Another take 3
Scanned IR lith print.
Rolleiflex T w/ Tessar 75 mm/f3.5 + Rollei IR filter.
Sept 12, 2024.
Rollei IR 400 in Adonal 1+100, semistand 1 h.
Same neg, different paper:
Lith printed on Fomabrom Variant IV 123 BO and developed in Moersch Easy Lith (25A+25B+40D+100OB+H2Oqs900).
Se 1+9 30 sec.
These are the differences between warmtone and coldtone lithable papers.
The Fomabrom Variant IV 123 BO was a "short living" attempt by Foma to make a paper which could be used for Bromoil (and maybe replace the original cold tone FB Variant IV 123, which was a very good lithable paper).
This one was good for both bromoil and lith printing :-).
When lithing coldtone papers, you want the "pepper" to appear. It's by far not as colourful as warmtone papers. But on the other hand not so "high contrasty", so you can get more b&w nuances from the process. Which, btw, is much slower than the warmtone lith process. Expect exposure times to be around 5 min and developing times up to or above 20 (!) min. That of course depends on your "soup".
This was perhaps too much boring information, but if I can pass the knowledge ahead to coming b&w analog printers, it's worth it :-). And I'm of course not taking credit of any knowledge that Wolfgang Moersch possesses. Almost everything I've learned comes from him. Kudos, Wolfgang.
