I ran an Iris sold by Imation and they called it an Imation 4700. This
came with a proprietary profiling software called Spectral Profiler and it
used a Spectroscan to read the charts. It is pretty closed loop. You made
1 chart from films either a matchprint or press run and another chart ran on
the 4700 with the type of paper you proofed on. Read these charts in on the
spectroscan and you got a profile, but one that couldn't be used outside the
rip/controler software. About the only advantage to this was (with tweaking
of course) was that you didn't have to convert your file to another proofing
simulation. You sent over a quark page with cmyk files and waht you got out
of the 4700 was a good match to film and a matchprint proof. This worked
good for transfering a print to any stock and making a profile for it. I
had several proof setups for running slightly off color bases with non swop
cromalin toners.
