A transparent print medium in roll form for recording image elements, comprising an elongated sheet of transparent material comprising opposed first and second surfaces and first and second opposed lateral edges, said first surface an image surface for recording thereon image elements, and having removably affixed to said second surface of said sheet a first reflective layer portion at a first lateral edge of the medium, a second reflective layer portion at a second lateral edge of the medium, and a third reflective layer portion intermediate the lateral edges, and a roll core, said elongated sheet rolled about said core with said lateral sheet edges at opposed ends of said roll core, and wherein said first reflective layer portion is defined by a first reflective strip of reflective layer material, and said second reflective layer portion is defined by a second reflective strip of reflective layer material.
- 17. A transparent print medium for recording image elements, comprising a sheet of transparent material comprising opposed first and second surfaces and first and second opposed lateral edges, said first surface an image surface for recording thereon image elements, and having removably affixed to said second surface of said sheet a first opaque reflective layer portion at a first lateral edge of the medium and a second opaque reflective layer portion at a second lateral edge of the medium, and wherein said first reflective layer portion is defined by a first reflective strip of reflective layer material, and said second reflective layer portion is defined by a second reflective strip of reflective layer material.
- 18. The print medium of claim 17 wherein said second strip has a width determined by a media sensor spacing distance from said second lateral edge.
- 19. The print medium of claim 17 wherein said reflective layer portions are characterized by an opacity characteristic value in excess of thirty percent opacity.
- 20. The print medium of claim 17 wherein said transparent medium is a layer of transparent polyethylene terephthalate, and said reflective layer portions are defined by one or more layers of polyethylene terephthalate filled with barium sulfate to provide a desired opacity.
- 21. The print medium of claim 17 wherein said sheet medium is rolled into a roll for dispensing print medium therefrom.
- 22. The print medium of claim 17 wherein said sheet of transparent material and said first and second reflective layer portions all have similar thermal coefficients of expansion.
- 23. The print medium of claim 17 wherein the print medium is for use in an ink-jet printer employing water-based ink to record said image elements, and wherein said first surface of said transparent sheet has applied thereto a hydrophilic coating to accept said water-based ink.
- 24. The print medium of claim 17 wherein said opaque reflective layer portions comprise aluminum.
- 25. The print medium of claim 17 wherein said opaque reflective layer portions each have white surfaces.
- 26. A transparent print medium in roll form for recording image elements, comprising an elongated sheet of transparent material comprising opposed first and second surfaces and first and second opposed lateral edges, said first surface an image surface for recording thereon image elements, and having removably affixed to said second surface of said sheet a first reflective opaque layer portion at a first lateral edge of the medium, and a second reflective opaque layer portion at a second lateral edge of the medium, wherein said first and second layer portions are separate and distinct reflective layer portions, and a roll core, said elongated sheet rolled about said core with said lateral sheet edges at opposed ends of said roll core.
- 27. A transparent print medium for recording image elements, comprising a sheet of transparent material comprising first and second surfaces and first and second opposed lateral edges, said first surface an image surface for recording thereon image elements, and having removably affixed to said second surface of said sheet a first opaque reflective layer portion at a first lateral edge of the medium, a second opaque reflective layer portion at a second lateral edge of the medium, and a third opaque reflective layer portion intermediate the lateral edges, and wherein said first, second and third reflective layer portions are respectively defined by first, second and third strip layers of a reflective material.
