How to uncrop pages?

[Thierry Bouche]

I have a counter question:

the PDF files produced from Xpress + distiller with cropmarks
have their cropmarks out of the viewable part of the PDF, but they do
reappear if I print to PS.

On the other hand, if i add cropmarks to my document (using cropmrks
by Phil Taylor--which is rather latex unfriendly wrt hoffset, but the
first casual use of h_origin i see...) i can put them correct on the
dvi page, and on the PDF file. But if they're as they should be (not
visible in the PDF) they simply don't show at all when i get the PS
from the PDF. this prevents using pdftex as a better prepress engine
(resolution independant, better handling of subset type 1 fonts,
revolutionnary justification mechanisms in the future...) that
tex+dvips.

Did i miss something obvious?
