Transfer printing film prepared by means of digital printing and preparation method and application thereof

Abstract

The embodiment of the invention discloses a transfer printing film prepared by means of digital printing. The transfer printing film comprises a carrier membrane, a water-borne wax layer and a color image-text layer which are superposed in sequence. The embodiment of the invention further discloses a preparation method of the transfer printing film prepared by means of digital printing and an application of the transfer printing film. According to the transfer printing film prepared by means of digital printing and the preparation method and application thereof, the transparent visual inspection problem of image-text printed by the transfer printing film, the problem of micro-distortion transfer printing of the transfer printing film, the problem of printing plate omission, the problem of reducing printing procedures and lowering losses and the problem of efficient industrial production conventionally are solved, and the transfer printing film and the preparation method and application thereof are particularly suitable for small-single and short-single low-cost operation; the problems of white ink underpainting and glue setting of a transfer printing function layer are also solved; the problem of combining adhesion of the array powdered ink color image-text layer and a separating agent coating and the problem of separating the array powdered ink color image-text layer and the separating agent coating from a carrier base membrane together are even solved; and moreover, volatile organic compounds (VOC) are hardly generated, and therefore the printing environmental protection property is greatly improved, and epoch-making significance is achieved.

Description

technical field [0001] The invention relates to a transfer printing technology, in particular to a transfer printing film prepared by digital printing and its application in injection transfer printing in a mold or / and thermal transfer printing outside a mold. Background technique [0002] Traditional printing processes such as screen printing, letterpress printing, gravure printing, and offset printing are widely used in the printing industry, and are very suitable for large and long orders, and are also familiar to people. Emerging printing technologies derived from the cross-integration of traditional printing technology and other disciplines and industries have also been continuously developed, and transfer printing is one of the most representative ones. [0003] The printing method that uses appropriate conditions, such as temperature, pressure, time, etc., to transfer and solidify the graphics on the intermediate carrier to the substrate is collectively called transfe...

Problems solved by technology

However, the piezoelectric inkjet printing machine and printing ink used in it also have flaws. For example, the speed of the piezoelectric inkjet printing machine is extremely slow. Just in theory; another example: high ink price, high consumption, short nozzle life, high overall cost, and no industrial productivity at all; another example: water-based dye ink or water-based pigment ink does not have white ink, so it cannot be set White background, if the white background is set offline, it cannot be accurately overprinted, and it will definitely cause chemical intrusion, and if UV ink is used, in addition to lower efficiency, there is also the problem of layer separation between UV ink and glue

[0009] Looking at the preparation process of domestic transfer film, it is not that there are problems of long process, time-consuming, and large waste in the traditional process. production, there are objective limitations
