Abstract
A process of transferring a copy of a color picture, or other article, to a surface of an entity or sheet, by copying the color picture on a carrier sheet of paper or plastic with a color copier machine forming a toner image of the article. The toner image is rested on the surface of an entity to receive the picture. Heat and pressure are then applied to the carrier sheet thereby remelting the toner copy in contact with the surface of the article or sheet thereby transferring the copy to the entity and the carrier sheet is removed.
Description
. ~ 21 12512 I~AGE TRANSFER METHOD
BACKGROYND OF 'IIT~T~ INVENTION
There is a current need for ~ new method of transferring color copies of pictures on various articles of manufacture 5 that have a smooth exposed surface that are cheap, simple, and suitable for single images or low volume production.
The advent of electrophotographic copying, commonly referred to as x~royL~I~hy or plain paper copying, has provcd to be a highly successful proces8 for reproduction of images 10 on to paper with the inherent advantages of speed and reliability. In a conventional process, an electrostatic image of an object is formed on a recording member such as a plate or drum. The recording member may comprise a layer of photoconductive material, such as selenium, or a 15 conductive metal layer. The latent electrostatic image which is formed on the photoconductive material is developed into a visible image by application of toner powder or liquid and the image is transferred to a sheet of paper and affixed thereon by fusing, eg., by application of heat and 20 ~, ~sDuLe to form a permanent print. Full color images may be obtained by sequentially forming electrostatic color separation images on the recording member and using magenta, cyan, yellow and black toners in turn.
More recent developments in plain paper copiers include 25 the ability to electronically store and image and output the image in sections at a pr~ t~rm;ned level of magnification.
Thus, a relatively large image may be output as a series of A4 or A3 sized sections ("tiled"), each of which bears a portion of the f inal image . When the tiles are placed in 30 edge-to-edge abutment (after trimming any overlaps), the complete image is displayed.
STTMMARY OF TT~T~' INVENTION
The copying machine must be one of the types that use thermoplastic or meltable toner to form melted toner images 35 to the carrier sheet where it is remelted in contact with an entity . Such dry toner r-~h i n~ are manuf actured by the Canon Company, the Kodak Company and the Xerox Company.

21 ~2S12 Copy machines that use ink to form the images on a carrier sheet are not suitable for applicant's process since most inks cannot be remelted.
The carrier sheet is a sheet of heat resistant material 5 that will not be damaged at the temperatures that are needed to reheat the toner used in the machine. Any suitable sheet material, transparent or opaque can be used for the carrier sheet so long as it will not be damaged by remelting the toner .
The reheating means can be a platen type with a means to apply pressure and heat to the carrier sheet, or it could be of a drum, or belt type machine, that applies pLe:s~uLe to the work.
Entities to which the image is transferred can be any sheet of plastic or paper article having either a smooth, flat, or curved surface suitable to receive the transferred image. The present invention provides a simple efficient method of reproducing an image on an article of manufacture such as color pictures or plastic clips for holding papers together, or other articles having a relatively flat, smooth surface or on any suitable sheet material to receive the remelted image.
The method according to the invention comprises the following:
a. Providing a carrier 6heet capable of withstanding exposure to temperatures of at least equal to the remelting temperature of toner to be used.
b. Applying the image of the article to the carrier by the passage of the carrier sheet through the copying apparatus so that the toner image is melted onto the carrier sheet .
c. Resting the carrier sheet on the article with the toner image resting on the entity.
d. Applying heat and pressure to the carrier sheet whereby the toner image is remelted and transferred from the carrier sheet to the entity and the carrier sheet is removed .

It is an ob~ ect of the invention to provide an improved copying method.
It is another object of the present invention to provide a transfer method that i5 simple, ec~n~ ic~l and ef~icient 5 to use.
With the above and other ob; ects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in 10 the ~rpPntlP~ claims, it being understood that changes may be made in the form, size, proportions and minor details of construction without departing from the spirit or sacrif icing any of the advantages of the invention .

Now with more particular reference to the drawings, in its basic form, the invention involves transferring a copy 25 of a color photograph, picture or other artiale 14, such as an even, flat surface of a three dimensional article, to carrier sheet 12. Carrier sheet 12 could be made of transparent plastic material that may be, for example, .001 to . 005 inches thick and it could be made of paper or other 30 material that will withstand the temp~LCI~uLes n~cPqs~ry to remelt toner images 16.
In carrying out the method according to the invention, a copy of article 14 is made by a dry toner copier machine 10 thereby providing toner image 16 on carrier sheet 12.
35 Carrier sheet 12 is then moved to pressure and heat machine 20. Carrier sheet 12 is then supported on platen 22 of 21 g2~1 2 ~r~sDu~ ~ and heat machine 20 with toner image 16 in contact with a flat or even surface of entity 28. Heat machine 20 has pressure means 18 and heater 2 6 .
Heat and ~resDu~ are then applied to carrier sheet 12, 5 remelting toner image 16 and ~orcing toner image 16 against entity 28 80 that the remelted plastic of toner image 16 adheres to entity 28. Heat and pL~ u~ ~ can then be removed. Thus, an image of article 1~ will be affixed to entity 28 thereby forming a faithful reproduction of 10 original article 1~.. Several pictures or other articles could be arranged on copier machine 10 and copied on carrier sheet 12.
The foregoing specification sets forth the invention in its preferred, practical forms but the structure shown is 15 capable of modif ication within a range of equivalents without departing from the invention which is to be understood is broadly novel as is c~ c~te with the appended claims.
