| 20090235843 | Oil Ink Set - The object of the invention is to provide an oil ink set capable of obtaining images having high color reproduction capabilities and high color saturation in particular. The oil ink set of the invention comprises a firsts a second, and a third oil ink having a wavelength region in which the reflectivity of each oil ink on a recording medium changes from 80% to 5% in the wavelength range of 400 nm to 700 nm. In this wavelength region, the reflectivity of the first oil ink is continuously higher than that of the first oil ink, and in the wavelength in which the reflectivity of the second oil ink changes from 80% to 5%, the reflectivity of the third oil ink is continuously higher than that of the second oil ink. Moreover, the coloring materials in the first, the second and the third oil inks are all different. | 09-24-2009 |

| 20140216300 | WATER-BASED INK FOR COMPUTER-TO-PLATE INKJET PRINTING AND PREPARATION METHOD THEREFOR - A water-based ink for use in a computer-to-plate inkjet printing and a preparation method therefor. A polymer of 5 to 40 wt %, an additive of 0.01 to 10 wt %, a dye or pigment of 0.01 to 10 wt %, an organic solvent of 1 to 30 wt %, an anti-foaming agent of 0 to 5 wt %, and deionized water are stirred and mixed at room temperature. When the polymer is dissolved, the mixed solution is filtered. The filtrate is the water-based ink. The water-based ink is sprayed via a computer-to-plate machine onto a surface of a metal substrate (which may be an aluminum plate, a zinc plate, or a copper plate) to form a graphic region. A printing plate allowing for computer-to-plate printing is acquired after solidification. The printing plate acquired is allowed to achieve a halftone dot reproduction rate between 2 and 99% and a recognition rate of 175 lpi. | 08-07-2014 |
