A method for controlling drop collisions in a drop on demand printing apparatus, comprising discharging a first drop (101) from a first dispenser (111) to move along a first path (103) and discharging a second drop (102) from a second dispenser (112) to move along a second path (104) that crosses with the first path such that the drops are expected to collide and form a combined drop (105), characterized by: measuring the collision of the drops (101, 102); examining whether the collision was effected as expected; if the collision was not effected as expected, altering the parameters of dispensing of the drops (101, 102) from the dispensers (111, 112).

The invention relates to a printing device (10) for printing a surface (12), in particular the surface (12) of a workpiece (11) made at least partly of wood, a wood material, synthetic material, composite material or the like, comprising an ink supply device (17) which has at least two ink containers (21), each holding a printing ink (19), and an ink feed system (24) by means of which the printing inks (19) can be supplied to at least one print head (18), in order to carry out a printing process with at least one of the printing inks (19), wherein a flushing device (32) is provided, by means of which at least the ink feed system (24) and/or the at least one print head (18) can be flushed with a flushing liquid (33) for a printing ink change, and to a method for changing printing inks (19) in a printing device (10).

A method for manufacturing a colored sheet for coloring an object by adhesion to the object includes, a coloring step of applying by spraying, a first coating fluid containing first microp articles for coloring to a thin film of a print receiver body which has a sheet-shaped support body and the thin film, the thin film being peelably held on the sheet-shaped support body to serve as a base material of an adhesive sheet which is to be adhered to the object, and a restricting step of applying by spraying, before the coloring step, a second coating fluid for restricting the first microparticles from penetrating the thin film to a location where the first coating fluid is to be applied.

A 3D printer includes an ejector device comprising a substrate and a plurality of ejector conduits on the substrate, the ejector conduits being arranged in an array. Each ejector conduit includes: a first end positioned to accept a print material, a second end comprising an ejector nozzle, the ejector nozzle comprising a first electrode and a second electrode, and a passageway for allowing the print material to flow from the first end to the second end, at least one surface of the first electrode being exposed in the passageway and at least one surface of the second electrode being exposed in the passageway. A current pulse generating system is in electrical connection with the first electrode and the second electrode of the plurality of ejector conduits. A magnetic field source is sufficiently proximate the second end of the plurality of ejector conduits so as to generate a flux region disposed within the ejector nozzle of the plurality of ejector conduits during operation of the 3D printer. The 3D printer further comprises a positioning system for controlling the relative position of the ejector device with respect to a print substrate in a manner that would allow the print substrate to receive print material jettable from the ejector nozzle of the plurality of ejector conduits during operation of the 3D printer.

The embodiments herein discloses a system for dyeing fabrics on-demand, comprising a flatbed mechanism for loading a substrate for dyeing; an ink feeder mechanism, consisting of at least Cyan, Magenta, Yellow and Black (C, M, Y, K) colors and a color combiner mechanism or color mixer to combine the inks and create a composite ink; at least two nozzle heads to deposit the composite ink on both sides of a substrate; an operator console; and a reset mechanism. The nozzle is configured to move across the entire width of a substrate from one side to the other, while the substrate rolls to aid dyeing. The nozzle dyes a single color at any given time.

A recording method for using a line-type recording apparatus to scan a recording medium with a plurality of line heads once for recording, the line heads having a width greater than or equal to the recording width of the recording medium, the method including a treatment liquid deposition step of depositing a treatment liquid containing a coagulant on the recording medium, and an ink deposition step of ejecting a coloring ink composition from the line heads to deposit the coloring ink composition on the recording medium, wherein in the ink deposition step an identical coloring ink composition is ejected from a first line head placed on the upstream side in the transport direction perpendicular to the width direction of the recording medium and from a second line head placed on the downstream side in the transport direction.

A pretreatment liquid for inkjet recording contains a photobase generator that produces an organic amine compound through light exposure. An inkjet recording apparatus forms an image on an image formation area of a recording medium. The inkjet recording apparatus includes a pretreatment section, a light exposure section, and a recording head. The pretreatment section ejects the pretreatment liquid for inkjet recording toward the image formation area of the recording medium. The light exposure section performs light exposure on the image formation area of the recording medium to which the pretreatment liquid for inkjet recording has been ejected. The recording head ejects an ink toward the image formation area of the recording medium subjected to the light exposure to form the image.

The present invention provides an ink jet recording method capable of recording an image having good abrasion resistance by using an aqueous ink and a reaction liquid. In the ink jet recording method, the aqueous ink containing a resin particle and the reaction liquid containing a reactant for aggregating the component in the aqueous ink are ejected from a recording head of the ink jet system and applied onto a recording medium. The reaction liquid contains a compound represented by the general formula (1) (n in the formula represents an integer of 0 to 3). At least one of the aqueous ink and the reaction liquid contains a surfactant having an HLB value of ≤ 15.
