I have been making lith prints on silver gelatin paper for clients since the mid 90’s. I was introduced to Star Trax a book by Anton Corjbin. The images in this book were all printed by Mike Spry and were jaw droppingly beautiful to me.
Over the years I have used many papers and as chemicals died off have pretty much stayed with Fotospeed LD20 as the developer. In this process we use the emergence time in the developer to determine pull time, certain papers require different Snatch Points and each paper will exhibit a different tonal effect.
In all cases Lith prints are processed after developer exactly like any silver gelatin print and can be toned as well to create further variations.
These prints are highly desirable as they will outlast modern day prints and thus are coveted by collectors and galleries.
Almost any type of negative, colour or black and white will work with this process and one needs to be careful trying to match prints for editions as it is almost impossible to do so.
Therefore I refer to any Lith Print as a unique print
