In order to control the print-through, the value of print-through resistance (PTR for short) was put forward to predict the print-through of lithograph. For 5 given paper samples, the relationships between their PTR and print-through (expressed with ΔEab*) was explored under three sets of printing condition in this paper. The results showed that lower printing press and higher printing speed were helpful to reduce the print-through. And under the same printing conditions, the print-through value of cyan ink print was slightly larger than that of magenta ink print. In addition, the PTR increase could lead to the decrease of the print-through value. In particular, no matter what kind of conditions, the print-through value was almost smaller than 4 NBS when the PTR of those paper samples was larger than 73%, which could be look on as the absence of print-through phenomenon.
