ABSTRACT:
A jet drop recorder has a plurality of print heads, which print contiguous bands of graphic matter upon a sheet of printing material mounted on a rotary support. Each print head projects a row of spaced jets toward the printing sheet, and the jets print non-contiguous spiral tracks on the sheet. The individual jets are so spaced relative to the track width that the combination of paper rotation and advancing movement of the print heads causes side-by-side overlapping or interlacing of the spiral tracks. Thus each print head prints a steadily widening solid band. The heads each have the same number of jets and the same jet spacing so as to achieve identical track interlacing patterns. The distance between the print heads is adjusted such that the full width printed bands interlace at their edges. This prevents printing of an unsightly seam along adjoining boundaries of two adjacent bands.
