디지털 기술을 이용한 삼색 검(Gum) 프린트

Abstract

The three color gum print conducted in this thesis may be varied according to used pigments, Y, M, C separation negative and working processes. Then, obtain a proper transfer function using Photoshop, which is a digital technology, in order to make Y, M, C pigments and separation proper to Y, M, C separation. Experimental Result 1) As a result of a spectroscopic analysis of the three pigments of Y, M and C, the Y pigment was permanent yellow pigment, the M pigment was opera pigment, and the C pigment was mixture that Prussian blue pigment an ultra marine pigment were mixed at the ratio of one to one. 2) I obtained the ATF transfer function, which was a transfer function suitable for characteristics of Y, M, C pigments and Y, M, C separation. In the gum print, I substituted the ATF transfer function for a copy, and then, obtained three color separated copy necessary for the three color gum print. As a result of the above, an effective three color gum print, which reduces variables occurable during the working process, was completed.
