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. The printing system is configured to apply vacuum action through apertures or perforations defined through the perforated platen. In an embodiment, the print system is configured to mitigate deflection of ink drops, through the implementation of both a passive system, which reduces air flow in the region below the a print bar that includes one or more printheads, as well as an active system, which distributes the workpieces, e.g., substrates or boards, with respect to perforations in the transfer belt. In some embodiments, the perforated platen is comprised of a plurality of modular plates.
Embodiments of the invention provide a technique that effects spot gloss or gloss control and/or variations on one image without requiring clear inks. This is preferably accomplished by use of a multilayer printing process in which an image is first printed using a first set of color print heads and then cured, and in which the image is again printed using a second set of color print head, but where the image remains uncured for a predetermined interval to allow the ink drops applied to the media to spread and thus introduce a gloss effect.

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.

A media thickness detection system for inkjet printing applications monitors the thickness of media entering the printer to ensure correct printing performance by adjusting the position of the printheads on-the-fly to assure printing quality. Media that do have an acceptable printing thickness are passed through the printer without stopping operation of the printer transport and without being printed upon and are routed directly to a reject facility. Embodiments also prevent damage to the printer by immediately stopping operation of the printer when substrate thickness deviates significantly from an expected value due to variations in thickness that result from manufacturing tolerances or damage to the substrate.

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.

The systems and methods presented here completely separate a non-user pattern from the user jobs being printed. In fact, depending on the number of images in the job and the number of patterns provided by the manufacturer or press operator, the patterns may appear on different images of the job each time the job is printed. This is because the image marks are generated and processed according to the configuration of ROUS, independent of the user jobs being printed.

When a job does not exactly match the purpose of a printing profile but would benefit from some of the characteristics of a different printing profile, dynamically making the tradeoffs between the printing profiles is desirable. For example, a high-ink, large gamut profile might not be needed for a particular job, but an ink-saving profile would be excessively grainy. An intermediate profile would be recommended. Alternatively, the ink-saving profile can be adequate for everything except the skin tones in the print. Presented here are systems and methods to create a blended representation that could adopt the high-ink rules for a portion of the image, but ink-saving rules elsewhere. For example, the high-ink rules can be applied to the skin colors, but ink-saving rules can be applied in other parts of the image.

Embodiments of the invention provide a technique that effects spot gloss or gloss control and/or variations on one image without requiring clear inks. This is preferably accomplished by use of a multilayer printing process in which an image is first printed using a first set of color print heads and then cured, and in which the image is again printed using a second set of color print head, but where the image remains uncured for a predetermined interval to allow the ink drops applied to the media to spread and thus introduce a gloss effect.

Each EHD system includes a tensioned band for holding down an edge of a substrate as it passes through a printer assembly without impacting the print area. The tensioned band can be affixed between an entry tension assembly and an exit tension assembly disposed downstream of the entry tension assembly in the media feed direction. The tensioned band holds the substrate substantially flat against a transfer belt during printing by applying pressure to the surface of the substrate. The tensioned band generally contacts the surface of the substrate substantially proximate to an outer edge that is parallel to the media feed direction.

The present invention relates to a process for preparing a decorative fired substrate such as ceramic, glass, brick, metal or metal enamel. The process includes a step of digitally applying a primer ink composition comprising a metal or metalloid ion component dissolved in a liquid matrix on selective locations of the substrate. The primer ink composition can be applied before or after the application of a color ink. By applying a primer ink composition, the color of the substrate is improved after the substrate is fired, and the manufacture cost is reduced compared with current industrial decorative ceramic tile processes.

Elastic bending mechanism for bi-directional adjustment of print head position
Mechanisms for adjusting the position of one or more print heads at an extremely fine resolution (e.g., less than 10 μm) are described herein. The adjustment mechanisms include a differential screw and an indexing wheel through which the differential screw extends. One threaded segment of the differential screw is connected to a threaded feature of a flexible body that is coupled to the print head(s), while another threaded segment of the differential screw is connected to a threaded feature of a rigid body that is coupled to a printer assembly. As the indexing wheel and differential screw rotate, the space between the flexible body and the rigid body changes based on the difference between the pitches of the threaded segments. The adjustment mechanisms described herein utilize the accurate, consistent motion of the flexible body upon experiencing pressure to effect predictable changes in the position of the print head(s).

