Print device having a recording matrix switching device |
摘要 |
In a print device using a systematic dither method, a sheet direction is identified by a sheet printing direction identifying unit. If the direction is identified as a lateral direction, threshold values of a recording matrix are rotated by 90 degrees by a threshold value altering unit. A binary image is reproduced from halftone image data on the basis of the recording matrix by the systematic dither method.
