A method for smooth trapping of thin graphical objects, wherein a thin
graphical object has a width dimension which is substantially less than
the object's length dimension, includes receiving from a trap generator
the location of a trap pixel that should be changed in color; determining
the width of the object containing the trap pixel; comparing the width of
the object with a trap threshold width; if the size of the object is less
than the trap threshold width, reducing the width of the trap region
according to a predetermined relationship; and applying a trap correction
to the trap pixel according to the reduced trap width. The predetermined
relationship may be a linear relationship which reduces the trap width
monotonically for object widths less than the trap threshold width. The
method may be applied to small objects and small font text objects.
