Abstract:
A method of printing from a printhead includes virtually dividing a nozzle array of the printhead into first and second nozzle sections. N print masks associated with the first and second nozzle sections govern the deposition of ink drops on a print medium. The N print masks are associated with one swath and are defined as a mask grid. The mask grid is arranged as a series of vertically extending adjacent mask columns and a series of horizontally extending mask rows. The vertically extending mask columns comprise enabling mask columns comprising first mask elements and disabling mask columns consisting essentially of second mask elements. The N print masks are associated with the first and second nozzle sections for printing an input image. Each print mask is defined as a mask grid arranged in an N series of vertically extending adjacent mask columns and a series of Z horizontally extending mask rows. The series of mask rows are divided in first and second adjacent mask sections corresponding to the first and second nozzle sections, respectively. The mask rows of the second mask section are arranged spaced from one another by N−1 adjacent second mask elements and the mask rows of the first nozzle section are arranged spaced from one another by 2N−1 adjacent second mask elements within the same mask row.
