Abstract:
Ink jet print head adapted to minimize orientation-induced line-width variation. The print head having n nozzles located at the vertices of a regular or quasi-regular polygon having an average side length savg, and each side length of the polygon is less than 20% deviation from the average side length savg. The n nozzles are configured to ink jet a line having a line-width w; and each of the n nozzles is configured to ink jet a spot having an average area-equivalent spot diameter d which satisfies the inequality condition (I) 0.7w≦d+(n/π)savg≦1.3w.
