I have no idea what this is about so I looked it up and read "Colour
separation. The printing process requires that the publication be separated
into the basic printing colours, i.e., cyan, magenta, yellow and black.
Normally this would be done by image setters. However, many users prepare
the separations themselves. A reason for this could be the desire to judge
the effects before the .nal image setting without incurring the cost. One
could also produce uncomplicated separations using a laser printer and
transparencies. As has been said before, colour separations may be obtained
with the proven macro package cmyk-hax.tex with its excellent choice of
options. The package can be used not only for colour separation but also for
manipulating the colours of individual objects. Colour separations are
achievable with the use of the following commands: [...]
\NoOverPrintBlack-the standard behaviour of Poligraf is to overprint black
paint on previously printed colours-this suppresses such behaviour. The use
of the \Separate command instructs TEX to input the cmyk-hax.tex package."

Is that "trapping"?
