Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a printed matter that can obtain a colored pattern that looks like a metal plate is engraved (etching effect) in accordance with the metallic brightness. .

[Purpose of the invention]

For example, sheet-like printed materials such as label materials and painting materials that can have colored patterns with metallic brightness are formed by various methods. The combination of a pattern that looks as if the board has been carved (etching effect) and a colored pattern,
The objective is to provide printed matter with metallic brightness and beauty that cannot be obtained conventionally.

[Embodiments of the invention]

The present invention will be explained in detail below based on embodiments shown in the drawings.

FIG. 1 shows an enlarged cross section of a printed matter made according to the present invention, in which 1 is aluminum foil, 2
3 is an offset printing layer applied to the surface of the clear layer 2, and 4 is an offset printing layer 3 coated on the surface of the aluminum foil 1.
5 is a patterned screen printing layer applied to the surface of the top clear layer 4; 6 is the patterned screen printing layer 5;
These layers constitute the printed matter that is the object of the present invention.

Next, to describe the structure of each layer in detail, aluminum foil 1 has a thickness of, for example, 0.05 mm.
This aluminum foil 1, which has a circumference of about 0.1 mm, becomes the base sheet of the printed matter of this embodiment.

The clear layer 2 formed on the surface of the aluminum foil 1 is provided in order to substantially equalize the uneven reflectance that occurs on the surface of the aluminum foil 1.
This clear layer 2 suppresses the partially high-intensity reflected light on the aluminum foil 1 and averages the brightness, and furthermore, this clear layer 2 allows offset printing on the aluminum foil 1 to be performed. can be easily printed in the same way as printing on regular paper. Effective materials for the clear layer 2 include, for example, transparent acrylic resin and polyester resin, and these resins are coated to a uniform thickness of, for example, about 3 microns.

The offset printing layer 3 applied to the surface of the clear layer 2 is formed by coloring and printing an appropriate pattern, picture, or other design using transparent or translucent process ink.
As a result, a pattern with brightness is expressed due to the reflective action of the offset printing layer 3 and the aluminum foil serving as the base thereof.

The top clear layer 4 applied to the surface of the offset printing layer 3 is a UV clear applied by a well-known printing method, but there is a disadvantage in terms of cost in applying this offset printing layer 3.
Since this top clear layer 4 is not required as a product, the top clear layer 4 may be omitted.

Next, the patterned screen printing layer 5 applied to the surface of the offset printing layer 3 or the top coat layer 4 is the most important printing layer in the present invention. That is, this patterned screen printing layer 5 uses a transparent resin as a coating material and is applied by a well-known screen printing means, and this patterned screen printing layer 5 is formed in parallel in a plane as shown in FIGS. Diagonal lines, parallel horizontal lines, parallel vertical lines, concentric multiple circles, satin-like patterns, and the cross section is patterned to have, for example, fine triangular mountain-shaped unevenness in the shape of a Fresnel lens, and these various uneven patterns However, the offset printing layer 3
It is selectively formed to match the design of the. In other words, by selectively forming on the upper side of the offset printing layer 3 a concavo-convex pattern as shown in FIG. The brightness reflectivity changes depending on the viewing angle, and therefore the brightness of the design and the three-dimensional display effect are enhanced.

The surface of the patterned screen printing layer 5 is formed with fine triangular mountain-shaped irregularities, and a laminate layer 6 (protective layer) is provided as a means for maintaining the irregularities so as not to be damaged.

[Summary of the invention]

As described above, in the present invention, after forming a clear layer 2 of several microns on the surface of aluminum foil 1, an offset printing layer 3 is formed on the upper side of this clear layer 2 to display a pattern in an appropriate color, and then this A printed matter in which a patterned screen printing layer 5 is formed on the surface of the offset printing layer 3, in which a fine uneven pattern with a chevron-shaped cross section is formed in accordance with the above-mentioned design, and a laminate layer 6 is further provided on the surface of this patterned screen printing layer 5. be.

〔Effect of the invention〕

Therefore, according to this printed matter, the metallic brightness of the aluminum foil, the design applied to the surface of the aluminum foil, and the uneven pattern of the pattern screen printing layer formed to match the pattern of the design are threefold. Depending on the person, the brightness of a pattern with metallic brilliance changes depending on the angle at which the pattern is viewed. The printed matter is
Adoption of conventional printing means has the effect of commercializing products at low cost.

Claims (1)

[Claims] 1 After forming a clear layer 2 of several microns on the surface of the aluminum foil 1, an offset printing layer 3 is formed on the upper side of the clear layer 2 to display a pattern in an appropriate color.
Then, a patterned screen printing layer 5 is formed on the surface of this offset printing layer 3, in which a fine uneven pattern with a chevron-shaped cross section is formed in accordance with the above-mentioned design, and a laminate layer 6 is further formed on the surface of this patterned screen printing layer 5. A printed matter characterized by providing.
