I don&#39;t know the bloom value.

But what paper are you using? I don&#39;t find any need to do extra sizing for Pt/Pd printing. There are at least half a dozen papers that work reliably with no extra preparation--though that can change at any moment when you get a new batch.---Carl</td></tr></table><span id='postcolor'>
I am using Guarro watercolor paper, looks like an 80#....very thin. Again I am stuck with what I can find here. I tried it without sizing and the print looked horrible. So I am trying with sizing now. If it does not work then I will just have to bite the bullet and get it from B&S when I order more stuff.
Thanks Carl&#33;
