Described is an assembly of a guiding structure and a print head carriage, the print head carriage comprising a base carriage controllably movable relative to the guiding structure along a first horizontal axis, the print head carriage comprising a sub-carriage controllably movable relative to the base carriage along a second horizontal axis. The print head carriage comprises an intermediate carriage controllably movable relative to the base carriage along a vertical axis, the sub-carriage mounted on the intermediate carriage for moving together with the intermediate carriage relative to the base carriage, the sub-carriage controllably movable relative to the intermediate carriage along the second horizontal axis.

A printing system has a print head shuttle containing a print head mounted on a print guide rail, a support shuttle containing support electronics for the print head mounted on a support guide rail adjacent and parallel to the print guide rail, and at least one electronic signal-carrying cable connected between the support electronics and the print head.

A method for printing on the surface of an object uses a print head generating ink drops to print at least a first swath and subsequently a second swath of ink onto the surface in such a way that the swaths are mutually adjacent and overlap in a strip. The first and second swaths are printed as solid areas and the swaths are XY stitched in the strip. In the strip, at least one of the two swaths is additionally stitched by using a function of an ink amount profile in a Y direction. High-quality or even highest-quality printed products can therefore be produced, in particular avoiding defects that are visible to the human eye in a region of overlap or a strip between swaths that are printed next to one another.

A liquid ejecting apparatus includes a head that can eject liquid, a carriage that holds the head and can move in an intersecting direction, a support portion that can support a medium from a side opposite the side on which the head is located, a frame portion that is provided upstream of the carriage in the transport direction, the carriage being attached to the frame portion, a cover portion that covers the carriage, a first adjustment part that is attached to the frame portion, and a second adjustment part that is attached to a positioning portion. A difference between a first adjustment distance and a second adjustment distance is smaller than a difference between a first distance and a second distance.

The present teachings disclose various embodiments of a printing system for printing a substrate, in which the printing system can be housed in a gas enclosure, where the environment within the enclosure can be maintained as a controlled printing environment. A controlled environment of the present teachings can include control of the type of gas environment within the gas enclosure, the size and level particulate matter within the enclosure, control of the temperature within the enclosure and control of lighting. Various embodiments of a printing system of the present teachings can include a Y-axis motion system and a Z-axis moving plate that are configured to substantially decrease excess thermal load within the enclosure by, for example, eliminating or substantially minimizing the use of conventional electric motors.

An imaging apparatus includes a print engine having a printhead that generates ink drops, and a printhead carrier that carries the printhead in a first direction and in a second direction opposite the first direction. A controller determines an initial print direction based on ink drop information obtained by printing patches in the first direction and in the second direction, wherein the ink drop information includes a respective chromatic value of each of the patches. The controller is operatively coupled to the print engine to print an image based on the initial print direction.

In a case in which a dot of a first raster line to be discharged by a first defective nozzle and a dot of a second raster line to be discharged by a second defective nozzle are determined to be adjacent to each other in a sub-scanning direction when a transport unit performs movement by a predetermined first distance, a printing device performs first control of executing either control of changing a distance of the movement performed by the transport unit immediately before the first defective nozzle forms the first raster line by an integer multiple of a nozzle pitch from the first distance, or control of changing a distance of the movement performed by the transport unit immediately before the second defective nozzle forms the second raster line by an integer multiple of the nozzle pitch from the first distance.

A method for printing at least one section of a flat or preferably curved surface of an object includes using a relative movement between an inkjet head and the object to move the inkjet head along a first path and print a first track in the process and to move the inkjet head along a second path and print a second track in the process. A first track edge of the first track and a second track edge of the second track meet at a point and enclose an angle between about 1 and about 179 at the point. The method permits the curved surface to be printed without perceptible track connections.
