Gallery: 1931Chrysler


During 2002, I struggled with the art for this car, particularly with the pinstriping (1/8 inch on the car, 0.0035 inch/0.25 point on the glass).  Late in the year, I had some success, primarily by switching to UltraPro 4 mil, from 3 mil, and by some subtle changes in design and blasting. 


The use of the original UltraPro Blue 4 mil required some changes in process and technique to be successful.  Removing the carrier sheet was a problem; the substrate bond benefits from an overnight cure, and it seemed to generate more bubbles, but be bothered by them less.  Curious. 


Design changes included leaving space unblasted internal to the blast area.  By not removing and blasting the resist between the pinstripes, they seem to separate visually.  Since the image is not deeply carved, the extra "black space" on the image helps.



Time to do art: about five hours

Time to blast: about 45 minutes, including peeling
