The problems were poor dmax, also it had a kind of white speckling as if the sensitiser was not being absorbed properly, this was with and without the use of tween.

1) prebrush the paper with distilled water
2) brush coat (I was using a rod)
3) use PO developer at 150º F.
4) let the paper develop for at least 5 minutes (during that time I saw a few white spots and they disappeared)
Maybe just one of those steps did the trick, but I was getting frustrated and wanted to see a good print on Platine. At that time I was a Crane's user. I'm hoping it will come back. The prints i made were quite good.
Do you do anything special when using that paper as a rule?
I print Pt/Pt on Arches Platine for more than 15 years now and it's a very good paper BUT it needs:
- some warmth (at least and if possible over 20°C)
- a very good humidity level (over 50%)
if you can't have both print on a different paper.
Sounds like summer would be ideal. When it returns, I'll give it a try. It certainly is a beautiful paper and I've seen excellent prints on it.
