Roger,

Just for the record, I agree with you about HP4+ in non-staining developers. I have not been able to get a CI from it of more than about 1.0 with any of the high energy developers I have tried, including D-11 and D-19.

You can use other staining developers of course. I gave the values for Pyrocat-HD because I have done specific sensitometry tests with it for this very purpose, i.e. getting as much CI as possible from HP5+ for alternative printing with UV sensitive processes.


Best,

Sandy
