Description

The present invention relates to a graphics display, and more particularly to a graphics display used for a sign, board, or panel illuminated after the marking.

Generally, graphics display bodies are used in various fields such as displays, advertisements, signs, labels or nameplates, stickers, and the like. For example, in the field of lighting signs and lighting advertisements, there are those illuminated by an artificial light source in front of the sign and those illuminated from behind the sign. The former is called external lighting and the latter is called internal lighting. In the case of internal illumination, the image of the graphics display provided on the surface of the sign is recognized through natural light in the daytime or a light source in the room, and the illumination light transmitted from the back surface of the graphics display at night or in a dark room. I am aware of it through.

As a conventional graphic display body, for example, there is one described in Patent Document 1. In this method, an organosol of a vinyl chloride resin is applied and dried on the surface of a PET film that has been peeled off to form a transparent film layer, an image layer is printed on the transparent film layer, and the transparent film layer and the image layer are preliminarily printed. It was produced by laminating a cut adhesive layer (see Patent Document 1). This conventional graphics display has been used by being adhesively attached to a base material such as a transparent vinyl chloride flexible sheet via the adhesive layer.

Japanese Patent No. 5749456

However, in the manufacturing process of a conventional graphics display, (1) a transparent film layer forming step, (2) an image layer printing step, (3) an adhesive layer laminating step, and (4) a base material are used. It was necessary to go through a plurality of manufacturing processes including a sticking step to the coating, and the manufacturing cost may be high.

In addition, when it is used, it has to be adhered and attached to the base material manually, which is a troublesome work. This work had to be attached so as not to allow air to enter between the base material, and there was also a problem in handleability. For this reason, skill is required for the pasting work, which may increase the cost. There is also a problem that the adhesive strength is weakened when air is present between the base material and the base material.

Further, since the conventional graphics display is a laminated film structure in which a base material and a transparent film layer are adhered to each other, a film fee and a laminating fee are required as compared with a single-layer structure, which is related to material cost. The cost cost was also high.

As described above, the conventional graphics display has problems in terms of workability, handleability, economy, or productivity.

Therefore, an object of the present invention is to provide a graphics display body capable of improving workability, handleability, economy, or productivity.

The present invention is not limited to the following embodiments.
(First Embodiment)

The graphics display 100 of the present embodiment is internally illuminated, for sign graphics applications such as lighting signs, lighting advertisements, posters, panels, banners, bus / train wrapping, window films, price lists, direction indicator boards, etc. It is used for various display board applications.

In particular, the graphics display 100 is suitable for use in facilities having a non-dark room and a dark room environment, such as a movie theater, a concert venue, a live house, a planetarium, a public facility, and a school building, and is suitable for use under a light source and in the dark. Can give different visual sensations.

As shown in FIG. 1, the graphics display body 100 is formed by laminating and printing a plurality of printing layers 20 to 50 on a flat substrate 10 in this order. The print layers 20 to 50 are UV ink layers in which UV ink is cured, and are formed on the flat substrate 10 so as to have a thickness in the range of 35 μm to 250 μm.

The flat substrate 10 is not transparent, but has translucency. Transparency refers to the property of allowing light to pass through, having extremely high transmittance, and allowing the other side to be seen through a substance. The extremely high transmittance means that the light transmittance is 80% or more in visible light, that is, in the wavelength range of 380 nm to 780 nm.

Examples of the flat base material 10 include a translucent flat film, a translucent flat sheet, and a translucent flexible sheet. A translucent flexible sheet is preferable in terms of flexibility and weather resistance. The flat substrate 10 preferably has a light transmittance in the range of about 20 to 35%. The method for measuring light transmission is based on JIS K 7105. Further, it is more preferable if it is excellent in waterproofness, flameproofness, stain resistance, and printability.

The flat base material 10 of the present embodiment is composed of a flexible sheet having a thickness of 400 μm to 800 μm. This flexible sheet has a light transmittance of about 33% and is about 1.5 times brighter than the conventional flexible sheet. In addition to this high transparency, the flat substrate 10 has a characteristic that the image of the illumination light is difficult to see and the threads are invisible. It has air resistance and excellent weather resistance. Of course, because it is light and has excellent flexibility, it can be installed at low temperatures.

