The price rose 3p to 114p as a string of deals were struck in the last half-hour of trading.
Ricoh, the Japanese photocopier maker and 29 per cent shareholder, is seen as the most likely bidder, although Inchcape was once again rumoured to be casting an acquisitive eye over the group.
One dealer said Inchcape's rising share price over the past three years had put it in a strong position to mount an aggressive paper offer.
Shares in Inchcape, down 2p to 596p yesterday, have more than trebled in value since March 1990 while Gestetner's have fallen steadily from 230p over the same period.
Besides the bid talk, another trader said that Gestetner might have finally found a buyer for its Vivitar and Hamimex camera businesses, which it recently failed to sell for pounds 34m to Concord of the US.
Gestetner was one of few talking points yesterday, which saw just 423 million shares traded, with many dealers taking an extended holiday.
