I know next to nothing about Ilfochrome printing
I just demo'd and trained a guy on an LVT (digital film burner) so that he and the company he works for can have greater control over their Ilfochrome process.
From what he was telling me it is only as easy as the tran's you start with. So they wanted to tweak their film prior to printing (plus they do a lot of computer generated output).
I hope you do it and have great success!!
