In recent years, matte coated paper has enjoyed wide spread usage for ink-jet applications. The coating performance is strongly influenced by base sheet properties including fiber coarseness and base sheet absorbency. Base sheet absorbency, which is elevated in terms of internal sizing, is a crucial property of ink-jet paper.

The objective of this research was to evaluate the influence of size level and fiber coarseness on ink-jet print qualities. A secondary objective was to examine the size reversion phenomena and to quantify the effect of size level, pigmented coating, and fiber coarseness on size reversion.

The results showed that the print density was higher for the sheets made from coarser species. It increased with size level, and decreased with coating level. Delta gloss increased with coating level. Sheets made from coarser species had poorer grid roundness values. Size reversion was observed for all the samples with time. Size reversion was not significantly influenced by coarseness, size level, and coating level.
