Abstract:
A method of preparing source print data corresponding to a pattern to be imaged on a print medium, the source data having a source data resolution of data points in a horizontal direction and a vertical direction, comprising:setting a final print resolution in the horizontal direction and the vertical direction; setting an actual nozzle firing resolution for each sweep of an inkjet printhead in the horizontal direction and the vertical direction, the actual firing resolution being lower than the final print resolution in the horizontal direction and the vertical direction than; expanding each source data point into one or more pixels of firing data to produce a firing data set having a firing data resolution the same as the final print resolution; and successively masking the firing data set at the actual firing resolution to generate a series of sweep data sets, each sweep data set containing firing data for an individual sweep of the inkjet printhead.
