Direct-to-object printing.

Inkjet printing straight onto a finished item such as a bottle, a phone case, a tile or a wooden panel, rather than onto film that is applied to the item afterwards. Machines built for it cure UV-LED ink as the lamp passes over the fresh drop, commonly carry a primer channel for surfaces the ink will not bond to on its own, and are bounded by a maximum object height and by how close the head can ride over a curved face. Registration is the difference from flat work. A jig holds the object, so every new shape needs its own fixture and its own height setting before the first good print, and a misfire scraps the blank instead of a sheet of media, which on customer-supplied goods is the expensive half of the job.
