First attempt to print Pt over pigment on Japanese Goyu Kozo paper (Mullberry). the paper is very thin, and the difficulty is getting it thru the printer for the color layer
scan of print:
The paper soaks up the solution like a sponge, so in addition to the platinum/palladium and sensitizer, extra water needs to be added. This attempt was adding as much water as solution (image size of this print is about 8x10). i have some 11x14's to do, but need to get the workflow down on a smaller size first. The paper is fairly translucent after you print on it, so you'd need an additional white backing to provide the 'white' of the image
ok... getting the knack of kozo and platinum over pigment. The paper just drinks the solution, so after some experimenting, the ideal is to add as much extra water as you put in the Ferric Oxalate solution. For an 11x14, it's 36 drops Ferric Ox., 24 drops Palladium, 12 drops Platinum and then an additional 36 drops water.
Here's a scan of the 11x14 print
Ok folks- you that mask your negatives prior to contact printing using construction paper or such - do you have any issues with maintaining contact pressure in your frame? I tried to outsmart myself by using some red film for stage lights, thinking that red would be a sufficient mask (even if transparent) due to UV sensitivity of emulsion (saltprint specifically) and thin enough to allow for good contact, but there was still a fair amount of exposure on the masked frame. So I guess I need something opaque but I'm wondering about thickness and maintaining good contact pressure. I know it must work as I see examples herein, but need more info on materials. thanks.
The only trouble with doin' nothing is you can't tell when you get caught up
If you don't have an arts supplier, you can find it on the internet and have it shipped.
Gandolfi - I am in awe of your work - superb!