The printing layers 20 to 50 of the present embodiment have a multilayer printing laminated structure provided on a single-layer flat substrate by inkjet printing using UV ink, and are a first display printing layer 20 and a shielding printing layer 30. The light-restricted print layer 40 and the second display print layer 50 are included. Of these, the light-restricted print layer 40 has a plurality of openings 44, and the second display print layer 50 has a plurality of openings 52. That is, the graphics display 100 of the present embodiment has a plurality of bottomed openings that open in the opening direction with the shielding printing layer 30 as the bottom in the printing layers 20 to 50, and the light limiting printing layer 40 and the second. The display print layer 50 is composed of non-openings 43, 51 having openings 44, 52.

The first display print layer 20 is a non-perforated UV ink layer having no openings. The first display print layer 20 may be a print layer in which UV ink is cured, and the color, type, etc. of the UV ink are not particularly limited, and various types can be used. The first display print layer 20 has a first design 23 applied with UV ink. The first design 23 may be multicolored or single-colored, or may be black-and-white, monochrome, or other colors only. Of course, the first design 23 may be full color.

The first display printing layer 20 of the present embodiment includes an undercoat layer 21 and a topcoat layer 22. The undercoat layer 21 is printed on the entire surface of the flat substrate 10, and the topcoat layer 22 is printed on the entire surface of the undercoat layer 21. In the present embodiment, the topcoat layer 22 and the undercoat layer 21 are each provided with the same design, and since this is written twice, the first display print layer 20 has the first design 23. Specifically, the first display printing layer 20 is a UV ink layer having a flat laminated structure, and the first design 23 is composed of a full-color landscape photograph applied to substantially the entire surface thereof and characters held in the center thereof. Become.

The shielding printing layer 30 is a UV ink layer provided between the first display printing layer 20 and the light limiting printing layer 40, contains black or dark UV ink, and is represented in black or dark. The shielding printing layer 30 of the present embodiment is a non-perforated single-layer structure in which dark UV ink is solid-printed on the entire surface of the topcoat layer 22 by inkjet printing, and the UV ink is cured. Examples of the method for expressing the dark color of the shielding printing layer 30 include an inkjet printing method using dark blue, dark brown, indigo, purple, and other dark UV inks. The shielding print layer 30 may be recognized as black when irradiated with visible light or infrared light, and does not necessarily have to be represented by a density of 100% black ink K. The shielding printing layer 30 exerts a function of shielding the second design 53 included in the second display printing layer 50 at the time of internal illumination.

The light-restricted printing layer 40 has a non-opening 43 and a plurality of openings 44. The light-restricted printing layer 40 has a large number of small circular openings 44 that are regularly arranged vertically and horizontally with UV ink on the entire surface of the shielding printing layer 30, and has a non-opening 43 having a portion other than the openings 44 as the ground. It is a porous UV ink layer in which UV ink is cured by inkjet printing.

Further, the light-restricted printing layer 40 has a two-layer printing laminated structure including a dark-colored perforated printing layer 41 and a white-based perforated printing layer 42 in a vertical cross-sectional view. The opening 44 is formed in each of the dark-colored perforated printing layer 41 and the white-based perforated printing layer 42 at the same position, coaxially, and with the same hole diameter.

Here, the same position means that there is no deviation in the point, linear shape, or planar shape from the theoretically accurate position defined in the datum or other shape of the print data, or within the permissible range. The hole diameter refers to the maximum size of the opening 44 regardless of the shape of the opening 44 when observed from the opening direction of the opening 44.

The dark-colored perforated printing layer 41 is a UV ink layer printed on the entire surface of the shielding printing layer 30, contains black or dark-colored UV ink, and is expressed as black or dark as a whole. The dark-colored perforated printing layer 41 exerts a function of shielding the first design 23. Examples of the method for expressing black or dark color of the dark-colored perforated printing layer 41 include smear, rich black, and four-color solid in CMYK colors. Sumibeta is expressed with a density of 100% black ink K. Rich black is created by multiplying the colors of CMYK. The four-color solid is created with 100% of each CMYK color.

