Process for communicating visual information

The invention relates to a method for conveying visual information and is particularly directed to a method for the recovery of a carrier, for example a plastic film., For example a xerographic process for producing an image is exposed on it, using the image-bearing Carrier for its intended purposes and then removing the image from the carrier by use a solvent for the xerographic Image-forming particles so that the carrier is suitable for reuse.

It is becoming increasingly important to reuse raw materials and to preserve natural raw material sources. Sin raw material or a natural source of raw material that is in appalling This is the paper used in offices. Often times, a large number of copies will be made of a document put into circulation, studied and then thrown away, Such a wasteful situation can be avoided by following the present Invention "erases" the carrier carrying the information material in the truest sense of the word, so that the carrier can be used again and again for repeated use.

The only attempt to conserve natural resources such as paper, particularly the large amount of informational paper that crosses desks and is then read and thrown away, is to collect this paper for reprocessing in the paper mill, ie for "recycling" subject. All of this can be avoided by the present invention by using a carrier that is "erased" or "erased" or made reusable by some method that can be performed in the field. For example, the reusable carrier can be read, returned to a central processing point and renewed or regenerated there. The invention also finds advantageous application for copies of files which are erased after a suitable period of time, whereby the recovered material can be reused.

According to a preferred embodiment of the invention, a carrier is provided which can record an information image in is able to. A variety of supports can be used, such as paper or other core material containing the provides the necessary background for the picture and in which the material is covered with the help of a film or a layer

or is covered in some other way, which has properties for releasing the information image, if this with is brought into contact with a suitable solvent. Where the information image is created by ink or paint, the appropriate color solvent is used, regardless of whether the ink or color is liquid or is applied in particle or powder form.

To generate the image on paper, reference should be made, for example, to the so-called xerocopy process, but this expression is to be understood in the most general sense for the generation of an image on a carrier, where in particular d ± <* use of a particle precipitate comes into consideration, which is described in their orientation correspond to the image on the original, whereupon the particles are fixed. The carrier carrying the image can then be viewed, stored, filed in files or used in some other way until the point in time when it is advantageous to return the carrier to its original, unprinted state. This is achieved by using a suitable solvent, as indicated above, the carrier then being available for further future use.

The invention will be explained in more detail in connection with the drawings.

These show in

Fig. 1 is a schematic representation of the method according to the invention; and in

ORIGINAL INSPECTED

In the drawing, the reference numeral 10 generally designates a carrier which can have the most varied of shapes, although preferably in the form of Figure 2, the numeral 11 being a paper or other core material referred to, which is sandwiched between two outer film coatings 12 and 13, which according to an embodiment of the Invention consist of "Mylar", which is a from E.I. DuPont de Nemours & Co. trades ethylene terephthalate. Usually owns the paper has a thickness on the order of 0.49 to 0.0735 mm (0.02 to 0.003 inches) and has surface dimensions according to the intended use, e.g. 208.25 by 269.5 mm (8 1/2 inches by 11 inches), 208.25 by 318.5 mm (8 1/2 inches by 13 inches), etc. The film coatings 12 or 13 can be on the order of Fractions of a millimeter, such as 0.049 to 0.00245 mm (0.002 to 0.0001 inches). Films 12 and 13 are bonded to the core 1 by a variety of methods, such as adhesion, extrusion, or the like.

Such a carrier is then fed to a suitable device for recording an image, which is shown in the drawing is indicated schematically by the block 14. A variety of devices and methods can be used, for example xerocopying, a process from Xerox Corporation, or printing using conventional presses. The finished product bears the image as indicated schematically at 15, this product now also being shown in FIG. 1 10 'is designated. For example, it can be an office document trade that is put into circulation and whose lifespan is limited. Instead of this information sheet Throwing in the trash, it is put back in a basket or other suitable container and

in the reactivation or regeneration station 16 for Restoration returned. This can be a press or some other tape-contacting device using a solvent suitable for removing the image. Most of them today The Xerox machines used are toluene as the solvent for the toner particles used there or tetrachlorethylene. The characteristics of the solvent are best expressed as a function of those that produce the image Set media.

In practice, the present invention uses the xerographic reproduction method in which the surface of the carrier is not changed, as is the case with printing presses or other impact printing units Case is.

Claims (2)

Claims f 1 ,; Method of reproducing visual information, characterized by the following levels: Producing a copy of a first original image on a carrier with a non-photoconductive ink Surface by means of a device which does not permanently impair the physical properties of that surface ; Treating the wearer independently and apart from the facilities for creating the copy of the image to provide visual information for a reader; Remove the copy of the image from the surface without affecting the properties of the surface around the To be able to reuse carriers in a similar way; Producing a copy of a second original image on the carrier; and Treating the carrier while it is carrying the second original image as in the first treatment stage. 2. The method according to claim 1, characterized in that the generation step is the production of a latent electrostatic image on a non-photoconductive dielectric surface of a dielectric support and the subsequent development of this image includes. 609632 / Ü83S
