Image content is printed on a receiver medium using a continuous inkjet printer with a linear printhead having a cross-track printhead width that is wider than the cross-track image width. The linear printhead is characterized to determine an image quality level as a function of cross-track position. A segment of the linear printhead is designated wherein the image quality level within the designated segment of the linear printhead is acceptable. The linear printhead is translated relative to the receiver medium such that the designated segment of the linear printhead is aligned with a region on the receiver medium where the image content is to be printed, and the image content is printed on the receiver medium using the designated segment of the linear printhead.

Provided is an inkjet recording device, including a print head that includes a head base including: a nozzle from which ink is ejected; charging electrodes that charge the ink ejected from the nozzle; deflection electrodes that deflect the ink charged by the charging electrodes; and a gutter that collects ink not used in printing, and a head cover included in the head base, wherein the head base has a first horizontal uneven side portion, an oblique uneven side portion, and a second horizontal uneven side portion.

An ink jet recording apparatus includes a charging electrode that charges ink particles ejected from a nozzle, a deflecting electrode that deflects the ink particles charged by the charging electrode, an operating unit that inputs and sets printing conditions for performing the printing, and a control unit, and the control unit receives a moving distance in a direction in which a printing target is conveyed from the operating unit, calculates the number of non-printing particles on the basis of the moving distance, and performs control for changing to a dot pattern in which the number of non-printing particles are inserted.

A liquid ejecting apparatus includes a carriage that mounts a liquid ejecting head provided with a nozzle surface in which nozzles to eject a liquid are formed, and is configured to move the liquid ejecting head between an ejection area used to cause the liquid ejecting head to eject the liquid onto a medium and a maintenance area used to perform maintenance of the liquid ejecting head, and a liquid receiving portion that has a size equal to or larger than the nozzle surface, is opposed to the nozzle surface located at a detachment position defined in the maintenance area, and receives the liquid discharged from the nozzles when detaching a liquid supply coupling portion detachably coupled to the liquid ejecting head.

The remaining amounts of inks in tanks are obtained, and, based on the obtained results, whether direction for printing an image next is to be inverted with respect to a set direction. This can reduce a difference in ink remaining amount between the tanks corresponding to print heads.

A method of treating a contoured surface with surface treatment layer includes applying a surface preparation layer along the contoured surface and applying a basecoat layer on top of the surface preparation layer. The method further includes stabilizing the basecoat layer to prepare a basecoat surface along the basecoat layer for one or more subsequent layers of the surface treatment coating and jetting a decorative livery layer along the contoured surface using one or more ink jet print heads. The method further includes applying an adhesion promoter on top of the decorative livery layer and stabilizing the adhesion promoter layer to produce a desired bonding surface along the adhesion promoter layer. Additionally, the method includes applying a clear coat layer to cover the underlying decorative livery layer, the basecoat layer and the surface preparation layer.

Provided is an inkjet recording device control method including: a printing object detection step of detecting a printing object; a charge control signal transmission step of transmitting signals for controlling charges of a plurality of nozzles at a timing when the printing object is detected in the printing object detection step and signals are received from all of a plurality of processing units; and a printing step of controlling the plurality of nozzles and performing printing on the basis of the signals for controlling the charges that have been transmitted in the charge signal transmission step.

A printer (5) operable to print a message in strokes on a substrate (7) passing in a print direction (8) along a moving line (6), wherein the printer is operable (15) to receive an indication of an allowable increase in length in the print direction of a message due to an increase in length in the print direction of gaps between successive strokes printed by the printer, to receive (14) an indication (9) of a speed of movement in the print direction of a moving line, to determine from the indication of the speed of movement of the moving line whether an increase in length in the print direction of a message printed by the printer is greater than the allowable increase in length and, if so, to generate an alert,

An embodiment of this invention solves memory shortage that occurs in enlargement processing of an image because a web application holds data of an image or the like not as binary data but as character string data. In the embodiment, a processor in an information processing apparatus executes a program including a first program layer with an instruction set to be interpreted and executed by the processor and a second program layer with an instruction set interpreted in advance by a unit other than the processor in the following way. That is, the first program layer draws an image, and divides and enlarges the drawn image using a memory. Image data of each of a plurality of images obtained by the division and enlargement is output from the second program layer to an external device.
