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: 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 imprinted upon 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.

Abstract: A dye discharge composition exhibiting extended shelf life and/or pot life and high suitability for inkjet printing on dyed substrates, is disclosed. The composition comprises a reducing agent such as, for example, a sulfur-based reducing agent, and a chelating agent, such as a sodium salt of a polyamino carboxylic acid chelating agent. Use of the dye discharge composition in combination with a translucent colored composition and an optional opaque underbase composition, for forming an image on a dyed substrate is also disclosed. Processes for inkjet printing of an image on a dyed surface using the dye discharge composition or an ink formulation containing same, and kits for use in such processes, are also disclosed.

Abstract: Novel processes for printing high quality, high resolution, multi-color images on darkly colored fibrous or porous materials or other ink absorbing materials, is disclosed. The processes are effected by digitally printing a layer of an opaque, lightly colored ink composition, followed by digitally printing the colored image thereon, and optionally further involve applying a wetting composition prior to and/or subsequent to these printings. Processes utilizing wetting compositions and/or liquid ink compositions which can interact therebetween so as to effect a chemical and/or physical change in one or more of these compositions are further disclosed.

Abstract: Disclosed are a process for inkjet printing color images on various substrates using a formaldehyde-free crosslinking agent in the ink composition, which is therefore devoid of formaldehyde emission and suitable for health-aware manufacturing practices, as well as objects having images and designs printed thereon which are devoid of formaldehyde and therefore suitable for use by infants.

Abstract: A digital printing machine including a rigid frame, a first linear motion X axis stage mounted on the frame, a printing table assembly movable on each linear X axis stage, a linear motion Y axis stage mounted on the frame perpendicular to the linear X axis stages, above the printing table assemblies, and an array of inkjet nozzles mounted on the linear Y axis stage for linear motion perpendicular to the X axis stage.

Abstract: A carousel and station-based printing system for textiles comprises one or more stations with a digital printing apparatus and optionally other stations with a stencil printing apparatus. The system allows for high speed printing of images having details of high resolution, rich colors, or variability, optionally also comprising a wetting apparatus operative to wet at least a part of the printed object prior to the digital printing.

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.
