Here is Rich, from Upstream Boards, applying the graphics before the final fiberglass layer on this nice river surfing board.
The bottom of the board is a mix of fiberglass, innegra, and basalt. It is a very strong composite mix.
This image is after the "hot coat", which is the final layer of resin that is applied over everything to further protect the reinforcing fibers. The idea is that you can get some scratches in this coat and be able to maintain your board before anything touches the reinforcing fibers.
