Abstract
A method for exposing a sheet to light radiation while it is under pressure, in which successive portions of the sheet which slightly overlap one another are sequentially clamped between a pressure plate and a light transmitting plate, and are irradiated with electromagnetic radiation through the light transmitting plate in the clamped condition. Further, a device for practicing the method is disclosed, which includes: a light source; a light transmitting plate arranged with the light source on one of its sides; a pressure plate which opposes the other side of the light transmitting plate; a member for relatively biasing the light transmitting plate or the pressure plate towards and away from each other; a device for transporting the sheet passing between the light transmitting plate and the pressure plate; and a control for controlling the light source, the biasing member, and the transporting device, which causes the light source to emit light when the pressure plate and the light transmitting plate are pressed against each other with the sheet between them, and which causes the transporting device to transport the sheet through a distance less than the width of the light transmitting plate, when the light transmitting plate and the pressure plate are separated by more than a certain predetermined distance.
