- laying down the color first, then covering with black, then engraving to create depth.
- creating the design in black, then engraving, then tinting with progressive layers of weak ink
- doing both the above: color, then black, then engrave, then more color or black, then engrave.
I actually am finding this more difficult than straight engraving on a black board. We shall see. I seem to be having trouble with values so far. Stay tuned.
