Continuous tone relief printed photo ceramics
- Some interesting goings on at the Centre for Fine Print Research
This is amazing.
- Hi Mark
Hey, I'm just the messenger on this one! Did you look at the collotype
section of the site? Quite amazing, and actually the best I've seen yet.
But I've done collotype. I suspect, in some regards, these folks are
knee deep in digital... Still, I'm impressed. Did you look at the staff
The topographical relief of collotype, for instance, is the result of
the photopolymer matrix absorbing water, at least in traditional
practice. I suspect that topographic relief does depend upon some form
Any clear film-backed photopolymer is designed for flexography and
application to cylinder printing rather than flatbase. In the "old days"
of flexographic liquid photopolymer you did need to back-expose. This
would ensure an antihalation floor. All current sheet polymer (whether
film-backed or metal-backed) comes already back-exposed. From the site
specifics I don't exactly know what configuration they are using or
where they are getting it. Some of the printmaking ventures into
photopolymer are a bit confusing in this way.
Ha! I suspect other photopolymer users would have a lot to say about
this. But watch out for the ones who are selling!
