Another take I
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 a 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.
