Alt-Process Prints from Digital Negatives or Positives

Ah perhaps we have a difference in terminology.

I would regard a size as consisting only of a solution to modify the absorbancy of the paper, whereas gum+dichromate I would consider as forming part of a sensitising coating

Maybe I wasn't clear enough. Did you read my process completely? I coat my WC paper with the gum+bichromate mix, dry it and expose the sized paper (no negative) in my uv printer. This hardens the gum so it can act as a layer of sizing and modify the absorbancy of the paper! So far no negative! I then wash out the dichromate leaving me a WC paper with gum sizing! When this piece of gum-sized WC paper is dry, I sensitize with my pd-feox solution!

Thank you, I hadn't cottoned on properly

Interesting idea -- hang out here long enough and you will definately learn new tricks .. want to give this one a try.

Great print once again ndg! If you don't mind my asking, why the diversion of a digital negative?

In my first attempt, the negative got stuck to the tissue - too much moisture. Luckily, I scan most negatives so I was able to create a dig neg for this print. Also, I couldn't capture it again because the plant had withered badly.

"Petals" - a Carbon Transfer Print

Another form my Flowers series.
9" x 13"
The digital negative is on Pictorico.
The tissue was made with mix of Sumi and India inks.
Final support - fixed out 12 x16 Ilford Art 300 paper.

This is a green tea toned cyanotype from a digital file, printed in Canson 55lbs Vellum.
First try and I'm amazed with the almost zero stain in the paper and the deep chocolate black hue.
As always, much nicer in your hands, with a soft back light enhancing the translucent support:
