  • Publication number: 20200307283
    Abstract: Images with high image quality having less time-difference unevenness are outputted in an inkjet printing apparatus that performs multi-pass printing using full-line inkjet print heads 2. For this purpose, a CPU is capable of setting a first printing method in which an image for a unit area is printed by a specified number of printing conveyance operations and a second printing method in which an image for a unit area is printed by a smaller number than the specified number of printing conveyance operations. The CPU sets conveyance conditions such that a taken time for one printing conveyance operation of the printing conveyance operations for a unit area in the second printing method is smaller than a taken time for one successive printing conveyance operation of the printing conveyance operations for a unit area in the first printing method.

  • Patent number: 10668717
    Abstract: An object of the present invention is to quickly correct a temperature sensor for an ejection head by, both efficiently and in a brief time, estimating a detected temperature of the temperature sensor for the ejection head in a case where the temperature of the ejection head of liquid becomes sufficiently close to an environment temperature. The temperature of a print head 1 is detected by a diode sensor 17 and the environment temperature is detected by a thermistor 10. Based on a change in the detected temperature of the diode sensor 17 at the time of filling of ink for the print head 1, the detected temperature of the diode sensor 17 in a case where the temperature of the print head 1 becomes close to the environment temperature is estimated as an estimated detected temperature. Based on a difference between the estimated detected temperature and the environment temperature, a correction value of the detected temperature of the diode sensor 17 is set.
