Abstract

Ink compatibility test is the assessment of the ability of a polymeric material to maintain its

original properties after being exposed to an indicated chemical reagent environment for a

specified period. It is a critical test that will be conducted by all the printer parts that will interact

with inks, be it before the pen firing event in which inks are stored inside the ink tank, ink tube, ink

cartridge or after the pen firing in which waste ink will spit onto spittoon and paper path platen ribs

which act as full bleed printing overspray zone.
