<P>PROBLEM TO BE SOLVED: To provide a technology capable of preventing the unevenness of a printed image caused by wavy deformation of a sheet. <P>SOLUTION: When input image data is assumed to express an image with a uniform gradation value and the sheet is carried in a flat posture without deformation during printing, correction by means of the input image data is performed so that spectra of spatial frequency differs between a plurality of first-type printed partial images printed in a plurality of first-type areas on the sheet and a plurality of second-type printed partial images printed in a plurality of second-type areas on the sheet so as to generate corrected image data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
