Abstract
An apparatus enables the effect of distance changes between ejectors in printheads of a printing system and the surface receiving ejected drops to be evaluated. The apparatus includes a housing with a cavity having a sloping floor to which a substrate is mounted to receive drops ejected by printheads in the printing system. The floor of the cavity can slope in either the process or cross-process direction. The substrate can include fiducial marks and target lines to enhance the analysis of the effect of changing distance on the ejected drops.
