摘要 <p><P>PROBLEM TO BE SOLVED: To provide an image processing system which can reduce design man hour of a gradation processing and capacity required for a memory holding dither data and to provide an image forming device. <P>SOLUTION: The image processing system 302 includes a dither processing section for performing a dither processing on input image data with multi-gradation. Dither data includes: four dot-like dither data which are used for the dither processing of the input image data of C, M, Y and K color plates and whose mutual screen angles are set to differ; three dot-like dither data which are used for the dither processing of the input image data of R, G and B color plates and whose screen angles are set to be similar to the screen angle of a color becoming a complementary color among C, M, Y and K; and two dot-like dither data which are used for the dither processing of the input image data of the color plate except for the above and whose screen angles are set to be those between the two screen angles in C, M, Y and K. <P>COPYRIGHT: (C)2012,JPO&INPIT</p>
