    Definitley a no on the stonehenge in my opinion. Dipping it gave me muddled midtones and a grainy texture. Double coating gives more than enough DMax. Mike, PM me your address and I'll send you a palladium on Stonehenge--or I can meet up with you in Dallas this Saturday if you're free as I haven't seen the latest exhibits at Photographs: Do Not Bend or at the Afterimage Gallery.

    I would recommend against the oxalic acid bath for both Lenox and Stonhenge. The bath will increase sensitivity and Dmax, but it causes a grainy look.

    Arches Platine and Platinotype are *not* the same papers. Platine is made in France by Arches, Platinotype in the US by Crane.

    Bear in mind that papers such as Platine and Platinotype are made especially for Pt./Pd. printing and you can generally expect some consistency from batch to batch. Other papers, including Lenox, Stonhenge, Twinrocker, Rising Drawing Bristol, etc. are made for a wider market and are subject to variation in manufacturer that may alter significantly the way they respond to Pt./Pd. printing. For example, I recently purchased a 100 sheets each of Rising Stonhenge and Lenox. The new Stonhenge has performed very much like other batches I have used in the past, but the Lenox is quite different and in order to use if for Pt./Pd.printing some considerable modification in my working procedures will be necessary.

    In any event my advice during the learning phase of Pt./Pd. printing would be to stick with one paper until you have really good control of the process. Working with several at the same time could well drive you mad. And because you can expect some consistency with papers such as Platine and Platinotype it would probably be a good idea to just bite the bullet on price and learn with one of these papers. On the other hand, I really like the surface qualities of Rising Stonhenge, which costs a lot less than Platine and Platinotype, and have found its working qualities with kallitype and pt./pd. printing to be very consistent.

    In any event I have learned about all I want to know about kallitype and Pt./Pd. priting and am about to return to carbon printing where I don't have to worry so much about how the paper will work with the process and I don't get all these unpleasant surprises with new batches.

    Update - well ran out of the Cranes and ordered some COT320 and Plantinotype and well...let's just say I understand why Jorge gave me such a hard time about the Cranes KF. This is some very nice paper and the COT320 is WHITE!! Now to see if I can get a good coating with the new brush and paper.

    Off topic - Has anyone made any notes on temp. during exposure? Because of space, I am doing the exposure outside - yeah the bugs love the exposure unit at night until now. And since it is in the 35-45 F range was wondering if that would have any affect. One thing with the Ziatypes have already noticed is that the cold - DRYER - air does have some impact on the process, harder to keep the humidity constant on the paper.

    We're in the middle of a little cold spell in Ca and I won't print until it rains this weekend. Even DOP is effected by humidity quite a bit in my experience. Enough so that it's not worth it for me to bother printing when the humidity goes below 60%, which is almost always the case when it gets cold here. When I lived in Texas and the Northerns came down, the Rh went through the floor so I can't imagine trying to print.

    I coat in my bathroom so I just take a shower before coating

    Mateo, that really helps to know..had NO idea that RH played such a major part in all of this. Makes one wonder how much impact it has on traditional process. Thanks..you guys were right about the paper..WOW!

    I haven't done any printing because of lack of proper amounts of sun while I'm at home.

    Diane,
    Printing with the sun here in MO will drive you crazy. That's why I'm the way I am!
    Good luck

    That is what I love about living in Northern AZ at 6500 feet. Lots of sun. This has been a great thread. My exposure unit is really big and yellow so when I try this it is good to know that it is consistent. My POP times have not changed since October.

    I hope this is not a hijack but in the desert SW there is so little humidity that you folks' comments about humidity have me worried. How big a deal is RH in palladium.
