Definitions
- the present invention is a coating composition (coat) for use in a method for image transfer by means of sublimation ink, wherein it is possible due to the properties of the coating composition (coat) for the printing paper used to save costs and the quality of the image or print pattern clearly to improve.
- the press printing process for image transfer to tissue has been known for a long time.
- the image is preferably printed on paper using printing processes such as offset printing, gravure printing, flexographic printing, screen printing or ink-jet printing with sublimation ink, from where it is transferred to the tissue by means of printing and heating.
- the thermal sublimation printing technique is increasingly used for the heat-induced transfer of an image or pattern onto synthetic fabrics and dishes, such as cups, mugs, plates, etc., since this technique has a wide range of applications for customer-specific impressions and also enables considerable cost savings for the product.
- the image transfer from the paper to the object to be printed takes place predominantly on fabrics with synthetic surfaces, such as e.g. Polyester fabric, or porcelain and metal surfaces with polyester, polyurethane or similar surface coatings.
- synthetic fabrics have the intrinsic property that they experience a material shrinkage of approx. 5% at high temperatures in the range of, for example, between 200 ° C. and 220 ° C. and at longer pressing times, for example in the range of 15 to 30 seconds.
- this shrinkage varies between 3% and 10% depending on the type of fabric (warp and weft threads and material composition). Since the image is transferred to the fabric during the entire pressing time, the color gradually sublimates, which also depends on the porosity of the fabric structure. While the paper transferring the image does not shrink and the image retains its original dimensions, the tissue shrinks during the entire ink sublimation period.
- the fabric is shrunk in advance. Before the pressing process, the fabric is pressed at the same pressure and temperature as is used in the actual pressing process. As a result, the tissue essentially shrinks even before the actual pressing with the paper, so that any remaining shrinkage that can still occur in the ink sublimation step does not impair the pressing process. Nevertheless, the above method can be used in many cases lead to tissue damage since the tissue is subjected to two cycles of high temperature and pressure, one cycle for shrinkage and the second cycle for image transfer. This can lead to flattening of the fabric threads and burning (yellowing) of the fabric due to the high temperature. The fabric may lose some of its original properties, such as its texture, flexibility and brightness.
- the paper which is mainly used for image printing, is a commercial paper because of the low cost, as it is also used in everyday life for conventional printing processes. These are called “off set” or “bond papers” and weigh 70 g / m 2 or 90 g / m 2 . Despite their widespread use, these papers only allow prints in low resolution, with colors of low intensity and weak contrast. When evaporated, the ink also diffuses through the fibers of the paper all the way to the back and leaves traces of color on the press. This causes a weaker print to be transferred to the substrate (tissue, dishes, etc.) during the next hot transfer of the same image. In order to avoid this problem, it is necessary to separate the motif paper from the press by means of additional paper sheets which absorb the continuous ink vapors. However, these sheets of paper can only be used a few times and must be replaced regularly.
- coated papers with one or more coatings have been developed which are suitable for ink jet printing using sublimation ink, so that a higher resolution, more intense and vivid colors and a higher contrast for the hot transfer to fabric, tableware and other surfaces can be achieved.
- a higher resolution, more intense and vivid colors and a higher contrast for the hot transfer to fabric, tableware and other surfaces can be achieved.
- a coating (coat) of paper which consists of one or more layers of lacquer, can comprise a sealing layer so that the amount of ink vapor that penetrates the fibers of the paper is reduced.
- the sealing layer can prevent the escape of ink vapor on the back of paper, eliminating the need to use a separator sheet.
- white copy paper (off-set) is usually coated for the application described above, which results in a paper with a weight of 70 g / m 2 to 90 g / m 2 .
- This paper is predominantly made from short fiber pulp and in a composition that is designed for good inkjet and laser print quality.
- the paper has an undesirable porosity for use in ink-jet printing with sublimation ink, which enables the ink vapor heated in the press to seep through the paper to the rear.
- a greatly improved image quality is to be achieved in the press printing process.
- the present invention proposes to solve the aforementioned problems and disadvantages as well as objects by using a coating which was specially developed for use on paper with a basis weight equal to or greater than 50 g / m 2.
- the present invention particularly proposes a special one Coating for a paper for inkjet printing, gravure printing, flexographic printing or screen printing with sublimation ink.
- the coating according to the invention provides a variety of technical and economic advantages over other coatings that are used for the same purpose.
- the present invention provides a special coating for paper or a coated paper, which envelops the contours of the surface topography of an object to be printed, in particular fibers of a fabric structure, and is suitable for printing with sublimation ink, the image to be printed first being coated onto the coated one Paper is printed and then transferred from this onto the object to be printed.
- the coating is suitable for use in inkjet printing, screen printing, flexo printing and gravure printing.
- the invention further relates to a specially developed coating which is fixed on the object to be printed by the heat and residual moisture of the paper and the coating.
- the coating encases the surface structure of a surface to be printed, in particular fibers of a fabric structure, so that an improvement in the image resolution can be achieved.
- the special coating for the paper according to the invention the step of pre-shrinking an object to be printed is also omitted, as a result of which the original texture and flexibility of the object to be printed and its degree of whiteness are retained.
- the invention ensures an increased rate of fixation of the ink on the object to be printed and enables a significant increase in the lightfastness of the print against exposure to UV light and during washing.
- the modified corn dextrin can be a corn dextrin modified with starch, in particular pregelatinized starch.
