This paper describes a new model based error diffusion method to compensate dot overlapping. We designed 32 test patterns to measure printer non-linearity. The effects of four neighboring pixels are considered in the standard error diffusion. The effect of dot overlap is exactly measured with the conditions of various distribution of ON/OFF neighboring pixels. A new model based error diffusion based on measured non-linearity shows good reproduction of gray scale. It is worth while to notice that there is little assumption about the radius of dot, homogeneity inside the dot, and overlapped area phenomenon. The proposed method is applicable to real environment with little restrictions of the printer dot modeling.
