옵셋 인쇄용지의 섬유 조성비에 따른 잉크 전이율 변화에 관한 연구 = (A) Study on Ink transfer ratio according to the cellulose fiber composition of offset printing paper

다국어 초록 (Multilingual Abstract)

As result of percent of ink transfer that follows composition rate of offset printing paper, in a case that mixture ratio of 5:5, density is the lowest, and at this point, it confirms the phenomenon that porosity to be most increased.
The smoothness of paper tends to be decrease as content of soft wood fiber downs, and the opacity tends to be most increased as the mixture ratio 5:5, soft wood fiber and hard wood fiber.
The percent of ink transfer is the highest as mixture ratio of 5:5. in this case, it confirms the result following penetration of ink by enlargement of the porosity inside the paper for consider variation of the ink viscosity and print density.
On the other hand, in this particular case, 70% of soft wood fiber and 30% of hard wood fiber is mixed, it confirm the lowest the percent of ink transfer and print viscosity. It is a result following the difference of the density of the paper. So, in the case of off-set print paper to be mixture ratio of 5:5, soft wood fiber and hard wood fiber, it is an advantage of the percent of ink transfer and printability.