- a modified Corn dextrin a blend of Vegecol 10A (trade name, supplier: polyamides - Brazil) and Penetrose 80 (trade name, supplier: Ingredion Incorporated, Brazil), where the Vegecol 10A can be present in an amount of 80 to 95% by weight and the Penetrose 80 in an amount of 5 to 20% by weight.
- the residual moisture of the coating is in a range between 5% by weight and 7% by weight.
- the paper can be coated using the following methods: brushing, spraying, in particular with an air knife, gravure rollers or the like.
- the application rate can be in the range between 80 m / min and 100 m / min and drying can take place in an oven at a temperature of 100 ° C to 120 ° C. Maintaining the residual moisture is of fundamental importance in this production process, since the residual moisture of the composition activates the coating when heated in such a way that the coating 1 envelops the fibers 2 of the fabric to be printed according to the contour ( Fig. 2 ) and adheres to it so that sublimation can take place through direct contact and not just at the points of contact ( Fig. 1 ), as with commercially available coatings 3.
- each image with sublimation ink can be printed on the coated paper using the previously mentioned processes (inkjet printer, screen printing, flexographic printing and gravure printing method), the sublimation ink applied on the coating 1 predominantly on the surface of the coating 1 is fixed.
- the unique properties of the coating allow that when so that it is printed on a fabric, the heat from sublimation printing can be used to evaporate the residual moisture in the paper and the coating composition in a fraction of a second.
- the coating 1 is activated in such a way that it becomes soft and adapts to the fabric structure 2 ( Fig. 2 ) so that it surrounds the top of each fabric fiber 2 that is in contact with the coating 1.
- the coating 1 is dried by the heat, so that the coating 1 is fixed to the tissue in a slightly adherent manner. This adhesion is sufficient to hold an image or a pattern stable on the tissue during the time in which the sublimation and fixing of the ink on the tissue fibers 2 takes place.
- the coated paper can be easily removed from the fabric without residue and can be removed.
- This unique property simplifies the production process in just one step and eliminates the step of shrinking the fabric. This enables great savings in production time and eliminates the complete pre-shrink cycle, doubling production efficiency and reducing power consumption and machine wear by almost half.
- the unique property of the coating which ensures that each fiber 2 of the fabric is surrounded in its central contact area with the coating 1, whereas, in contrast to this, with commercial coatings 3 there is only a tangential contact with the fabric fibers 1 ( Fig. 1 ), provides a significant improvement in image resolution because the formation of the coating on the tissue fibers allows the positioning of the image with respect to the tissue to be maintained so that the sublimation ink at each pixel transfers to the same location on the tissue throughout the process becomes.
- the unique property of the coating which ensures that every fiber of the fabric surrounds the coating in its middle contact area enables the ink to remain in direct contact with the fiber during the sublimation printing process. This increases the contact surface of the ink on the fabric fibers, which can increase the rate of fixation of the sublimed ink on the fabric by 20% without the ink being lost as steam due to the higher surface area of the coating with respect to the fabric threads. This means that the fabric printed with the paper coated with the coating shows more defined edges, contours and color gradients, higher color contrasts, a greater depth of color and liveliness. Therefore, with this new coating a significant improvement of all visual aspects can be achieved.
- the coating provides for the printed fabric, in particular due to the larger ink attachment area for the fabric fiber, a greater adhesion to the surface of the fabric fibers, a higher color throughput of the fabric, a higher contrast, a higher vividness and intensity of the colors and a higher image resolution, the light resistance of the pattern to exposure to UV light is increased by at least 20% and the resistance to fading during washing.
- a fabric printed with it can provide a quality which is superior to the prior art, both in terms of the visual perception of the pattern itself, and in terms of the durability, the printing quality and its wear resistance in the Regarding exposure to UV light, washing and its resistance to factors such as sweat, friction, etc.

l'objet à imprimer présente sur la surface à imprimer une structure de tissu, de sorte que, lorsque le revêtement est activé et devient mou, celui-ci est adapté à la structure de tissu, ce qui a pour effet que la face supérieure de chaque fibre de tissu, qui est en contact avec le revêtement, est enrobée et le revêtement est fixé au tissu de manière à adhérer aisément. - Procédé d'impression par application de force de pression selon l'une quelconque des revendications 4 à 6,
caractérisé en ce que
une image ou un motif quelconque est appliqué avec une encre de sublimation sur le papier couché au moyen de procédés d'impression à jet d'encre, de sérigraphie, d'héliogravure ou de procédés de flexographie, dans lequel l'encre de sublimation est appliquée sur le revêtement et fixée de manière stable sur la surface de revêtement. - Procédé d'impression par application de force de pression selon l'une quelconque des revendications 4 à 7,
caractérisé en ce que
du fait de l'utilisation du papier couché dans le procédé d'impression par application de force de pression, aucun procédé de retrait préalable de l'objet à imprimer n'est réalisé en amont du transfert d'image. - Procédé d'impression par application de force de pression selon la revendication 6,
caractérisé en ce que
pour la structure de tissu, chaque fibre de la structure de tissu, pendant le transfert d'image depuis le papier couché, est enveloppée au moins en partie avec le revêtement, de sorte que l'encre de sublimation est en contact direct avec les fibres, de sorte que la structure de tissu imprimée de l'objet à imprimer présente des bords, contours, dégradés de couleurs et contrastes de couleurs définis.
