초록

레이저 프린터에 의해 만들어진 인쇄물 및 활자는 토너 박막과 종이 사이의 계면력에 따라 그 품질과 신뢰성이 크게 좌우된다. 현재 토너 박막의 계면력을 측정하기 위한 방법은 peel-off test로써 이는 토너 박막의 표면 특성, 테이프의 점착특성, 그리고 실험을 수행하는 작업자의 성향과 같은 여러 복합인자들에 따라 측정되는 계면력 특성이 변한다는 문제를 가지고 있다. 따라서 본 연구에서는 peel-off test에서 측정된 계면력에 영향을 미치는 주요인자에 따른 토너 박막의 계면력과 박리 정도의 기여도를 다구찌 실험계획법을 사용하여 알아보았다. 그 결과, 토너 박막의 계면력은 주요인자들의 수준이 커질수록 그 영향력이 크게 증가하지만 토너 박막의 박리 정도는 그렇지 않았다. 또한, 본 연구의 주요인자들에 대한 조건에서 가장 큰 기여도를 가지는 인자는 시편의 이송속도로 나타났다.

In printing systems, the reliability of printed material depends on the ability of the toner film to remain adhered to the paper surface. In order to measure the strength between the toner film and the paper surface, a peel-off test is often performed. After conducting the test, the amount of toner film remaining on the paper is measured in order to determine the interfacial strength. The results of this test can be affected by many factors such as the peeling rate, weight of the roller used, and dwell time of tape. Sensitivity analysis was performed with respect to peeling rate, weight of roller and dwell time of tape at different levels. It was found that the interfacial strength increased with an increase in these main parameters. On the other hand, the trend with respect to the percentage of toner loss was different. Further, the interfacial strength and percentage of toner loss were significantly affected by the peeling rate.
