Abstract: 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.

Abstract: A first humidified gas is supplied through a first supply port to a sheet. A second humidified gas is supplied to a space where nozzles of an inkjet recording head are exposed through a second supply port located at a position closer to the recording heads than the first supply port, to increase atmosphere humidity in the space. The sheet portion having a moisture content increased by the humidification in advance is advanced into the space having the increased atmosphere humidity, to record on the sheet using the inkjet recording head. An amount of humidification with the first humidified gas is set according to at least one recording condition.

Abstract: A waiting time Ts is decided on the basis of ink type information and ink feed amount information, referring to waiting time table A (Step 6). Along with this, a dried printing paper is carried to and stopped in a waiting area 9 (Step 7), a time period T is measured after stopping, and measurement processing in the next step is delayed until the time period T reaches the waiting time Ts. Then, when the time period T reaches the waiting time Ts, a measuring instrument 10 is used to measure a density of a patch printed on the printing paper (Steps 8 and 9).

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.

Abstract: A cut mark is recorded in an area between one image and the next image to be printed, and the recorded cut mark is to be detected. When the cut mark cannot be detected, a position of the cut mark is estimated based on information on an already detected cut mark and information on a length of the image printed after said already detected cut mark. A first cut position and a second cut position for cutting off the area are set based on the estimation.

Abstract: A first reading unit that reads a pattern or an image formed on a sheet by a print unit for recognizing a print unit state, a second reading unit that reads a cut mark formed on the sheet on a downstream thereof, a cutter that cuts the sheet on a downstream thereof, and a reverse unit that reverses the sheet fed to the print unit again are provided. In duplex printing, the sheet where images are sequentially printed on a first surface is led to the reverse unit, the front and rear faces are reversed, and the sheet is fed to the print unit again. The sheet where images and cut marks are sequentially printed on a second surface is cut by the cutter for each piece and discharged. The sheet is cut on the basis of a reading of the cut mark by the second reading unit.
