Abstract
Multiple-resolution, interlace, ink-jet printing is accomplished pseudo a single array with multiple nozzles by assuming a psuedo pel (picture element) spacing k' between the nozzles. The ratio between the old resolution and the new resolution is k'/k where k is the actual pel spacing between the nozzles. The print-data must be processed and the print head moved based on the pseudo pel spacing k'. The array of nozzles will still print in an interlace manner so long as k' and Nt (the total number of ink jet nozzles used) have no common factor.
