세라믹 안료를 이용하여 제품을 채색하거나 장식하는 도자산업의 경우 색채 재현을 위해 안료의 농도에 의한 색상과 색조변화를 체계적으로 분류하여 표준화한 기준이 없어 세라믹 안료를 적용하는 색채관리가 필요하였다. 본 연구는 도자산업에 일반적으로 이용하는 빨강, 파랑, 노랑계열 무기안료의 물리적, 화학적 특성 분석을 위하여 부피비중, 평균입도, 결정상, 화학성분, 비표면적 측정을 실시하였고, 투명유와 혼합하여 고온 열처리 후 색도분석으로 CIEL*a*b*값과 Munsell H V/C 및 반사율을 산출하였다. 안료 혼합은 Munsell System에 적용되는 Green계열, Purple계열, Yellow-Red계열로 색상의 범위를 넓히고자 하였고, 안료 2종 혼합의 발색을 예측을 위해 Kubelka-Munk이론을 적용하였다. 안료의 첨가량에 따른 흡광율 변화로 안료 포화도를 판단하였다. 빨강 안료의 첨가량이 7wt%, 노랑 안료 9wt%, 파랑 안료 3wt%부터 흡광율이 포화를 이루는 평탄역을 나타냈다. 안료 R-1과 Y-1의 혼합 색채는 vivid R계열과 soft, YR계열로 발색 하였고, 안료 R-1과 B-1의 혼합색채는 pale, soft, vivid PB계열로 발색하였다. 안료 R-1과 Y-1의 혼합 색채는 soft YR계열과 vivid R계열로 발색하였다. 발색한 2차 색상은 Munsell System의 Green계열, Purple계열, Yellow-Red계열에 분류하였고, pale, soft, 기본색, dull, vivid톤으로 영역을 확장하였다.

In case of ceramic industry that decorates products with ceramic pigments, there is no standardized criteria that systematically classifies colors and color changes by concentration of pigments for recreation of colors, so that it is necessary to have the color management system applying ceramic pigments. In order to analyze physical/chemical characteristics of red, blue and yellow group inorganic pigments generally used in ceramic industry, this study measured density, average particle size, crystalline, chemical compound and specific surface area. After mixing them with clear glaze and then conducting high-temperature thermal treatment, the CIEL*a*b*value, Munsell H V/C and reflection were calculated through chromaticity analysis. Regarding pigment mixture, we aimed to extend the range of color to green, purple and yellow-red groups applied to Munsell System. The Kubelka-Munk theory was applied to predict color of mixture of two-types of pigment. With the changes of absorption depending on the amount of added pigments, the pigment saturation was determined. We observed the plateau showing saturation of absorption from the addition of 7wt% red, 9wt% yellow, 3wt% blue pigments. The color mixed with pigment R-1 and Y-1 was colored as vivid R group, soft, YR group while the color mixed with R-1 and B-1 was colored as pale, soft, vivid PB group. The color mixed with pigment R-1 and Y-1 was colored as soft YR group and vivid R group. Those 2nd colors were classified into green, purple and yellow-red groups, and it was extended to pale, soft, basic, dull, and vivid tones.
