    摘要: There are provided an inkjet printing apparatus and an inkjet printing method, whereby, the temperature of a print head is controlled and the ejection volume of ink to be ejected is stabilized to print a high-quality image, even at a high printing duty. Based on print data, an ejection number of ink to be ejected into a unit printing area is counted. The print head is heated to a target temperature that is raised in consonance with an increase in the count value.

    摘要: To achieve high-quality printing by controlling an ink-travelling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink is landed on a desired position of the printing medium effectively without disturbing the ink ejection, independent of a difference in the thickness of the printing medium. An electric field between a printing head and the printing medium is generated by applying a voltage to a platen of conductive material positioned immediately below the printing medium. At this point, the voltage applied to the platen is adjusted so that the electric field of a preferable intensity can be generated on a face of the printing head where ejection openings are formed irrespective of the thickness of the printing medium.

    摘要: An objective of this invention is to suppress an increase in power consumption and reduce ink density unevenness caused by variations in the amount of ink discharge upon performing printhead temperature retaining control. To achieve this objective, a printing apparatus according to the invention which prints on a print medium by scanning a printhead with a printing element for generating thermal energy has the following arrangement. That is, the printing apparatus includes a determination unit which predicts a maximum temperature which the printhead reaches in printing, and determines a target temperature based on the predicted maximum temperature, and an adjustment unit which adjusts the temperature of the printhead in printing to the target temperature.

    摘要: A printer having storing means storing time information indicating the time at which cleaning operations were last performed, with the initial value of time information stored in the storing means being set to a time later than the shipment of the printer. Elapsed time between the time information stored in the storing means and the current time is calculated when a user gives the printer an instruction to start printing operations. The printer performs suitable cleaning operation for a case wherein the calculated value of the elapsed time is negative.

    摘要: To reduce the data processing load on a recording apparatus, an information processing apparatus and the recording apparatus cooperate to correct registration errors. The information processing apparatus divides a recording area of the recording apparatus into a plurality of partial areas and makes a first correction on a recording position of image data for each partial area; the correction is made for color data items and in pixels. The information processing apparatus generates image data that conforms to the corrected recording position, as well as setting information for controlling the recording apparatus to record the image data. The recording apparatus makes a second correction on the recording position of the image data in fractions of a pixel based on the setting information generated by the information processing apparatus and controls recording of the image data based on the corrected recording position.
