Arrangement for a printing head in ink mosaic printing devices |
摘要 |
A printing head for an ink mosaic printing device is provided with a plurality of diagonally extending ink ducts having downstream ends converging at a printing location on the printing head to form a printing grid pattern. The downstream leading ends of the ducts are formed with wedge-shaped tapered portions, each having a leading edge wall carrying a discharge orifice for ink droplets. By virtue of this construction of the ink ducts, more ink ducts may be used to form the grid pattern and the various discharge orifices may be placed closer to one another to provide higher printing resolution.
