Abstract
PURPOSE: To obtain correct exposure in fixed exposure time and enable the easy forecasting of required printing work amount by changing the radiation intensities of light sources according to the distances between the light sources and the object to be exposed.
CONSTITUTION: At the time of making simultaneous exposure of both surfaces 4, 4' of a printing frame 3 by upper and lower light sources 2, 2', the radiation intensity of the light source 2 for the surface 4 is made to the value weaker by a fixed ratio than that of the light source 2' for the surface 4'. Also, at the time of using the printing frame 3', the intensities of the respective light sources are reversed. In this case, radiation intensity adjusters are incorporated into the respective light sources and the distinction of the use of the printing frames 3 and 3' is sensed by limit switches or the like, thence the radiation intensities of the light sources for the respective exposure surfaces are adjusted to the required values according to radiation distances (d), (d') and (d1), (d1'), whereby the desired exposure is applied to each exposure surface by the exposure of the same time.
