Question:  Is the dye sublimation printing process usable for printing snowboards?

Absolutely. Dye sublimation can be used on any surface where polymeric treatment of a substrate can be successful, from mugs to glass to snowboards.

Basis for Dye Sublimation to Work

Because it is the polymers that are the basis of dye sublimation, if a substrate can retain the polymeric treatment on its surface, that substrate can be dye sub printed. Plastics, glass, wood, stone,
