PURPOSE:To improve the workability of a photosensitive material, and to obtain an image having the excellent color reproducibility by printing the photosensitive material using a filter which contains an oxide of neodymium, vanadium or ruthenium in any position between the light source of a printer and the photosensitive material. CONSTITUTION:The photosensitive material is printed using the filter which contains at least one kind of the neodymium oxide, the vanadium oxide and the ruthenium oxide in any positions of the optical system between the light source of the printer and the photosensitive material. The used amount of said oxide is preferably 1-1,000g, more preferably 100-500g per 1m<2> an optical filter. And, the filter contg. the oxide may be provided in any positions of the optical system between the optical source and the photosensitive material, and preferably between the light source and an original (a color original image). Thus, the positive-positive color photographic image having the excellent color reproducibility can be formed, even in case of using a substractive color process having the excellent producibility of a print working. And, the positive color image having a faithful color reproducibility against various kinds of color images having different color materials respectively, can be obtd. |
