Not only does no rip do this, it's becoming less of an issue.
Dot worship is falling by the wayside for prepress proofing.
Speed and cost is winning out.
I have a Kodak Approval and I can hardly give away the proofs now
becuase of our HP 5000.
The original way of postscript was to rip a bitmap with dots included
and then pipe it to an imaging device.
Modern systems don't screen the ripped file to allow each device to
handle their own screening. By modern systems I mean systems like Scitex
or Rampage. They use a CT+LW method to allow for post rip trapping.
This also allows for outputting the ripped file at different screen
rulings. This allows us to output the ripped file to a plate/filmsetter
or a proofing device.
Given that the ripped file is not screened, it would be very difficult
for both proofer and setter to have dot for dot exactness.
Scitex does offer a platesetter that can have either plate or proof
material in it.
That's probably the only way to do that.
But, your best bet is to get over dot worship. The industry is moving
away from it.
