A minimal Munsell value error based laser printer model.

The image printed by laser printer may be nonlinearly distorted by dot gain and dot loss. In this case, printer model is usually built to suppress this nonlinear distortion and to make sure the printout result is the same as input image. The parameters of the printer model which will directly affect the printout result are key. In this paper, the chroma or density values of printout result is changed into Munsell value, and optimal parameters of printer model are calculated via the calculation of minimal error between Munsell value and input gray value. And then the minimal-Munsell-value-error-based laser printer model (MMVEBLPM) is established and applied in the green noise halftone method. Experimental results showed that the optimal parameters can be calculated fast and the nonlinear distortion of laser printer is suppressed significantly with the proposed model.
