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 sand 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. 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)0.7+(/π)≦1.3.  (I)
