In a digital to garment printer having a rotary printing motion one or more T-shirt carriers are arranged on a fixed radius and rotate around a central column which houses one or more rotary tables. Each carrier is independent of the others but shares the same radius of rotation about the central column. All T-shirt carriers may share the same plane of rotation or be offset vertically and move to the printing plane with the up-down motion of the central column. On the same radius there are a series of fixed stations for printing as well as pretreatment, drying, and post treatment. The printing motion is achieved through the rotation of the T-shirt carrier that swipes under the print heads. The stepping motion can be achieved through the radial motion of the T-shirt carrier or the movement of the print head carrier.

Machine learning-implemented inkjet processing for generation of three-dimensional relief on tiles
A technique is described for the application of three-dimensional (3D) relief to a substrate such as a ceramic tile using digital inkjet technology. A computer system receives information defining a relief pattern for forming the 3D relief using a digital inkjet printer. From the information, a feature vector is extracted comprising one or more features describing the 3D relief. A machine learning model is used to generate control commands based on the feature vector. The machine learning model is trained to generate the control commands to configure the digital inkjet printer to apply binder ink to a first region of a surface of the substrate. The applied binder ink is configured to form a protective layer over the first region of the surface of the substrate. The digital inkjet printer is configured to apply solvent ink to the surface of the substrate.
A printing system having a vacuum transfer belt conveyor includes a fixed or movable perforated platen that supports workpieces, e.g., substrates, boards or other parts, to be printed.

In some embodiments, the perforated platen is comprised of a plurality of modular plates.
Techniques for more accurately and efficiently replicating the alignment of one or more printer components with respect to another printer component are described herein. Replication may be achieved by using a fixture and a connection media to create a near exact replica of features of the fixture, or to temporarily hold multiple printer components in position while a joining layer of the connection media hardens. More specifically, a connection media, such as epoxy, can be used to fill an intentionally-established gap between connecting bodies or components that are held in a predetermined position by the replication fixture. The replication fixture represents a mechanical mounting interface that influences the position of a print head (or an array of print heads) within a printer housing or printing mechanism. Joining printer components in such a manner enables a stable mechanical coupling to be formed that does not require post operations.

Disclosed herein is a technique that enables a carriage printer to reduce precision in a media conveyor by improving mobility of the carriage. The carriage includes a mobile jetplate that adjusts the position of the printheads within the carriage. The mobile jetplate includes multiple motors that enable shifts in an axis matching the axis of the media. Operating the motors of the jetplate at different locations or at different intensities causes the jetplate to skew and achieve mobility of multiple axes. A set of sensors monitor media skew and shifts of the mobile jetplate are able to compensate for that skew. An additional set of motors shift the carriage to compensate for deformation of the beam that the carriage shuttles along.

Disclosed are high stability ink delivery system systems and methods for their use, in which a secondary reservoir is placed upstream of a printhead. The secondary reservoir can be opened to the atmosphere through a valve, such as based on the reading of a pressure sensor placed at a point before the printhead. The purpose of this valve is to open the secondary reservoir to the atmosphere when the pressure sensor indicates that the secondary reservoir can be open while avoiding air aspiration, and closing it when this condition is not satisfied.
A linear rotary encoder includes a pair of rotational surfaces. A contact belt has a first end coupled to a first rotational surface in the pair and a second end coupled to a second rotational surface in the pair. The contact belt is driven to rotate around the pair of rotational surfaces by a driving force applied to media to move the media from the first end toward the second end. An encoding scale is coupled to an inner surface of the contact belt. A reader is positioned to read the encoding scale as the contact belt rotates around the pair of rotational surfaces. The reader generates an output signal indicating a position of the media based on reading of the encoding scale.

Printer vacuum conveyor with adjustable active area
A printing system includes a driving belt configured to drive media through the printing system relative to one or more print heads and a vacuum conveyor system. The vacuum conveyor system includes a vacuum chamber cover having a first surface and a second surface opposite the first surface, as well as a plurality of openings through the cover from the first surface to the second surface. A number of seals are disposed to match the location of openings. Each seal extends along the length of the vacuum chamber cover and is drivable to open or close a region with openings. A vacuum chamber below the second surface of the vacuum chamber cover is configured to apply a vacuum to the media through one or more of the openings that are open. The applied vacuum constrains the media on the driving belt by flattening it against the driving belt.

Ink jet printing on a non-absorbent substrate involves a wet primer having a primer viscosity. The wet primer is applied on the non-absorbent substrate. An ink jet ink having an ink jet viscosity lower than the primer viscosity is jetted over the wet primer while the primer is still wet. The wet primer and ink are simultaneously cured on the substrate.

Techniques for more accurately and efficiently replicating the alignment of one or more printer components with respect to another printer component are described herein. Replication may be achieved by using a fixture and a connection media to create a near exact replica of features of the fixture, or to temporarily hold multiple printer components in position while a joining layer of the connection media hardens. More specifically, a connection media, such as epoxy, can be used to fill an intentionally-established gap between connecting bodies or components that are held in a predetermined position by the replication fixture. The replication fixture represents a mechanical mounting interface that influences the position of a print head (or an array of print heads) within a printer housing or printing mechanism. Joining printer components in such a manner enables a stable mechanical coupling to be formed that does not require post operations.
The disclosed embodiments include a method to compensate for defective printer nozzles. The method can include detecting a defective printer nozzle and initiating a print job including image data of the defective printer nozzle for a pixel location of an image. The image is to be printed in accordance with a print mask that maps printer nozzles to pixel locations of the image. The method can include modifying the image to print the image data in a neighboring pixel location relative to the pixel location of the image and printing the modified image.
