$
[InkEater_minX_minY_maxX_maxY_minDensity_maxSatur
ation_colors]
The first four arguments are mandatory and are defined in millimeters.
minX
and
minY
together define the lower-left corner, and
maxX
and
maxY
together define the upper-right corner of a rectangular ink eater
mark. These measurements are relative to the lower-left corner of the
plate media as defined in the imposition.
●
minDensity
is the minimum amount of ink that any color may
have per pixel column. The default value is 7%.
●
maxSaturation
is the maximum saturation that the ink eater
mark can have. This is of concern when multiple colors are included
in the same ink eater mark. The default value is 180%.
●

eater mark. The default is
SeparationAll
, which includes all
colors. MK2, for example, would included Magenta, Black, and the

other marks in the gutter. Also, it may be useful to create one ink eater bar per
color.
