4 Steps of the Thermal Inkjet Principle | InkJet, Inc.
Thermal inkjet or TIJ technology uses a drop ejection process, storing ink in a cartridge that regulates the pressure of the fluid. Inks are then delivered to the firing chamber to be heated at more than 1,800,032° F / 1,000,000° C/second by an electric resister.
TIJ has specialized inks with fast dry time. CIJ has a wide variety of inks for industrial applications with fast dry time. TIJ is the best choice for printing on porous surfaces such as paper, cardboard, wood, and fabric. Dry time is very good even with mild inks.
