Definitions

  • the present invention is a coating composition for use in a sublimation ink image transfer process, wherein the properties of the coating composition for the printing paper used make it possible to save costs and improve the quality of the coating Image or print pattern to improve significantly.
  • the image is preferably printed on paper by means of printing processes, such as offset, gravure, flexographic, screen or inkjet printing with sublimation ink, from where it is transferred to the fabric by means of pressure and heating.
  • printing processes such as offset, gravure, flexographic, screen or inkjet printing with sublimation ink
  • the thermal sublimation printing technique is increasingly being used for heat-induced transfer of an image or pattern to synthetic fabrics and dishes, such as cups, cups, plates, etc., since this technique has many applications Punches for customer-specific impressions and also allows a significant cost savings for the product.
  • image transfer from the paper to the article to be printed in the sublimation printing process is predominantly on fabrics having synthetic surfaces, such as the like. Polyester fabric, or porcelain and metal surfaces with polyester, polyurethane or similar surface coatings.
  • Synthetic fabrics however, have the intrinsic property of undergoing material shrinkage of about 5% at high temperatures in the range, for example, between 200 ° C and 220 ° C, and 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 yarns and material composition). Since the image is transferred to the tissue during the entire pressing time, the color sublimates gradually, which is also dependent on the porosity of the tissue structure. While the image transferring paper does not shrink and the image retains its original dimensions, the tissue shrinks throughout the ink sublimation period.
  • the tissue is shrunk in advance.
  • the material is pressed before the pressing process at the same pressure and temperature as used in the actual compression molding process.
  • the fabric substantially shrinks with the paper even before the actual pressing, so that any remaining shrinkage that may still occur in the ink sublimation step does not affect the press-printing process.
  • the previously mentioned method can in many cases result in tissue damage since the fabric undergoes two cycles of high temperature and high pressure, one cycle for shrinkage and the second cycle for image transfer. This can lead to a flattening of the fabric threads and a burning (yellowing) of the fabric due to the high temperature. The fabric may thereby lose some of its original properties, such as its texture, flexibility and brightness.
  • the paper which is mainly used for image printing, is due to the low cost of a commercial paper, as it is used in everyday life for conventional printing. 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 allow only low resolution prints, with low intensity and low contrast colors. In addition, as the ink evaporates through the fibers of the paper to the back of the paper and leaves traces of paint on the press, this causes a weaker print to be transferred to the substrate (fabric, dishes, etc.) during the next hot transfer of the same image. To avoid this problem, it is necessary to separate the motif paper from the press by 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 have been developed with one or more coatings suitable for ink jet printing using sublimation ink, resulting in higher resolution, more intense and vivid colors, and a higher contrast for fabric, dish and heat transfer other surfaces can be achieved.
  • coatings suitable for ink jet printing using sublimation ink resulting in higher resolution, more intense and vivid colors, and a higher contrast for fabric, dish and heat transfer other surfaces can be achieved.
  • a coat of paper consisting of one or more lacquer layers may comprise a sealing layer to reduce the amount of ink vapor permeating the fibers of the paper.
  • the sealing layer can prevent the escape of ink vapor at the back side of the paper, thereby eliminating the need to use a release sheet.
  • white off-set paper is usually coated for the application described above, resulting in a paper having a weight of 70 g / m 2 to 90 g / m 2 .
  • This paper is made predominantly of short fiber pulp and in a composition designed for good inkjet and laser print quality.
  • the paper has undesirable porosity for use in sublimation ink printing, which allows the ink vapor heated in the press to seep through the paper to the back.
  • the present invention proposes to solve the above-mentioned problems and disadvantages as well as objects by the use of a coating specially developed for use on paper having a basis weight equal to or greater than 50 g / m 2.
  • the present invention particularly proposes a specific one Coating for a paper for inkjet printing, gravure printing, flexo printing or screen printing with sublimation ink before.
  • the inventive coating provides a variety of technical and economical advantages over other coatings used for the same purpose.
  • the present invention provides a special coating for paper or a coated paper, which envelopes 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, wherein the image to be printed first on the coated Paper is printed and then transferred from this to the object to be printed.
  • the coating is suitable for use in inkjet printing, screen printing, flexographic printing and gravure printing processes.
