Abstract

PURPOSE:To realize a stable color separation for a reflective original having a picture containing a fluorescent material, by irradiating the light of an original light source to the reflective original attached to an original cylinder of a plate making color scanner via an ultraviolet ray absorbing filter and then performing the scanning. CONSTITUTION:A reflective original 2 is attached to an original cylinder 1 of a plate making color scanner, and an ultraviolet ray absorbing filter 4 is put between a light source 3 for reflective original and the original 2. Then the light containing ultraviolet rays led out from the light source 3 is led to the filter 4 through a lens 5 and irradiated on the original 2 after eliminating the ultraviolet rays. Then the scanning is carried out, and the reflected light is led to a light receiving part 6 of the plate making color scanner. As a result, no fluorescent light is delivered from the original 2 to realize a color separating under the separating conditions substantially equal to the separating conditions of an ordinary color film.
