For quality contact printing, how would you evaluate the results of doing lith v Palladium v Lodima?
I can see the advantage of palladium with its surface characteristic. Do lith and Lodima share this feature?
Also, which is least toxic/dangerous?
Which is most expensive?
Which gives the most consistent, predictable results?
I'd suggest viewing some prints (in person) and decide for yourself. This is an area of strong opinion!
One of those is easy enough- for Pt/Pd, Bergger COT320 is what most people use. I also like kozo mulberry paper a lot, but it's too textured and thin for some people's taste.
