I highly doubt that Lightroom does anything to the file sent to your RIP
than give it a pdf. From my experience Lightroom absolutely puts the
correct color space info in the pdfs it sends to printer drivers. The
postscript driver is doing something weird to it. Could be some weird
communication mishap but hard to trouble shoot from here. What happens if
you set this up using a generic postscript printer driver and just select
the correct ppd for it?
