Print labels for the dials and reverse them on the x-axis, so they read backward. Use a toner printer, not inkjet. Tape in place and apply a solvent, like acetone. Push against the paper with moderate pressure. The ink should adhere to the wood.

Apply Protective Coat

Brush a protective coat over the wood to preserve the ink and finish.
