Abstract
Disclosed are an activation method and a liquid pressure transfer technique, where a transfer film is supplied to the surface of a transfer liquid and then is activated, capable of continuously performing a precise transfer. In forming an appropriate transfer pattern on the surface of an object by pressing the object from the upper side of a transfer tank, in the transfer tank, a pre-activation guide mechanism that holds both sides of the film, which is supplied with the center position matching the center of the transfer tank, at horizontally equivalent positions of the transfer tank and guides the film to an activation area is disposed. Accordingly, the film is urged to swell up in the thickness direction, and, in the activation area, the film is coated with an activating agent in a state in which the guide action of the film using the pre-activation guide mechanism is cancelled.
