Abstract: An inkset and a process for direct inkjet printing color images on dyed synthetic fabrics is provided herewith, based on forming an image on the fabric in the form of a well-adhered crosslinked film, using an acid-immobilized ink composition, while avoiding dye migration from the fabric to the image in the process of curing the film, using a low-temperature curing crosslinking agent and curing the image at a temperature lower than 120±5° C.

Abstract: A fixation/transfer device for control of dye waste in a dye sublimation process. The device comprises a textile inlet, a textile outlet, a heat press or calender, an endless belt for driving the textile from the textile inlet to the textile outlet through the heat press, the heat press being held at a temperature sufficient to cause sublimation of the printing dye, and a cleaning station for cleaning the endless belt, the cleaning station being located downstream of the textile outlet and upstream of the textile outlet. The feed belt may be heated at the cleaning station so that sublimation may assist cleaning.

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: A novel process for printing high quality, high resolution, multi-color images on fibrous or porous materials or other ink absorbing materials, or on materials having high surface tension with a liquid ink, and especially over garments, is disclosed. The process is effected by applying a wetting composition, prior to, concomitant with and/or subsequent to applying an ink composition and formation of the images. Pre-printing and printing systems for executing the above process are further disclosed.

Abstract: Methods relating to the printing of materials using hybrid ink formulations are generally described.

Abstract: A pallet for holding garments during printing comprises a base and a frame pivotally attached to the base, to hold a garment in a space between the base and the frame, the frame being locked onto the base over the garment to define the space. The pallet comprises a primary locking mechanism to lock the frame into a first position defining a relatively small space for a thin garment and a secondary locking mechanism for locking the frame into a second position defining a relatively large space for thicker garments, thereby providing a single pallet that can accommodate garments of a larger range of thicknesses, for example t-shirts and sweaters or hoodies.

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: Apparatus for picking a garment having a front and a back and placing the garment over a pallet such that the front and the back of the garment are on the front and the back sides respectively of the pallet. The apparatus comprises a picking arm to approach the garment and then withdraw towards the pallet; and one or more adherence locations on the picking arm, the adherence location being smaller than the first side, the adherence location for contacting the garment using sticky material and causing adherence of the garment via the sticky material at the contact location, thereby causing the picking arm to pull the front of the garment over the front of the pallet, the back of the garment sliding under the first side onto the back of the pallet.

Abstract: A method of recycling ink used in non-printing nozzle dispensing operations in an ink jet printer, comprises collecting the ink from the non-printing operation in a collection tray, draining the ink from the collection tray into a closed cell, draining the ink from the closed cell, filtering the ink draining from the closed cell, and adding the ink back to a main ink supply after filtering, the main ink supply containing fresh ink. To maintain the quality of the ink supply the proportion of recycled to fresh ink may be limited to a maximum.

Abstract: Novel inkjet ink compositions for forming an image in a form of an elastic film attached to a surface of a stretchable and/or flexible substrate and processes utilizing same for inkjet printing color images on various substrates such as colored and absorptive or impregnable stretchable materials, which are characterized by heightened efficiency in process time, ink and energy consumption, as well as products having durable, wash-fast and abrasion-fast images printed thereon by the process, are disclosed. The novel ink compositions comprise a first part, which contains a property-adjusting agent and a carrier, and a second part which contains an emulsified property-sensitive proto-elastomeric film-forming agent, a colorant and a carrier, such that the second part congeals upon contact with the property-adjusting agent. The second part is digitally applied to the substrate less than 1 second following the application of the first part to the substrate.

Abstract: A hold-down pallet for a textile printer, the pallet comprising a central board and flaps, the flaps moving between an open position to allow placing of a garment and a closed position to hold a garment firmly on the board for printing, the pallet travelling between a garment setting position and a printing area and comprising an engagement mechanism which engages the pallet as it enters the garment setting position. Engagement opens the flaps so that the flaps are in the open position in the garment setting area, the pallet disengaging to close the flaps as it heads for the printing area.

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.
