What is a topsheet?
A rubber can consist of a sponge and a topsheet. With a normal inverted rubber, the topsheet is stuck to the rubber with the pimples against the sponge and the smooth side on the outside which is what you use to hit the ball.
If you look at most rubbers, you can see the sponge will be a different colour to the topsheet. The topsheet will be either red or black.
I hope I've explained this so you can understand.
