Abstract

PURPOSE: To exactly set up separation cnditions, by providing means for diffusing the light quantity of a luminous flux in the light path between the inlet scanner of a color scanner and an potoelectric transducer or means for enlarging the luminous flux in manufacturing a printing plate by color-separating a color original.
CONSTITUTION: In making a 4-color printing plate of yellow, red, indigo, and black by color-separating color original 14, light from light source 10 passes through original 14 supported on drum 12, pickup lens 16, aperture 18, condenser lens system 20 to optoelectric transducer 22, and a current amplified by ampifier 24 is displayed on photosensitive material 28 on supporting drum 26 of an outlet scanner 26. Drums 26, 12 are synchronously linked. Light diffusing material 32, such as frost glass or concave lens 34 is installed between lenses 16 and 20 of the above apparatus, alternatively lens 16 is moved to obscure the focus, permitting uniform light quantity to be given to transducer 22, stable display to be obtained on material 28 of the display unit, and thus, setup of the separation conditions to be made easily and rapidly.
