Description

[Detailed description of the invention] A method for transferring graphics and/or character patterns The present invention relates to a method for transferring graphics and/or character patterns. Concerning methods consistent with explanations of species concepts.

Such a method is known from 5U-1350045A and is carried out from 60°C to 80°C. rubbed over or pressed onto a heated object at a temperature in the range of It is used in the production of thermal transfer material objects.

It allows you to transfer dry toner images to paper, plastic, tissue and ceramics. Methods are being taken to implement this. This well-known method has certain drawbacks, namely the Dry toner images fixed on heated objects often do not receive enough ink. There are drawbacks.

According to DE-O 83733385, an intermediate template was similarly produced by the method of electrostatic thermocopying. Other transfer processes are known. Such an intermediate template has the dry toner image side next. is coated with a commercially available adhesive using which the image toner adheres to the surface of the carrier. It is attached to the surface. After a certain fixation time, the intermediate template is pulled out and the transferred image is Fixed by varnish. In such cases, it is present as a plasticizer in commercial adhesives. Solvents are also used for transfer and fusing.

Finally, a thermal reversal printing process is known from DE-A3 28 47 702. Ru. Using this process, the sublimable ink present in the paper and forming the pattern is transferred to the cloth. Transferred to the base material or plastic treated surface, the back side of the sublimable ink is also used for structural purposes. Equipped with adhesive. Paper on which the pattern to be transferred has a sublimation ink and a structural adhesive cut out or stamped with an inverted mirror pattern from the auxiliary carrier The transfer is attached to the surface of the carrier that is mounted on and then printed with. and undergo heat treatment for fixation.

The quality of printed patterns can be improved by using sublimation inks instead of dry toners. is possible, but if the pattern to be transferred is cut out in the form of an inverted mirror or Or put up with the fact that it is mandatory to be launched and mounted on an auxiliary carrier It must be. The printed carrier is at least 60% plastic. The need to be made of solid material is also considered a further disadvantage.

It is therefore an object of the present invention to compensate for the above-mentioned disadvantages and to Carriers made of a wide range of different materials such as wood, plastic, and fabric This method allows for extremely simple and economical printing on surfaces in a short period of time. The object of the present invention is to devise a method that enables intensive color ink coverage.

The solution to the method problem mentioned at the outset is represented by the procedural steps of claim 1. It has characteristics.

When a soft carrier is used, an image of the original pattern is placed on the surface for its fixation. A method is adopted in which the image is transferred using a hot-melt adhesive foil. software like this It is contemplated that the carrier is preferably a fabric. However, leather, plastic Rustic leather cloth, neoprene, rubber, foamed plastic and plastic Cork sheets as well as carriers made of cork are also suitable for that purpose.

Another embodiment of the invention is that the adhesive is fixed to the back side of the transparent carrier by heat treatment. The dry toner image transferred directly from the intermediate template to the carrier is now reinforced and/or coated with a subsequently applied embossing foil. take measures to

The embossing foil shines through the toner, allowing the toner color to be heated using a new heat treatment. Can be strengthened or modified by subsequent application of embossing foil with . The embossing foil that is pulled out after heat treatment is Since it is firmly fixed only to the toner, it will not be pulled out from the toner.

Simplified transfer of the original pattern onto the carrier, allowing the drying process to be removed from the intermediate template. The toner image has an adhesive side of a transparent self-adhesive film, and the self-adhesive film is An adhesive film that is deposited on the surface of the carrier and remains on the carrier provides mechanical protection. have an effect.

Furthermore, the original pattern is first copied onto a transparent foil by a well-known method, and then Re-duplicate the film inverted from the transparent foil onto the intermediate template of paper coated with release agent. Measures will be taken to copy the information. Then, applying and fixing an image of the original pattern overlays it. This is accomplished by transferring and fixing onto the surface of a carrier using the method described above.

When printing on a transparent carrier, the dry toner image is also attached to the adhesive side of the transparent self-adhesive film. , transfer it to the back side of the transparent carrier, and fix it on the carrier. You can wear it.

Dry toner fused to carrier to change or enhance image color - Cover the image with embossing foil and remove the embossing foil after another heat treatment. Steps are taken to lift the image from the embossing foil and take on the color of the embossing foil.

Transferring the original pattern onto the fabric using a simplified method involves transferring the dry toner image onto the fabric. This can be done by direct transfer onto fabrics and, at least in the case of fabrics, by using a steam fixing process. become capable. The image becomes resistant to boiling at temperatures above 175°C.

Finally, a negative print of the original pattern is used as an embossing fork with a dry toner image. The toner is transferred to a polyethylene foil at a temperature of 120°C or higher, thereby All color inks on the embossing foil, including Glue over the entire area of the polyethylene foil and make a negative print of the original pattern or Polyethylene each separated image from the colored surface of the embossing foil. Because it is made on Renfoil, the original paper takes on the color of the embossing foil. The image of the turn can be created by lifting using the adhesive side of the self-adhesive film. Wear.

The invention with its advantages and characteristics is explained in the claims and in the following description of the embodiments with reference to the drawings. It becomes clear from the light.

Transfer of toner image from intermediate template onto transparent self-adhesive film and transparent carrier This is a transfer to the back side of the Yar.

