Ink jet print head adapted to minimize orientation-induced line-width variation |
摘要 |
Ink jet print head adapted to minimize orientation-induced line-width variation. The print head having n+1 nozzles. The n nozzles are located at vertices of a polygon having an average side length s<SUB>avg </SUB>and one nozzle located at a center of the polygon. Each side length of the polygon is less than 20% deviation from the average side length s<SUB>avg</SUB>. The n+1 nozzles are configured to ink jet a line having a line-width w; and each of the n+1 nozzles is configured to ink jet a spot having an average area-equivalent spot diameter d which satisfies the inequality conditions (I) <?in-line-formulae description="In-line Formulae" end="lead"?>0.7w<=D+(n/pi)s<SUB>avg</SUB><=1.3w. (I)<?in-line-formulae description="In-line Formulae" end="tail"?>
