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.

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. In an example embodiment, the introduced technique includes application of binder ink to a portion of the surface of a substrate using a digital inkjet process. This binder ink forms a barrier layer which protects the portion of the surface of the substrate. Next, a brushing process is applied to remove unprotected portions of the substrate, thereby forming the 3D relief in the substrate.

Inkjet process for three-dimensional relief on tiles

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.

Method and composition for ink jet printing on a nonabsorbent substrate

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.

An energy curable foam inhibition ink composition comprises an oligomer component consisting of 5-15% by weight of the ink composition, a photoinitiator component consisting of 5-15% by weight of ink composition, a monofunctional monomer component consisting of 20-40% by weight of ink composition, a difunctional monomer component consisting of 10-20% by weight of the ink composition, and an inhibitor additive consisting of 5-20% of the ink composition.

Energy curable foam inhibition ink

A radiation-curable ink composition for application to glass, ceramic, or metal by an inkjet printer. The ink composition can be applied to a glass, ceramic, or metal substrate to decorate, protect, etc. the substrate. In some embodiments, the ink composition includes a glass frits component, a chromophore component, and a UV-curable component. The glass frits component facilitates the fusing of the ink component with a glass, ceramic, or metal substrate to which the ink composition is applied. The chromophore component is the primary colorant of the ink composition. The UV-curable component facilitates activation of polymerization upon exposure to ultra-violet (UV) radiation, which causes the ink composition to cure and fix/pin to the underlying substrate. After the ink composition is applied to a substrate and cured by exposure to UV radiation, the substrate is heated to a temperature that causes the ink composition to fuse with the substrate.

Radiation-curable inkjet ink for application to glass, ceramic, or metal

Various of the disclosed embodiments concern removable ultraviolet (UV) curable dye sublimation ink to be used in various printing systems and printing methods. In some embodiments, the ink includes a dye component, a UV curable component, and a soluble or solvent-sensitive component. In order to print an image on a substrate, the ink is heated to a temperature sufficient to cause sublimation of at least the dye component. During the sublimation process, the dye is able to permeate the substrate and form a printed image. After the transfer process has been completed, a solvent can be jetted onto the substrate that causes the soluble component to dissolve. The washing process ensures that any residual ink remaining on the surface of the substrate is substantially removed.

Removable ultraviolet curable dye sublimation inks

A system and methods for printing and curing ink deposited on a substrate using a first light source and a second light source. In various embodiments, the first light source emits one or more wavelengths of electromagnetic radiation subtype C (UVC), and the second light source emits one or more wavelengths of electromagnetic radiation subtype A (UVA), subtype B (UVB), subtype V (UVV), or a combination thereof. The substrate is configured such that any ink deposited on the substrate by a printer head is predominantly exposed to the first light source prior to the second light source.
