ABSTRACT:
A method of image formation using mask for exposure to form an image on photographic paper is disclosed. The mask is composed of transferred images of the dyes of yellow, cyan and magenta. The spectral absorption peak wavelength of the dye is set in a range close to the wavelength at the maximum value of each of the regular, orthochromatic and panchromatic spectral sensitivities of the photographic paper to be used. In the spectral absorption of cyan of the mask for exposure, the absorbance of the wavelength at the maximum value of each of the regular and orthochromatic spectral sensitivities of the photographic paper to be used, is set at a value not more than a predetermined value. In the spectral absorption of yellow of the mask for exposure, the absorbance of the wavelength at the maximal value of each of the orthochromatic and panchromatic spectral sensitivities of the photographic paper to be used, is set at a value not more than a predetermined value.
