There is currently no standard acceptable method used to evaluate gloss ink holdout. Four methods are investigated to evaluate holdout. Heat seat ink is used to reduce absorption effects. The K&N ink smear test and the Vanceometer absorption tester are both discounted as inappropriate tests since they look at absorption alone and have widely varied results. The IGT printability tester is an improvement because it involves another major influence to holdout, printing pressure, but does not hold the ink film thickness constant. The Vandercook Proof Press procedure is judged the most valuable since it takes into account printing pressure and absorption, and holds the ink film thickness constant. It also is the closest approximation to the industrial setting.
