A coloring device for coloring a dental prosthesis by an inkjet method, the dental prosthesis coloring device includes an inkjet head having a nozzle that ejects ink droplets; a holding unit that holds the prosthesis; a drive unit that moves the inkjet head or the holding unit in a predetermined direction in an XYZ orthogonal coordinate system; and a control unit that controls the inkjet head and the drive unit, wherein the control unit is configured to control the inkjet head and the drive unit based on predetermined coloring data and three-dimensional data of the prosthesis.

A glass container has an outer glass surface with an inkjet printed image provided on the surface. A cold-end coating (CEC) with a thickness between 0 to 20 nm is present between the outer glass surface and the inkjet printed image. Such glass container is preferably a one-way beverage bottle. A method of inkjet printing an image on a glass container comprises the steps of (a) manufacturing a glass container having a CEC layer; (b) removing at least part of the CEC layer to a level wherein the remaining CEC layer has a thickness of 0 to 20 nm; and (c) inkjet printing an image on the glass container.

A method is disclosed for reducing the scatter of UV light during a final curing operation in the three-dimensional printing on the surface of transparent and semi-transparent media. The method precisely controls the movement of media during a final cure step in the printing of an expressed inkjet image on the surface of transparent media. The method also controls a number of factors during final curing operation such as the lateral movement of media under a final cure lamp, the number of rotations that media undergoes during final curing, the timely modulation of UV lamp power during final curing, and the selection of UV emitter segments positioned away from a inkjet print head to reduce the amount of potential UV radiation from impinging upon one or more of the adjacent printing heads.

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 microparticles 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.

This disclosure describes systems, methods, and apparatus for decorating a can comprising a base, a curvilinear side surface extending in an upward direction from the base and comprising a neck and flanged portion, wherein the base and curvilinear side surface are formed using a metallic material, and at least one layer each of a first ink and a first overvarnish applied on at least a portion of the curvilinear side surface. The method further comprises surface treating the curvilinear side surface to increase a surface energy of the first overvarnish, applying one or more layers of an obscurant coating to the portion of the curvilinear side surface, wherein the portion may or may not include the neck and flanged portion, applying one or more layers of a second overvarnish and/or second ink to the portion of the curvilinear surface of the can, and curing the can.

A method according to the teachings of the present disclosure may include disposing a sheath around a conductor assembly, with an outer surface of the sheath defining spaced apart crowns and valleys. An outlet of at least one ink jet print head may be positioned adjacent the sheath at an angle of 60 degrees to 120 degrees with respect to a longitudinal axis of the sheath. The method may also include using at least one ink jet print head to print marking indicia on the sheath, the marking indicia indicating at least characteristic of the electrical cable assembly.

A method of template manufacturing for paper die-creasing and folding application is disclosed; first of all, an image file having die-creases is output to a UV inkjet printer first, and a template is disposed in the UV inkjet printer to allow the UV inkjet printer to print the image file on the template, thereby forming the image file having die-creases on the template; then the template with the image file having die-creases thereon is assembled onto a roller of a die-creasing machine to carry out a die-creasing process for paper materials.

A method of printing on a plurality objects comprises arranging a first plurality of objects on a board having a flat upper surface, the first plurality of objects arranged on the board in a first configuration, and adhering a plurality of rail members to the flat upper surface of the board, the plurality of rail members arranged around a perimeter of each of the first plurality of objects to define borders for each of the first plurality of objects in the first configuration. The method further comprises positioning the board on a printer, printing on the first plurality of objects with the printer, and removing each of the first plurality of objects from the board. The method further comprises subsequently printing a second plurality of objects on the board.

A three-dimensional object print apparatus performs a first step at which a liquid ejecting head ejects liquid onto a workpiece and simultaneously a moving mechanism changes a location of the liquid ejecting head relative to the workpiece along a first route and further performs a second step at which an energy emitting section irradiates the liquid on the workpiece with energy and simultaneously the moving mechanism changes the location of the liquid ejecting head relative to the workpiece along a second route. In this case, L1<L2 at the first step and L1>L2 at the second step, where L1 denotes a distance in a direction normal to a nozzle surface of the liquid ejecting head between the workpiece and the nozzle surface, and L2 denotes a distance in a direction normal to an emission surface of the energy emitting section between the workpiece and the emission surface.

An arrangement of a workpiece which is 3-dimensionally structured at least in partial surface regions, at least having a decoration applied above and/or below the structured workpiece surface, and at least one illumination source is described. The decoration comprises at least one coating material, wherein the amount of the coating material applied to the workpiece in a location-specific manner correlates with the height of the 3-dimensionally structured surface of the workpiece at this location, wherein the 3-dimensionally structured workpiece surface is at least partially translucent and the illumination source is arranged to couple light either laterally and/or at the rear and/or at the front into the workpiece surface. Furthermore, a method for coating 3-dimensionally surface-structured workpieces is presented.
