Hi-Res Inkjet works by making vertically placed ink chambers (nozzles) fire ink dots towards the material to be printed (substrate). The printhead with the nozzles is placed in a fixed position along the productionline while the substrate is being transported infront of it. The print is then generated by the sequence in which the ink nozzles are being fired. Because the nozzles are individually piezo-electrically controlled, printing variable data per print is possible.

Because the ink dots are fired onto the substrate without it making contact with the printhead, this is referred to as non-contact coding. The distance that the inkdots are able to cover towards the substrate is called their “throw distance”. In the case of Hi-Res Inkjet, these dots are only a few tens of Pico litres in size making a very high resolutions of 185 DPI possible at full coding speed. As the ink dots are fired straight from the nozzles, the maximum height of the print is determined by the height of the print head. The most common heights are 18 mm and 54 mm at possible coding speeds of up to 70 metres per minute.
