发明名称 Printing apparatus, printing method and data processing method
摘要 In a printing system by using matrix pattern processing, a printing apparatus, a printing method and a data processing method are capable of uniforming the use frequency of each printing element and preventing the printing element from locally deteriorating while preventing noise or texture from occurring. In a system for printing an image on a printing medium in accordance with print data obtained through a development which develops quantized image data by using a pattern corresponding to the quantized level of the image data, more than one type of the pattern for one quantized level of the image data are prepared, and types of the patterns to be used when the image currently printed on the printing medium reaches a discontinuous area of the image are changed.
