I've been doing some lith printing over the past few weeks, and am enjoying the heck out of it. Only one thing is giving me grief: properly fixing the prints. I've been checking for residual silver with the Kodak ST-1 test, and invariably I am getting slight staining. For the record, with my normal silver prints, I get absolutely no stain. I'm pretty fussy about process. If anything, I feel I am probably over-fixing at this stage. I'm using two bath Kodak Rapid Fix (no hardener added), diluted 'film strength', for 4 min in each bath. Seems like heaps, but any less and the staining was even more prominent. The prints looks brilliant, but I'm sure they're bleaching a bit in the fix. Is this somehow related to the relatively long time a print is sitting in the lith developer for? I'm using Kodalith Super RT (from powder) and my development times are between 10-20min. I stop in Kodak stop bath for 30s. I've got the Rudman books, and I don't believe they touch on this subject. Does the lith process take significantly longer to fix than a 'regular' silver print? There's mention that lith prints 'work the fixer harder', which I definitely agree with - I burned through a jug of Clearfix in no time. Any thoughts on the matter would be appreciated. Thanks!
