Abstract
A first series of control patches is printed with a first marking engine. A second series of control patches is printed with a second marking engine. Relative reflectance values of the patches printed with the first and second marking engines are measured with respective first and second engine response sensors. Based at least on a difference in the measured relative reflectance values of the control patches printed with the first and second marking engines, a relative engine to engine error is determined. The engine to engine error is decomposed into components. Based on the decomposition, adjustment of at least binary values of a digital image is determined so that print density of a first marking engine output substantially matches print density of a second marking engine output.
