Study on the Relationships between New Paper Surface Efficiency and Printing Quality Parameters

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. 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 linear relationships between new PSE formula and ink color reproduction based the description of photo-density measurement were studied subsequently. The results showed that new PSE formula can be used to predict effectively ink color effect.
