I'm not sure whether you're asking about uses for compensating for
gain in general or ink traps in particular but the difference in gain
between offset on smooth coated paper and, say, offset on newsprint
is significant; ink trapping makes sense whenever there is gain.
Digital type gets printed on all sorts of surfaces. Gain is also a
factor in printing from inkjet printers.
