[Effects of Invention]

The printing substrate of the present invention forms a pseudo three-dimensional printed image with a line count of 100 lpi or more and/or a resolution of 300 dpi or more, which can reproduce the original three-dimensional effect of the three-dimensional scanning object finely and vividly with high precision. (Curved surface) a printing substrate with a real three-dimensional impression of highly decorative printed images. In addition, with the pseudo three-dimensional printed image, irregular shape processing or the like is used to form concavities and convexities on the substrate, thereby not only visually but also by tactile perception of three-dimensionality, so that the viewer can be given a three-dimensional sense that is higher than the actual surface concavities and convexities.

In the manufacturing method of the printing substrate of the present invention, the printing data is made by a combination of scan data completed by a three-dimensional scanner or a combination of scanned data completed by a three-dimensional scanner and data completed by a non-three-dimensional scanner, etc. Combine most of the data to make printed data, or apply various corrections to the scanned data to make printed data, thereby improving the reproducibility of the 3D scanned object of the pseudo 3D printed image. Therefore, it can not only give the real three-dimensional effect, but also give more Emphasize three-dimensionality or decoration.

(Printing substrate) In the printing substrate of the present invention, the printed image formed on the substrate is a pseudo three-dimensional printed image based on the scanned data completed by the three-dimensional scanner, and the important feature is that the pseudo three-dimensional printed image is more than 100lpi and/or parsed. High-definition printing images with a degree of 300dpi or more are formed.

[Print image] In the printing substrate of the present invention, the pseudo three-dimensional printed image is printed based on the data obtained from the three-dimensional scanned object using a three-dimensional scanner, and it is important that the number of screen lines is more than 100lpi and/or the resolution is more than 300dpi, and the screen The number of lines is preferably 120lpi or more and more preferably 150lpi or more, and the resolution is preferably 600dpi or more. If the number of screen lines or the resolution is smaller than the above range, it is difficult to fully express the three-dimensional sense of the three-dimensional scanning object. In addition, the greater the number of screen lines and the resolution, the more high-definition printed images can be formed. In addition, when printing on non-ink-absorbent printing substrates such as metal substrates or plastic substrates, if the number of screen lines and resolution are too large, the dots may collapse. Therefore, it is best to set it below 300lpi or 1200dpi Within the following range.

Pseudo-three-dimensional printed images can be printed by conventional printing methods, as long as the above-mentioned number of screen lines and/or resolution can be formed, but ideally, it is best to print with a screen line number of 100lpi or more by non-horizontal printing. It is better to print images with a resolution of 300dpi or higher by inkjet printing. The pseudo 3D printed image can be formed by a variety of printing methods. At this time, all the printed images printed by multiple printing methods can meet the above-mentioned range of screen lines or resolution, or only a part of the printed image meets the above-mentioned range of screen lines Or resolution. The pseudo three-dimensional printed image can be formed entirely or partially on the substrate or combined with a flat general printed image.

In addition, as described later, the pseudo three-dimensional printed image is preferably based on: printed data formed by combining a large number of scanned data obtained from a large number of three-dimensional scanned objects; or combining one or more three-dimensional scanned data with one or more non- The printed image is printed from the data formed by three-dimensional scanning. With this, it is possible to combine materials or pseudo three-dimensional printed images with different concavities and convexities, so that a printed image with excellent design can be formed. But it is not limited to this, for example, by using the part of the shadow from the data obtained by scanning a matte substrate with unevenness, and using the part of the light from the data obtained by scanning a glossy substrate with unevenness, Then, the shadow part and the light part are combined to form the printed data, which can highlight the light and shadow on the pseudo three-dimensional printed image, so that a more three-dimensional pseudo three-dimensional printed image can be obtained. In addition, by changing the light irradiation direction relative to the three-dimensional scanning object and combining most data from different illumination angles, a pseudo three-dimensional printed image can also be formed. For example, most of the data scanned in the state where the light is irradiated in the relative direction of the three-dimensional scanning object, the brightest part of the light and the darkest part of the shadow are captured and combined, so that the emphasized shadow can be obtained. It is a more three-dimensional pseudo three-dimensional printed image.

FIG. 1 is a diagram for explaining a printed image that combines two scan data obtained by changing the irradiation conditions to form a three-dimensional pattern formed by concavities and convexities. In addition, in Fig. 1 (A) and (B), the right figure is a partial enlarged figure of the left figure. The scanned data shown in Fig. 1(A) makes a part of the image flat and blank under the influence of illumination, so the overall three-dimensional feeling is not impaired. Figure 1(B) is an image printed by synthesizing the blank part of (A) in the scanned data obtained by changing the lighting conditions of the same three-dimensional scanning object into the printed data in the blank part of (A) . It can be understood that Fig. 1(B) emphasizes the overall concavity and convexity, so compared to the image of Fig. 1(A), the three-dimensional perception is significantly improved.

In addition, in addition to the above-mentioned pseudo 3D printed images, the printed images can also be combined with printed images used to display information such as product descriptions, manufacturing year, month and day, or two-dimensional codes, but from the viewpoint of not impairing the design of the 3D printed image, The printed image for displaying information is preferably formed in the non-printed area of the pseudo three-dimensional printed image. In addition, the printed image for displaying information is preferably printed by a printing method different from the pseudo three-dimensional printed image in order to highlight their characteristics.

