I am a student that has been learning about Lith printing this past semester. My school's department is not very encouraging of any aesthetic outside of their narrow focus of the medium, and have been teaching myself alternative processes for the past year. It's time for my Senior Show and I have been Lith printing my infrared negatives on small sized paper from Oriental and Foma. They've been coming out beautifully. For the show I was to go up to size 20x24 and ordered the same exact Oriental VC at that size. I also tried some old Kentmere, Ilford and Kodak Fine-art that was stored in the studio. None of them would Lith at that size. My negs don't work that big for traditionally printing and am being told to resort to digital prints. PLease Help if you know why Lith printing that big won't work or if you know a paper/chemistry combination that does! I'm using Arista Developer now. Thanks!
