You can rasterise and colour manage a PS file in ColorProof and Screen Proof
to a 1bit TIFF , AND use platesetter 1bit TIFF's in ScreenProof. Any
trapping would or should have been done of course to the ripped files
upstream for any dot proofing application. To clear up perhaps some
misinformation about ScreenProof, the files bit mapped raster files, are
sent into ScreenProof and processed without descreening or reassembly before
being processed for output on the inkjet. Questions of how colour
information is derived off dot (so called etching etc) is a complex but
necessary operation to extract and build a colour simulation is unique to
each RIP maker. I can say with certainty that linearisation is the most
important step to ensure optimal results ICC or otherwise. Since the notion
of ICC CM is to bring colour into a operative flexible workflow ,
nonetheless iterative correction can bring you closer tolerances with manual
methods such as profile editing or in GMG's methods of truly manual man hour
intensive closed loop iterative table corrections.
