Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing a stone patterned tile in which a pattern of metallic colors such as gold or silver is scattered.

(Background of the Invention) Conventionally, a pattern of a stone surface pattern is applied to the surface of a tile to give the tile a natural stone-like feel.

The object of the present invention is to manufacture a stone pattern tile with a scattered pattern of metallic colors such as gold or silver on the stone surface pattern. The manufacturing method is unknown.

(Summary of the Invention) The gist of the present invention is to separate the surface pattern of natural stone into multiple colors and prepare a screen printing plate with a pattern corresponding to each color by photolithography, Screen printing plates for metal colors with corresponding patterns are prepared separately using a sand grain contact screen, and multicolor screen printing using these printing plates is applied directly or indirectly to the tile surface to create a stone surface on the tile surface. The purpose is to form a pattern and a metallic-colored dot pattern.

(Function) That is, in the present invention, the color-specific patterns of black, gray, brown, etc. that make up the mottled pattern of natural stone are separated into each color by photolithography, and a screen printing plate with the corresponding pattern is created. For example, screen multicolor printing is performed on a transfer paper using a screen printing plate, while a screen printing plate with a corresponding pattern is made from a sand-grain contact screen as a special halftone printing plate, and a scattered pattern such as gold is printed on the transfer paper. The pattern on the transfer paper is then transferred to the surface of the tile by screen printing to form a stone surface pattern with scattered gold or other dots on the surface of the tile.

Alternatively, the above-mentioned black, gray, etc. colored patterns can be directly screen printed on the tile surface, and then a gold color etc. can be directly printed on it using a screen printing plate obtained from a sand grain contact screen. Forms a patterned stone pattern.

The pattern on the tile surface obtained in this way is
The effect of metallic colors such as gold and silver appearing in scattered spots creates a beautiful pattern. Moreover, this metallic pattern is created using an artificially created sand-grain contact screen, compared to the black, gray, brown, etc. that make up the stone surface pattern, which are printed on the tile surface using a photographic method. Because of this, the golden pattern is placed in a pattern that is different from the mottled pattern of natural stone, creating an effect that makes it stand out from the mottled pattern.

(Example) Next, in order to make the present invention more clear, examples thereof will be described below.

FIGS. 2A and 3 show stone patterned tiles manufactured according to an embodiment of the present invention,
As shown in the figure, a natural stone mottled pattern consisting of 14 black, 16 gray, and 18 brown patterns is displayed on the surface of the glaze 12 on the surface of the base 10, and furthermore, 22 gold patterns are scattered on top of it. I'm being ignored. FIG. 2B shows a state in which the gold pattern 22 stands out from the other patterns.

This stone pattern tile 24 was manufactured as follows.

First, as shown in Figure 1, a raw stone (natural stone) is photographed separately in black, gray, and brown colors, and transparent positive films 28, 30, and 32 with patterns corresponding to each pattern are prepared. , and these were used as mask materials and baked to produce screen printing plates 34, 36, and 38, respectively.

Separately, a screen printing plate 42 with a corresponding pattern was made in the same manner from a sand-grained contact screen 40 commercially available as a special halftone plate, and this was used as a plate for gold printing.

Next, using the screen printing plates 34 to 38, screen printing 44 of black, gray, and brown paints is performed on the transfer paper 46 for slide transfer, and then the printing plate 42 obtained from the sand-grain contact screen 40 is applied. A gold screen print 44 was applied on the same transfer paper 46 using the same transfer paper 46. The paint used here consists of a basic glaze and specified pigments, and is commonly used when printing on ceramics.

After each color pattern is screen printed on the transfer paper 46, a yellow resin layer is cover-coated on this paper, and this is immersed in water to swell and peel off the paper, resulting in the paint printed on the paper. was transferred to the resin layer.

On the other hand, prior to this, a tile having a glaze 12 on the surface is prepared by performing glazing 50 and final firing 52 on the tile base 48, and then a resin layer obtained by the above operation is applied to the surface of this tile using water. The pattern on the resin layer was transferred 54 by pasting the resin layer, and after drying, baking 56 was performed at a temperature of 800 to 850°C. At this time, the resin layer is decomposed and volatilized by heat, leaving only the paint on the tile surface, and the base glaze of the paint melts and becomes integrated with the glaze on the tile surface. As a result, the mottled pattern of natural stone is printed onto the tile surface, and at the same time, the gold color 22 is sprinkled thereon, resulting in the stone surface pattern tile 24 shown in FIGS. 2 and 3.

Although the embodiments of the present invention have been described in detail above, the present invention can also be implemented in other embodiments.

For example, as shown in FIG. 4, patterns in different colors such as black 14, gray 16, and brown 18 are directly screen printed on the tile base 10, or the patterns transferred onto transfer paper by screen printing are printed on the surface of the tile base 10. After transferring and printing a transparent glaze 58 thereon and firing it, the gold color 22 is directly screen printed on the glaze 58 using the screen printing plate 42 obtained from the sand grain contact screen 40,
Alternatively, indirect screen printing using transfer paper is also possible. In this case, the golden 22 dot pattern appears to stand out a certain distance from the mottled pattern forming the stone pattern, giving the pattern a sense of depth.

In addition, in the present invention, silver or other metallic colors may be used instead of gold, and other transfer methods may also be used. Furthermore, in the above example, the stone pattern and the golden pattern are transferred onto the tile surface using the same transfer paper, but the stone pattern and the golden pattern are screen printed on separate transfer papers. By transferring the patterns on the two types of transfer paper onto the tile surface, it is also possible to form a stone surface pattern with a golden dot pattern.
Furthermore, it is also possible to transfer the colors such as black, gray, and brown that make up the mottled pattern of the stone pattern onto separate transfer papers, and then use these transfer papers to form the mottled pattern on the tile surface. However, in addition to this, it is also possible to form multiple types of metal colors such as gold and silver on the tile surface, and the present invention can be implemented with various modifications without departing from the spirit thereof. It is possible to do so.

(Effects of the Invention) As detailed above, the present invention uses a photo printing method and a screen printing method to form a stone surface pattern on a tile surface, and at the same time, it is possible to form a stone surface pattern on a tile surface by using a photo printing method and a screen printing method. A natural pattern is one in which different patterns of metal colors are scattered on the tile surface.

As a result, it is possible to obtain a stone patterned tile with an outstanding metallic color and excellent aesthetic effect.
