Abstract: The invention relates to a support assembly (1) for an ink-jet printing device, comprising a support (3) with a guide track (2), which runs in the longitudinal direction of said support, for a moveable unit that travels along said guide track (2). A supporting element (4), which likewise extends in the longitudinal direction, is associated with the support (3) of the support assembly (1) and the ends (10, 11) of said support element (4) are supported on the support (3) against the effective gravitational direction. In addition, the support (3) and the supporting element (4) are tensioned with respect to one another along their longitudinal extension by means of at least one adjusting element (13).

Abstract: The invention relates to a method for producing a multicolored surface on a ceramic element or glass by means of the drop-like application of variously colored primary ceramic process color inks containing a carrier fluid onto at least one portion of a surface of the ceramic element or glass, wherein mixed colors are produced by printing on top of one another at least two primary process color inks, and the subsequent firing of the applied ink drops. At least one (photo)oligomerizable or (photo)polymerizable additive is added to the primary ceramic process color inks. Prior to printing over an ink drop with another ink drop the ink drop is hardened at least partly or its viscosity is increased.

Abstract: The invention relates to an adhesion-promoting additive for an ink for imprinting glass comprising at least one silane, and at least one reticulating agent based on an organic ester of o-silica.

Abstract: The invention describes an inkjet printer with a printing bed for displacing a print medium in a forward feed direction and a print head carriage disposed above the printing bed for displacing at least one print head unit in a transverse feed direction, a print head unit with at least one print head being provided for every colour to be printed, each print head having at least one nozzle row oriented in the forward feed direction of the print medium. The nozzles of the at least one nozzle row of the print head unit are disposed offset from one another by a nozzle distance D by reference to the forward feed direction. Another print head unit is provided, which has nozzles in at least one nozzle row disposed offset from one another by a second nozzle distance d by reference to the forward feed direction of the print medium, the ratio derived from the nozzle distance D and the second nozzle distance d being a rational number and greater than 1.

Abstract: An inkjet printer with a print head carriage is disposed above the printing bed for displacing a print head unit in a transverse feed direction, a print head unit with at least one print head being provided for every color to be printed and having at least one nozzle row oriented in the forward feed direction of the print medium. Another print head unit is provided for applying white ink, whereby the row length of the color print head unit and the row length of the other print head unit at least partially overlap with one another, and whereby of the nozzles of the nozzle row of the color print head unit, only those nozzles lying outside of the overlap region between the row length of the color print head unit and the row length of the other print head unit activated for applying white ink are activated.

Abstract: The invention relates to a conveyor unit constituting a separating and feed mechanism (33), in particular for sheet-shaped workpieces, in particular sheets (3) to be printed, with a lifting mechanism (2) for transporting the sheet (3) vertically and a conveyor track with conveyor means (51, 52) for transporting the sheet (3) horizontally. This being the case, the conveying means (51, 52) are displaceable in a guide system between an operating position for feeding the sheet (3) to a production unit (36), in particular a printing machine (37), and a non-operating position to enable the sheet (3) to be lifted unhindered from a sheet stack (39).

Abstract: The invention relates to a method and a device for coating at least one portion of a glass and/or ceramic substrate (2). In the latter output devices (5, 12, 22-25) are assigned to an application device (1) controlled by a control device (16). Said output devices (5, 12, 22-25) are assigned holding containers (18, 19) for holding a particle fluid (8, 26) and a pigment fluid (10, 27). The particle fluid (8, 26) and the pigment fluid (10, 27) are applied in a previously coordinated manner in terms of time and spatial distribution onto the substrate (2) to be coated.
