Advanced value boundaries

Each control stays on the same 1–254 scale. Moving a boundary changes which parts of the image use each fixed wash value; it does not change the six ink tones themselves.

Black → 4 drop 43

4 drop → 3 drop 85

3 drop → 2 drop 128

2 drop → 1 drop 170

1 drop → white 213

The separated wash values will appear here.
