摘要： An object of the present invention is to provide a printing apparatus and a printing method even with a variation in the temperature of a print head, thus keeping the quality of images resulting from printing high. Adjustment patterns used to adjust the difference in ink ejection timing between ink ejected in a forward direction and ink ejected in a backward direction during scanning are printed at a plurality of different temperatures. Adjustment values for the ink ejection timing at the respective temperatures are selected from the adjustment patterns. Then, the correction value for the ink ejection timing is calculated from the adjustment values based on the temperature detected by the detection device. Printing is then performed with the difference in ink ejection timing between the ink ejected in the forward direction and the ink ejected in the backward direction during scanning, adjusted based on the correction value.

摘要： An inkjet printing apparatus, a maintenance method and an inkjet printing system which are capable of precisely calculating the amount of satellites or ink mist generated and replacing a collecting mechanism at most appropriate time. The inkjet printing apparatus has a wind-powered collecting mechanism collecting generated sub-droplets such as satellites or ink mist, and head temperature sensors for obtaining temperature information of the print head. The CPU calculates the amount of sub-droplets generated on the basis of printing conditions including the detected temperature information of the print head. The CPU determines whether the replacement of the wind-powered collecting mechanism is necessary on the basis of the calculated amount of sub-droplets generated.

摘要： There is an object of providing a printing apparatus which can restrict a variation in ejection characteristic of an ink droplet due to a temperature change of a printing head to restrict degradation in an image. The printing apparatus adjusts temperatures of the print head to first and second temperature so as to measure ejection characteristics of the print head at the first and second temperature. Then, a driving condition is generated based on the measured ejection characteristics and a printing is performed based on the measured ejection characteristics.

摘要： A printing apparatus includes a print unit, an acquisition unit, and a setting unit. The print unit performs printing on a sheet by repeating reciprocating scans of a print head. The acquisition unit acquires information on a temperature of the print head. The setting unit sets a wait time to start a next scan after one scan. The setting unit increases the wait time by a predetermined additional time for each subsequent scan once a value acquired by the acquisition unit exceeds a first threshold, unless the value falls below a second threshold.
