20120204756 | NON-AQUEOUS INK - A non-aqueous ink including at least a pigment and an organic solvent, wherein the organic solvent includes at least one ester solvent selected from a phosphoric acid ester solvent, a boric acid ester solvent and a silicic acid ester solvent by an amount of 50 mass % or more, and a content of a polymer component in the ink is 20 mass % or less relative to the pigment. | 08-16-2012 |
20120210908 | OIL-BASED INKJET INK - An oil-based inkjet ink includes at least a pigment, a dispersant and an organic solvent, wherein a calcium content in the ink is 8 ppm or less, and a magnesium content in the ink is 3 ppm or less. | 08-23-2012 |
20130135397 | INKJET RECORDING APPARATUS - When a non-aqueous ink having a high density is used, a physical quantity defined as “density/viscosity” is equal to or more than a reference value, and therefore printing on a recording sheet is performed using a drive signal with a waveform for suppressing a residual vibration of the ink. Likewise, as to an ink having a low density, when the viscosity of the ink is low, the physical quantity is equal to or more than the reference value, and therefore printing on a recording sheet is performed using the drive signal with a waveform for suppressing a residual vibration of the ink. On the contrary, when the physical quantity is less than the reference value, printing on a recording sheet is performed using the drive signal with a normal waveform. | 05-30-2013 |
20130233203 | NON-AQUEOUS INK - [Problem to be solved] A non-aqueous ink, which has excellent pigment dispersion stability and can achieve reduction or elimination of print-through, thereby achieving high print density, is disclosed. | 09-12-2013 |
