摘要： Density unevenness accompanying a variation in an ejection characteristic of each nozzle is reduced without worsening granularity of an image. To this end, an image processing apparatus generates first corrected data by correcting image data by using a first correction table common to the plurality of nozzles. Further, the image processing apparatus generates second corrected data by correcting the image data by using a second correction table for each of the plurality of nozzles. Furthermore, the image processing apparatus generates first quantized data by quantizing the first corrected data and generates second quantized data by quantizing the second corrected data. After that, the image processing apparatus generates N-valued print data based on the first quantized data and the second quantized data.

摘要： There is provided a liquid consuming apparatus including: a tank having a liquid storing chamber, an erected wall through which the liquid inside the liquid storage chamber is visible from outside of the tank, and an inlet which is formed to penetrate through the erected wall and via which the liquid is poured into the liquid storage chamber; a liquid consuming section which consumes the liquid stored in the liquid storing chamber; and a cover. A transmitting section and a checking section are formed in an upper surface, of the cover, under a condition that the cover is in the exposure position, the transmitting section configured to transmit information optically to a user of the liquid consuming apparatus and the checking section configured to prevent the liquid moving on a particular surface of the cover from arriving at the transmitting section.

摘要： Provided are a printing result inspection apparatus, a method, and a program capable of determining a printing defect caused by a printing step and a printing paper defect caused by printing paper by reading the printing paper once. A defect determination unit determines whether defected regions extracted from a non-image region are the printing defect or the printing paper defect based on a density change amount and a color, and an image feature amount of a defected region determined as the printing paper defect in the non-image region is stored in paper defect information and is accumulated in a paper defect information storage unit. Next, the defect determination unit determines whether defected regions extracted from image regions are the printing defect or the printing paper defect based on the paper defect information.

摘要： A direct-to-object printer includes a vaporizer to attenuate the effect of oxygen inhibition on the curing of non-aqueous ultraviolet (UV) marking material ejected onto the surface of an object printed by the printer. The vaporizer includes a heating element to form a vapor from a solution of solvent and particulate and a pressurized air source to direct the vapor toward the object to enable a portion of the vapor to condense on the object. The condensed vapor forms a barrier that attenuates the effect of oxygen inhibition on the curing of non-aqueous UV marking material.

摘要： A liquid circulation apparatus includes a main tank that stores a liquid, an upstream tank connectable to an upstream side of an inkjet head, a downstream tank connectable to a downstream side of the inkjet head, a pump configured to supply the liquid from the main tank at an amount larger than a sum of an amount of liquid passing through the inkjet head and an amount of liquid ejected from the inkjet head. The upstream tank includes a first upstream liquid chamber configured to be at a hydrostatic position higher than a nozzle of the inkjet head and connected to the pump, a second upstream liquid chamber configured to be connected to the inkjet head, and a third upstream liquid chamber connected to the main tank. The downstream tank includes a first downstream liquid chamber configured to be at a hydrostatic position lower than the nozzle.

摘要： A recording apparatus includes a housing body, an opening/closing member, attached to the housing body via a pivot shaft so as to be capable of rotating freely, that covers the surface of the housing body on one side thereof, and an ink tank having an injection port for filling an ink holding chamber with ink used in recording. Here, the ink tank is disposed so that one end thereof is positioned within the housing body on the opposite side of the housing body as the side in which the pivot shaft is provided, and has a stepped shape including a step portion, the step portion being provided on a side of the ink tank that is further from the pivot shaft. The injection port is provided in the step portion, and when the opening/closing member is opened and the ink is to be filled.
