Method of correcting halftone dot image data and image processing apparatus with halftone dot image data correction

摘要

The invention refers to a method of converting continuous tone image data into halftone dot image data and generating a halftone dot image from the halftone dot image data under given output conditions, comprising the steps of converting continuous tone image data into halftone dot image data based on threshold data produced for generating a halftone dot image having a given halftone dot area percentage under given output conditions; and generating a halftone dot image based on the halftone dot image data. <IMAGE>
