Paper surface efficiency (PSE), a paper property integrating gloss and absorbency, can be used to evaluate color reproduction after the interaction of paper and ink. But it was shown that the color reproduction was still related to paper whiteness in practice. So it is important to amend the PSE formula. In this paper, an assumed PSE formula which integrates gloss, whiteness and ink absorbency is firstly presented, and according to experimental data, it can be well forecasted that the change of these principal paper properties would affect color reproduction result via the new PSE formula. The data connection between the assumed and new PSE formula and ink color reproduction based the description of photo-density measurement and chromatic one was studied subsequently. The results showed that photo-density measurement was simpler and more practical than chromatic measurement.
