摘要： Printing with a first print engine on a front side of a substrate, and a second print engine on the rear side of the substrate, wherein a first spectrophotometer sensor and a second spectrophotometer sensor are used for spectrophotometric measurements on the blank front and rear sides of the substrate, and producing correction data which represent a deviation of the spectrum representing output signals from the first and second sensors, and wherein a correction derived from the correction data compensates a deviation in the spectral reflectivity of at least one of the front side and the rear side of the substrate. Cross-calibrating the first and second sensors is by processing the spectrum representing output signals of the sensors from identical spectrophotometric measurements.