FIG. 1 shows a medium consisting of a sheet of paper 11 with a double coating 12 of chromium stearate. A side view of the intermediate mold plate 10 is shown. The intermediate template 10 includes a conventional electrostatic thermal printer. A dry toner image 14 deposited and fixed by the printing process further occupies the position. Ru. To transfer the dry toner image 14, the intermediate template 10 includes a An embossing foil 16 is applied as shown in FIG. It overlaps the carrier sheet 17. The image of the intermediate template is shown in Figure 2a. It is transferred onto the embossing foil under the action of heat. An image with an intermediate toner image The bossing foil is in this state placed on the surface of the carrier 18 as shown in Figure 2b. He is fixed there by heat. For this operation, preferably from 80°C Temperatures between 120°C shall be used. The temperature values shown are available on the current market. It is suitable for hand-made toners. Toner whose processing temperature is lower than this If available, such toners can be used as well. embossing foy Due to the high affinity between the toner and the toner that is heated and fixed on the carrier, it is covered with toner. The part of the embossing foil that is not A cap with a surface that corresponds and corresponds to the color of the surface of the embossing foil. An image appears on the rear. In this way, you can print in any desired color. It's easy to make. The fused dry toner image placed on the template 10 is in a non-inverted form. Therefore, even on the carrier 18 shown in FIG. 20, it is in a non-inverted state, and FIG. Transfer of the fused dry toner image from the intermediate template 10 onto the fabric carrier 22 shows. For this operation, the dry toner image 14 is exposed to the thermal effect as shown in Figure 3a. is transferred to the hot melt adhesive foil 20 under . Such hot melt adhesive foil is Like the embossing foil mentioned above, it is commonly known and commercially available. . Typical processing temperatures are about 120°C.

Dry toner is used to transfer and fix the dry toner image onto the fabric carrier 22. A hot melt adhesive foil 20 with an image 14 is attached to the carrier 2 as shown in Figure 3b. 2, both the dry toner image 14 and the hot melt adhesive foil 20 are fixed onto the fabric. Heat is applied again to fix it in the tissue. As a result, the toner 14 and the hot melt The adhesive foil 20 is penetrated into the tissue as shown in FIG. onto the organization Transferring requires a temperature in the range of 140°C to 180°C, so hot-melt adhesive film is The use of a protective paper cover on the back side of the foil is advantageous. Such protective paper is tissue It is extracted after being transferred to . Like fabrics, leather, plastic leather, neo Prene, rubber, foam and plastic foils or cork and other soft Materials are treated similarly.

The application of a graphic or text pattern onto a transparent rigid carrier is shown in FIG. explained. A non-inverted fused dry toner image 14 as shown in FIG. 4a. An intermediate template 10 showing the dry toner image 1 is attached to the back side of the transparent carrier 24. 4 is fixed onto the carrier by application of heat as shown in FIG. Intermediate template 10 After removing the paper layer from the paper, it is ready for printing and is uninverted from the front side as shown in Figure 40. It is legible in this condition.

When a dry toner image is deposited in a non-inverted state on the front of a rigid carrier, an inverted A dry toner image must be deposited onto the intermediate template. This is done using a well-known method. , copy the original pattern onto a transparent film, and then reproduce it onto the intermediate template 10. This can be done by copying.

Then transfer and transfer to the front side of the carrier plate as described for Figure 4. The work to establish and establish the system continues.

An easy way to apply graphics or text patterns onto transparent carriers The method results from processing steps as already described in FIG.

For this purpose, an inverted image of the original pattern is again applied as a dry toner image, It is lifted off the intermediate template using adhesive foil 26 as shown in Figure 5b. Before The adhesive foil 26 is attached to a transparent carrier with a dry toner image adhered thereto. 24 so that it can be read correctly from the front in a non-inverted state. Ru.

Transfer methods not shown in the drawings start from the stage where the intermediate template is provided with a dry toner image. The dry toner image is then transferred directly onto the fabric. Heat treatment is still It is carried out using a temperature of 175°C or higher in the form of a film fixing system. This method uses evaporation-resistant paint. produce an image.

The method according to the invention avoids high costs and eliminates solvents that can be a nuisance to the environment. printing in a simple manner and very quickly on very different materials without the need for and make it possible. The special paper used for intermediate templates is relatively easy to make. , a special type of toner that can be easily transferred because the dry toner only weakly adheres to the special paper. Has advantages. The dry toner is fixed on the carrier by transfer under the action of heat. It will be worn. Transfer is carried out using a transparent adhesive film such as Scotch tape In cases where the image is protected against atmospheric substances and acids and Resistant to potash. Fixing of dry toner images using hot melt adhesive foils provides boiling and washing resistance to the original pattern image on the fabric. Medium according to the present invention An electrostatic thermal printing process can be used to create intermediate templates as well as intermediate templates. Laser printing can also be applied to special paper used for. Laser print like this The original pattern can be created directly on the screen by using a data processor.

The invention is useful for small-scale editing, especially when only a few prints are needed. can be used economically and commonly. Regardless of this, in such a way The written descriptions and photographs are resistant to frost, light and atmospheric substances, and are mechanically resistant. Protection against mechanical damage is only required when applied to the top surface of the carrier; Protection such as the use of heat-melted embossing foil already increases the strength of the collar. Reinforcement, especially in accordance with the large number of colored embossing foils available It is possible to create the desired color shading.
