PURPOSE:To perform data imprinting at correct exposure by supplying the data optical beam from a data imprinter of prescribed quantity of light differing from the quantity of object light to the desensitizing layer coated with a desensitizing material of the transmittance corresponding to the ASA sensitivity of a film. CONSTITUTION:A photosensitive film 32 is provided with a filmlike base 38, and a desensitizing layer 40 which is provided on one surface side of said base 38 and is coated with a desensitizing material having prescribed ASA sensitivity. The data optical beam from a data display device 34 are irradiated to the other side surface side of said base 38. A desensitizing layer 42 coated with a desensitizing material having the transmittance corresponding to the ASA sensitivity of the film 32 exists in the part to be imprinted with desired data in extension to the longitudianl direction of the film 32 so that the data optical beam from the data imprinter assumes correct exposure. Thereby, data are imprinted on the film 32 at the quantity of light adjusted to correct exposure by the layer 42 regardless of the ASA sensitivity of the film 32. |
