摘要：Spatially dependent colorant interaction effects are identified and isolated fromother aspects of spatially dependent colorant appearance nonuniformities. A
decorrelating function for compensating for the identified spatially dependent colorantinteraction effects is determined. Spatially dependent single colorant compensatingfunctions for compensating for the other aspects of the spatially dependent colorantappearance nonuniformities may also be determined. Image data is processed throughthe decorrelating function, thereby generating colorant values that are compensated forspatially dependent colorant interaction effects. Optionally, image data is also processedthrough the spatially dependent single colorant compensating functions, therebygenerating colorant values that are compensated for both aspects of colorantappearance nonuniformities. The two kinds of compensating functions may bedetermined, calibrated and/or stored at different spatial and temporal frequencies orresolutions. One or both of the compensating functions may be employed to maintainconsistency across a plurality of rendering devices (e.g., marking engines).
