Abstract: A method and apparatus for performing printing on a substrate on the basis of data representing a pattern composed of a plurality of parallel rows of discrete image elements. In a known manner, successive strips of image elements are formed on the substrate, each strip being constituted by a given number of the parallel rows which extend in a first direction on the substrate and the successive strips being spaced apart at intervals in a second direction on the substrate perpendicular to the first direction such that a boundary exists between each two adjacent strips, adjacent rows in each strip being spaced from one another with an inter-row spacing in the second direction and the interval between strips of parallel rows of image elements having a nominal value substantially equal to the product of the inter-row spacing multiplied by an integer which is one greater than the given number of rows in a strip.

Abstract: A method and apparatus for printing an image on a printing medium with phase change ink, the printing medium providing a printing area composed of a plurality of parallel pixel rows extending in a first direction, with a uniform spacing, p, between pixel rows in a second direction perpendicular to the first direction, with each row being made up of a plurality of elemental pixel areas. Printing is effected with a print head having at least one set of N nozzles for projecting drops of phase change ink onto the printing area, N being an integer and the nozzles having a uniform spacing, in a direction corresponding to the second direction when the print head faces a printing area, equal to s.multidot.
