摘要： The present invention allows the detection of ink in a printing head that can be widely applied to various printing systems by significantly simplifying its configuration. There are a heater for supplying an energy to eject ink, a driver for driving the heater, and a detection electrode capable of detecting a voltage variation that arises between the heater and the driver and that depends on the driving of the heater. Furthermore, an insulating film that covers the surface of the detection electrode protects the detection electrode from chemical or physical change. Furthermore, a reference element group or a reference unit that produces a signal as a reference of the detection signal avoids the influence of noise. Furthermore, an energy-generating element and another signal source improve the accuracy of ink detection. A drive pulse which is insufficient to eject ink may be supplied to the heater to improve the accuracy of ink detection.

摘要： An inkjet printing apparatus is adapted to use a non-contact method for detecting the presence and the amount of liquid, in the form of ink droplets discharged from a printhead or ink tank, using electromagnetic waves in the form of infrared rays. The apparatus and method employ an infrared sensor to detect infrared radiation emitted by the ink in proportion to the amount of ink present. The apparatus and method further employ one of various shielding members to prevent the intrusion of infrared radiation noise into the infrared sensor field of detection, and, in some aspects, a fan to control air flow within the field of detection. The result is less noise in the detection signals of the infrared sensor, and therefore a more sensitive and more reliable liquid detection method and liquid detection apparatus.

摘要： An ink jet printing method prints an image on a printing medium by ejecting ink and printabilty improvement liquid containing a substance for improving printablity of the ink to the printing medium. At this time, ejection of the ink and ejection of the printability improvement liquid onto the printing medium are achieved such that the position where the printability improvement liquid is applied and the position where the ink is applied are different from each other, but partially overlap when the ejected printability improvement liquid comes into contact with the ejected ink on the printing medium.

摘要： An ink-jet recording apparatus ejects droplets of a recording-improvement liquid on a boundary line between two different color portions of an image by using an ink-jet recording head. The ink-jet recording head comprises a group of nozzles for ejecting the recording-improvement liquid which is responsible for precipitating or condensing a coloring substance in the ink. Accordingly, a high-quality image that comprises black-color portion with a high image density without causing any feathering and multiple-color portions without a spread of ink can be obtained.
