Thermal Inkjet (TIJ) is becoming increasing important in the industrial coding market and the question of how to increase the throw distance with this technology is often discussed. Much of the previous work carried out has concentrated on the effects that the waveform used to fire the ink from the cartridge can have with little focus on the inks.In this paper we examine the throw distances achieved with some of the TIJ inks available from Domino Printing Sciences. Using image quality measurements taken from printed 2D datamatrix codes the effect that ink formulations can have on throw distance has been studied, including the drop velocity and physical properties. The effect of using different TIJ cartridge technologies has also been investigated.
