The anti-forcing number of a perfect matching $M$ of a graph $G$ is theminimal number of edges not in $M$ whose removal make $M$ as a unique perfectmatching of the resulting graph. The anti-forcing spectrum of $G$ is the set ofanti-forcing numbers of all perfect matchings of $G$. In this paper we provethat the anti-forcing spectrum of any cata-condensed hexagonal system iscontinuous, that is, it is an integer interval.
