## Background
This application is a continuation-in-part of U.S. Ser. No. 11/533,447, filed Sep. 20, 2006, which claims priority from U.S. Provisional Patent Application Ser. No. 60/718,709, filed Sep. 20, 2005. The disclosures of these applications are incorporated herein by reference.


BACKGROUND
Labels are commonly used to secure printed indicia to packages to indicate shipping or other information. In the instance of a shipping use, a customer is often provided with a label that is separate from the package to be shipped. The separate label will be enclosed within a package shipped to the customer containing a purchased item. The separate label is generally preprinted for use if the customer wants to return the item. The customer is generally responsible for properly preparing the label for adhesion to the package by removing a liner. The customer must then properly position it and affix the label. Difficulties during use may arise if the separate label is lost, becomes damaged, or is improperly positioned on the package.
For the foregoing reasons, it is desired to provide a shipping return label that reduces the frequency of times item return labels are lost, damaged, or improperly positioned.

Computer 390 can include a personal computer, a computer terminal, a personal digital assistant (PDA) and/or other types of devices as may occur to one of ordinary skill in the relevant art after being presented with the disclosure herein. In one embodiment, computer 390 is a personal computer. In at least one embodiment, a datafile of variable indicia is stored on computer 390, which computer is electronically interconnected with variable printer 332b. Such electronic interconnection may be accomplished by hardwiring, radio frequency communication, or such other forms of electronic interconnection as may occur to one of ordinary skill in the relevant art after being presented with the disclosure herein. As second label material 372 passes under or through variable printer 332b, computer 390 transmits data from the datafile to variable printer 332b, which data is output by variable printer 332b as variable indicia on second label material 372. In at least one embodiment of the present disclosure, variable printer 332b comprise computers, software, and printer systems provided by Scitex, Kodak, or other such providers.
In at least one embodiment of system for automated production of a plurality of multi-part labels according to the present disclosure, multi-part label stock including all indicia printed thereon may be finished by one or more optional finishing operations. For example, in the embodiment of system 300 shown in FIG. 6, following second variable printer 332b multi-part label stock 378, including all indicia printed thereon, is fed through a first die station 338. In this embodiment of system 300, at first die station 338, an undercut die cuts through both the liner component and the label material component of first label material 370, but not through the second label material 372, thereby creating a corner peel tab for one or more of the discrete multi-part labels that are to be formed from the continuous roll or web of multi-part label stock 378. In at least one embodiment of system 300, at first die station 338, an undercut die cuts only through the liner component of first label material 370, and not through the label material component of first label material 370 or through second label material 372, thereby creating a corner peel tab for one or more of the discrete multi-part labels that are to be formed from the continuous roll or web of multi-part label stock 378.
In another example of a finishing operation, in the embodiment of system 300 shown in FIG. 6, following first die station 338, multi-part label stock 378 is fed through a second die station 338, where a die cuts through second label material 372 and the label material component of first label material 370, but not through the liner component of first label material 370, thereby creating discrete multi-part labels that remain affixed to the liner component of first label material 370. It should be noted that it also is possible to die cut the boundaries of discrete multi-part labels before die cutting the corner peel tabs.
An additional die station 338 is shown in the embodiment of system 300 of FIG. 6. Such additional die station 338 optionally may be adapted for specialty die cutting and punching operations. Other embodiments of system 300 may adapted to include one or more additional optional die stations to meet the die cutting and punching needs of a particular multi-part label design.
In the embodiment of system 300 shown in FIG. 6, following die stations 338, multi-part label stock 378 is fed through an optional waste removal station 340. Waste removal station 340 is operable to remove all or substantially all of the portions of second label material 372 and the label material component of first label material 370 that are outside the boundaries of discrete multi-part labels affixed to the liner component of first label material 370, while leaving the discrete multi-part labels affixed to the liner component of first label material 370.
In the embodiment of system 300 shown in FIG. 6, following waste removal station 340, multi-part label stock 378 is fed through an optional slitter station 342. Slitter stations 342 may be used where multi-part label stock 378 is configured so that a plurality of streams of discrete multi-part labels are arranged across the width of multi-part label stock 378. Multi-part label stock 378, including the discrete multi-part labels affixed thereto, may be slit into individual streams of discrete multi-part labels at slitter station 342.
In the embodiment of system 300 shown in FIG. 6, following slitter station 342, multi-part label stock 378 may be fed through optional sheeter station 344 and optional fan folder 346. Optionally, in at least one embodiment of a system for automated production of multi-part labels according to the present disclosure, multi-part label stock 378 may finished by cutting perforations between discrete multi-part labels at sheeter station 344, which labels are then fan folded at the perforations into flat packs by fan folder 346. Optionally, in at least one embodiment of a system according to the present disclosure for automated production of multi-part labels, multi-part label stock 378 may finished by shearing, at sheeter 344, multi-part label stock 378 into discrete sheets, including the discrete multi-part labels affixed thereto.
Also shown in FIG. 6 is optional rewinder 348. In at least one embodiment of a system according to the present disclosure for automated production of multi-part labels, multi-part label stock 378 may finished by winding multi-part label stock 378, including the discrete multi-part labels affixed thereto, on a roll by rewinder 348. Where used, rewinder 348 is used in lieu of sheeter station 344 and fan folder 346, according to at least one embodiment of the present disclosure.
System 300 of FIG. 6 represents merely an exemplary embodiment of a system according to the present disclosure for automated production of multi-part labels. For example, although two variable printers are shown in the embodiment of system 300 shown in FIG. 6, the present disclosure is not limited to systems comprising two variable printers. Other embodiments of systems according to the present disclosure may comprise more than or less than two variable printers.
Also, for example, in systems according to the present disclosure for automated production of multi-part labels, the one or more print stations, one or more variable print stations, and one or more laminating processes may be arranged so that zero colors, one color, or a plurality of colors may be printed on the first label material and/or on the second label material, and/or on any other layer of label material that may be part of a multi-part label. Similarly, the one or more print stations, one or more variable print stations, and one or more laminating processes may be arranged so that a release coat may be applied to all, a portion, or none of the first label material and/or on the second label material, and/or on any other layer of label material that may be part of a multi-part label. Similarly, the one or more print stations, one or more variable print stations, and one or more laminating processes may be arranged so that variable indicia may be printed on the first label material and/or on the second label material, and/or on any other layer of label material that may be part of a multi-part label.
Also, for example, many embodiments of systems, methods, and labels disclosed herein discuss a plurality of multi-part labels comprising at least one liner-backed layer. Multi-part labels that do not comprise at least one liner-backed layer, and systems and methods related to the same, are within the scope of the present disclosure. For example, in lieu of a liner-backed layer, a multi-part label according to at least one embodiment of the present disclosure may comprise a layer backed with a dry gum adhesive or another form of adhesive. Each such embodiment of a multi-part label is within the scope of the present disclosure.
