Over the last few days have done a series of test strips to find maximum black on the Hahnemuhle Platinum Paper combined to my metal box UV unit. Coated 3 sheets of 5x8 paper using a brush and the Bostick & Sullivan Palladium chemistry.
I played around with the drop count of the 4 chemicals involved and used the UV exposure unit I bought a few years back for the first time. A few hiccups but I got an exposure of 9-10 minutes as expected to give me a max black for my chemical/paper/exposure unit combo.
Am happy with first results.
