Cupping is when the board curves across the width of the board. Looking at the end of the board, it's a smile. When installing the boards, look at the end to see how the grain runs. You should be able to see the growth rings in the board. The shorter rings that were closer to the center of the tree should be on the top of the board. That way if the board cups, it will do in down. That way the board will not hold water, it will run off the sides of the board. You can't really prevent it if a given board is going to cup. Screwing the deck down will help, but screws can pull through the board if it wants to cup.
