Abstract
Improved resolution and quality of ink jet printing is achieved by treating the paper with an overcoat preventing wetting by the liquid ink. The surface tensions of the liquid droplet keeps it spherical and droplet shrinks as the liquid evaporates, leaving a small dot of concentrated pigment or dye. Fusing or overcoating is used to increase durability of the printed sheet.
