Description
Photoluminescent Film Having Digital Images and Methods of Preparing and Using Same
Field of Invention This invention relates to images created on photoluminescent film.
Background of Invention
Photoluminescent films are known and are commercially used to - provide signage that warns, cautions, and provides other messages conveying safety information. Frequently, these films are combined with an adhesive to form a photoluminescent tape. Sometimes also characterized as "Glow-in-the-Dark", "luminous", or "luminescent", these films or tapes are based on materials that absorb photons and emit visible light.
Photoluminescent films and tapes can be found in commercial catalogs such as the Seton Identification Products Catalog (Seton Products,
Branford CT, page AE33, 1996); D&G Sign and Label Catalog WK (D&G Sign and Label, Northford, CT, page W37, (Summer 1996); and Bradv-Signmark Division Catalog s- 17 (W.H. Brady Co., Milwaukee, WI, p. 46, 1996). Typical messages include "Danger— High Voltage"; "Exit"; "Fire Alarm"; "Fire Extinguisher"; "Oxygen No Smoking"; and the like. Some of the messages include graphics and multiple colors such as the "Danger— High Voltage" sign with the "Danger" printed in photoluminescent white in a red oval within a black rectangle above "High Voltage" printed in black within a photoluminescent white rectangle. The messages are prepared using silk-screening or other analog printing techniques.
The art of electronic graphic systems has become quite advanced and very popular for using digital, computer-generated techniques to produce multiple color, precise images on a variety of substrates, including durable substrates suitable for long-term interior or exterior use. Minnesota Mining and Manufacturing Company of St. Paul, MN
(3M) has developed two different types of electronic graphic systems.
The Scotchprint™ Electronic Graphics Systems from 3M uses an electrostatic deposition of a latent image on a transfer medium, toning of that image on the medium, and transfer of the toned image from the transfer medium to a durable substrate such as Scotchcal™ branded vinyl, adhesive-backed film. The imaged film can then be applied to a variety of surfaces to display the image, including truck trailer sidewalls and walls, fascia and floors of buildings. U.S. Pat. Nos. 5,045,391 (Brandt et al.): 5,262,259 (Chou et al.); 5,106,710 (Wang et al.); and 5,114,520 (Wang et al.) disclose the electrostatic transfer process and materials used therewith. Media used to receive the latent image and media used to receive the transferred image are specially prepared to receive the electrostatic digital images.
The 3M Thermal Ink Jet Materials uses thermal inkjet deposition of pigmented, durable inks from commercially available thermal inkjet printers onto receptor media (either opaque or transparent) to generate a multiple color images. U.S. Pat. No. 5,342,688 (Kitchin et al.) and PCT Patent Publication WO 96/08377 media from 3M used in thermal inkjet image production. Media used for inkjet digital printing is specially prepared to receive the inkjet inks.
Photoluminescent film is commercially available from 3M as 3M™ Scotchcal™ Luminous Film Series 5700 that provides a luminosity that lasts up to six hours after photon excitation in the film ends. Basic lettering messages, such as "Exit" have been tested by 3M on such luminous film where the non-luminous lettering has been printed using silk-screening techniques or the non-luminous lettering has been electrocut using a cutter commercially available from Gerber Scientific Products and adhesively applied to the luminous film. The Luminous Film Series 5700 has a surface of photoluminescent material to generate the luminosity and previously has not been considered as a medium to receive either electrostatic toned images or inkjet inks, both of which have been generated using digital techniques.
Summary of Invention
One aspect of the present invention is the generation of digital images on a photoluminescent surface. An imaged film, comprises (a) a photoluminescent surface on the film, and (b) a digital image contacting the photoluminescent surface. Another aspect of the present invention is a method of making a digital image on a photoluminescent surface. A method of making a digital image on a photoluminescent surface, comprises the steps of (a) obtaining a digital image and a film having a photoluminescent surface, and (b) printing the digital image on the surface. Yet another aspect of the present invention is a method of using a digital image on a photoluminescent surface. A method of using a digital image on a film having a photoluminescent surface, comprises the steps of (a) illuminating the digital image and surface; and (b) ending illumination of the digital image and surface to reveal a photoluminescent image. A feature of the present invention is the unexpected discovery of the receptivity of a photoluminescent surface on Luminous Film Series 5700 from 3M to electrostatic transfer processes disclosed in U.S. Pat. Nos. 5,045,391 (Brandt et al.): 5,262,259 (Chou et al.); 5,106,710 (Wang et al.); 5,114,520 (Wang et al.); and 5,071,728 (Watts et al). Another feature of the present invention is the ability to generate luminosity in the image in differing and controlled degrees based on any method of digital printing that relies on the color of the substrate to create the final image. In other words, any image that relies on the "white" substrate to generate a lighter hue of color also results in a glow in the dark on that portion of the image based on the amount of "white" substrate showing through the image.
Another feature of the present invention is the ability to generate a different photoluminescent image from the illuminated image, such that a "new" message or picture "emerges" from the digitally printed image seen in natural or artificial light. Another feature of the present invention is the ability to generate an emphasized photoluminescent image from the illuminated image, such that a
message or picture "becomes more prominent" in an image after lighting of the image is diminished or "remains" in an darkened image after lighting of the image is removed.
An advantage of the present invention is the unexpected use of commercially available digital printing methods and commercially available films to generate new and exciting ways of displaying different images depending on the level of lumens reaching the surface of the image.
Another advantage of the present invention is the versatility of the digital imaging techniques combined with rapidly emerging computer imaging techniques wherein any image of any combination of colors from any source can be captured, manipulated, and printed using known digital imaging techniques and commercially available materials to produce unexpected beautiful, eerie, informative, or entertaining images that glow in the dark.
Other features and advantages become apparent in the discussion of embodiments of the invention and the following drawings.

Examples
An image from a popular movie and an image of a popular consumer product were generated in a Scotchprint Electronic Graphics System and printed on No. 8601 Electrostatic Paper using a Nippon Steel Corporation 9512
Electrostatic Paper. The toned images were transferred from the 8601 Electrostatic Paper to Series 5700 Scotchcal™ Luminous Film using an Orca III Laminator at a rate ranging from about 1.5 feet per minute (0.45 meters/min.) to 2.8 ft/min. (0.85m/min.) at a hot roll heated to 290°F (143 °C). A 3M No. 8626 overlaminate was applied to both imaged films.
The images were unexpectedly and remarkably precise approaching photographic quality and true in color to the original image, except for a slightly yellowish green tint in the normally white areas of the images
After illumination under fluorescent light, a view of the imaged films in the dark produced a glow of photoluminescent images with portions in one of the images of a helmet in dimmed photoluminescence and "light reflection points" of bright photoluminescence.
