    Drop count for 20 x 24 Palladium

    Would be interested in hearing the ULF masters input on what drop count they felt appropriate for a 20 x 24 palladium print.

    I am using palladium only with FO # 1 and the Na2 method of contrast control. I am using a Richeson brush for the coating. On a related note is the NuArc 40 1Ks (not sure if I have the model number correct) my best option for even illumination or will the new unit Sandy has been testing be a viable option for prints this size. I currently use a 26 1Ks unit from NuArc, and there seems to be some light fall off on some of the negatives I am printing but oddly enough not all of the negatives. Just as likely could be operator error!

    Thanks in advance,

    Monty

    From what I've heard, there is or can be light fall off with the 26 1K units. AS for the drop count you should be able to use a multiple of what you are using to make smaller prints like an 8x10. Of course a lot depends on the paper too.

    I would get some inexpensive pipettes and pumps. You'll go nuts trying to count that many drops. My rule of thumb is .1ml of each solution per 10 square inches. So that would be 4.8ml of each solution for your print.
    I just want to feel nostalgic like I used to.

    As Clay said, at least 5ml of solution. I run a little dry on prints that large. I tend to use 6ml and a push rod.

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    Monty,

    See my message in the Contact printing forum about the Amergraph ULF-28. I finished my review of this unit and it will be up at www.unblinkingeye.com very soon, perhaps as early as tomorrow.

    Thanks men. Excellent suggestion on the pipette as counting has been a bit laborious. Sandy I'll look for the review this week.

    Thanks again,

    B&S sell pipettes and little pipette pumps... a must have for larger prints and really not very expensive in the big picture.

    Gather up your all your droppers and walk to the back door. Open it and throw them as far as you can.Drop size can vary from dropper to dropper. Pipettes are the only way to go. Get two 2ml for the FO and Pd and a 1ml for the na2 along with 3 pipette pumps. Also if you are using the na2 method then it is a pt/pd print not a palladium print. You can dial in the na2 real well with a 1 ml pipette. Solution amounts can vary from paper to paper also. Refer to Arentz's book, he gives a great chart for na2 on page 59 of the second edition.

    As others have already said, pipettes are the only way to go for prints larger than 8x10. As far as volume is concerned, Clay, I don't know how you get a complete and even coating with .1ml/10 sq in. unless you are coating on a very non-absorbent paper. I only coat with a brush (2" Windsor-Newton #606 Sceptre Gold) and use 3.5ml of both FeOx and Pt/Pd for a 12x20 print on Cranes Platinotype. It should be noted here that the paper you are using has a major impact on the amount of solution needed for an even coating. Fabriano Artistico and Opaline require significantly less volume of solution for coating due to more sizing in the paper than platinotype. Coating volume is paper dependent.

    My numbers are more in line with Clay's. I use 2.6 ml of ferric and pd for a 14x17 print (240 sq. in.) with a 4" Magic brush on Fabriano AEW, COT 320 and Rives BFK. I don't use p-type.
