On the Color Measurement ot Moist Recording Paper for Echo-Sounder

Abstract

The chemical and electrical characteristics of moist recording paper for echo-sounder was already studied, but color measurement for step input voltage was not yet taken. So we measured tristimulus values (X_2, Y, Z), and plotted Y curve, x-y chromaticity diagram and color difference curve. According to color measurement for five maker's recording papers, we found their characteristics were nearly equal.
