Abstract
A thermal activation device has a thermal head having heat generating elements for thermally activating a heat-sensitive adhesive layer of a heat-sensitive self-adhesive sheet. The heat-sensitive self-adhesive sheet has a sheet-like substrate having a printable surface on a first side thereof and the heat-sensitive adhesive layer on a second side thereof. An energy control device controls the thermal head by applying one or more voltage pulses to the heat generating elements for energizing the heat generating elements to thereby thermally activate an area of the heat-sensitive self-adhesive layer in one step. When a series of the voltage pulses are applied to the heat generating elements, the energy control device selectively switches between the heat generating elements to be energized by the voltage pulses each time one of the voltage pulses is applied.
