Abstract
This invention relates to a method and apparatus for implementing a trapping operation on a digital image during image processing. Some embodiments of the present invention provide an intelligent trapping process to compensate for registration errors or halo effect errors by an imaging device. At various times, a set of customized trapping parameters may be determined for the device based on its actual or estimated performance. The imaging device may be checked automatically on a periodic basis, in response to an event, or upon request. The trapping parameters may be unidirectional and may vary temporally or spatially. The imaging device can then print images based on its customized set of trapping parameters.
