A method of calculating wet trap. It quantifies how well a printed ink adheres to another ink, compared to how well that ink adheres to paper. This way of expressing apparent wet trap is defined only for the three basic process inks (CMY). The equation is named after Frank Preucil (1905–1996) who pioneered the use of color reflection densitometry to control and evaluate process color printing in lithography.
