Engraved Plastic + Black Crayon = High Contrast Panels
February 23rd, 2011 link to (permalink)
Effective, easy, inexpensive process from Briton James Williamson. James starts with laser-engraved panels, rubs them with black crayon, and removes the excess by buffing with paper soaked in mineral spirits. A few minutes in a low-temperature oven seals the deal. Nice work, James!
