According to one embodiment, a tablet printing apparatus includes: a conveyer configured to convey a tablet along a line; an applicator head including a plurality of nozzles arranged in a direction crossing the conveyance direction of the tablet conveyed by the conveyer, configured to perform printing on the tablet by ejecting a liquid from the nozzles; and a controller configured to control the ejection of the liquid from the nozzles of the applicator head. The length of an array of the nozzles in a direction perpendicular to the conveyance direction is equal to or longer than the length of the tablet in the direction perpendicular to the conveyance direction. The controller is further configured to control switching of a nozzle used for printing on the tablet among the nozzles by a plurality of sections determined in advance.

The invention relates to a machine and method for single-pass digital printing on glass (1).

The machine comprises: a support structure (2) for securing the sheet of glass (1); and a printing bridge (3) which, during printing, can move along the longitudinal X axis of the support structure (2), said bridge supporting digital printing means (33) with print bars (100, 100, 100) comprising successive printing heads (10, 10, 10), as well as supporting a scanner (32) for capturing data relating to the positions of defects (X, Y).

A head unit includes heads arranged in a body. Each head includes a nozzle row arranged along a first direction. The heads are arranged along a second direction intersecting with the first direction. Two or more heads that include a nozzle row corresponding to a first color, are provided in each of a first region and a second region. A color corresponding to the nozzle row at an nth position from a first side is the same as a color corresponding to the nozzle row at an nth position from a second side, n being a positive integer, the first side being one side of the body in the second direction and the second side being another side of the body in the second direction.
