Abstract
A direct-reading densitometric method is described for the determination of the approximate cross-modulation cancellation of bilateral variable-area prints. This method makes use of the relationship between film rectification and the accompanying change in the mean transmission of a modulated print. The static measurement tells the direction as well as the approximate amount of the print density deviation from optimum. Complete measurements can be obtained with only a few inches of film, compared with several feet required by the routine dynamic measurement of cancellation. The method may simplify the checking of release prints.
