Gilsonite in printing inks

 Gilsonite in printing inks

Gilsonite has been used as the first wet black carbon agent for the dark colors of newspaper and magazine inks. High concentrations of Gilsonite have been used in the composition of newspaper printing inks. The main use of gilsonite is as an additive for the dispersion of black carbon particles, which is the dark color of printing inks. Gilsonite is normally used in doses of 2 to 5 percent in different formulations and color combinations, but sometimes 10 to 20 percent gilsonite is used as a low-cost alternative to other resins in black ink compounds.
