There is disclosed in embodiments methods relating to the compression of
printing hints. The method in embodiments generates a first set of image
pixels having corresponding printing hints. The printing hints are then
adjusted to produce a second set of image pixels processed in such a way
that an end printed result is visually equivalent to a printed result
using the first set of image pixels thereby reducing the entropy in the
printing hints. The method improves the compression ratio of an image
using printing hints by adjusting the printing hints of pixels that are
zero or fully saturated. The printing hints are adjusted in such a way to
reduce the complexity of the printing hints.
