Definitions

  • the present invention relates to the protection of printed media, and, more particularly, to transparent, printed-sheet protection sleeves for printed transparencies.
  • ink-jet printers to form images such as alphanumeric characters and graphics on absorbent substrates, such as paper, is well-known.
  • non-ink receptive substrates such as polyester films, commonly known as Mylar
  • non-ink receptive substrates do not readily absorb the aqueous-based inks commonly employed in ink-jet printing, with the result that dots of ink are slow to dry and do not spread laterally on the non-ink receptive substrate.
  • non-ink receptive substrates is used to describe those substrates comprising materials which drops of ink deposited thereon do not readily penetrate.
  • U.S. Patent 4,914,451 also assigned to the same assignee as the present application, discloses a non-ink receptive substrate provided with an ink-receptive coating. This patent further discloses use of vapor permeable and water absorbent sleeve protectors, such as acetate, for allowing drying of the transparency during storage in the sleeve protector.
  • vapor permeable sleeve protectors described in the foregoing two patents allow the image to dry properly, but do not prevent long term image degradation from excessive moisture, specifically, atmospheric moisture (high humidity).
  • non-vapor permeable sleeve protectors such as polyvinyl chloride (PVC), polypropylene, and polyester (polyethylene terephthalate PET)
  • PVC polyvinyl chloride
  • polypropylene polypropylene
  • polyester polyethylene terephthalate PET
  • printed transparencies, or imaged films provided with an ink-receptive coating and printed upon by ink-jet printing, are provided with means to allow proper drying of the print while preventing long term image quality degradation of the printed transparency.
  • a vapor permeable sheet is first placed in contact with the imaged (inked side) ink-jet film. The vapor permeable sheet and the imaged ink-jet film are then inserted into a non-vapor permeable sleeve protector.
  • the present invention allows for immediate use of the imaged film in a non-vapor permeable sheet protector, such as polyvinyl chloride (PVC), polypropylene, and polyester (polyethylene terephthalate - PET).
  • a non-vapor permeable sheet protector such as polyvinyl chloride (PVC), polypropylene, and polyester (polyethylene terephthalate - PET).
  • PVC polyvinyl chloride
  • polypropylene polypropylene
  • polyester polyethylene terephthalate - PET
  • the imaged film may be archived substantially indefinitely without significant degradation of the image quality.
  • the imaged film is protected against image degradation caused by excessive moisture, including atmospheric moisture (high humidity).
  • the present invention promotes image development at dry atmospheric conditions (low humidity) and allows non-vapor permeable sleeve protector independence.
  • the present invention adds no significant haze (less than about 1%) or opacity to the projected image and allows the imaged film to dry properly.
  • the vapor permeable material described in U.S. Patent Number 4,914,451 is combined with any non-vapor permeable sleeve protector, whether sealed or unsealed on any or all of its sides.
  • the vapor permeable material allows the image to dry properly while the non-vapor permeable sleeve protector prevents image degradation from excessive moisture, including atmospheric moisture (high humidity).
  • the transparency preferably employed is that disclosed in U.S. Patent 4,914,451, because of the advantages that the ink-receptive coating provides.
  • Any of the known vapor permeable materials may be used in the practice of the invention, including those disclosed in U.S. Patents 4,810,544 and 4,914,451, such as a cellulose acetate, e.g., cellulose diacetate and cellulose triacetate.
  • Any of the known non-vapor permeable sleeve protectors may also be utilized in the practice of the invention, including polyvinyl chloride (PVC), polypropylene, and polyester (polyethylene terephthalate - PET).
  • FIG. 1 depicts the imaged ink-jet film 10 , having an image 10i thereon, contacted by the vapor permeable sheet 12 .
  • the assembly 14 is then inserted into the non-vapor permeable sleeve protector 16 .
  • the non-vapor permeable sleeve protector 16 is provided with two unsealed edges 16u , a folded edge 16f , and an open edge 16o . Alternatively, one or both of the unsealed edges 16u may be sealed. The assembly 14 is inserted into the open edge 16o . While the non-vapor permeable sleeve protector 16 is shown with three holes along the edge denoted 16u , it will be appreciated that the invention is not limited to the particular construction of the sleeve protector.
  • FIG. 2 provides plots of bleed between adjacent colors as a function of time for each of the foregoing combinations.
  • combination (a) is represented by Point 18
  • combination (b) is represented by Curve 20
  • combination (c) is represented by Curve 22
  • combination (d) is represented by Curve 24 .
  • the imaged films were imaged at 23°C/50% relative humidity and then stored in the above-indicated manner at 30°C/80% relative humidity.
  • Bleed in each instance was measured by printing a preselected number of dot rows of blue ink (cyan + magenta) between a pre-selected number of dot rows of red ink (magenta + yellow), with the borders of the blue and red colors just touching.
  • the blue ink swath had an initial width W1.
  • FIG. 2 indicates that the maximum bleed allowed for crisp, clear transparencies is 200 ⁇ m (Curve 26 ). Combinations (a), (b), and (c) each exceed this value. In direct contrast, combination (d), which is the combination of imaged film contacted by the vapor permeable sheet and inserted in the non-vapor permeable sleeve protector evidences bleed of less than 200 ⁇ m after accelerated exposure of 5 days at 30°C/80% RH.
  • the combination of the vapor permeable sheet material with the non-vapor permeable sleeve protector in accordance with the present invention takes advantage of the drying characteristics of the vapor permeable material and the sealing characteristics of the non-vapor permeable sleeve protector. This prevents significant long term image quality degradation of the imaged film.
  • non-vapor permeable sleeve protector for storing printed transparencies.
  • the non-vapor permeable sleeve protector could alternatively be provided with one or both of its inner surfaces coated with a vapor permeable coating.
  • the image stabilization system of the present invention is expected to find commercial use in protecting transparencies printed by ink-jet printing.
