mesh line.
