| 20110141177 | Dot Omission Inspection Method Used in Printing Apparatus and the Printing Apparatus - Provided is a dot omission inspection method used in a printing apparatus for forming an image constituted by dots of first and second photo-durable inks. In the dot omission inspection method, an arbitrary image is formed by performing liquid droplet discharge of causing a liquid droplet of the first or second ink to be landed on a medium, performing provisional curing of irradiating the landed liquid droplet using light from a first light source so as to be provisionally cured, and performing main curing of irradiating the provisionally cured liquid droplet using light from a second light source to fix the liquid droplet on the medium. An inspection image is formed without performing the provisional curing on the liquid droplet of the first ink landed on the medium by performing the liquid droplet discharge, and by causing the liquid droplet of the second ink to be landed by performing the liquid droplet discharge at the same position as the liquid droplet of the first ink which is not provisionally cured so as to mix the first ink and the second ink with each other. | 06-16-2011 |

A normal print process including performing liquid droplet discharge of causing a liquid droplet of the photo-curable ink to be landed on a medium, performing provisional curing of irradiating the liquid droplet landed on the medium using light from a first light source to be provisionally cured thereby suppressing flowing of the liquid droplet, and performing main curing of irradiating a liquid droplet provisionally cured using light from a second light source to be fixed on the medium, and an inspection print process including performing the main curing after the liquid droplet of the photo-curable ink landed on the medium by the liquid droplet discharge is not subjected to the provisional curing and is flowed on the medium to increase the surface area of the liquid droplet, are selectively performed. | 06-16-2011 |
| 20110148975 | Dot Missing Inspection Method of Printing Device and Printing Device - A method of inspecting presence/absence of dot missing in a printing device for discharging and impacting liquid droplets of a light curable ink from nozzles onto a medium, irradiating light to the impacted liquid droplets so as to cure the liquid droplets, and forming an image formed of minute dots on the medium includes, at the printing device, discharging and impacting the liquid droplets of the light curable ink from the nozzles onto the medium, irradiating light including a predetermined wavelength component for curing the light curable ink toward the liquid droplets impacted on the medium, at a light receiving unit, selectively receiving the predetermined wavelength component from reflected light of the irradiated light and outputting a received light intensity signal, and determining the presence/absence of the dot missing based on the received light intensity signal output from the light receiving unit and outputting inspection result data indicating the determination result. | 06-23-2011 |

| 20100053244 | LIQUID EJECTING APPARATUS AND EJECTION INSPECTING METHOD - Provided is a liquid ejecting apparatus including: a liquid ejecting head that ejects liquid from nozzle openings by driving of an ejection driving portion; a driving signal generation portion that generates a driving pulse for driving the ejection driving portion; a liquid receiving portion that is disposed so as to oppose a nozzle forming face of the liquid ejecting head and receive ink ejected from the nozzle openings; and an ejection inspecting portion that detects an electrical variation occurring between a conductive portion of the liquid ejecting head and the liquid receiving portion when liquid is ejected toward the liquid receiving portion from the nozzle openings in a state where an electric voltage is applied between the conductive portion and the liquid receiving portion, thereby inspecting whether or not liquid has been ejected from the nozzle openings. The driving signal generation portion generates a normal driving pulse which is used for processes other than an ejection inspection process by the ejection inspecting portion and an ejection inspection driving pulse which is different from the normal driving pulse and is used for the ejection inspection process by the ejection inspecting portion. | 03-04-2010 |
| 20100053249 | LIQUID EJECTING APPARATUS AND EJECTION INSPECTING METHOD - Provided is a liquid ejecting apparatus including: a liquid ejecting head that causes liquid to be ejected from nozzle openings by driving of an ejection driving portion; a driving signal generation portion that generates a driving pulse for driving the ejection driving portion; a liquid receiving portion that is disposed so as to oppose a nozzle forming face of the liquid ejecting head and receive the ink ejected from the nozzle openings; and an ejection inspecting portion that detects an electrical variation occurring between a conductive portion of the liquid ejecting head and the liquid receiving portion when liquid is ejected towards the liquid receiving portion from the nozzle openings in a state where an electric voltage is applied between the conductive portion and the liquid receiving portion, thereby inspecting the ejection and non-ejection of the liquid from the nozzle openings. The driving signal generation portion generates an ejection inspection driving pulse for use in an ejection inspection process by the ejection inspecting portion and corrects the waveform of the ejection inspection driving pulse in accordance with the ambient temperature. | 03-04-2010 |
| 20100060689 | PRINTING DEVICE AND PRINTING METHOD - Provided is a printing device including: a printing unit which has a plurality of nozzles for ejecting a liquid and printing an image; an inspection unit which inspects whether or not the liquid is able to be ejected from the nozzles; and a controller which divides each pixel of image data into a plurality of pixels, and allows the printing unit to perform printing if at least one of at least a predetermined number of nozzles corresponding to each pixel of the image data is able to eject the liquid in the inspected result of the inspection unit, when dots are formed using at least the predetermined number of nozzles with respect to the plurality of divided pixels. | 03-11-2010 |
| 20100060690 | LIQUID EJECTING APPARATUS AND EJECTION INSPECTING METHOD - A liquid ejecting apparatus includes: a head which ejects a liquid from nozzles; a first electrode which charges the liquid with a first potential; a second electrode which is charged with a second potential different from the first potential; and an inspector which inspects whether the liquid is ejected from the nozzles based on a variation in a potential caused in at least one of the first and second electrodes by ejecting the liquid charged with the first potential from the nozzles to the second electrode and which determines whether the inspection of liquid ejection from the nozzles is normally executed based on the variation in the potential during a non-ejection period in which the liquid is not ejected from all of the nozzles. | 03-11-2010 |
