A method for correcting for edge defects caused by print characteristics
of a print engine includes printing a set of actual color patches
corresponding to a desired set of colors; defining an edge region and a
uniform area region in each of the patches; for each color patch in the
set of actual color patches: determining a difference between color in
the edge region of the patch and color in the uniform area region of the
patch; and generating an edge response to adjust color output of the
print engine in the edge region to substantially match color output in
the uniform area region. The method can perform edge correction for any
edge region of an image. In one embodiment of the invention, the edge
region may be determined by a trap engine associated with the print
engine and the method can provide correction for trap pixels.
