摘要
An apparatus for ink-jet printing on a recording medium is provided which includes the steps of jetting aqueous ink drops on paper in the form of an image. The aqueous ink used is a slow-drying (high-surface tension) ink which does not penetrate the paper/paper fibers for a relatively long time. Prior to penetration of the paper/paper fibers, the water in the droplet is quickly evaporated from the ink while still resident on the paper surface. The evaporation process is substantially completed prior to an additional liquid ink being jetted onto the same or adjoining location of the recording medium. The evaporation is rapid enough to prevent the resident ink from substantially migrating/wicking to any adjacent location or into the recording medium. Further the drying energy is transferred to the resident ink spots from the same direction as the printheads ensuring less energy requirement.
