I hope that's not true. We have a major investment in time and equipment.

It's a great solution, and cheaper too, but after seeing the two, I can't
work without it (most of the time).

We are experimenting now with UCR (actually on the Crosfield it's GCR). It
can be useful, especially when we work from a supplied RGB file and have no
control over the original gray balance settings. It does reduce the
relief, however. It's strange, some people don't like the relief. It may
also prove helpful in my repellance problem, who knows?

Interesting, Luis (if it's ok to call you that?) I just found an old
correspondence between us (Dec. '89 - Jan. '90) where I asked permission to
quote your book "Modern Carbon" about the beauty of the process.
