A method and system updates individualized calibrated tone-reproduction curves.
A plurality of predetermined stored calibrated tone-reproduction curves are used,
each predetermined stored calibrated tone-reproduction curve corresponding to a
distinct media type and halftone type combination along with a plurality of predetermined
relationships between each stored calibrated tone-reproduction curve and a reference
media type and reference halftone type combination. A new tone-reproduction curve
corresponding to a reference media type and reference halftone type combination
calibration operation is generated, and each predetermined stored calibrated tone-reproduction
curves based on the newly generated tone-reproduction curve corresponding to the
reference media type and reference halftone type combination and the plurality
of predetermined relationships between each stored calibrated tone-reproduction
curve and the reference media type and reference halftone type combination is updated.
The TRCs can be applied upon a page basis. Moreover, generated TRCs can be mapped
to existing TRCs to save memory.
