Title:
連続的色調のカラ−像形成法
Document Type and Number:
Japanese Patent JP2527733
Kind Code:
B2
Abstract:
A process for producing a continuous tone colour image comprising providing a light sensitive photographic element comprising a substrate bearing three imaging media coated thereon, said imaging media comprising: (1) an imaging medium capable of forming a yellow image upon imagewise exposure and processing, (2) an imaging medium capable of forming a magenta image upon imagewise exposure and processing, (3) an imaging medium capable of forming a cyan image upon imagewise exposure and processing, each imaging medium having a maximum spectral sensitivity at a wavelength different from that of the maximum spectral sensitivity of the other imaging media within the range 550 to 900 nm, the sensitivity at the wavelength of maximum spectral sensitivity of the media decreasing in order from the medium of shortest wavelength maximum spectral sensitivity to the medium of longest wavelength maximum spectral sensitivity, the difference in said sensitivities between the media of shortest and longest wavelength maximum spectral sensitivity being greater than 0.8 log exposure units, exposing said element to three independently modulated sources each emitting radiation of a wavelength in the region of the wavelength of maximum sensitivity of a respective imaging medium, the maximum emission intensities of the sources at the wavelength of their maximum output increasing from the source of shortest wavelength to longest wavelength by an amount corresponding to the sensitivity difference of the imaging media, said exposures being conducted in scanning fashion and over a number of discrete exposure levels.
