     FIELD OF THE INVENTION 
     The present invention relates to methods for printing from a digital-based image directly onto products made from paper, polyethylene, or other materials. 
     BACKGROUND OF THE INVENTION 
     Printed and unprinted flexible and semi-rigid packaging materials are commonly used for packing retail, industrial, and commercial products into plastic bags, paper bags, sacks, pouches, wrappers, and the like. Printed and unprinted flexible and semi-rigid packaging materials are also commonly used for covering or storing retail, industrial, and commercial products. Desired features of packaging materials include printability and different levels of opacity. Packaging materials can either be printed or imprinted. Printed packaging materials can use a single color or multiple colors. Graphics printed on the packaging materials can include company logos, association logos, advertising and text. Graphics can be used to communicate promotional or educational messages. 
     Offset printing is a commonly used printing technique for printing images, graphics and/or text on printed surfaces such as paper bags. Offset printing occurs when an inked area is transferred from a metal or rubber plate to a rubber cylinder (commonly called a “blanket”), and then transferred to a printing surface such as paper. The process is called “offset” because the inked image is offset or transferred to something else first (e.g. the rubber blanket) before being transferred directly to the printed surface. 
     Offset commercial printing presses and inkjet desktop printers both use some combination of the following ink colors: cyan (“C”), magenta (“M”), yellow (“Y”), and black (“K”). Offset printing is also typically referred to as 4-color printing or 4-color process lithography. 
     With offset printing, separate plates are created for each color. The plates are then put onto a press. The press pulls in the ink from ink reservoirs and puts the ink onto the plate. The press then applies pressure to the plate and the ink imprints the image from the plate onto a rubber blanket. The image is then pressed onto the paper off the blanket to make a print. Often, the ink also permeates the substrate being printed on, resulting in “bleed through” and an unacceptable end product. Offset printing occurs very rapidly and is best suited for long runs over a long period of time and for producing many items with the same printed image. 
     Digital printing refers to methods of printing from a digital-based image onto a surface or substrate, without requiring the need for separate, analog plates. Unlike conventional ink used in offset printing, the ink or toner used in digital printing does not permeate the substrate, but forms a thin layer on the surface. Digital printing allows for on demand printing, short turnaround time, and simple modifications of the image used for each impression (variable image printing). 
     Digital printing can use computers, tablets, or mobile devices to stream data to inkjet printers for printing. Inkjet print heads inside the printer fire or spray fine dots of ink at a surface to create an image, images, or text. One type of inkjet prim head fires ink towards a printing surface by heating the ink so it explodes on the surface in bubbles. Another type of inkjet print head uses piezoelectricity, whereby tiny electric currents cause miniature crystals to jiggle back and forth, firing dots of ink at a surface. 
     Digital printing can also use computers, tablets, or mobile devices to stream data to laser printers for printing. Electronic circuits in the printer make a laser beam move back and forth across a drum inside the printer, causing static electricity to attract a powdered ink or toner to the printed surface. A fuser then bonds the toner to the surface, resulting in a printed image, images or text on the surface. 
     U.S. Pat. No. 5,795,280 relates to an apparatus for facilitating the registration of printed matter during the manufacture of bags on fixed-size bag formation equipment, from a continuous web of a substantially non-stretchable material. Printed matter, printed upon the continuous web at regularly-spaced intervals, includes a plurality of periodically spaced reference markers.

     U.S. patent publication no, 20030173716 relates to a colored polyolefin film printed by digital printing. The colored polyolefin film is formed by blending a coloring agent with a polyolefin, and forming a film from the blend by an extrusion process. Digital signals are supplied to a printer adapted to respond to such signals to print the colored film. Indicia may be placed on the surface of the colored film by electrostatic printing, thermal transfer printing or ink jet printing, especially with UV curable ink jet ink.

       FIG. 3  shows substrate  60  being unwound from a roll  70  via an unwinder  80  and fed to a bag machine  200  for forming the substrate  60  into a bag which is then fed into a digital printing system  10  via an integrated drive mechanism (not pictured) to deliver individual bags. Printed bags  40  are received individually on a table  120  for packing. 
       FIG. 4  shows substrate  60  being unwound from a roll  70  via an unwinder  80  and fed to a bag machine  200  for funning the substrate  60  into a bag which is then fed into a digital printing system  10  via an integrated drive mechanism (not pictured) to deliver individual bags to the digital printing system  10  and an integrated drive mechanism (not pictured) to receive and stack printed bags  40  in a reservoir  50 . 
       FIG. 5  shows substrate  60  being unwound from a roll  70  via an unwinder  80  and fed to a digital printing system  10  for deposition and fusing of ink or toner onto the substrate  60 . Substrate  60  with printing is then fed to a bag machine  200  via an integrated device mechanism (not pictured) to deliver substrate sheet to the bag machine. Printed bags from the bag machine  200  are received on a table  120  for packing. 
       FIG. 6  shows a digital printing system  100  for inkjet printing that has an integrated feed system for printing paper bags. Bag  110  is stacked in Bag Stacker  115  and fed under alignment guides  120  onto a conveyor belt  130 . Bag  110  passes under alignment guides  140  before moving underneath digital printing unit  150 . Inkjet print heads (not shown) obtain ink from ink bottle (not shown) in digital printing unit to spray ink on bag surface to form image, images or text (not shown). Bag  110  moves underneath bag drying system  160 , before passing under alignment guides  140  on its way to bag stacker  170  for printed bags. Bag  110  continues to bag stacker  180 . 
       FIG. 7  shows inkjet printer  200  that has a print head  205  integrated with a print cartridge  210  positioned on sliding rod  220 . Stepper motor  250  advances paper sheet  240  from upper paper tray  230  through the inkjet printer  200 . Ribbon cable  270  carries printing instructions to the print cartridge  210 . Drive belt  260  guides print cartridge  210  as it moves across sliding rod  220 . Print cartridge  210  fires ink droplets across sheet  240  as it passes underneath print cartridge  210 . Printed paper sheet  245  ends up in bottom paper tray  280 . 
       FIG. 8  shows thermal print head  300  with ink chamber  310 . Resistor  320  causes a reaction that heats ink  340 , creating pressure that forces ink through nozzle  330  in the form of ink droplets  350 . Ink droplets get sprayed onto a printing surface or substrate  360  to create a printed image, images or text. 
       FIG. 9  shows non-thermal Piezoelectric print head  400  with a single jetting array and ink chamber  410 . Piezoelectric transducer  420  creates an electric charge that causes a thin layer of film (not shown) or crystal (not shown) to vibrate, creating pressure that forces ink  440  through nozzle  430  in the form of ink droplets  450 . The electrical current can be switched on an off very rapidly, allowing for greater control over the ink droplet formation and print density. Ink droplets  450  get sprayed onto a printing surface, or substrate  460  to create a printed image, images or text. 
       FIG. 10  shows non-thermal Piezoelectric print head  500  with multiple jetting arrays and ink chambers  410 . Piezoelectric transducers  420  create electric charges that cause a thin layer of film (not shown) or crystal (not shown) to vibrate, creating pressure that forces ink  440  through nozzles  430  in the form of ink droplets  450 . The electrical current can be switched on an off very rapidly, allowing for greater control over the ink droplet formation and print density. Ink droplets  450  get sprayed onto a printing surface or substrate  460  to create a printed image, images or text. 
       FIG. 11  shows the interior of a digital printing unit  600  with door  630  in the open position to make contents of digital printing unit visible.
