Ink printing device for multi-colored printing of a recording medium

摘要

An ink printing device for multi-colored printing of a recording medium utilizes a single ink printing head having a plurality of printing jets arranged in a pattern on the printer head body. Printer jets are divided into groups vertically adjacent to one another having individual ink supplies with colors different from one another. In a line-wise printing operation, recording medium is indexed perpendicularly to the printing direction at the end of a printed line by a vertical distance which corresponds to printing width of each jet group. Operation of the printer head affords superimposed printing to effect secondary, composite colors or half-tone shaded patterns.
