Tom,

I tried Soemarko with no success, together with some other formulae from the
"Darkroom Cookbook". What I found works well - and everyone who has worked
with lith film tells me this is all wrong - is the following.
1. Pre-flash the lith film 1 sec at f32.5: I needed this to get the low
tones
2. Expose through the inter-positive at f22 for 30 sec
3. Develop in D163 diluted 1:10 with rapid agitation for 1m. Stop, fix and
wash as normal.
That gives me a density range of about 1.5 which is fine for multiple layer
gum printing, and keeps the mid tones quite well. The density curve isn't a
straight line but, hey, its character I'm seeking.

The dilute D163 goes off quickly so you need to keep making new batches for
every half dozen or so sheets.

The alternative - I think Terry's favourite (no doubt he'll correct me if
I'm wrong) - is simply to contact print back onto more RC paper. That works
fine at the expense of longer printing times.

Hi Geoff,

I should  say that the development is tricky! Do you use some formula (like
the one by Dave Soemarko) to keep the lith contrast manageable?
