Printing Ink

  • Printing inks, unlike paints and varnish coatings, are applied to the surface in the form of a very thin layer, which, depending on the printing process, may have a thickness of 2 to 30 μm.
  • The visual characteristics of the ink depend on three main factors, namely: its colour, transparency and gloss. In addition, several features that are interrelated with each other, influence the colour of the ink. The colour depends also on the intensity and saturation, and its purity informs us how dark or light the ink will be.
  • Petroleum-based solvents help both in the dispersal of chemicals in colored inks, and help the inks dry faster.
  • Petro-based resins are also said to enhance gloss.
