Two things come to mind: 1) to answer your question directly the only
other real "format" would be a Scitex CT. 2) The "variations" within the
various TIF file type would all need to be addressed. Along a similar line,
there is a so-called "5 file DCS Format" which is a split up hirez-type EPS
format. The client page layout application places a small, lorez EPS file
that contains information linking it
to the hirez components. eg.
FILENAME SIZE (K) TYPE
-------- -------- ----
myfile 100 K /* lorez file for placing, &
quick proofing */
myfile.C 4526 K /* cyan hirez data channel */
myfile.M 4526 K /* magenta hirez data channel */
myfile.Y 4526 K /* yellow hirez data channel */
myfile.K 4526 K /* black hirez data channel */
In my opinion the OPI server would recognize a few things: whether you
were printing separations or composite. In the case of separations, the
server would need to discern the separation being printed and to send the
appropriate channel's data. Or if hirez composite data was being required (for
instance when printing to a high end digital color proofer expecting
composite postscript input), the OPI server would need to fold the separations
into a single CMYK postscript file.