  • the invention relates to a specially developed coating which is fixed on the article to be printed by the heat and the residual moisture of the paper and the coating.
  • the coating encloses the surface structure of a surface to be printed, in particular fibers of a fabric structure, so that an improvement of the image resolution can be achieved.
  • the special coating for the paper according to the invention also eliminates the step of pre-shrinking an article to be printed, whereby the original texture and flexibility of the article to be printed and its whiteness are maintained.
  • the invention ensures an increased fixing rate of the ink on the object to be printed, and enables a marked increase in the light resistance of the print against exposure to ultraviolet light and washing.
  • Vegecoi 10A (trade name, supplier: Ingredion Incorporated, Brazil), the Vegecoi 10A being present in an amount of 80 to 95% by weight and the Penetrose 80 in an amount of 5 to 20% by weight can.
  • the residual moisture of the coating is in a range between 5 wt.% And 7 wt.%.
  • the coating of the paper may be carried out by the application of the following methods: brushing, spraying, in particular with an air knife, gravure rolls or the like.
  • the application rate can be in the range between 80 m / min and 100 m / min and the drying 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 so that the coating 1 conforms to the fibers 2 of the fabric to be printed (FIG. 2) and adheres to it, so that the sublimation can take place by a direct contact and not only at the points of contact (Fig. 1), as in commercial coatings. 3
  • any image with sublimation ink can be printed on the coated paper by the aforementioned processes (ink jet printer, screen printing, flexographic printing and gravure printing process), with the sublimation ink applied to the coating 1 predominantly the surface of the coating 1 is fixed.
  • the unique properties of the coating make it possible that when so that it is printed on a fabric, the heat in the sublimation pressure can be exploited to bring in fractions of a second the residual moisture in the paper and the coating composition to evaporate.
  • the coating 1 is activated so as to soften and conform to the fabric structure 2 (FIG. 2) so as to surround the top of each fabric fiber 2 which is in contact with the coating 1.
  • the coating 1 is dried by the heat so that the coating 1 is easily adhered to the fabric. This adhesion is sufficient to stably hold an image or pattern on the fabric during the time that the sublimation and fixation of the ink on the fabric fibers 2 takes place.
  • the coated paper After pressing, the coated paper easily peels off the fabric without residue and can be removed.
  • This unique feature simplifies the production process to just one step and eliminates the need to pre-shrink the fabric. This allows great savings in production time and eliminates the full cycle of pre-shrinking, which doubles production efficiency and cuts power consumption and machine wear by almost half.
  • the unique property of the coating which ensures that each fiber of the tissue in its middle contact surface surrounded by the coating , allows the ink to remain in direct contact with the fiber during the sublimation printing process. This increases the contact surface of the ink to the fabric fibers, whereby the fixing speed of the sublimed ink to the fabric can be increased by 20% without the ink being lost as steam due to the higher surface area of the coating with respect to the fabric yarns. This causes the fabric printed with the coating coated paper to exhibit more defined edges, contours and color gradients, higher color contrasts, higher color depth and vividness. Therefore, this new coating can achieve a significant improvement in all visual aspects.
  • the coating provides for the printed fabric, in particular the greater ink-retaining area for the fabric fiber, more extensive adhesion to the surface of the fabric fibers, higher color throughput of the fabric, higher contrast, higher vividness and intensity of the colors and a higher image resolution, the light resistance of the pattern is increased by at least 20% with respect to exposure to ultraviolet light and the resistance to washing fading.
  • a fabric printed therewith can provide a quality superior to the prior art, both in terms of visual perception of the pattern itself, and durability, print quality and wear resistance With regard to exposure to UV light, washing and its resistance to factors such as perspiration, friction, etc.

Abstract

La présente invention concerne un procédé d'impression par application de force de pression pour transférer une image avec un papier couché de manière spécifique et une encre de sublimation, selon lequel un motif ou une image est imprimé(e) sur un papier couché avec le revêtement spécifique pour en être ensuite transféré(e) sur l'article à imprimer. Lors de son utilisation dans le cadre d'un procédé d'impression à jet d'encre, de sérigraphie, d'héliogravure ou de flexographie, le revêtement empêche l'encre imprimée de pénétrer le papier du fait de la porosité du papier. Le transfert d'image du papier couché à l'objet à imprimer s'effectue par apport de chaleur et d'une pression exercée à une température comprise enter 200 et 230°C, le revêtement étant activé par la chaleur, de manière à être rendu mou et de sorte qu'il s'adapte à la surface à imprimer et y est fixé de manière à adhérer aisément. Ce qui permet un transfert direct de l'encre de sublimation sur la surface de contact de la surface à imprimer, le revêtement étant de ce fait supérieur aux autres revêtements présents sur le marché.
