I poked around in various archives and couldn't come up with anything conclusive so....... I have recently been using (read..... twice) the emulsion side of fixed-out PX-3001 because I like the cream base colour and the smooth lustre finish of this paper. I tried various 'home-brew' concoctions from various compounds used in preparing painting surfaces and finally got a combination & process that makes the liquid Platinum solution 'want' to bind to the gelatine substrate of the paper. However it is a fussy sequence and I would certainly abandon it if there is a simple method for attaining a smooth sensitizer coat on the emulsion surface. Also I tried dammar on a so-so print that was on regular paper and got slightly blacker blacks and livelier shadows. I used it more dilute than for regular finishing to avoid glare and I was wondering if anyone else is using straight dammar successfully or if there are other subtle 'finishes' that give good results. Thanks in advance for the benefit of your experience..... Annie.
