Evaluation of Wet Pick and Wet Repellance Tendency of Paper with the IGT Printability Tester AIC2-5

A method of dampening paper on the IGT AIC2-5 printability tester is described. Using this method the tendency to wet pick and wet repellance of paper can be evaluated. To increase the amount of dampening fluid transferred during the test a new set of dampening discs for the AIC2-5 printability tester have been developed. With the new discs it is possible to further distinguish between papers of the same kind, but with slightly different tendencies to the influence of dampening. A method of determination of transferred amount of dampening fluid is described. Tests with a number of different papers using the new dampening system are described and the test results discussed.
