Abstract
A method and system for adaptively compensating for the printer MTF. The MTF compensation applied locally depends on the local mean: Several compensated High-pass images are computed for different mean values. Then locally, depending on the value of the low-pass band, one compensation high-pass value is selected for the final result.