From the standpoint of vividly reproducing images with a three-dimensional effect, pseudo-three-dimensional printed images are best reproduced by using inks with four colors (yellow, purple, indigo, black) or more, and by using features as needed, The performance is more refined printing reproduction. In addition, the use of general printing inks can also form high-precision reproduction of surface unevenness and other three-dimensional printed images, but by using foam ink containing thermally expandable microcapsules in the printing ink for printing or by inkjet printing Formed by hot melt printing or tactile printing, it can have a high-design printed image that emphasizes the three-dimensional effect.

[Substrate] In the printing substrate of the present invention, the substrate forming the pseudo three-dimensional printed image can be used without limitation as long as it is a printable substrate. Although not limited to this, it can be metal substrates such as metal plates or metal containers; plastic substrates such as bottles, sheets, tubes, labels, films, bags, etc.; or paper or glass. Specifically, for example, surface-treated steel plates such as aluminum plates, aluminum alloy plates, and non-tin steels, lead-tin plated steel plates, chromium-plated steel plates, aluminum-plated steel plates, and plated steel plates are processed by drawing processing, drawing reduction processing, and re-drawing processing. Various metal cans such as seamless cans and welded cans formed from various metal plates such as nickel steel plates, tin-plated nickel steel plates, and various alloy steel plates; and polyester bottles formed from polyethylene terephthalate, etc.; and Olefin bottles made of polypropylene or polyethylene, etc. In addition, resin films such as polyester film, nylon film, polypropylene film, etc. may be laminated on the surface of the metal can. In addition, when a cylindrical container such as a metal can is used as a substrate for printing, it is better to form a pseudo three-dimensional printed image in an area that is more than 10% of the projected area of the front (side) of the container. When viewed from the front (side), less than 10% of the area may not be able to fully visually confirm the excellent three-dimensional effect of the pseudo three-dimensional printed image.

In addition, packaging bags (bags) and packaging labels (printed labels) can include, for example, resin films used in conventional packaging containers such as polyester film, nylon film, polypropylene, etc.; the resin film and heat-sealable resin or aluminum foil Laminates made of metal films such as; Laminates made of resin films and paper; or heat-shrinkable labels for plastic bottles made of polyethylene terephthalate, etc.

[Surface layer] In the printing substrate of the present invention, in order to faithfully reproduce the characteristics of the surface morphology of the three-dimensional scanning object on the pseudo three-dimensional printed image, a glossy layer or a diffuse reflection layer may be formed as the outermost layer.

The gloss layer is usually also called a varnish layer or a top coat, and is formed to protect the printed layer or make it shine. The varnish used to form the varnish layer uses a transparent thermosetting resin. For example, thermosetting polyester resins, acrylic resins, epoxy resins, etc. can be ideally used as thermosetting resin components and contain heat per 100 parts by weight. The curable resin component is formed by phenol resin, amine resin such as melamine resin, or isocyanate resin in an amount of about 0.1 to 10 parts by weight as the hardener component, and is formed by appropriately dissolving the resin component in an organic solvent use. It can also be mixed with lubricant ingredients such as paraffin wax and silicone oil in the varnish.

In addition, the diffuse reflection layer can be made of various materials that form fine irregularities on the surface and reduce the surface gloss of the printing substrate as much as possible, but in the present invention, it is preferably formed of a transparent matte varnish layer or matte film. By forming the diffuse reflection layer, the printed image can be clearly visually confirmed and the light entering the printed image can be diffusely reflected to eliminate the gloss, so it can be visually confirmed without damaging the three-dimensional effect of the printed image, such as surface irregularities or texture. . In particular, when using a substrate with surface gloss such as a metal substrate or a resin film, it is desirable to form a diffuse reflection layer. The diffuse reflection layer is preferably formed on the outermost surface of the printing and at least on the above-mentioned printed image, and can also be formed on the printed image directly or through a transparent film. In addition, when the printed image is partially formed on the substrate, it can be formed to cover the entire surface of the substrate or only on the part where the printed image is formed. The diffuse reflection layer can be made of various materials that form fine irregularities on the surface and reduce the surface gloss of the printing substrate as much as possible, but it is preferably formed of a matte varnish layer or a matte film. The matting varnish layer is formed by mixing a matting agent with a finishing varnish used as a conventional transparent top coat, and the matting film is formed by mixing a matting agent with a transparent resin film.

