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
