This is interesting. What are the advantages of sizing paper for platinum?
What is
the effect? How do your prints on hand sized paper differ from prints on
unsized
paper?

To be absolutely accurate and not wishing to mislead what I really meant
was platinum palladium prints. I use the proportion of platinum to
palladium as a means of contrast control.
Some authorities say that platinum reacts adversely with gelatine and that
one should not use gelatine size with patinum. My practical experience
with light sizes has not been to this effect.
I find that a lightly sized paper gives an improvement in apparent contrast
to the extent that an unsized print looks good but a sized print looks
better. The papers I use most for platinum printing are Saunders Waterford
and Fabriano Artistico Satina.
