Patent ID: 8678534

Claim:
A method for printing a desired pattern on a substrate, the method comprises: receiving or generating printing instructions for printing multiple patterns during multiple printing iterations, wherein the multiple printing iterations comprise a first and second printing iterations; are, and printing the multiple patterns during multiple printing iterations; wherein the printing comprises: printing, during the first printing iteration, a first pattern of mask ink on an object, by a first group of nozzles; printing, during the second printing iteration, a second pattern of mask ink on the first pattern and by a second group of nozzles, the second group of nozzles differs from the first group of nozzles; wherein the second group of nozzles is offset from the first group of nozzles by an offset that corresponds to the offset between the first and second patterns; wherein a superposition of the multiple patterns differs from a desired pattern a tolerable difference even when a nozzle of the array of nozzles malfunctions.
