Abstract:
A printing method comprising the steps of:(a) arranging a column of N dot forming nozzles for projecting ink onto a printing area comprising columns on a recording substrate, wherein N is an integer greater than 2; (b) performing a scanning step, the scanning step comprising moving the column of dot forming nozzles horizontally across the printing area and in each column of the printing area depositing one or more dots from a subgroup comprised of S dot forming nozzles from the column of N dot forming nozzles, wherein S is an integer of from 1 to about Nâˆ’1; wherein during the scanning step: (i) in each column of the printing area not more than every Gth nozzle deposits a dot and a single nozzle deposits a dot not more than every Gth column, wherein G is an integer from 2 to about S; and (ii) the subgroup of S dot forming nozzles is shifted vertically among the N dot forming nozzles in at least two adjacent columns according to a predetermined pattern; (c) advancing the recording substrate vertically in a first direction by a height of about Q nozzles, wherein Q=(S/G); and (d) repeating the scanning step.
