STANDARD INK COLORS VS. HIGH OPAQUE INK COLORS

Home | Printing Tips and News | STANDARD INK COLORS VS. HIGH OPAQUE INK COLORS

Standard colors will have more pigment incorporated into them than color matching ink colors. High opaque colors, sometimes called “high definition colors,” will have even more pigment added to the resin and thinner mixture, thus giving the high opaque inks the most hiding power. Please note that the more pigment added will mean less resin, and depending on the material being printed, this may create adhesion issues. With that being said, it is always important to run tests before putting the ink into production.

Any ink additive will reduce the ink’s hiding power, so it’s important to remember this when incorporating them into the ink. A few additives that may be incorporated are as follows:

  • Thinners
  • Retarders
  • Hardeners
  • Flow agents
  • Anti-floating agents
  • Anti-static paste
  • Abrasion resistant fluids

These additives are normally incorporated into the ink just before printing at varying percentages in order to change the ink’s hiding power. Stay tuned for Part 4 in our next newsletter!
