[alt-photo] Re: OLDER PT/PD COATED PAPER, WARMER TONE?

[EJ Photo]

Well, I can't say that I've seen it in a while. I can say that Pt Pd mixes
have a warmer look than a fresh mix. In other words, if the mix you use is
3:1 and you always use it that way, you can pre mix it; put both in a bottle
and rather than measuring a portion of Pt and of Pd each time you coat you
simply use your 3:1 mixture, Yes that will be warmer. Would I expect to see
it show up in a coated piece? maybe. I also suspect that unless you are
careful about how you humidify, the real humidity in the paper may be
different than that of your measured amount; different amount and you have a
different color print. 

How do you humidify your paper?

DEAR MARK,
	As mentioned, the process is exactly the same as those that are less
warm except that this paper aged 3 days.  And, yes, the paper is cleared
(small unexposed dot on boarder).  Just warmer.
		CHEERS!
