- 7. A process according to claim 1, wherein the ink, when cured, passes a standard adhesion scratch test according to ASTM D3359.
- 8. A process according to claim 1, wherein the ink, when cured, passes simulated weathering conditions in a QUV tester according to ASTM G 53-88 for approximately 1000 hours.
- 9. A process according to claim 1, wherein the basketball backboard is blow molded polyolefin.
- 10. A process according to claim 1, wherein the basketball backboard is acrylic.
- 11. A process according to claim 1, wherein the basketball backboard is a graphite composite.
- 12. A process according to claim 1, wherein the basketball backboard is dark colored and wherein the process comprises the step of printing a white image corresponding to a reverse black image and thereafter printing one or more color images over the white image.
- 13. A process for screen printing multicolor images basketball backboards comprising:
- (a) positioning a basketball backboard having a printing surface in a screen printing assembly;
- (b) screen printing an image on the printing surface with an ultraviolet light-cured ink, said ink containing a catalyst to impart adhesion and weatherability to said ink when said ink is cured, wherein the catalyst has a concentration in the range from about 5 to about 10%, by weight, of the ink, wherein the image is screen printed with a screen having a mesh size in the range from about 355 to 405 mesh;
- (c) curing the ink with ultraviolet light; and
- (d) repeating steps (a) through (c) to produce a multicolor image on the basketball backboard.
- 14. A process according to claim 13, wherein the ink, when cured, passes a standard adhesion scratch test according to ASTM D3359.
- 15. A process according to claim 13, wherein the ink, when cured, passes simulated weathering conditions in a QUV tester according to ASTM G 53-88 for approximately 1000 hours.
- 16. A process according to claim 13, wherein the basketball backboard is blow molded polyolefin.
- 17. A process according to claim 13, wherein the basketball backboard is acrylic.
- 18. A process according to claim 13, wherein the basketball backboard is a graphite composite.
- 19. A process according to claim 13, wherein the basketball backboard is dark colored and wherein the process comprises the step of printing a white image corresponding to a reverse black image and thereafter printing one or more color images over the white image.
- 20. A process according to claim 13, wherein the image is screen printed with a screen having a plain weave.
- 21. A process according to claim 13, wherein the image is screen printed with a screen having a twill weave.
