The process by which paper absorbs ink
- 2024-05-23 17:47:41
- admin
Paper ink absorption is not only related to the degree of porosity and capillary state of the paper, but also related to the surface properties of the paper fiber, the content of fillers, pigments, adhesives, ink composition and characteristics, printing methods, printing pressure and other factors. In actual printing, the absorption of ink by paper can be divided into two stages. The first stage ...
