A liquid ejecting device performing printing by ejecting liquid onto a medium in a printing region, the liquid ejecting device including an ejecting unit including a first ejecting unit ejecting the liquid onto the medium, and a second ejecting unit ejecting a reaction liquid containing a coagulant for coagulating a component in the liquid, a transport unit configured to transport the medium, a jam detector configured to detect a jam of the medium, and a control unit configured to control the ejecting unit, and the transport unit, wherein when the jam is detected in the jam detector, the control unit causes the transportation of the medium by the transport unit to stop, and causes the liquid, the reaction liquid, or the liquid and the reaction liquid to be ejected in the printing region from the first ejecting unit, and the second ejecting unit.

Disclosed is an image forming apparatus including an image forming unit that ejects droplets from an image forming apparatus, and forms an image on a surface of a printing medium, a pre-processing unit that applies a pre-processing liquid to the surface of the printing medium before the image is formed by the image forming unit, and a post-processing unit that applies a post-processing liquid different from the pre-processing liquid to the surface of the printing medium after the image is formed by the image forming unit. The pre-processing unit applies an amount of the pre-processing liquid which is determined based on a type of the printing medium and the post-processing unit applies an amount of the post-processing liquid which is determined based on the type of the printing medium.

Embodiments of the invention relate to a method of indirect printing with an aqueous ink formulation applied to the surface of the intermediate transfer member. Related apparatus, systems and treatment formulations are disclosed herein.

The inventions relates to a method for producing a decorative workpiece with a structured surface comprising the following steps: (B) applying a first liquid lacquer having a coarse structuring over the entire surface, wherein a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm; (E) applying a second liquid, at least partially transparent lacquer for producing a fine structuring in some regions.

A method comprising: digital printing a heat curable aqueous composition onto a substrate, wherein the composition comprises: (a) at least one water soluble synthetic alkali metal silicate; and (b)(i) at least one pigment or (b)(ii) at least one additive selected from aluminum oxide, ceramic microspheres, recycled ground glass, or calcium carbonate; and wherein the substrate comprises a material selected from glass, ceramic, textile, polymeric, metal, wood, or a combination thereof.

To provide an ink jet recording method capable of suppressing generation of image streaks and recording a high-quality image, when using a recording apparatus equipped with a line head. Provided is an ink jet recording method which records an image on a recording medium by using an ink jet recording apparatus equipped with a line head. In this method, the line head has a plurality of recording element substrates each having a nozzle array made up of a plurality of nozzles which eject an aqueous ink. The recording element substrates are arranged in the predetermined direction. An average temperature Te (° C.) of an aqueous ink ejected from terminal-portion nozzles constituting the terminal portion of the nozzle array and an average temperature Tc (° C.) of an aqueous ink ejected from center-portion nozzles constituting the center portion of the nozzle array satisfy the following relationship: Te>Tc.

The present disclosure relates particularly but not exclusive to a method for printing in a multipass print mode using a first printhead (PT1) and a second printhead (PT2), the method including printing in a first pass a first image in a first area of a print medium using a first set (ST21) of nozzles (N5-N24) from the first printhead (PT1), printing in a second pass a coating layer over the first image using a second set (ST22) of nozzles (P4-P22) from the second printhead (PT2), and printing in a third pass a second image over the coating layer using a third set (ST23) of nozzles (N1-20) from the first printhead (PT1).

A printing apparatus according to the present invention includes a plurality of ejection heads for ejecting liquid and a plurality of mist collection units configured to collect mist generated by the ejection heads that are disposed along a medium conveyance direction.
