PROCESS
Graining the stone
Once a stone has been printed from for the last time, it is necessary to re-grain the stone to remove the greasy image and enable the stone to be re-used.
Drawing on the stone
There are a range of materials which can be used to draw and paint onto the stone surface, all of which contain grease, which absorbs into the top layer of the stone.

step by step
- Rosin then Talc the image.
- Apply etch (through gum film- DO NOT BUFF). Work from mildest etch to strongest etch.
- Blot up excess etch mixtures.
- Add fresh gum and buff to a thin, streakless film with a cheesecloth.
- Let image rest. 2 hours for dry materials, half a day for liquid materials.
- Wash out the image with mineral spirits (follow with lacquer thinner for stubborn areas).
- Buff down a thin, even layer of asphaltum.
- Let dry.
- Wash off the stone with water and a dirty sponge. Follow with a clean sponge and keep
damp.
- Roll-up the image in roll-up ink until “up” (no asphaltum is visible).
- Rosin and Talc image. Make corrections/deletions if desired.
- Apply second etch (steps 2-4). This can be done immediately after roll up in ink with 2nd & 3rd Etches.
- Let image sit at least 24 hours before printing.
