Abstract
PURPOSE:To manufacture a gradation original negative of high quality by a simple device with high precision, by performing exposure at the original surface position of a process camera while a gradation slit is moved at a constant speed. CONSTITUTION:For example, a device is used which consists of substrate 5 to be placed on the original surface of a process camera and a flat plate through which light is not penetrated and is provided with mask plate 1 provided with slit 6 and driver 3 (consisting of motor 3a and linear head 3b and moves up and down on mask plate 1 along guide rails 4 and 4 provided to the substrate) which moves mask plate 1 at a random constant speed. Substrate 5 is equipped and a raw stock and contact screen are equipped in the process camera. Then, after the lower end part of slit 6 is aligned to the upper end part of milk-white plate part 2, exposure is performed while plate 1 is lowered at a constant speed until the upper end part of slit 6 passes by the lower end part of part 2. Thus, the gradation original negative of high quality and high precision can easily be obtained.
