|| A COMPLETE PRINTER MODEL IN ERROR-DIFFUSED HALFTONE IMAGES|
||Jing-Ming Guo; Jin Wen Institute of Technology|| |
|| Generally speaking, the researches in model-based halftoning can be divided into error-diffusion based and iteration based methods. In this study, we propose a modified printer model to eliminate the damage from dot gain effect in printed halftone images. The proposed printer model cooperates with error diffusion and totally solves the dot gain problem in just one processing pass for all kinds of printed dot radii. Moreover, the modified printed image inherently needs fewer printed dots than the image obtained by traditional halftone method. With this modified printer model, it also offers an additional benefit of saving the cartridge expenditure. As documented in the experimental results, the average cartridge saving is around 38.58% with nature images.|