The white perforated printing layer 42 is a UV ink layer provided between the dark color perforated printing layer 41 and the second display printing layer 50, contains white UV ink, and is expressed in white. .. The density of the white UV ink is preferably 100%. The white-based perforated printing layer 42 and the dark-colored perforated printing layer 41 contain different UV inks, but their shapes and structures may be the same. The white perforated printing layer 42 exerts the function of undercoating the second display printing layer 50. It is also called whitening.

The second display print layer 50 is a single-layer UV ink layer that constitutes the surface of the graphics display body 100. The UV ink contained in the second display printing layer 50 is not particularly limited, and various inks such as full color can be used. The second display printing layer 50 has an opening 52 having the same position, coaxiality, and the same hole diameter as the opening 44 on the entire surface of the light limiting printing layer 40. The second display printing layer 50 is a perforated UV ink layer in which the UV ink is cured by inkjet printing the non-opening 51 with UV ink on the entire surface of the non-opening 43, and the second design 53 is formed. Have.

The second design 53 may be multicolored or single color, or may be black and white, monochrome, or other colors only. Of course, it may be full color. The second design 53 may be the same as the first design 23, but is preferably different. The second design 53 of the present embodiment includes characters of a single color printed with UV ink and a background of a color different from the characters.

Next, a method of manufacturing the graphics display body 100 will be described. The print layers 20 to 50 are sequentially printed on the flat substrate 10 by inkjet printing using UV ink. Here, in order to print the light-restricted printing layer 40 and the second display printing layer 50 having the respective openings 44 and 52, a predetermined aperture ratio parameter may be set in advance and stored. The aperture ratio is a percentage of the area where the shielding printing layer 30 or the first display printing layer 20 is exposed when observed from the opening directions of the openings 44 and 52 per unit area of the graphics display body 100. Represented.

First, in each print data of the dark color perforated printing layer 41, the white perforated printing layer 42, and the second display printing layer 50, the position, size, and interval of the opening path are set. At the same time, print data of other print layers 21, 22, and 30 are prepared and saved.

Then, using the saved print data, the computer sequentially prints out the UV inkjet printer. With this, the graphics display body 100 of the present embodiment can be obtained. That is, the first display printing layer 20 having the first design 23 and the shielding printing layer 30 are printed, and the openings 44 and 52 are not printed, and the other portions, the non-openings 43, 51 and the first. The graphics display 100 is completed by printing the second design 53 and providing the laminated printing layer on which the light limiting printing layer 40 and the second display printing layer 50 are formed on the single-layer flat substrate 10.

The aperture ratio of the openings 44 and 52 originally depends on the size and dimensions of the graphic display body 100, but in general, when observed from the opening direction of the openings 44 and 52, the second design 53 is used. It is preferable that the first design 23 is set within a range in which both non-internal lighting and internal lighting can be comfortably viewed. For example, in the case of the graphics display 100 having a predetermined number of openings 44, 52 per 100 square mm, the aperture ratio is preferably in the range of 28% to 47%, preferably 30% to 45%. More preferably, the aperture ratio is about 38%.

If the aperture ratio is less than 30%, it is difficult to manufacture, and the graphics display 100 becomes dark and difficult to see when illuminated internally. Further, when the aperture ratio exceeds 45%, the concealment ratio decreases, and the first design 23 becomes visible through the openings 44 and 52 during normal non-internal illumination.

The pore diameters of the openings 44 and 52 are preferably in the range of 1,600 μm to 2,000 μm. When the hole diameters of the openings 44 and 52 are less than 1,600 μm, it becomes difficult to see them during internal illumination. Further, when the hole diameters of the openings 44 and 52 exceed 2,000 μm, the first design 23 and the second design 53 are confused at the time of non-internal illumination, and it becomes difficult to distinguish them.

