Abstract
An inkjet printer system and method for recording an image in a single pass print mode includes a printhead having a plurality of nozzles that are selectively operable for depositing drops of liquid ink or other liquid used in forming of an image in a single pass print mode upon a surface of a receiver medium with a printing resolution R, a dot size Di of the dots resulting from impact of the drops with the receiver medium being in the range of 0.5/R<Di<1/R and a final dot size D after spreading on the surface being in the range of 2½/R<D<2.0/R. The receiver medium has a surface for receiving the drops and a region of the medium proximate the surface has an influence upon drop spreading and the region has a porosity in the range of 0.2 to 0.8 and sufficient to provide a media drop spread factor Sm wherein Sm=D/Di with 2½<Sm<2×2½.
