Abstract

A study examined the causes of mottle and strike-through on ink-jet printed uncoated copy paper. Mottle results from the free movement of ink on the paper surface leading to uneven ink distribution. Strike-through occurs when free ink on the surface of paper finds a defect on the surface and then funnels into and through the defect to the back side of the paper. Mottle and strike-through were quantified with a stochastic analysis method using Verity IA software. Based on the mechanism of mottle and strike-through a study was made of paper additives that would either reduce free ink or overcome surface defects. Absorbents, adsorbents, and mordents reduce mottle and strike-through. In addition, the study identified several additives that changed how paper absorbed ink-jet ink. The additives very effectively reduced the print problems. The methods of reducing mottle and strike-through can be additive as seen in recently developed surface sizing agents.
