The aim of this study was to relate the adjustments of the main process parameters of an electrophotographic color printing process to the numerical print quality, measured as variation of the CIELAB color coordinates.Samples printed with different process parameter combinations were measured with a spectrophotometer. The variation of the CIELAB color coordinates was analyzed from the parallel measurements.The effects of the main process parameter adjustments on the amount of variation were in line with the visual print quality optimization and paper testing method. The CIELAB value variation could be used to numerically estimate the effects of process parameter adjustments on print quality. The testing environment built can be utilized to collect data for the analysis of the paper property requirements in electrophotography.
