Abstract

Provided herein is an inkjet dye-sublimation ink composition that is formulated to interact with an immobilizing composition such that the ink composition coagulates on the surface of an absorptive substrate, thereby substantially limiting soaking of the ink composition into the substrate. Also provided are a printing process and a printing machine, wherein the ink composition is directly printed on the substrate concomitantly with the immobilizing composition, and thereafter undergo heat-pressing to afford a dye-sublimation transfer of the dye to the substrate, thereby forming an image which is characterized by sharp and well defined edges of the dyed areas.

Abstract

A method of printing a garment, particularly for use in sport and outdoor activities, to retain moisture wicking or heat management properties of an underlying fabric. The method comprises mapping active body regions onto a print file for the garment. Thus the print file defines standard print areas and modified print areas where the modified printing areas correspond to the active body regions. Printing onto the garment over the standard print areas uses a standard ink density, but printing onto the garment at the active areas uses a second lower ink density which preserves, or at least does less harm to, wicking and venting properties of the underlying fabric.

Abstract

Provided herein is a method for digitally printing an image on a fabric in the form of a film on the surface of the fabric, such that the film is characterized by improved properties over the entire image. The method is implemented by compiling in a test run a look-up table for at least one functional composition that confers a desired property to the image, and using the look-up table for printing any given image using just the optimal amount of the functional composition and only on portions of the image that require improvement.

Abstract

Apparatus and method for pre-treatment of synthetic fabrics, for example brushed polyester fabric, prior to printing to prevent fibrillation effects of the fabric on the print quality. The apparatus comprises a printing pre-treatment location where fabric is treated prior to printing and a heat source applying heat to a predefined printing area on the fabric at the printing pre-treatment location. The heat applied is sufficient to fuse outwardly extending fibers of the fabric back into the fabric using thermoplastic deformation, thereby to produce a treated printing area for printing. The apparatus may be online with a printer or may be offline and the heat treatment may optionally be combined with spraying.

Abstract

A garment feeder for feeding a garment for printing, comprises a loading position for a pallet and robotic grippers movable across the loading position to grip a garment from a first side of the loading position and pull the garment in a garment pull direction to a second side of the loading position to load the garment onto the pallet in the loading position. The garment being loaded slips across the loading position on the first side of the pallet perpendicular to the garment pull direction, and one or more sensors detect widthwise edges of the garment, now being pulled onto the pallet by the grippers. The positions of the edges can be used to determine if the garment is being pulled symmetrically onto the pallet. If not then the garment is adjusted to achieve correct positioning for printing.

Abstract

A system for networked printing of images onto textiles where the entity placing an order for printing has no control over the machines carrying out printing, comprises an electronic network and textile printing machines, belonging to different providers, attached to the network. Each of the printing machines has a corresponding printing quality profile of parameters that indicate abilities of the printer to reproduce an image on a textile. An input enables a user to place an order for textile printing of an image and select or define a required printing quality profile. The parameters of the image itself may demand certain printing quality levels. The textile printing order is sent for printing to a textile printing machine on the network that is selected for a printing quality profile which best matches the profile required. Other parameters such as cost, delivery time may also be considered.

Abstract

A textile printing system for digital printing of colored images onto typically colored fabrics, digitally using print nozzles or other digital means, the nozzles printing print pixels onto the fabrics. The system comprises a print file defining pixel colors for the individual printing pixels; and a deletion unit which deletes print pixels from the print file wherever a respective pixel color is within a threshold distance of the fabric color. The textile printer then prints the print pixels onto the fabric to form a colored image without printing any of the deleted pixels.

Abstract

Provided are compositions and processes formulated and practiced to reduce the friction-coefficient of the printed area and also of the non-printed areas around the image, wherein the compositions are formulated for use by wet-on-wet techniques in-line of the pre-curing printing process, without pretreating the fabric for softness and smoothness prior to the printing process. The compositions comprise at least 15% by weight of a friction-coefficient reduction agent and having a pH lower than 6.5 so as to effect upon contact immobilization of an ink composition that is being digitally applied on the substrate.

Abstract

A modular textile printing apparatus is made up of multiple modules which are combined together. Each module has one rail for bearing a printing functional unit such as a print head. A second rail perpendicular to the first rail faces the first rail, and carries a printing tray or platen holding items to be printed. The tray moves along the rail. A third rail parallel to said second rail and facing away from the printing functional unit, is also for carrying the tray. The modules are connected together and the apparatus provides a starting point for loading and unloading the trays. The second rails are aligned with each other to form a continuous printing feed along the modules and the third rails are aligned to provide a return path after printing to the starting point for reloading.

Abstract

Apparatus and method for digital printing comprises placing a medium to be printed on a print table and feeding towards a print head. A finite length of the medium approaching the print head is measured for variations in thickness towards the print head. Then, the height of the print head is adjusted to maintain a predetermined printing distance. Subsequently, if the extent reaches or exceeds the printing distance then it is assumed that wrinkles are present and printing is paused for readjustment of the medium, which may be a textile and more particularly a garment.

Abstract

A wrinkle detector for detecting creases or wrinkles to protect a print head of a fabric printer from occlusion by protruding fabric. The wrinkle detector comprises a mounting located in advance of a print head relative to fabric approaching to be printed, the mounting comprising one or more deflectable elements extending into a predetermined clearance zone between the printing head and the fabric, wherein deflection of the elements is used as an indicator of fabric protruding into the clearance zone. The detector may be used to halt or modify printing, in particular ink jet printing of the fabrics so that occlusion does not block the printing nozzles.

Abstract

Method and apparatus for digital printing of textiles with application of immobilization compound on the textile prior to printing. The method comprises, finding failed printing nozzles; carrying out immobilization of the textile without using at least some of the nozzles neighboring a failed printing nozzle; and printing the textile. The immobilization generally prevents the printing ink from running, so leaving out immobilization around the failed nozzle allows ink to seep into the unprinted gap. The immobilization however also stabilizes the ink, so one embodiment keeps some of the neighboring nozzles on during the immobilization.

Abstract

Compositions for and methods of digitally printing an ink image onto a woven textile material are provided. A base application is applied to the surface of a woven textile material, especially one comprising synthetic resin fibers prior to application of an ink image layer. The base application comprises an acrylic latex material that is formulated to be printed on with a digital ink while still wet, thereby eliminating the need for an intermediate drying cycle in between base application deposit and printing of the ink image.
