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.

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?