As described above, in the graphics display body 100 of the present embodiment, as shown in FIG. 2, a second display printing layer 50 having the second design 53 is formed on the surface side of the graphics display body 100. .. When the graphic display body 100 is viewed from a distance in the non-internal illumination, the second design 53 on the second display print layer 50 and the other background are visually recognized.

As shown in FIG. 3, the graphic display body 100 has a pattern in which a dot-shaped hole that cannot be identified when viewed from a distance is formed when viewed from the vicinity or the vicinity when not illuminated. It is visually recognized. This is due to a plurality of circular openings 52 which are regularly held vertically and horizontally in the non-opening 51 of the second display printing layer 50, not through the through holes.

The plurality of openings 52 are arranged vertically and horizontally, for example, per 100 square mm, and the plurality of openings 52 arranged in any one row in the longitudinal direction and the other closest to the row. The plurality of openings 52 arranged in the row of the above are staggered so that the positions of the center points are substantially zigzag. Further, in the graphics display body 100, a plurality of bottomed semi-cylindrical openings are arranged on one side side surface of the second display printing layer 50.

(Observation of usage conditions)
A graphics display 100 was obtained by using a UV inkjet printer manufactured by Lucio Co., Ltd., model name: LDP3200, and using a UV ink for this printer. The graphics display body 100 was stretched and provided in front of a lighting advertisement illuminated after the signboard to obtain a wall-mounted signboard. The second display printing layer 50 was hung on the wall of the movie theater with the front side as the front side, and the usage state was observed.

Next, when the light source in the movie theater was turned off and the room was illuminated internally, the room became completely dark and the second design 53 was completely invisible. At the position where the second design 53 was visible, as shown in FIG. 4, a full-color landscape photograph of the first design 23 in the darkness and a substantially center so as to emerge against the background of the landscape photograph. The letters "U", "V", "W", "X", "Y", and "Z" appeared in white and with high brightness.

As described above, according to the graphics display body 100 of the present embodiment, for example, under a light source, it can be recognized as various displays such as a signboard, an advertisement, a signboard, and a guide board, and in the dark, the various displays under the light source are. It is possible to display lighting advertisements and lighting signs such as different advertisements, messages, and images. Suitable for wall-mounted signboards.

Further, according to the graphics display 100 of the present embodiment, since the above configuration is used, the second design 53 can be recognized via the light source in the room, and in the dark without a light source, from the back surface of the graphics display 100. The first design 23 can be recognized through the transmitted illumination light. Although the first design 23 is different from the second design 53, it is not interfered with by the second design 53 and has a high degree of freedom in selecting both designs. That is, both designs are not necessarily limited to the range of the same system color, and combinations having different color systems can be selected.

Further, according to the graphic display body 100, it is possible to express white color when internally illuminated in the dark. According to the graphic display body 100 of the present embodiment, when the image is illuminated in the dark, the character of a single color, which is the second design 53, and the background of a color different from this are not visually recognized at all, and the first White characters appear on the front of the landscape photograph of the full-color background, which is the first design 23, and the first design 23 and the second design 53 can be visually recognized without being confused.

In addition, the ink can be printed directly on non-absorbent media, and volatile harmful compounds (VOCs), which are a problem with solvent-based inks, are not generated, which is environmentally friendly.

Further, according to the graphic display body 100 of the present embodiment, since the aperture ratios of the openings 44 and 52 are 30 to 45%, it is not too dark and not too bright, and is not too dark and not too bright. The displayed contents can be comfortably visually recognized in any case of internal lighting.

Further, according to the graphic display body 100 of the present embodiment, since the white perforated printing layer 42 is provided, the second design 53 can be accurately expressed. That is, since the UV ink is transparent, if the step of forming the white perforated printing layer 42 is omitted, the color of the second design 53 is formed in the printing step of the dark color perforated printing layer 41 in the previous step. It mixes with black or dark colors and causes color mixing. On the other hand, according to the graphic display body 100 of the present embodiment, since the white perforated printing layer 42 is provided, this can be prevented.