FABRIC PRINTING ON NESTED PATTERNS, AND ASSOCIATED PRINT SYSTEMS AND PRODUCTS THEREOF
Disclosed are methods that couple effective nesting of fabric, as part of a textile cutting process, in which designs and/or graphic elements are directly printed on the nested elements, instead of on the entire textile sheet. Embodiments of the invention can address issues of waste and redundant printing, such as by starting with a blank textile roll, and printing only in the geometry areas of the patterns. Embodiments of the invention can increase fabric yield, because there are no constraints between the pattern geometries and the textile sheet print.

Process for generating images with realistic modifications
A method for generating an output image with realistic individual text inserts via software loaded on a computer is provided. The method comprises the steps of providing a base image in a commercial graphical format with at least one position frame defined within the base image; the position frame defines an area within the base image where a text insert is insertable; providing software loaded on the computer which transforms a low resolution image into a high resolution image; defining a vector path within the position frame; arranging the text insert along the vector path; composing the text insert wherein the such step comprises the steps of selecting individual elements, sizing the individual elements as a function of the vector path, assembling the elements into letters, and assembling the letters along the vector path to compose the text insert; and entering text of the text insert via a user interface.
Individually controllable ultraviolet (UV) light-emitting diodes (LEDs) are used to cure ink and generate different effects. The UV LEDs only expose specified areas to generate the different effect and can create multiple effects on the same substrate by exposing different areas to varying amounts of time or by performing a curing stage and post-dosage curing stages. The different effects include generating a glossy surface, a matte surface, and sharper images.

UV dye sublimation decoration of complex-shaped objects
Various of the disclosed embodiments concern printing systems configured to deposit flexible dye sublimation inks onto flexible transfer materials. Together, the flexible ink and transfer material allow images to be transferred onto complex-shaped, i.e. non-planar, surfaces of a substrate. The flexible ink may be, for example, a thermoformable UV dye sublimation ink or a superflexible UV dye sublimation ink. In order to transfer an image onto the substrate, the transfer material is pressed onto the surface of the substrate. The substrate, transfer material, or both are heated to a temperature sufficient to cause the ink to sublimate. During the sublimation process, dye is able to permeate the substrate and form a transferred image. The flexible ink formulation may also include a soluble or solvent-sensitive component. In such embodiments, a solvent can be jetted onto the substrate and/or transfer material to remove residual ink.

These inspection results are tied back to a digital printer to take one or more of several possible actions. Actions include ensuring a particular number of acceptable prints are generated and sorted. Actions further include performing nozzle checks without pausing or interrupting production orders.
B41J 2/045 - Ink jet characterised by the jet generation process generating single droplets or particles on demand by pressure, e.g. electromechanical transducers
Various embodiments concern inkjet printing systems designed for multilayer imaging with a high-gloss clear ink layer. More specifically, the inkjet printing systems are designed so that clear, curable inks are provided additional time to level out before being cured. The settling process enables the inkjet printing systems to produce multilayer images having high gloss values. For example, a bracket could be attached to a curing assembly that prevents radiation from striking a certain portion of the substrate onto which clear ink has recently been deposited. As another example, an inactive array of light-emitting diodes may be disposed in line with the print head(s) responsible for depositing clear ink. Moreover, various embodiments also allow for true multilayer printing of a color coat and a high-gloss clear coat in a single step (e.g., by arranging print heads into rows within a printer carriage).

A transparent white ink composition is formulated to brighten, lighten and or dilute full-tone primary inkjet colors: cyan; magenta; yellow and black, eliminating the need for ‘light ink’ primary color inks. The transparent white ink is jetted concurrently with reduced amounts of full-tone inks in lighter tonal areas conventionally supported by ‘light ink’ primary inks. Printing ‘light ink’ primary colors using a transparent white ink composition may reduce the number of print channels needed to print all four primary colors and the four ‘light ink’ primary colors. Embodiments of the transparent white ink composition may be solvent- or water-based, drying by evaporation of the carrier fluid. Other embodiments may be radiation-curable ink compositions. An inkjet printer includes print carriage and print head assemblies configured for jetting a primary color ink and the transparent white ink in the same pass in correct proportions to achieve a desired effect.
