The time series approach is used to develop quantitative indices for predicting the printability of coated gravure and embossed papers. The cavity width and depth distributions are derived from the models fitted to the paper profile data and the acuteness number and pattern depth are proposed as the printability indices for the gravure and embossed papers. The analysis of 32 sets of gravure and embossed paper samples indicated that the new indices are capable of giving fairly accurate prediction of the printability. The dominant peak in the cavity width distribution curve also identified the pattern size of the embossed paper samples. A close agreement is found between the results of the proposed indices and existing methods such as Fogra-KAM, Parker Print Surf and other standard printers' tests.
