摘要:
A printing apparatus includes a plurality of inkjet print heads to which humidified air is supplied to retain the humidity in the print heads. Ink colors for the plurality of heads are arranged in a sequence corresponding to ink characteristics. The plurality of print heads are arranged in a sequence such that a print head configured to eject ink characterized by having a larger amount of volatile components evaporated within a predetermined time is located in a more upstream area.

A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.

In a line-head type inkjet printing apparatus that ejects a plurality of types of inks, an inkjet printing apparatus is provided in which the change of its ejection properties different depending on the type of ink is prevented from occurring. The line-head type printing apparatus includes an acquisition unit that counts the ejection number of liquid from each of print heads in each of a plurality of print heads. Furthermore, the printing apparatus compares the ejection number of liquid from each of the print heads counted by the acquisition unit with a threshold value set for each of the print heads. The printing apparatus includes a change unit that can move a holder in the main scanning direction when the counted ejection number of liquid exceeds the threshold value set for the print head.

There is provided an inkjet printing apparatus which can output a stable image without density unevenness by performing appropriate drive control to print elements based upon an appropriate representative temperature of a chip whatever image data is printed on a print medium. For this purpose, detection temperatures of a plurality of temperature sensors are lined up in high temperature order, and coefficients by which the respective detection temperatures are multiplied, are determined to be associated with that order at the lining-up, determining a representative temperature by the weighted average method. The common drive pulse associated with to the individual chip based upon the representative temperature thus obtained, to be applied thereto. Thereby even if temperature variations of print elements on the chip exist, it is possible to appropriately control the entire chip in temperature.

A patch is printed on a printing medium, and ink discharge amount information is acquired from a colorimetric value that is acquired by measuring a printed patch. According to the information, color correction is performed on image data to be processed for printing, using a correction table that corresponds to a designated type of printing media.

A printing apparatus that includes printing element substrates which are provided with printing elements that discharge ink. A plurality of temperature sensors, each of which is provided with one of the printing element substrates, measures a temperature of a corresponding printing element substrate. A selection unit selects any one of the temperature sensors, and a determination unit performs a determination operation to determine a state of the printing element substrate based on the temperature measured by the selected temperature sensor in a case when only the printing elements of a substrate that corresponds to the selected temperature sensor are driven. The determination unit performs the determination operation on a first substrate and then on a second non-adjacent substrate.
