Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile decoration method for decorating a tile surface by using a screen printing method. 2. Description of the Related Art In recent years, applications of the screen printing method have been expanded, and the screen printing method has been used for decoration of tile surfaces. For example, Japanese Patent Application Laid-Open No. 62-1821
In No. 77, not only the screen printing method is used but also a method for shading expression on a screen is devised. [0003] However, in the above-described conventional tile decoration method, paints screen-printed using a squeegee are only slightly painted (about 15 μm) uniformly on the tile surface. Absent. For this reason, although light and shade expression can be performed, light and shade expression of a light color tone can be performed only. [0004] Therefore, in order to enable not only light-colored colors but also shades of light, it is necessary to repeat screen printing several times to paint the paint thickly, which is complicated. Further, the screen position at the time of repeating the screen printing has to be matched with high accuracy. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and has as its object to easily expand the shade expression in tile decoration using a screen printing method. [0006] In order to achieve the above object, a procedure adopted by the present invention is a tile decoration method for decorating a tile surface using a screen printing method, wherein a screen is provided on the tile surface. A preparation step of setting, and a printing step of pressing a squeegee against the screen to move the screen to print the paint on the tile surface, and the printing step includes: It said while pressed against the screen
While moving the tile from one end to the other,
The trajectory of the squeegee moving on the screen meandering and skewed
Alternatively , the gist is that the process is a step of moving the squeegee so as to follow any of the zigzag trajectories and screen-printing the paint on the tile surface. In the tile decoration method having the above structure, a squeegee having a concave portion of a predetermined shape on an end face is moved while being pressed against a screen set on the tile surface to print a paint on the tile. One end of
The squeegee moves between the side and the other end.
Movement trajectory is meandering on the lean, of skew or jig Zag
Make one of the trajectories . In this way, the thickness of the paint is changed on the tile surface by changing the thickness of the paint according to the concave portion of the squeegee, and the change in the thickness of the paint according to the concave portion of the squeegee is changed by meandering, skew, or diagonal.
It appears on the tile surface along the movement trajectory of one of the zigzag squeegees. Therefore, it is possible to expand the shade of light through the change in the thickness of the paint painted on the tile surface, and change the thickness of the paint in accordance with the concave portion of the squeegee that brings about the shade of light, by meandering, skewing or zigzag.
On the tile surface along the trajectory of one of the squeegees. Next, a preferred embodiment of the tile decoration method according to the present invention will be described with reference to the drawings. First, the embodiment
A printing method which is a premise of the above will be described. FIG. 1 schematically shows the process. As shown in FIG. 1A, first, a tile 1
The screen 20 is set on the 0 surface. At this time, the screen 20 is set at a predetermined interval from the surface of the tile 10 as illustrated. The tile 10 includes a glaze layer 12 glazed on one side of a tile base 11, and the side of the glaze layer 12 is a decoration target surface (front surface). The screen 20 can be set so as to be in close contact with the surface of the tile 10. [0010] Next, as shown in FIG.
The squeegee 22 is pressed against the screen 20 at the outer position 10a at one end of the squeegee. Next, while pressing the squeegee 22 against the screen 20, the squeegee 22 is moved along the surface of the tile 10 as shown by an arrow c in the figure to a position 10b outside the other end of the tile 10. The squeegee 22 used at this time has three notches 23 on an end face 23 pressed against the screen 20, as shown in FIG.
a, 23b and 23c. Prior to the movement of the squeegee, the paint 30 is automatically or manually supplied from a paint supply device (not shown) to the screen 20 on the moving side of the squeegee 22.
Supplied on top. The movement of the squeegee 22 causes the paint 30 to move.
Passes through a printing pattern previously formed on the screen 20, and the surface of the tile 10
0 is screen printed. Since the print pattern of the paint 30 passes through the end face 23 of the squeegee 22, the amount of the paint 30 passing through the print pattern increases or decreases depending on the shape of the end face 23. That is, in the formation of the notches 23a to 23c of the end face 23, the paint enters the notches when the squeegee 22 moves, so that the extrusion amount of the paint 30 pushed out by each notch is limited to the range of the end face not having these notches. More than 23. Therefore, as shown in FIG.
In the print pattern range SL formed at 0, the paint 30 is painted as follows. That is, at the location where the notches 23a to 23c pass through the surface of the glaze layer 12 of the tile 10, the paint 30 has a convex shape and a thickness so as to fill each notch as shown in FIG. Remains. In addition, the paint 30 remains on the surface of the glaze layer 12 in the form of a film at the portion where the end face 23 passes without the notch. In this manner, the paint 30 is painted on the surface of the glaze layer 12 of the tile 10 in a state where the thickness of the paint is changed according to each notch of the squeegee 22. After the painting, the tile 10 is fired. As a result, according to the tile decorating method on which the present embodiment is based, it is possible to enlarge the shading expression in the tile decorating by changing the thickness of the paint 30 as shown in FIG. Moreover, in order to expand such a gradation expression, it is not necessary to use a special technique of screen printing or to repeat screen printing, and it is only necessary to provide a notch in a squeegee to be used. The shade expression can be easily expanded. Tile decoration method based on the above embodiment
In the method , the squeegee 22 is moved along the printing direction as shown in FIG. 1B, but in the embodiment according to the present invention,
As shown in FIG. 4, the squeegee 22 can be moved while meandering, moved diagonally, or moved zigzag. When the squeegee is moved in such a manner that the squeegee moving direction and the printing direction intersect, the paint 30 is left on the tile surface along the movement trajectory of the squeegee 22 as shown in FIG. And the decorativeness can be further improved. Although an embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and may be implemented in various modes without departing from the gist of the present invention. Of course. For example, the notch formed in the end surface 23 of the squeegee 22 may have any shape, size, etc., and may be rectangular or wavy. Further, since the squeegee 22 is tilted and moved in the traveling direction, the end face 23 of the squeegee 22 is used as in this embodiment.
Does not need to be formed from the front surface of the squeegee to the back surface thereof by cutting or the like, and may be performed as follows. That is, as shown in FIG. 5, the notch 23d may be formed so that the edge 23A of the end face 23 is cut obliquely. FIG. 5B is a view taken in the direction of the arrow X in FIG.
FIG. 5C is a view in the direction of the arrow Y in FIG. in this case,
As shown in FIG. 5 (A), the thickness of the paint has a notch 23 on the edge 23A of the end face 23 and the inclined squeegee 22.
The distance h from the upper end of d is determined. As described above in detail, according to the tile decoration method of the present invention, the thickness of the paint on the tile surface is changed in accordance with the concave portion of the squeegee. It is possible to enlarge the shade expression in decoration. Moreover, in order to expand such a gradation expression, it is not necessary to use a special technique of screen printing or to repeat screen printing, and it is only necessary to provide a notch in a squeegee to be used. The shade expression can be easily expanded.
Moreover, since the change in the thickness of the paint according to the concave portion of the squeegee is expressed on the tile surface along the moving trajectory of the squeegee, meandering, skew, or zigzag, a decorative pattern is added to the shading expression to enhance the decorativeness. It can be further improved. [0019] Also, in order to move the scan Chigi, meandering, it is a well simple and just to take one of the moving locus of the skew or zig-zag.
