Abstract

PURPOSE:To inexpensively form uniform and stable grain patterns in large quantities by printing dot patterns on one surface of a transparent substrate using white ink and apply the solid printing of black ink to the white dot patterns and printing dot patterns to the other surface of the transparent substrate using brilliant ink. CONSTITUTION:Dot patterns 12 are printed on the rear of a transparent substrate 10 using white ink and a solid printing surface is formed to the dot patterns 12 by printing so as to paint out said patterns 12. The solid printing surface 14 is pref. formed using black ink but white, gray or dark color ink is also used. Dot patterns due to brilliant ink are printed on the surface 10b of the transparent substrate 10. The same brilliant dot patterns 16 as the white dot patterns 12 on the rear are formed by silk screen printing and can be printed inexpensively in large quantities. The grain pattern sheet whose both surfaces are printed can form a grain pattern having a high grade feeling by the mutual action of the white dot patterns 12 and brilliant dot patterns 16 provided to both surfaces of the transparent substrate 10.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stone pattern printing method and a stone pattern sheet, particularly for printing a stone pattern on a lightweight thin film sheet used for the exterior of furniture, electrical appliances, etc. The present invention relates to a method and a stone-grained sheet.

[Prior Art] Various printed patterns are applied to the exterior of furniture or electrical appliances, wallpaper sheets for interior decoration, etc., and the desired luster or hue is obtained by printing, painting, plating, etc. .

However, in recent years, there has been a demand for a stone grain pattern with a solid feel on the exterior surface of such furniture or electrical appliances, and in the past, exterior sheets that resemble a stone grain pattern using plating or painting have been proposed. .

Conventionally, as shown in Japanese Patent Laid-Open No. 1-249173, for example, as shown in Japanese Patent Application Laid-Open No. 1-249173, a method of applying a finish coating similar to granite polishing has been put into practical use as a coating method for building boards.

[Problems to be Solved by the Invention] However, in the conventional stone grain pattern of this type, it is common to apply multiple layers of coating to a thick board, and it is difficult to create such a solid feeling on a lightweight thin sheet. It was almost impossible to create a pattern with a certain grain pattern.

In particular, it is essential to reduce the weight of the exterior of household electrical appliances, and there is a strong demand for creating a desired stone grain pattern using a plastic sheet as a substrate.

The present invention was made in view of the above-mentioned conventional problems, and its purpose is to form a uniform and stable stone grain pattern on a lightweight thin film substrate in large quantities at low cost, so that it can be widely used for the exterior of furniture or electrical appliances. An object of the present invention is to provide an improved stone pattern printing method and a stone pattern sheet.

[Means for Solving the Problems] In order to achieve the above object, the method of the present invention includes the steps of printing a mesh pattern of white ink on one surface of a transparent substrate, and printing a black ink solidly on the white mesh pattern. The method is characterized in that it includes a step of printing, and a step of printing a net pattern of glittering ink on the other surface of the transparent substrate.

Further, the stone pattern sheet according to the present invention has a white net pattern and a black solid printing surface overlaid thereon printed on one side of a transparent substrate, and a glitter net pattern printed on the other side. It is characterized by

[Operations] Therefore, according to the present invention, a gloss that cannot be obtained with conventional painting can be obtained, and in particular, the glitter net pattern formed on the sheet surface expresses different tones depending on the degree of light interference depending on the viewing angle. This makes it possible to obtain a variety of stone grain patterns.

According to the present invention, different net patterns are formed on both sides of the transparent substrate, and the combination of these two patterns has the advantage that a deep pebble pattern can be realized on a thin, lightweight sheet.

These lightweight thin film sheets can be used in a wide variety of fields because patterns can be formed on both sides of the sheet in large quantities and with stable quality by printing.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a procedure for printing a mesh pattern sheet according to the present invention.

Figure 1A shows a net pattern (12) of white ink on the negative side of the transparent substrate (10), and in the example, on the back side (10a).
FIG. 2 shows the process of printing and forming the white ink net pattern, and an example thereof is shown in an enlarged scale in FIG.

In the embodiment, the white ink is formed by silk screen printing, and as the ink itself, ordinary acrylic ink or any other ink can be used.

Further, the transparent substrate (10) is formed of an acrylic or polypropylene plastic sheet for boat fishing, but a glass plate or the like can be used if necessary.

FIG. 1B shows the white network pattern (
Step 12) is a step of forming a solid printing surface (14) which is printed so as to cover up the mesh pattern (12), and this solid printing surface (14) is preferably made of black ink. , white, gray or dark ink is used.

FIG. 1C shows the final printing process characteristic of the present invention, in which the other side of the transparent substrate (10), in the example, the front side (10
b) A mesh pattern is printed with glitter ink.

FIG. 3 shows an example of a net pattern made of this glitter ink, and in the present invention, of course, this pattern can have any shape.

The glittering ink is preferably, for example, rcOLOsERI FN/Glitter Screen Ink (trade name) sold by Jujo Kako Co., Ltd., which contains a glittering pigment,
A variety of tones are produced depending on the degree of light interference.

This glitter ink is selected in various colors as required, and depending on the angle from which the sheet is viewed, it may appear translucent gray, or it may reflect light and emit its original color.

Similar to the white net pattern (12) on the back side, the glitter net pattern (16) is also printed by silk screen printing in the embodiment, and can be printed in large quantities at low cost.

As described above, the stone grain pattern sheet printed on both sides as shown in FIG.
6), it is possible to form a high-quality stone grain pattern similar to the polished surface of a substitute stone.

In this sheet, the black and white color thread solid printing surface (14) forms the base of the sheet, and at this time, the side mesh pattern (12) provided on both sides of the transparent substrate (10) across the thickness thereof. , (16) has the effect of giving depth to the pattern, and can provide a deep color tone with a profound feeling even though it is a lightweight thin film sheet.

In particular, since the transparent substrate 10 has a certain thickness, the net pattern (12) is provided on both sides thereof.

The degree of overlap of (16) varies depending on the viewing angle,
Due to this change in overlap, even though it is a thin film sheet,
It is possible to create extremely deep patterns.

In the embodiments described above, the color tone of each net pattern and solid printing surface can be arbitrarily selected, whether achromatic or colored, and there are no restrictions on the type of ink or the type of transparent substrate.

[Effects of the Invention] As explained above, according to the present invention, it is possible to provide a stone grain pattern, which was previously impossible with thin film sheets, in large quantities at low cost, and it can be widely used for the exterior of electrical products, etc. There are advantages.
