Spatially dependent colorant interaction effects are identified and
isolated from other aspects of spatially dependent colorant appearance
nonuniformities. A decorrelating function for compensating for the
identified spatially dependent colorant interaction effects is
determined. Spatially dependent single colorant compensating functions
for compensating for the other aspects of the spatially dependent
colorant appearance nonuniformities may also be determined. Image data is
processed through the decorrelating function, thereby generating colorant
values that are compensated for spatially dependent colorant interaction
effects. Optionally, image data is also processed through the spatially
dependent single colorant compensating functions, thereby generating
colorant values that are compensated for both aspects of colorant
appearance nonuniformities. The two kinds of compensating functions may
be determined, calibrated and/or stored at different spatial and temporal
frequencies or resolutions. One or both of the compensating functions may
be employed to maintain consistency across a plurality of rendering
devices (e.g., marking engines).
