发明名称 High quality halftone process
摘要 The invention provides a printing method of printing on a print medium. This method comprises: performing a halftone process on image data representing a tone value of each of pixels constituting an original image to generate dot data representing a status of dot formation on each of print pixels of a print image to be formed on the print medium; and generating the print image in response to the dot data, by mutually combining dots formed on print pixels belonging to each of a plurality of pixel position groups in a common print area, the plurality of pixel position groups assuming a physical difference each other at the dot formation. A condition for the halftone processing is configured such that at least one dot pattern among dot patterns has a given spatial frequency characteristic in a first predetermined specific direction on the printing medium for at least a part of the input tone values, each of the dot patterns being formed on the plurality of printing pixels belonging to each of the plurality of pixel groups.
