Description

[0001] DESCRIPTION [0002] Decoration sheets using gravure printing and methods of manufacturing the same [0003]

The present invention relates to a decoration sheet using gravure printing and a decoration sheet using the manufacturing method.

With the development of printing technology, various apparatuses and methods have been developed for coating a coating liquid on a coating material such as paper, synthetic resin film, or fabric.

Typical coating methods include Mayer Bar Coating method and gravure coating method, and a typical example of the gravure coating method is Doctor Chamber Type Gravure coating method.

The Meyer Bar Coating method uses a wire having a diameter of about 19 mm, and has a problem that scratches are frequently generated. The gravure coating method is preferred because it has less loss of coating solution and uniformity of coating as compared with other coating methods.

The gravure coating method is classified into a general gravure coating method (generally using a gravure roller having a diameter of 100 mm or more) and a micro gravure coating method (using a gravure roller having a diameter of 50 mm or less). The doctor chamber type gravure The method corresponds to a general gravure coating method.

Deco tiles are generally used as interior decorations for interior decorations. They are generally made of high-priced veneers. Deco tiles are made of relatively inexpensive synthetic resin panels as an alternative. Such a decorative tile is applied to products such as a desk, a dining table, a building interior material, a car interior, a frame, and the like, and is used as a substitute for a veneer to have the same or similar effect as a veneer.

In order to form a decorative tile made of such a synthetic resin panel, a printed thermal transfer film is transferred to the surface of a synthetic resin panel, which is a adherend, by a thermal transfer method to form a printed pattern on the panel surface to form a decor tile Respectively.

Therefore, in order to form such a transfer sheet, a transfer layer for the decorative layer is formed on the surface of the thermal transfer film, a printing layer is formed on the surface of the release layer, And then transferring the printed layer of the film to the surface of the adherend by thermal transfer to form a grain pattern on the surface of the adherend panel.

However, in the conventional transfer paper for a decorative tile, when the print layer is formed by simply printing a grain pattern, the texture of the print surface expressed on the surface of the panel, which is the adherend, is not the same as the pattern using the wood, It has the disadvantage that the quality of the decor tiles is deteriorated by being expressed as printed.
