The effect of wettability of deinking agents which formed with various nonionic surfactants against the pulp fibers and ink particles were studied, And the effect of flotation processes on the deinking were also investigated. The wettabilities of the deinking agents against the water and ink particles were measured by Washburn tube and sessile drop techniques, respectively. As the water absorption increased (i.e., hydrophilicity increased), the ink removal increased, which indicates that the ink removal is strongly affected by the detachment process due to the swelling of the pulp. Also, when the contact angle of air/ink/deinking agent increased, the hydrophobicity of the ink particles increased, the efficiency of the ink removal and the brightness increased.

The color difference between original and printed copy is affected mainly by ink trapping and optical properties of overprinted ink layer. Since the general expression itself about ink trapping is affected also by the optical properties, the analysis of color difference using the ink trapping only cannot be certain. This study will show a new approaching method for optical analysis of spectral reflectance and the effect of printing sequence on color difference in multi-color overprints under the condition of excluding completely the ink trapping problems by means of using transparent film as a substrate.

The metal films ink-jetted using the conductive ink based on a mixture of copper and silver nanoparticles were investigated. The porosity and resistivity of films were minimized by adjusting the mixing ratio of Cu and Ag nanoparticles. We demonstrated that the printed tracks with good conductivity could be obtained at sufficiently lower annealing temperatures where plastic substrates could be used.

We studied ink-jet printing for selective deposition of soluble oxide semiconductor to fabricate transistor. Sol-gel derived ZTO solution was synthesized for ink-jet printable solution. Transistors were produced by printing oxide layer between ITO electrodes. We demonstrated that ink-jet printed ZTO transistors work well and surface treatment significantly influences device performance.

Success in moving ink jets into newer areas such as printing on to-be-defined flexible substrates or developing new functional fluids requires both process and fluid research and engineering. Today, leading-edge concepts are slow to be explored because of the expense and complexity of commercially available ink jet deposition systems, time and resources required to specify and acquire commercial ink jet systems and the expertise required to operate commercial ink jet systems.

Several methods are available for the fabrication of electrode pattern for the plasma display panel(PDP) including screen printing and photolithographic method. Piezo type ink-jet printing method is considered to the method of choice for electrode patterning in manufacturing of PDP. Both silver ink and absorbent layer paste formulation were developed for ink-jet printing of electrode pattern. The ink-jet printing of silver electrode with preformed absorbent layer was especially suitable for the patterning of address electrode for high resolution PDP.

Zinc tin oxide (ZTO) sol-gel solution was synthesized for ink-jet printable semiconducting ink. Bottom-contact type TFT was produced by printing the ZTO layer between the source and drain electrodes. The transistor involving the ink-jet printed ZTO had the $mobility\;{\sim}\;0.01\;cm^2V^{-1}s^{-1}$. We demonstrated the direct-writing of semiconducting oxide for solution processed TFT fabrication.
