초록
도공지의 품질향상을 위하여 도공용 무기안료의 제법개선, 도공액 특성 변화, 도공안료의 표면설계, 도공지 제조의 조업성 등 다양한 측면에서의 연구들이 진행되고 있다. 본 연구는 표면개질한 도공안료와 혼합처리한 도공안료를 이용하여 도공지의 물성 및 인쇄적성을 비교하였다. 도공액 배합 시 도공액의 유동특성과 인쇄특성에 영향을 줄 수 있는 여러 인자들을 일정하게 고정하였고 도공안료의 표면개질 유무에 따른 인쇄특성 변화를 조사하였다. 도공지의 표면은 SEM으로 측정하여 표면개질 효율을 조사하였다. 도공액의 물성뿐만 아니라 도공지의 물성 및 인쇄적성에 대한 비교·평가를 실시하였다. 또한 배합조건을 달리하여 인쇄적성의 효율성을 평가하였다.
To improve the quality of coating paper, many areas, such as the manufacturing process of inorganic pigment for the coating, the property change of coating color, the surface design of coating pigment and the productivity of coated paper, were studied. In this study the physical properties and printability of coated paper were compared with the coating pigment to modify the surface of large particle and the coating pigment to mix together the large and small particles. After the coating color was mixed under the same conditions in order that the coating color has the same rheological property printability, the printability change caused by the surface modification of coating color was investigated. With the surface SEM of coated paper, the efficiency of the surface modification of coating pigment was investigated. The physical property and printability of coating paper, in addition to the physical properties of coating color, were compared and evaluated. Also, the efficiency of printability was evaluated, changing the mixing condition.
