Where I live we have good waves and so, many surf boards makers.
I used "stickers" from a local printer. Made over rice paper. I think (not sure) acrilyc painted (serigraphyed)
Results: The paper wetted nicely, but not completely transparent. Used epoxy resin.
The ink / paint is not completely permeable to resin. So, small voids appeared between ink and outer surface (clear gel coat).
Results are nice with PE. Ask the surfboards makers, they are using stickers succesfully for decades.
