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.

Inkjet printing apparatus, control method therefor, and storage medium

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.

Printing apparatus, control method, and storage medium

An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.

Inkjet printing apparatus and inkjet printing method

To provide a technology capable of appropriately suppressing deterioration in cutting accuracy of a slitter although the rigidity of a print medium changes, a printing apparatus is equipped with: a first conveyance unit configured to convey a print medium; a printing unit configured to print an image by applying ink to the print medium conveyed by the first conveyance unit; a cutting unit disposed on a downstream side in a conveyance direction in which the print medium is conveyed by the first conveyance unit and configured to cut the print medium, which is conveyed by the first conveyance unit, along the conveyance direction; and a second conveyance unit disposed on the cutting unit, and the printing apparatus includes a correction unit configured to correct a parameter related to conveyance of at least one of the first conveyance unit and the second conveyance unit, based on information about the print medium.

Printing apparatus, control method, and conveyance apparatus

An object is to provide a full-line inkjet printing apparatus and a printing method that can suppress occurrence of image degradation in the case where a conveyance roller conveys a print medium and multipass printing is performed. The maximum conveyance amount in a return route is set to be smaller than a distance between the conveyance roller and a print head.
