An analytical computer model of an ink jet printing system was created. Based upon the values of 13 input parameters, the program delivers predictions of the forces acting on individual drops and their resulting dynamic behavior. Predictions of drop displacements and flight times were used to infer drop pattern appearance resulting from a given input signal. The computer model was based upon theoretical work plus extensive empirical measurements. Drop behavior was predicted with modest accuracy. An improved understanding of ink jet printing systems and numerous recommendations for their use were also derived in this study.
