Abstract

Provided is a substrate transfer printing layer structure with good finish by shortening the time and labor required for printing.
The printing layer structure for substrate transfer is to transfer a high-quality printing layer to a substrate quickly. A TPU protective layer is bonded to the PET separate type film bottom layer, and a resin layer is bonded to the TPU protective layer. Furthermore, a color, a design, and a pattern are printed on the resin layer by PC inkjet to form a print layer. Further, when the printed layer is bonded to the substrate by thermal transfer and the PET separate type film bottom layer is peeled off, the printing is completed and the surface forms a friction-resistant printing structure.

Description

  The present invention relates to a printing layer structure for base material transfer. Printing of a design is completed at once, and it is transferred to the base material so that printing does not take time and wear resistance is good. The print structure is beautiful and vivid.

  1 and 2 are a known printed structure manufacturing process instruction diagram and a printed structure sectional instruction diagram. In general printing of a skin material, a finished plate film is mainly used on the skin material or the base material 10a, and the design 11a on the plate film is printed one layer on the skin material or the base material 10a. Different designs, patterns and colors require different designs, patterns and colors. After printing on the skin or base material 10a by this layer printing method, the protective layer 12a is applied to the surface of the skin material or base material on which the design, pattern, or color is printed so that the design, pattern, or color does not fall off. To do.

  However, this type of printing once at a time is not satisfactory for the finished printing, and it is necessary to make a plate film. If the design changes, another plate film must be made. More than one plate is required at a time. Furthermore, since the plate film is not easy to transport and is printed by human hands, the screen printing operation takes about three to six days, is not speedy, and is not economically efficient.

    The problem to be solved is that since the printed layer cannot be completed at once, the work efficiency is poor and the finish is not good.

  The present invention transfers a high-quality printed layer to a base material quickly. A TPU protective layer is bonded to the PET separate type film bottom layer, a resin layer is bonded to the TPU protective layer, and a PC inkjet is applied to the resin layer. To print colors, designs and patterns to form a print layer. Furthermore, when the printed layer is bonded to the substrate by thermal transfer and the PET separate type film bottom layer is peeled off, printing is completed, and the surface is characterized by forming a friction-resistant printing structure.

The substrate transfer printing layer structure of the present invention has the following advantages.
Ink printing is completed at once. A print layer is formed by applying a design, a pattern, and a color directly on the resin layer by a PC inkjet method. Therefore, the time and labor required for screen printing can be saved.
Work efficiency is improved. Necessary designs, patterns, and colors are applied by a PC inkjet method. An ink is applied on a resin layer to form a print layer, and then printed on a substrate by a thermal transfer method.
Wear resistance. When it is transferred to the substrate and the PET separate type film bottom layer is peeled off, the TPU protective layer appears on the surface. The resin layer and the printing layer are protected by the TPU protective layer, and printing is difficult to drop.
Has good adhesive properties. The TPU protective layer and the resin layer have thermoplastic and heat melting characteristics. Therefore, each layer has a good adhesive effect, and the resin layer has the property of absorbing ink, so that the ink on the printing layer is difficult to drop and the finishing effect of the printing layer is high.

As shown in FIGS. 3, 4, and 5, the present invention mainly transfers the printing layer 1 onto the substrate 2. The print layer 1 includes a PET separate type film bottom layer 10, a TPU protective layer 11, a resin layer 12, and a print layer 13. Among them, the PET separate type film bottom layer 10 is placed on the printing layer 10, and the printing layer 1 is thermally transferred to the substrate 2, peeled off from the printing layer 1 and separated. The TPU protective layer 11 is placed on the PET separate type film bottom layer 10 and forms the surface layer of the print layer 1 after the PET separate type film bottom layer 10 is peeled off. The resin layer 12 is disposed on the TPU protective layer 11 and has a property of being dissolved by heat. The print layer 13 is placed on the resin layer 12, and colors, designs, and patterns are applied by a PC ink jet to form the print layer 13. The printed layer 1 is printed on the substrate 2 by a thermal transfer method, and the PET separate type film bottom layer 10 is peeled off to form a printed layer on which the TPU protective layer 11 forms a surface layer.

  The TPU protective layer 11 has a thermoplastic property by the PET separate type film bottom layer 10 and is bonded to the PET separate type film bottom layer 10 by a heating method. At this time, the resin layer 12 is applied to the TPU protective layer, and the resin layer 12 also has a thermal transfer function, and a printed layer 13 having a design, pattern, and color necessary for the PC ink jet application method is formed on the resin layer 12. At this time, the resin layer 12 sucks ink on the print layer 13, and the ink of the print layer 13 is less likely to be decolored or dropped after being ejected by the PC inkjet method. Further, when the above-described steps are completed, the printing layer 1 is immediately formed, and the printing layer 1 is completely printed on the substrate 2 by the pressure thermal transfer method. The temperature at this time is about 120 degrees. As a result, a speedy and beautiful printed structure is completed on the substrate 2. The base material described in the present invention is a material such as a skin material, a spun product, plastic, and PU.

It is a manufacturing process instruction figure of a well-known printing structure. It is a well-known printed structure cross-section instruction drawing. FIG. 2 is a cross-sectional view of a printing structure according to the present invention. It is a printed structure manufacturing process instruction figure of this invention. It is a printing structure and substrate bonding instruction diagram of the present invention. It is a three-dimensional instruction diagram of the present invention.
