Jean-Claude,
I attended a printmaking demo by Elizabeth Dove a
month or so ago and her photographic prints from Imagon are pretty amazing, as
is Keith Howard's who has written the book on the stuff. I've seen his
huge portrait Imagon-made prints at CAA conventions, too, and felt they were
equal to any other photopolymer.
Dove made Imagon look SO easy, too. When I
did a lot of Solarplate while in grad school there was a student working with
Imagon at the same time. It looked like too much fuss to me compared to
Solarplate because of a couple extra steps--application of the film to a plate,
and developing it out in the sodium carbonate. But when seeing Dove do it,
I don't know why I thought it was so difficult. However, she did work with
Howard for a couple years! So it made me want to revisit this product, due
to its incredible cheapness compared to Solarplate or KM73. Maybe this
summer when I start calibrating my Amergraph!

Subject: Re: curve for polymer film
Many thanks Jon for all.
I agree with you, ImagOn is too thin then difficult to get range of tone
within so small deep etch (non copper etch but polymer, they call it non etch
anyway). I made some try, using KM73 but very more expensive, for this reason
I bought what they call ImagOn Pro, sold as thicker than normal ImagOn film,
(lamination not so easy than normal), I have to work on.
May be at the end I'l follow your suggestion to concentrate on
Km73
Cheers

Salut Jean-Claude,
My experience working with
ImagOn is that it is much more fragile (but cheaper) to work with than photo
polymer plates. There are also many more steps involved and it's
generally coarse looking stuff overall. If photographic tone is what
you're after, I'd recommend you look at polymer plates and skip
ImagOn. Leave it for the graphic artists to wrestle with.
There's alot more written on polymer plates besides.
If you decide to
take that route, I recommend Toyobo KM73 plates available from Box Car
Press. The curve I use with them is posted in my Polymer Photogravure
procedure page, which might be a good starting place for you, considering
you've already got some experience with ImagOn. The URL is:
http://intaglioeditions.com/procedures/polymer_photogravure.html
The
curve I'm using is posted there for reference, but I don't go into how I
derived it since it's been a continuing process as my variables change as I
refine my workflow. There's been alot of work done on new methods for
deriving process compensation curves since Dan Burkholder's wonderful
book. Mark Nelson's Precision Digital Negatives process has yielded
great results for some people using polymer. A new book that came out
recently that greatly simplifies the process of deriving curves for Alt
Processes is called "Digital
Negatives: Using Photoshop to Create Digital Negatives for Silver and
Alternative Process Printing". It's available from Amazon and I highly recommend checking
it out.

type="cite">Bonjour Last year I spent much time working with
ImagOn photopolymer. The results where so and so, I finally stopped
working on the process. Difficult to talk densitometer even step
tablet with photopolymer users not very interested in photography but art
etching etching. Polymer film is UV exposed under B&W positive
film and it seems very difficult to obtain shadows, mid tones and lights
with only one plate. Now working on inkjet printed negative for VDB
process, thanks to Dan Burkholder, I think may be inkjet positive printed
on pictorico would work assuming I apply the good curve. Is somebody
working on the same process? jean-claude
