Inking up oil matrixes is much easier than inking up bromoils and has the
advantage of using a material with a rather straight characteristic curve.
Hanfstaengl, the last manufacturer of papers for oil printing, went out of
business in 1992. I hope to have a new paper available during the first half of
this year. But as long as the worker knows how to coat a piece of high quality,
smooth paper with a thick layer of gelatin with no air bubbles or streaks ;-),
here are some hints on a good emulsion:
- Prepare 140 ml of a 15% gelatin (Bloom Index >200) solution
- add 14 ml of a 15% potato starch (dextrine) solution
- while stirring, slowly add 14 ml of a hardener, made by mixing 6 ml of a 6%
sol. of acetic acid and 8 ml of a 1% sol. of chrome alum.
Use all solutions at 50 degrees C. Take approx. 50 ml for a sheet of 50x70 cm.
