Because news paper is different from SBS cardboard and some printing papers, it is not coated, is bulkier than cardboard after bleaching, has a lot of porosity on the surface, and has stronger wettability, etc., which is important in the use of ink. Both the application and coating aspects need to be comprehensively considered. For example, based on the analysis of the characteristics of news paper printing paper, some flexo printing is good, but it is not suitable to use a printing press for full-page on-site news paper printing. Because the surface of news paper is rough, the material is soft, and it has strong ink absorption, the color of the printed matter is dull, and printing will also cause the ink to pull off paper fibers (also called paper lint).

What should you pay attention to when choosing newsprint material?

In terms of the use of ink, due to the characteristics of some news paper printing papers such as rough surface, porous structure, and good ink absorption, news paper printing requires a large amount of ink. In fact, high solidity and oil-based coatings are more effective than real organic solvent-based varnishes, but a layer of cheap varnish can make the ink more delicate, so it is possible to consider using some cheap varnish. Glazing oil is used to improve the adhesion of ink. Generally, high-on-site oil-based coatings have stronger effects than solvent-based glazing oils. Dip-coating a layer of high-viscosity high-solid agent or PE epoxy resin film may also prevent the separation of ink paste and epoxy resin, and prevent the uncross-linked color paste residue of the news paper from dispersing and adhering to the hard surface. Cardboard name. You can use varnish to carry out the inner layer twice, fill up and cover the surface of the printed paper before printing, that is, wet-on-wet printing. In this way, the printed matter will have good gloss and a uniform ink layer thickness. In addition, the surface coating can reduce external friction against the ink, especially for the maintenance of the entire page covered with ink. Therefore, the top coating will improve the wear resistance of the ink, especially in the printing field. In flexographic printing, high-texture anilox rollers have a good effect on ink and coating of news paper printing, which can make the ink transfer and coating of printed matter better. In addition, in order to better develop the surface contact of ink on the news paper, soft flexographic plates and gaskets should be used.
