Help for D-85 LITH Developer and FX-37 developer.

I've formulated 2.5 liters of two solutions D-85 (kodak lith developer). I
don't find Paraformaldehyde and i've replaced it with around 200ml of
acetone (82.5 mm x 2.5) but the solution DON'T WORK!

For a test, i've mixed 4 parts of solution A with 1 part of solution B (no
water) and i've make a strip test with 2 min, 4 min, 6 min, 8 min and 10
min. exposure time. I've immersed the strip into solution and after *10*
minutes the strip test was always white (no halo, no shadows)

How can be happened?

Sorry, have patience, a second question:

What is life time of FX-37? My formulation have now 4 mounths.

thanks to all and sorry for my english!

Hard to say. You must remember that few brands of paper really "liths".
Try with following: Fortezo, Maco Expo, Kentmere Art Classic. Another
way: switch on Kodalith developer or Maco Lith dev. For example, Agfa
MCC liths well in Maco Lith and it is always in stock from common
dealers and cheaper than others. But if you are on the path: "wanna-brew
myself-MY-OWN-stuff", I think that P. Gainer Vit C + Hydroquinone +
Sodium Carbonate works fairly well as a lith developer without typical
drawbacks of D85 and without poisonous matters like paraform. However
take care about streakings and heavy and large spots with this formula,
that is unstable. You can read more here:

with acetone don't work.

thanks

yep ! now... pyroWoman ))

 

hum, never lith printed with, sorry.

Dunno about ornanno S3 lith, but surely will work if they label it
that-a-way. Sorry, can't help ya with D85, I'm not a chemiman.

see you.

 

Why would you think acetone would substitute for paraformaldehyde?
Why not just buy Kodak Litho Developer?

because i needed use it immediately and it's too difficult to find in
italy. :-(

 

Why not just buy Kodak Litho Developer?

Try stores/companies that sell to printers, as in printing newspapers,
printing menus, printing business forms .... these stores will all carry
lith developer - many photo stores don't (heck, many photo stores
around here don't even carry Dektol).

When i can do it, i prefer to mix my chem manually. With this procedure i
can have mach more control to process, and i can modify it ever needs.
i have buyed too chemicals by now that i use when possible. ;-)

thanks

If the original formula is with parafolmadehyde, then of course it doesn't
work without it.

NO! the original formula is with parafolmadehyde, but is specified that it
can be replaced with ACETONE.

"You may substitute 82.5 millilitres of acetone for the paraformaldehyde"
