The Influences of Printing Conditions and Paper Properties on Wet Picking/Repellence of Offset Paper

The wet picking and wet repellence of offset papers were studied using IGT-gst2 printability tester according to change printing conditions as printing speed and the amount of fountain solutions. It was showed that the phenomena of wet picking and wet repellence occurred in turn on the surface of offset papers with increased printing speed and the amount of fountain solution. In addition, in contrast with fountain solutions, printing speed had greater influence on the phenomena of wet picking and wet repellence of offset papers.
