친수성의 도공층을 갖고 있는 컬러 잉크제트 용지의 특성을 동적주사 흡액측정, 망점의 화상해석 및 도공층 표면을 주사 전자현미경(SEM)으로 관찰하여 검토하였다. 비잉크제트 용지와 도공지에 비하여 잉크제트 용지는 단시간 동안에 현저한 표면 흡액특성을 나타내었지만 그 특성은 제품에 따라 다르게 나타났다. 망점 특성으로부터 평가한 잉크 방울의 흡수시간은 망점의 면적과는 상관관계를 나타내진 않았으나 진원도와는 부의 상관관계를 나타냈다. 즉 빠른흡액특성은 원형의 망점을 형성하는데 유효하였다. 광택 처리제품과 광택처리를 하지 않은 제품을 비교할 경우 광택처리 제품의 진원도가 낮게 나타났는데 이것은 주사전자현미경의 관찰 결과로부터 도공층을 칼렌더 처리할 때 발생하는 할열 때문인 것으로 나타났다.

Textile printing prints around twenty bilion linear meters of textile each year. Rotary and flat bed screen printing requires pre and post treatments, leading to the loss of dyes and the environmental problems due to effluents. Digital ink jet printing can offer a solution to the existing problems, especially the environmental problems, in addition to its flexibility. Pigments are used as a dispersion inks in the digital inkjet textile printing. Molecular dynamic simulation like Stokesian dynamic simulation was employed to simulate the behavior of pigments and velocity distribution under the pressure driven flow in the printer nozzle. The simulation shows that the particle distribution in the flow are uniform if particle volume fraction is low, the ratio of nozzle and particle diameter is large, and the dimensionless average suspension velocity is low.

The aim of this reviews is to introduce the information concerning design of the UV-curable jet ink composition in order to provide a good adhesive property on non-porous surface. In order to clarify the viscosity dependence of flying speed for the UV curable jet ink, rheological analysis and observation of the flying state of the ink were carried out. The relationship between ink formulas and adhesive property on non-porous surface was investigated. It was examined the adhesive property of radical polymerization type UV curable jet ink included hydrogen abstraction type photo-initiator, it was expected that the strong adhesive strength can be obtained between the ink and non-porous surface in this study. UV curable jet ink with a slight amount of water was prepared. Optimum ratio of the cationic polymerization type UV curable jet ink shows an adequate adhesive strength towards two kinds of non-porous surface such as glass, poly(vinyl chloride) when tests were conducted on the ink jet-printing test machine.
