Problem with Slavich Unibrom & Arista Lith Developer
I have a customer who is getting white patches on his prints when using Slavich Unibrom grade 3 and Arista lith developer. He has informed me that the developer was new and fresh and I know the paper was also fresh.
I have used this paper many times for lith and not had this problem but I usually use Moersch Easylith or Rollei Creative Vintage developers. So I am unsure if the patches are due to a paper defect or a problem with the Arista developer.
Has anyone experienced this?
