Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel, a manufacturing apparatus thereof, and a manufacturing method thereof.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel, a manufacturing apparatus thereof, and a manufacturing method thereof, and more particularly, to a decorative panel attached to a surface of an appliance, a sink, furniture, A decorative panel which has a pattern or a pattern formed by one design and which has excellent readability, a background effect of a soft feeling, and an excellent dimensional sensation, so that visual effect and value of the product can be enhanced, a manufacturing apparatus thereof and a manufacturing method thereof .

Generally, panels are made of wood and easy to work. They are applied to household appliances, study and office tables, book shelves, closet or furniture such as table or sink, and are used as interior materials of various buildings if necessary.

Conventional panels are manufactured by attaching a transfer sheet or a plastic sheet having a pattern of various colors on the surface thereof or by applying a paint coating on the surface many times so that the surface durability is enhanced and the unmeasurement is improved .

However, the adhesion method of attaching the transfer sheet or the plastic sheet to the surface of the panel by using the above-described tape lowers the flatness with respect to the surface of the panel to lower the quality of the product, or the defect rate to be squeezed when the tape is not correctly adhered is high There is a problem that the function of protecting the surface of the panel is not properly implemented.

In the case of coating the surface of the panel with the paint many times, the flatness of the surface of the panel is excellent as compared with the adhesion method described above, but the process of applying or coating the paint many times is very troublesome, There is a problem that pollution inducing factors are generated.

In addition, the paint coating method causes a variation in the process of applying and coating the paint a plurality of times, which causes the surface of the panel to be stained. In addition, the paint applied at the same time a plurality of times can penetrate the surface of the panel over time with the moisture contained in the paint, so that it can generate calm wavy spots on the surface of the panel partly. Therefore, a quality product can not be obtained in comparison with the laboriousness of workability, and there is a problem that the production period and the manufacturing cost are increased due to a decrease in productivity of the product.

Another method is to cut the panel surface to a predetermined pattern and a predetermined depth to primarily form the engraved pattern grooves. However, since the manufacturing process is too complicated, this method has a problem that the fabrication period is long and the manufacturing cost is greatly increased due to complicated patterns.

On the other hand, there is a decorative panel in which the adhesion method is partially improved, and a transfer sheet having a pattern formed on the back surface of the transparent panel material is attached. However, in this case, the pattern formed on the transfer paper is expressed only in two dimensions and the visual effect is limited by the initially set color or pattern, which causes the consumer to easily feel the proof.

Accordingly, some techniques for imparting a three-dimensional effect to the pattern formed on the decorative panel have been disclosed. However, the decorative panel providing the conventional three-dimensional pattern is not only insufficient to satisfy the expectation value of the user but also causes the stereoscopic effect to prevent the main pattern or the pattern to be displayed by the manufacturer from being displayed properly There is a problem that the readability of the designed pattern or pattern and the aesthetics of the whole product are lowered and the value of the product is lowered. Further, a product that maximizes the stereoscopic effect of a designed pattern formed by a printing unit having a multilayer structure has not been disclosed to date.
