Re: Deep blacks in Pd, Pt/Pd

[Sandy King <sanking@clemson.edu>]

In looking at some of the curves in Dick Arentz' book, Platinum and 
Palladium Printing, the IdMax is around 1.35. I suspect from these 
curves that in practice a maximum density of 1.45 - 1.50 would be 
about the most one could expect to get  from any combination of 
platinum or palladium.

According to the book the curves referenced above were on Cranes 
Parchement and complete working procedures are described. Other 
papers would probably give higher or lower values.

I have read the densities of quite a number of Pt/Pd prints and have 
not seen any maximum density higher than 1.45.
