- Traditional Cyanotype (Bostick and Sullivan kit).
3:2 mix (A:B) - to increase speed. Two drops Tween 20
per 10ml emulsion.
- Mark passed on Sam Wang's (?) suggestion to clear the exposed
paper inverted in a water bath. I add about 5 ml of a 1:100
dilution of Hydrochloric Acid to about 2 liters of clearing
bath to start.
- Remove print, lay on paper towel - lay another sheet of paper
towel on top - remove excess water, dry flat face up.
1) try avoiding Tween
2) try avoiding acid, or give only a 30" first wash, then turn to tap water
3) do you notice bleeding before or after drying?
