• Why resins are an important materials on packaging inks? Apr 25 , 2021
    Resins are the carrier of the pigment in the ink, which is the core material of the ink. Along with pigments, resins convey important properties to the printing process as part of the ink vehicle. Resins impart many important characteristics of a finished ink, including gloss and adhesion, runnability on the press, and can also help disperse pigment.   The quality of the ink will directly aff...

  • Difference between solvent based ink and water based ink Jun 22 , 2021
    Solvent based ink and water based ink is a different specification for each one of them. We would like to explain the differenct between solvent-based ink and water-based ink as follows: 1. After checked with this figure, It is easy to know that we can get Water-based ink by replacing most of the organic solvent with water 2. Water based ink on average dry at 1/5 of the organic solvent drying rate...
