Special Colors
TrapWorks can trap special (spot) colors by using their CMYK equivalence values to esti-
mate relative luminance against process colors. It then decides which color to spread at each
boundary. To do this, specify an ink as one of the following types: Normal, Opaque, or
Transparent from the Edit Separation dialog in the Separation Setup dialog. Normal inks
mix the same way as process colors. Opaque ink is absolutely opaque, so any other ink may
spread under it. Transparent ink is effectively an overprint, so it should not be choked or
spread, and it does not obscure objects printed under it.
The category names Opaque and
Transparent are typical. Other overprinting needs may fall into one of these categories.
Troubleshooting
Limitations
TrapWorks can trap most kinds of fonts, including Type 3, Type 4, and Type 0 (composite
fonts, for example: Kanji). TrapWorks cannot handle a small number of items/conditions:
•
Patterns: cannot trap patterns.
•
Image masks: cannot trap objects using PostScript language imagemask
operator.
•
Painting to disk. With trapping on, paint-to-disk becomes a PostScript language vmer-
ror
ror
(warning message gives error instead of a partial paint).
Calibration Manager
Calibration Manager contains all RIP calibration sets and Tone Curves for every MicroPress
device.
Calibration Sets
Highlight Color
Allows you to specify a color for all traps. More useful in proof prints where it
can help identify where traps are generated. In this case, a very visible color
should be used. Default is bright red. You can increase the Trap widths values
to improve trap visibility in proof prints.

Sets a limit on the number of objects RIP will trap. RIP Monitor window reports
the number of objects in a trapped job. This limit prevents the RIP from
spending excessive time trapping complex jobs. Default value is arbitrary and
may not be the best choice for the combination of typical jobs and system
capabilities.

Images are trapped too heavily Try reducing the trap width, or choose Reduce in the Trap Color menu of the Trap
