Print head types ink drop formation

Print heads both form and deliver the drop and are often described using terms that describe these two actions. Regarding the formation of the drop, there are several methods, with the following two types being the most commonly used for ink jet printing on textile substrates  

One of the prime attractions of this technology is the relatively low cost, as less specialized materials are required, although the Imig term effect of heat can reduce the overall hfe of the print head (Freire, 2006, p. 45). It can also be physically smaller than piezoelectric units, allowing more nozzles to be packed into a smaller area oti the print head. 

The lack of heat in this process can allow for a greater variety of inks to be used, and, although more expensive than thermal print heads, piezoelectric print heads are currently favored for textile printing (Freire, 2006, p. 48).
