Abstract:
1. An image processing method for producing and processing image data based on input data which image data are sent to an image forming apparatus for forming an image on a paper form on which apparatus a recording head for ejecting a liquid drop of recording liquid is mounted and which apparatus is capable of performing double face printing, wherein color space transformation processes that differ between single face printing and double face printing are performed when input data are transformed into color space values for the image forming apparatus, (i) by multiplying an input tone of a color management process by a ratio for double face, such that a ratio of an adhering ink quantity for single face, secondary color and highest tone to an adhesion quantity regulation value for double face is less than a ratio for double face, and the ratio for double face is less than one, and (ii) by outputting a tone immediately below the adhesion quantity regulation value for double face for a tone such that the adhering ink quantity is over the adhesion quantity regulation value for double face.
