Definitions

• the invention relates to a plastic film which can be printed using digital printing technology, in particular self-adhesive plastic film, which on the back with a Adhesive layer and a siliconized cover is provided as well Production of the printed film from paper or plastic (film).
• the invention has for its object a printable with digital technology
• To create plastic film with a health-friendly ink is printable and gives a perfect print image. It is also said to be a possibility for the production of a plastic film printed in digital printing.
• the The surface of the film is covered with a thin film of an acrylate polymer. It the result is a highly transparent and high-gloss polymer layer.
• an acrylate polymer a copolymer of butyl acrylate and a methyl methacrylate is used.
• the shares of the copolymer are preferably 50% by weight of butyl acrylate and 50% by weight Methyl methacrylate. It was found that such a plastic film is very good at Digital printing technology is to be printed with low solvent printing inks. A run of the Printing inks or other printing errors do not occur.
• the acrylate polymer is used as an aqueous dispersion applied to the surface of the film and then at a temperature of Dried 90 ° to 100 ° C. Higher temperatures can damage the Lead decorative film. If the temperature is too low, the copolymer cures unsatisfactory.
• the polymer can be applied to the film in the engraving system take place, which is followed by drying. With the engraving system, the dispersion by a rotating one with an engraved structure on its surface provided metal cylinder applied to the film web. The dried layer does not stick, so that the film can be rolled up into a roll in the usual way.
• the film is fed to a digital printer, which is equipped with a low solvent printing ink works, and the printing process is carried out. It turned out that a very good print image can be printed and that the film also a Has a surface with high resistance.
• Printing inks are preferred on Lactic acid base used. These printing inks can work very well on one with the Acrylic coated film can be processed. This is a Printing ink with low volatile organic solvents on an organic basis (Lactatbasis). The inks are available as low-volatile solvent ink, low-solvent ink and ecosolvent ink and called mild solvent ink.
• a so-called decorative film which consists of a PVC film on the back provided with an adhesive layer and a siliconized paper cover is fed to an engraving device and there with a thin film from a aqueous dispersion of a copolymer of butyl acrylate and methyl methacrylate coated.
• the PVC film is transparent or colored white during its manufacture, to form a good printing pad. It is also possible to use a different color use colored film if this is useful for later printing is.
• the decorative film is attached to the engraving device subsequent continuous oven dried at 96 ° C. The drying time is 30 Seconds.
• the dry decorative film is fed to a digital printer and there under Use of a low-solvent printing ink based on lactic acid derivatives printed. An excellent print image was achieved on an extremely resistant surface.
• the process is particularly suitable for the production of photo-realistic prints.
