Viscosity of printing inks

Print head technology determines inkjet inks major characteristics, the latter being covered in the chapter "Inkjet inks Requirements". A major characteristic, substantially differing from standard printing inks, is the viscosity. While the viscosity of printing inks vary from several hundred up to several thousand cPs (centi Poise) — the viscosity of inks used for inkjet applications is in the range of a few cPs for the SOHO (Small Office and Home) printers and up to 20 cPs for commercial printers using industrial print heads. 

Table I shows that the pigment content and viscosity of printing inks vary widely according to the printing process and application.
