How long it lasts
None of the sources gives dishwasher, outdoor or scratch figures for copper. Test a sample the way it will be used before you sell it.
What goes wrong
- Roland says primer has no effect on copper, so a primer may not help.
- Alloys and coatings vary, and compatibility is not guaranteed for every metal finish (LogoJET).
Before you print
- Degrease the copper before printing (Roland).
- Test your specific alloy and finish before production (LogoJET).
