New methods are proposed for printing a full resolution image on a limited output device. These methods include expanded nonlinear ordered dithering (ENOD) and modified error diffusion (MED). ENOD benefits from simple processing that reduces the computational time of the ordered dither, and an aperiodic and uncorrelated structure that avoids the low-frequency graininess of blue noise masking. The proposed ENOD also uses a nonlinear function that can accommodate the overlapping phenomena of neighborhood dots. The MEd adjusts the diffusion of a quantization error according to the characteristics of the input image. Consequently, the proposed algorithm can produce high quality images while using low-cost color devices.
