Description

Detailed Description of the Invention

  The present invention is intended for decoration of various plastic molded products such as injection-molded members, and a layer having an image or color is formed in a thin film on the surface of a member such as an injection-molded product. The present invention relates to a technique for imparting decoration to a member such as an injection-molded product, and a decoration manufacturing method for manufacturing the decoration. The present invention relates to the decoration, and is characterized in that an image is formed using various printing techniques and the image is transferred by hydraulic transfer. In particular, if an inkjet technique is used as an image forming technique, an image formed on demand using inkjet printing can be transferred and formed as a decoration or the like. This hydraulic transfer imaging technology and system can be applied to a wide range of decorative and decorative imaging.

  The hydraulic transfer technique is a technique for transferring an image film mass-produced by using an image forming technique such as printing to a member such as various molded articles using a hydraulic pressure with a uniform pressure. Many of the hydraulic transfer processes involve forming various images on a water-soluble substrate film using a printing technique such as a gravure printing technique, and transferring the formed image onto various member surfaces by hydraulic transfer. .

  The hydraulic transfer process is applied to many plastic molded products. For example, it is used for decorating frame forming members such as various instrument panels of motorcycles such as dashboards of dashboards, instrument panels and console boxes.

  Conventionally, a method for forming an image on a hydraulic transfer film by offset printing, letterpress printing, screen printing, gravure printing, or the like is used to manufacture the hydraulic transfer sheet. For example, in Patent Document 1, a film for water pressure transfer is floated on the water surface with the image forming surface facing up, and then various molded bodies as a material to be transferred are pushed in from above, thereby transferring the material using water pressure. A method is described in which the printed layer is transferred to the surface of the body. This method is not considered to be suitable for small-lot production that meets the demand for small-lot, multi-product production.

  In recent years, many products are required to have not only basic functions but also many decorative properties. One of the major reasons is that it is difficult to differentiate due to inherent characteristics and performance of products. In recent years, when the inherent performance is uniform, important values are demanded for decoration such as decoration and appearance design.

  As a result of advanced development of mass production technology that was the ultimate in industrial technology for various products, similar products came to be supplied in large quantities. If there is a bottleneck in the supply of various products, a large demand is expected compared to the supply, so it has been sold as produced. However, as a result of the great development of supply capacity, the situation of being sold as much as produced has changed greatly, and has reached the situation where it is produced as much as necessary for the quantity sold. In such an environment, in order to increase sales of individual business entities, it is necessary to promote differentiation from products of other companies.

  In order to differentiate the various products, advanced functions and prices can be considered. However, the sophistication of functions is difficult due to rapid commercialization, and the price is difficult due to globalization. Differentiating is personal customization. In other words, each customization is performed according to the personal experience and preference. For such ultimate customization, on-demand production based on individual demands can be considered. Patent Document 2 and Patent Document 3 are inventions related to a hydraulic transfer film corresponding to a small lot production.
