Abstract:
1. A printer, comprising: a substrate transport device for continuously transporting a supply of substrate in a transport direction; a print carriage comprising at least one print head module for depositing a substance onto a substrate, the print head module having a transport axis and a traverse axis and comprising first and second print heads having nozzles for depositing the substance, the first and second print heads being staggered with respect to one another along the transport axis and offset from one another along the traverse axis to form an elongate compound head having a length greater than a length of either the first or the second print head, whereby the first and second print heads overlap one another along the transport axis by at least 45 nozzles, providing nozzle redundancy of more than 2.5% but less than 50% and allowing deposition onto the substrate at different swathe angles with respect to the traverse axis, of contiguous first and second swathes of the substance, from the nozzles of the respective first and second print heads, the print carriage having a transport axis generally aligned with the transport direction and arranged to traverse across the substrate for deposition of the substance in opposite diagonal swathes; and a controller arranged to deactivate a first group of nozzles during a first traverse and deactivate a second group of nozzles on a second traverse during deposition of the substance in opposite diagonal swaths.
