Objective To determine the effective ink dot percentages and the factor n of the Yule-Nielsen model, based on Yule-Nielsen ( Y_N) model-based printer forward characterization, considering the influence of the physical dot gain and optical dot gain, through single-channel ink limit and the nonlinear optimal method. Methods The ONYX ProductionHouse 10. 2 software was used to realize the single channel of ink limit, and the value of n (2. 5) of the Yule-Nielsen model was obtained using nonlinear optimization techniques. Results By taking the value of n into the Y_N reverse transformation form, the corrected effective dot percentage was obtained, as well as one-dimensional lookup table of effective dot percentage adding a correction factor n and theoretical dot percentage. Furthermore, the dot transfer function fitted from the theoretical dot percentage to effective dot percentage was obtained. Conclusion Through the single- channel ink limit and correction factor n of the Y _ N model, the influence of the physical dot gain and the optical dot gain on the Y_N model can be eliminated, and the dot transfer function can be accurately fitted from theoretical dot percentage to effective dot percentage.
