An ink set includes a water-based coloring ink and a water-based coating liquid having an acting of aggregating the water-based coloring ink, wherein a dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coating liquid is smaller than a dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coloring ink, a difference between the dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coating liquid and the dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coloring ink is 5 mN/m or more and 20 mN/m or less, and the dynamic surface tension value at 25° C. at a surface life of 100 ms of the water-based coating liquid is within a range of 20 to 30 mN/m.

A printing device for building material articles, comprises a tank (2) for a printing material, solid or liquid, to be dispensed, an outlet mouth (3) suitable for dispensing the printing material onto a work surface, a conduit (5) extending along its own main direction (A) between the tank (2) and the outlet mouth (3), in which the conduit (5) comprises at least one deformable wall (6) movable between an operating position, in which it determines the creation of a restriction in the conduit (5) preventing the flow of the printing material towards the outlet mouth (3), and a rest position, in which it allows the flow of the printing material towards the outlet mouth (3).

A mineral ink for inkjet printing on a mineral substrate, includes a glass frit, an organic solvent, a dispersant, a surfactant and a glass fit including the following constituents in the weight limits defined below expressed as percentages by weight of the glass frit: 35 to 50% of SiO.sub.2, 15 to 25% of Al.sub.2O.sub.3, 1.5 to 4% of Li.sub.2O, 22 to 32% of B.sub.2O.sub.3, 0 to 2% of Na.sub.2O, 2 to 5% of K.sub.2O, 1 to 5% of CaO, 1 to 4% of ZrO.sub.2.

A system and method for printing patterns on a substrate, including a substrate; a powder; a sealing coating; and a UV curable paint; wherein the powder, the sealing coating and the UV curable paint are deposited onto the substrate and heated and cured. The method is designed to make the substrate have a faux appearance with lower costs than manufacturing the real substrate it was meant to look like.

A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and further comprising printing a printed pattern on at least a top surface of the engineered stone.

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.

The present invention concerns a surface covering element comprising: a mineral substrate layer, optionally coated with a suitable primer; a decor printed onto the substrate layer, forming a decor layer; anda transparent protection layer obtained from a curable polymer formulation. It further concerns a process for its manufacture comprising the following steps: a. providing a mineral substrate layer; b. optionally, applying a primer onto at least one surface of the mineral substrate layer; c. printing a decor onto the substrate layer; and d. coating the printed decor with a transparent protection layer obtained from a curable polymer formulation.

The present disclosure relates to a decorative panel made of flat glass for electronic household appliances, in particular, for large stationary household appliances. The decorative panel comprises a base body made of thermally tempered flat glass with an operational front and an operational back and has at least one digital print on the operational back.

The present invention relates to a printing method for transferring printing substance from an ink carrier to a substrate, in which the printing substance undergoes a change in volume and/or position with the aid of an energy-emitting device that emits energy during a process time in the form of electromagnetic waves wherein the printing substance comprises a high molecular weight binder. In addition, the present invention describes a printing substance for carrying out the method and the use thereof.
