Springform cake tins have a detachable base. Because of their structure, they are not easy to line in the traditional way, so try the following.
Remove the outside ring. Cover the base section with baking parchment or greaseproof paper, leaving a wide margin around the edge. Then clip on the outside ring. Next trim off the excess paper from the outside. Finally, line the sides of the tin in the usual way with parchment or greaseproof paper.
