So this isn’t exactly a support problem for PiezoDN specifically but I am using PiezoDN and wanted to reach out to the community here to see if anyone has seen this before.
Using the same process, chemistry, coating technique and the same target negative I printed the 129 step chart onto both Hahnemühle Platinum Rag and Ruscombe Paper Herschel Platinotype.
The Hahnemühle chart is looking good but the Ruscombe paper is looking very faded, blotchy and has very little contrast (it also has a nasty crease that my vacuum frame seems to be adding but that’s a separate problem).
Has anyone used this Ruscombe paper with cyanotype? I think it should be fine since it is unbuffered (and designed for platinum printing) so I am very confused. Any ideas are appreciated
