Definitions

  • the present invention relates generally to printing on articles of manufacture, and more particularly to a system and method for printing on multiple different types of articles of manufacture by the same conveyor printing system.
  • Performance improvements in computing, networking and communications has led to enormous advances in the number and types of capabilities that one can achieve using a networked device.
  • websites such as www.vistaprint.com allow a user of a networked device to select and customize template designs for printed and electronic products, and then to order and purchase quantities of such product(s).
  • the ability to customize designs for printed products becomes simpler for the end customer, the demand for customized printed designs on different types of products has increased.
  • consumers desire not only printed paper documents such as business cards, postcards, brochures, posters, flyers, etc., but also many other types of items such as shirts, hats and other garments, promotional items such as rulers, USB drives, calculators, toys, tape measures, etc., and other 2- and 3-dimensional items.
  • manufacturers of printed articles of manufacture typically imprint the same design on a long run of the same type of article of manufacture. This is due in part to the fact that mass production has traditionally been the realm of non-customized unpersonalized products, and further in part due to the high setup time for each print run. In general, in the past, higher efficiencies in terms of time and cost were achieved by printing the same design on large quantities of the same type of article of manufacture.
  • Mass customization poses problems to the traditional model for achieving high efficiencies in printing. For any given type of article of manufacture, there may be as many different unique designs to print as there are quantity of the particular type of article of manufacture. The problem is compounded when one adds into this mix any number of different types of articles of manufacture.
  • Embodiments include systems and methods for a conveyance printing system which prints any number of unique print designs on any number of different types of articles of manufacture in a continuous flow.
  • Embodiments of the invention may further be configured to allow multiple different types of articles of manufacture to be interspersed in a print manufacturing flow in any order and without regard to which type(s) of articles of manufacture are precedingly or succeedingly printed in the flow.
  • a manufacturing tray for processing of different types of articles of manufacture is configured with a tray base configured to interface with a transport system for transport through a processing system, an interchangeable tray inlay supported by said tray base and arranged to hold an article of manufacture loadable onto the tray inlay, and a tray identifier associated with processing information corresponding to the tray and to the article of manufacture, the processing information being indicative of a process to be performed by the processing system.
  • a printing system is configured for processing different types of articles of manufacture.
  • the printing system includes a conveyor system which receives and conveys one or more articles of manufacture from an entry port to an exit port of the printing system, an identifier reader which reads an identifier associated with the one or more articles of manufacture identifying a type of article of manufacture to be printed, a printer configured to receive print-ready content and to print the print-ready content on the received articles of manufacture, at least one of a pre- and/or post-print-processing treatment unit, and one or more controllers configured to selectively turn on or turn off one or more of the at least one pre- and/or post-print-processing treatment unit based on a determined type of article of manufacture to be printed as identified from the read identifier.
  • a manufacturing tray is configured for multi-function processing of different types of articles of manufacture.
  • the tray includes a tray base configured to interface with a conveyance system for transport through a multi-function processing system, a tray frame connecting to the tray base and configured to support each, individually at any one time, a plurality of different interchangeable tray inlays for holding different types of articles of manufacture, one of said plurality of interchangeable tray inlays supported by in said tray frame, and a tray identifier affixed to the tray, the tray identifier programmable to associate processing information with said tray and with a plurality of articles of manufacture loaded in said tray inlay, the processing information indicating to a processing system which processes the tray how to process the tray.
  • a printing system includes height-adjustment functionality for adjusting the distance between the target print surfaces and the print head nozzles.
  • This embodiment includes a printer comprising one or more print heads configured with a plurality of print nozzles positioned at a predetermined height, an engagement mechanism for holding a print tray during printing of one or more articles of manufacture held on the tray, a tray height adjustment mechanism responsive to a height adjustment signal to adjust the height of the engagement mechanism, a sensor which detects a parameter from which a relative distance between the print nozzles and one or more target print areas of the one or more articles of manufacture will be when printed by the print nozzles, and a controller responsive to the detected parameter to generate the height adjustment signal so as to cause the tray height adjustment mechanism to adjust the engagement mechanism to hold the print tray at a height such that the target print area of the one or more articles of manufacture will be within a distance of the print nozzles when the target print area is printed by the print nozzles.
  • Embodiments of the invention in general, support a new printing paradigm through methods and systems which alone or together allow any number of unique individual print content to be printed on any number of different types of articles of manufacture without interrupting the print manufacturing flow or causing downtime of the printing system(s).
  • One or more embodiments of the invention may further be configured to allow multiple different types of articles of manufacture to be interspersed in a print manufacturing flow in any order and without regard to which type(s) of articles of manufacture are precedingly or succeedingly printed in the flow.
  • One or more embodiments of the invention may further be configured to allow insertion of high-priority print jobs into the queue of a currently running print manufacturing flow without interrupting the flow or requiring any downtime of the printing system(s).
  • FIGS. 1A and 1B show an exemplary embodiment of a novel continuous-flow conveyance printing system 100 with capability to print on multiple different types of articles of manufacture using the same printer, and to print potentially different image content on every article of manufacture, without requiring the printing system to stop or be taken offline between jobs or between printing of different types of articles of manufacture.

If the ordered quantity of printed articles associated with an individual customer order is greater than one, then additional instances of the individual print-ready file 703 may be placed in additional cells of the associated gang template 1000 to cause the ordered quantity of the item to be printed.
  • the filled gang file 704 is sent to the conveyance printing system 740, where a tray of the type associated with the particular gang file 704 is loaded with corresponding articles of manufacture.
  • the loaded tray is conveyed to the printing system 150, where the gang file is printed as a single print job onto the articles of manufacture loaded on the tray 200.
  • the tray with printed articles (see FIG. 14D ) is then conveyed to an unloading station 140, wherein the printed articles are removed from the tray and sorted into individual orders by a human or a computerized sorting system.
  • the sorted orders may then be packaged for shipping by a packaging system.
  • each gang cell 1001 can contain a different print ready file containing different corresponding content.
  • Each individual print-ready file 703 may correspond to the same and/or different customer order.
  • embodiments of the tray inlay shown herein depict tray inlays configured to hold multiple instances of a single type article of manufacture, alternative tray inlays may be configured to hold articles of manufacture of multiple different types.
  • a tray inlay could hold one each of articles of manufacture types 99a, 99b, 99c and 99d.
  • the corresponding gang file would then include a cell for containing an individual article print file 703 for each type of article of manufacture 99a, 99b, 99c and 99d.
  • the conveyance printing system offers multiple advantages to the printing industry.
  • Features include, but are not limited to:
  • control functions utilized in the systems and methods described and illustrated herein may be implemented in software, firmware or hardware, or any suitable combination thereof.
