To provide an improved device for exposing sensitometry data and bar code data on a photosensitive medium while avoiding a lot of problems at the time of forming a reference calibration patch into a film using a conventional sensitometry device.
A device for exposing a reference calibration patch on a photosensitive medium, comprising a light source, a plurality of optical fibers corresponding one to one with respect to the elements to be exposed, a collector having an input port for receiving a light outputted from the light source and an output port for transmitting the light to one end of the optical fibers, a plurality of optical attenuators for individually attenuating the light transmitted by each fiber, a projection printing head disposed on the other end of the optical fibers, for directing the light from the fibers onto the photosensitive medium, and a controller connected with the light source for measuring and controlling the optical output from the collector, is provided.
