  • Currently, environmental contaminants that can cause Aromatic types of hydrocarbons, less than 1% made of Aromatic Free kind of used products, soybean oil products with linseed oil with the products, rice products using a wide range of environmentally ecological ink since 2000 is released quickly. All materials used in printed material, if the green is the best way to print the composite materials in industrial applications, because each process on the print quality and productivity, there can be many differences in this experiment because it accounts for a large proportion in the print general ink in the ink section and the International color standards(ISO2846-1:2006) certified ecological ink were compared. Therefore, in this paper has the ink released from the same company, each common general ink and ecological ink in the same condition which results were focused on whether the emerging international color standard(ISO 2846-1:2006) recognized for environmentally ecological ink printed color reproduction of the actual offset(color reproduction) how conformity to ISO 12647-2 standard color on the basis of the offset would check Color Reproduction. Based on the results of the experiments of this study, given the ecological ink coated paper, uncoated paper both color difference and the gamut of the ISO 12647-2 standard is suitable for ecological ink, the ink's color gamut reproduction, even more than existing international standards, there is no confirmed that the correct color reproduction possible. Using environmentally ecological ink industries is expected to respond to environmental policy.

  • Low-emissivity (low-e) coatings with visible transparency have attracted increased interest m reducing heat radiation loss through window panes from ecological and sustainable aspects. $TiO_2$-silver transparent thin films for low-e have good properties for UV and IR blocking as well as photocatalyst compared to that with commercial UV blocking films such as fluorine doped oxide (FTO), antimony doped tin oxide (ATO), etc. In this study, transparent $TiO_2$-silver thin films were prepared by successive ink-jet printing of commercial nano silver and $TiO_2$ sol. The $TiO_2$ sol, as ink for ink-jet printing, were synthesized by hydrothermal process in the autoclave externally pressurized with $N_2$ gas of 200 bar at $120^{\circ}C$ for 10 hrs. The synthesized $TiO_2$ sols were all formed with brookite phase and their particle size was several to 30 nm. At first nano sized silver sol was coated on glass substrate, after that $TiO_2$ sol was coated by ink-jet printing. With increasing coating thickness of $TiO_2$-silver multilayer by repeated ink-jet coating, the absorbance of UV region (under 400nm) and IR region (over 700nm) also increase reasonably, compared to that with commercial UV blocking films.
