Abstract: An ink jet recording apparatus of a line-recording-head type includes one or more recording heads using the same ink and performs recording of an image by conveying a recording medium using multiple passes through a recording region of the recording head while the recording medium is repeatedly conveyed backward and forward to speed up recording and improve image quality. A recording head is controlled to provide that an amount of ink applied to a recording medium in a case where the recording medium is conveyed at a first speed is smaller than an amount of ink applied to the recording medium in a case where the recording medium is conveyed at a second speed higher than the first speed in both of a case where the recording medium is accelerated and a case where the recording medium is decelerated.

Abstract: A printing apparatus includes a printing unit configured to print an image on a print medium, an acquiring unit configured to acquire temperature information of the printing unit, and a control unit configured to control the printing unit so as to start relative scanning in a case where a temperature that is indicated by the temperature information has reached a print permission temperature. The print permission temperature in a first print mode whose speed at a time of a constant speed in relative scanning is a first speed is a first temperature. The print permission temperature in a second print mode whose speed at the time of the constant speed is a second speed that is faster than the first speed is a second temperature that is lower than the first temperature.

Abstract: A recording apparatus includes a recording unit, a scanning unit configured to perform relative scanning by moving the recording unit and a recording medium relative to each other at least once with respect to a unit region on the recording medium, a recovery unit configured to perform a recovery operation for maintaining or recovering a recording performance of the recording unit for application of a recording material, and a control unit configured to control the recovery unit, wherein the control unit acquires recording mode information about recording of an image to be performed on a recording medium for (n+1)-th page (n being a natural number) and determines, based on the acquired recording mode information, whether to perform an inter-page recovery operation at timing after recording of an image on a recording medium for n-th page ends and before recording of an image on a recording medium for (n+1)-th page starts.

Abstract: An inkjet printing apparatus includes a print head configured to print an image on a printing medium using a printing element configured to eject ink with thermal energy, a scanning unit configured to cause the print head to scan the printing medium, and a control unit configured to control scanning by the scanning unit and image printing by the print head based on an image printing instruction, wherein the control unit performs a control operation including executing a preliminary ejection to eject, from the print head, ink that does not contribute to image printing before an image is printed in one scanning operation, and determining an amount of ink to be ejected in the preliminary ejection based on a difference between a target temperature and a scanning start temperature, which is a temperature of the print head acquired in response to an instruction to start the one scanning operation.
