• soft carriers are used to fix them, it is provided that the image of the original is transferred to the surface with the aid of a hot-melt adhesive film.
• Textiles are preferably used as soft carriers.
• carriers made of leather, synthetic leather, neoprene, rubber, foam, plastic film and cork are also suitable for this.
• a further embodiment of the invention provides that the dry toner image transferred from the intermediate template directly onto the back of a transparent support by heat treatment and fixed on it is intensified and / or covered by subsequent application of stamping foils with renewed heat treatment.
• the color of the toner can be intensified or changed by subsequently applying an embossing film with renewed heat treatment, since the embossing film shines through the toner.
• the embossed stamped after the heat treatment The film cannot be removed from the toner, since it only forms a firm connection with this and not with the carrier.
• a simplified transfer of the original template to a carrier provides that the dry toner image is removed from the intermediate template with the adhesive side of a transparent adhesive film and that the adhesive film is glued to the surface of the carrier, as a result of which the adhesive film left on the carrier offers mechanical protection .
• the original template is first copied onto a transparent film in a known manner and that the transparent film is copied the wrong way round onto an intermediate template made of paper coated with a release agent. Then the image of the original template is applied and fixed by transfer and fixing in the manner already mentioned on the surface of the carrier.
• the dry toner image can also be lifted off with the adhesive side of a transparent adhesive film and can be transferred to the back of the transparent substrate and fixed to it.
• the dry toner image fixed on the carrier is coated with an embossing foil and is lifted off the embossing foil after a further heat treatment, the image assuming the color of the embossing foil.
• the transfer of an original image to textiles is possible in a simplified manner in that the dry toner image is transferred directly to the textiles and that a water vapor fixation is used for fixation, at least for textiles.
• the images become cook-proof at temperatures above 175 ° C.
• a negative print of the original image can be created by transferring the embossing foil provided with the dry toner image to a polyethylene foil at temperatures above 3.20 ° C., so that the entire color of the embossing foil, including the toner, on the polyethylene foil after the carrier sheet has been lifted off adheres, and that with the adhesive side of an adhesive film the image of the original image is lifted in the color of the embossing film in order to produce a negative print of the original image on the polyethylene film or an image left out of the colored surface of the embossing film.
• Fig.l an intermediate template with a dry toner image produced on electrostatic thermal copying
• FIG. 5 shows the transfer of the dry toner image from the intermediate template to a transparent adhesive film and the transfer and fixing to the back of a transparent carrier.
• Fig.l is a side view of an intermediate template 10 is shown, which is provided from a sheet of paper 11 with a double coating 12 of chrome stearate. Furthermore, on this intermediate original 10 there is a dry toner image 14 which has been applied and fixed in a conventional electrostatic thermal copying process.
• the intermediate template 10 is placed with the image side onto an embossing film 16, which in turn lies on a carrier sheet 17.
• the intermediate toner image is transferred to the embossing film according to FIG. 2a.
• the embossing film provided with the intermediate toner image is now placed on the surface of a carrier 18 according to FIG. 2b and fixed by heat.
• a temperature between 80 ° C and 120 ° C is preferably used.
• the specified temperature values are suitable for the toners currently available. If toners become available whose processing temperatures are lower, they can be used in the same way.
• FIG. 3 shows the transfer of a correct and fixed dry toner image from an intermediate template 10 to a textile carrier 22.
• the dry toner image 14 is transferred to an adhesive film 20 under the influence of heat.
• Such hot-melt adhesive films like the previously mentioned stamping films, are generally known and commercially available.
• the usual working temperature is around 120 ° C.
• the hot-melt adhesive film 20 with the dry toner image 14 is placed on the carrier 22 and heat is applied again in order to transfer and fix the dry toner film to the textile carrier 22, in order to heat both the dry toner image 14 and the adhesive adhesive film 20 in to fix the textile fabric.
• Both the toner 14 and the adhesive adhesive film 20 penetrate into the tissue, as can be seen from FIG. 3c. Since temperatures between 140 ° C. and 180 ° C. may be necessary during the transfer to the fabric, the use of a protective paper on the back of the adhesive adhesive film is expedient. This protective paper is peeled off after transfer to the fabric.
• other soft materials such as leather, synthetic leather, neoprene, rubber, foams and plastic films or cork and others are treated in the same way.
• FIG. 4 a The intermediate template 10 shown in FIG. 4 a with a correct and fixed dry toner image 14 is placed on the back of the transparent carrier 24 and the dry toner image 14 is fixed on the carrier by the action of heat, see FIG. 4 c. After the paper sheet of the intermediate template 10 has been removed, the printing is finished and can be read from the front in the correct direction, see FIG. 4c.
• the dry toner image is to be applied correctly on the front surface of a hard carrier, it is necessary to apply an inverted dry toner image to the intermediate template. This can be done in a known manner by copying the original template onto a transparent film and then copying it to the intermediate template 10. Then the transfer and fixing takes place on the front of the carrier plate, as described with reference to FIG. 4.
• a simplified method for applying an image or writing pattern to a transparent carrier results from the procedure described in FIG. 5.
• a reverse image of the original is also attached to an intermediate template 10 as a dry toner image and, according to FIG. 5b, this is lifted off the intermediate template with the aid of an adhesive film 26.
• This adhesive film 26, together with the dry toner image adhering to it, is glued to the back of the transparent carrier 24 and is therefore legally readable from the front.
• a transfer method is based on an intermediate template provided with the dry toner image and transfers the dry toner image directly to textiles.
• the heat treatment takes the form of a steam fixation, using temperatures above 175 ° C. This creates a boil-proof image.
• the measures of the invention make it possible to print on a wide variety of materials in a very simple and very fast manner while avoiding higher costs, no environmentally harmful solvents or the like being required.
• the special paper used for the intermediate template is relatively easy and inexpensive to produce and is of particular advantage since the dry toner adheres only very weakly to the special paper and is therefore easy to transfer.
• the dry toner is fixed on the carrier. If the transfer is done with transparent adhesive films, such as. B. Scotch tape, the images are weatherproof as well as acid and alkali resistant due to the covering with the adhesive film.
• the dry toner image is fixed with the aid of hot-melt adhesive films, the image of the original documents on textiles becomes resistant to cooking and cleaning.
• the intermediate template can be generated directly on the screen.
• the invention is particularly economical and can be used universally even for short runs, especially if only a very few prints are required. Nevertheless, the inscriptions or illustrations produced with it are frost, loan and weather-resistant and, if they are attached to the top of carriers, only need protection against mechanical damage that is already provided with hot-melt adhesive films and adhesive films.
• the color intensities can be intensified and in particular any color tones can be produced in accordance with the large selection of colored embossing foils.
