Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative board patterned by surface printing, particularly by screen printing.

In recent years, decorative boards such as wood fiberboards, mineral fiberboards (rock wool boards, glass fiberboards), gypsum boards, pulp cement boards, calcium silicate boards, plywood, etc., have been decorated with surface printing, especially with a three-dimensional effect. Screen printing methods with excellent decorative properties have been widely adopted. However, when these decorative laminates are used for ceiling panels, walls, etc. of buildings, they tend to create unevenness at the boundaries between adjacent decorative laminates due to variations in thickness, which impairs the exterior appearance. , the side edges of decorative boards are often chamfered. That is,
After a screen-printed pattern 5' is formed on the substrate 3' as shown in Fig. 1, it is common to perform edge processing on both ends 13 as shown in Fig. 2, and the pattern is applied to the chamfered surface 2'. I couldn't do it. For this reason, the third
As shown in the figure, it is not possible to apply a continuous pattern to adjacent decorative boards, and the pattern is divided vertically and horizontally by the chamfered surface 2', which limits the design that can be expressed and reduces the decorative effect. It had

The present invention was made in order to eliminate the above-mentioned conventional drawbacks, and when the printed pattern is continuously printed from the surface of the board whose side edges are chamfered to the chamfered surface, the same It is provided so as to be continuous with the printed pattern of another substrate having a pattern, and this can be easily manufactured by screen printing or the like.

That is, the present invention will be explained with reference to the drawings, which are one embodiment. FIG. 4 shows a decorative board 1 according to the present invention, in which a screen printing pattern 5 continuous from the substrate surface 4 to the chamfered surface 2 is applied on a substrate 3 having a chamfered surface 2 on the side edge.

The decorative board 1 can be manufactured by, for example, a screen printer 6 shown in FIGS. 6 and 7. The screen printer 6 consists of a screen plate 7 and a cage 8. The screen plate 7 is a conventionally known one, in which a screen 10 having a desired pattern formed in the form of a mesh is stretched over a frame 9, and a screen plate 8 has a screen 10 formed in a cross-sectional shape of the substrate 3 at the contact portion with the substrate 3. It is a rubber-like body having concave portions 11 having approximately the same shape.

The decorative board 1 is formed by performing screen printing using the screen printer 6 in the same manner as the conventional method.

FIG. 8 shows the construction state of the decorative board 1.

As is clear from the above explanation, according to the present invention, since the printed pattern is provided on the chamfered surface, the joint pattern due to the appearance of the chamfered surface is not noticeable.
It has effects such as being able to express a beautiful continuous pattern with a high decorative effect that could not be expressed conventionally on a finished surface such as a ceiling surface.

Moreover, these can be obtained by screen printing without impairing the productivity of conventional printing.
