Abstract:

Y_N model-based printer forward characterization, considering the influence of the physical dot gain and optical dot gain, it needs to determine the effective ink dot percentages and the factor n of Yule-Nielson model through single-channel ink limit and nonlinear optimal method. Based on the foregoing, we can determinate the dot transfer function of multicolor printer. Before Y_N model formula factor n and effective dot percentage being determined, it needs to get the sample by printing each primary color inks foot ladder. However, transferring ink to the substrate occurs obvious physical dot gain issues, while the paper absorbing ink ability is limited, so firstly implementing single channel ink quantity control for printer becomes particularly important. Considering the problem of the optical dot gain resulting model accuracy misfit, Y_N model introduces a parameter factor n to correction.
