The sensor is disposed at the first container to detect a liquid level of the first container in at least two positions different in height and obtain a flow rate of the liquid in the retreat passage based on a period during which the liquid level moves between the positions when the on-off valve is opened and the liquid stored in the first container is transferred to the second container. | 03-17-2016 |
20160075898 | IMAGE RECORDING METHOD AND INK SET - Provided is an image recording method including a step (A) of applying an ink containing a coloring material to a recording medium and a step (B) of applying to the recording medium a liquid composition that causes viscosity increase when mixed with the ink so as to at least partially overlap with an area where the ink is applied. The ink contains resin particles, an anionic water-soluble resin, and an anionic surfactant having a carboxy group, the content of the surfactant in the ink is 1% by mass or more and 8% by mass or less based on the total mass of the ink, and the mass ratio of the content of the water-soluble resin to the content of the surfactant in the ink is 0.3 or more and 5.0 or less. | 03-17-2016 |
20160083603 | RECORDING METHOD, RECORDING APPARATUS, AND INK SET - Disclosed is a recording method including recording which includes attaching a color ink composition, which contains a coloring material, and a reaction solution, which includes an aggregating agent which aggregates components of the color ink composition, to a recording medium in no particular order, in which the color ink composition gives recorded matter with a glossiness at 60° of 60 to 100 when the color ink composition is individually attached to a recording medium with a glossiness at 60° of 80 to 100. | 03-24-2016 |
20160144630 | RECORDING APPARATUS, RECORDING SYSTEM, AND RECORDING METHOD - To apply color ink to a region in which application of a glossiness adjusting liquid is completed, a recording apparatus includes a first application unit provided with a nozzle for ejecting color ink and configured to eject the color ink from the nozzle to apply to a recording medium to record an image on the recording medium, and a second application unit configured to apply a substantially transparent adjusting liquid to the recording medium to adjust a degree of surface roughness of the image formed on the recording medium, wherein after the adjusting liquid is applied to a first region of the recording medium by a predetermined times of relative movement between the second application unit and the recording medium, a relative movement between the first application unit and the recording medium for applying the color ink to the first region is started. | 05-26-2016 |
