  • Patent number: 6817689
    Abstract: The system and method of the present invention forms an item specific pattern on a plain or holographic metallized film or hot stamp foil, including an embossed substrate with or without holograms. An ink jet printhead includes a plurality of ink jet channels and respective ink jets that receive one of etchant or etchant-resistant mask material for ejecting etchant or etchant-resistant mask material through the respective ink jets onto a metallized surface of the metallized film or hot stamp foil. A controller individually and digitally controls the ejection of etchant or etchant-resistant mask material in a programmed manner for ink jet printing on the metallized surface a unique pattern of etchant or etchant-resistant mask. Etchant etches the metallized surface into an item specific pattern by the ink jet printed etchant or subsequently applied etchant that exposes the metallized surface devoid of the etchant-resistant mask.

  • Patent number: 6786564
    Abstract: An inkjet printer for recording dot patterns corresponding to image contents is disclosed. The printer comprises an inkjet head (51) for performing recording by moving in a main scanning direction of a recording medium and injecting ink particles, drive waveform generating sections (24, 25) for generating drive waveforms for injecting said ink particles, and a head drive section (50) for selecting said drive waveforms and driving said inkjet head (51) in accordance with print data. The drive waveform generating sections (24, 25) generate drive waveforms for injecting said ink particles having different ink speeds within a unit cycle, in cycles each corresponding to one of the parts obtained by dividing the unit cycle by an integer. Thereby, by varying the speed of the ink particles injected in one cycle of the drive waveforms, the landing position of each dot in the cycle is controlled and hence the dot pattern in one cycle is varied.