The finishing varnish (top coating agent) that constitutes the matting varnish layer uses a conventionally known transparent thermosetting resin, such as polyester resin, acrylic resin, epoxy resin, etc. containing thermosetting properties as the base resin and phenolic resin , Amine resin such as melamine resin, or isocyanate resin, etc. as a coating composition as a hardener and dissolved in a suitable organic solvent. In addition, the transparent resin film constituting the matting film can be formed of conventionally known transparent thermoplastic resins, such as low-density polyethylene, high-density polyethylene, polypropylene, poly-1-butene, poly-4-methyl-1-pentene, etc. Olefin resin; ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ethylene-vinyl chloride copolymer and other ethylene-ethylene copolymer resins; polystyrene, acrylonitrile-styrene copolymer, ABS, Styrenic resins such as α-methylstyrene-styrene copolymer; polyvinyl chloride, polyvinylidene chloride, vinyl chloride-vinylidene chloride copolymer, polymethyl acrylate, polymethyl methacrylate, etc. The vinyl resin; nylon 6, nylon 6-6, nylon 6-10, nylon 11, nylon 12 and other polyamide resins; polyethylene terephthalate, polybutylene terephthalate, polynaphthalene Polyester resins such as ethylene dicarboxylate; polycarbonate; polyphenylene ether; biodegradable resins such as polylactic acid. Generally speaking, from the viewpoint of excellent transparency and good heat resistance, polyesters such as polyethylene terephthalate are ideally used.

The matting agent mixed in the above-mentioned finishing varnish or transparent resin film may include, for example, those formed from inorganic particles such as silicon oxide, aluminum hydroxide, aluminum oxide, calcium carbonate, magnesium carbonate, etc.; Formers of powder or particles of organic materials such as ethylene. Among them, silicon oxide can be used particularly ideally, and among them, those having an average particle diameter in the range of 1 to 10 μm can be ideally used. When the average particle size of silicon oxide is within the above range, incident light can be effectively diffused and reflected to reduce surface gloss. Therefore, it can be visually confirmed without impairing the three-dimensional sense of surface unevenness or texture of the printed image. It is preferable that the finishing varnish or the transparent resin film contains 1% by weight or more of the resin solid content, especially a matting agent in the range of 10 to 20% by weight. When the amount of the matting agent is less than the above range, the matting effect cannot be sufficiently exhibited, and the three-dimensional effect of the printed image may be impaired. In addition, when the amount of the matting agent is more than the above-mentioned range, there is a possibility that the coatability may be poor and the flaw resistance may be lowered compared to the case within the above-mentioned range.

Due to the different uses of the printing substrate, the thickness of the diffuse reflection layer cannot be uniformly specified, but generally it should be in the range of 1-20μm for the matting varnish layer and 8-50μm for the matting film.

[Other layers] In the printing substrate of the present invention, a printed image can be directly formed on the substrate, but it can also be a base coating such as a white solid printing layer and/or an anchor coating used when forming a printing layer in the past. And the base film, etc. are formed in the middle. By forming a white solid printing layer, the background color of the metal container can be specially modified to reduce the influence on the printed image, so a clear image can be formed. In addition, when a transparent film is used as a printing substrate, a clear three-dimensional image can be formed by forming a three-dimensional printing hidden layer such as a white solid printing layer on the part where the printed image is formed. The white solid printing layer can be used as a white coating layer. For example, white pigments such as titanium oxide and zinc oxide can be dispersed in a solvent together with a thermosetting, ultraviolet curable or electron beam curable resin binder by coating. The white ink formed in the process is dried, and then cured by heating, ultraviolet irradiation, or electron beam irradiation. In addition, by forming the anchor coating, the adhesion of the printed image to the substrate can be improved. The anchor coating layer can be formed by using what is known per se as an anchor coating agent. For example, thermosetting, ultraviolet curing or electron beam curing polyester resin, thermosetting acrylic resin, epoxy resin, etc. can be applied by coating. A coating solution in which polyurethane resin or the like is dispersed or dissolved in a predetermined solvent is dried, and then cured by heating, ultraviolet irradiation, electron beam irradiation, or the like to form it.

In addition, when a label is attached to a printing base system, an adhesive layer is formed for attaching to a metal container or the like. Adhesives can be used according to the type of substrate to which the label is attached. For example, when pasting on metal containers such as seamless cans and fusion cans, use conventional thermosetting adhesives that can be easily adhered to metal containers (or resin films laminated on metal containers) by heating and pressing For example, it contains polyurethane resin, unsaturated polyester resin, polyester polyurethane resin, epoxy resin, phenol resin, alkyd resin, etc. as thermosetting resin components and contains isocyanate or melamine resin, etc. As a curing agent component, a conventional thermosetting adhesive, etc. In addition, when printing a laminate film such as a base system bag, the innermost layer can be a heat-sealable resin layer formed of polyolefin-based films such as polyethylene and polypropylene, which are conventionally known to have excellent heat-sealability.

[Irregular shape processing] In the printing substrate of the present invention, irregular shape processing can be performed on the substrate together with the pseudo three-dimensional printed image. In particular, by partially or enclosing the pseudo three-dimensional printed image and performing the irregular shape processing described later, the three-dimensional sense can also be recognized by tactile sense, thereby further improving the three-dimensional sense of the three-dimensional printed image.

(Method of manufacturing printing substrate) The manufacturing method of the printing substrate of the present invention has at least the following steps: scanning a three-dimensional scanning object with a three-dimensional scanner to produce printed data; Three-dimensional printed images.

[3D Scanning Object] The object of the original image of the printed image of the printing substrate of the present invention only needs to have unevenness on the surface, and the amount of the unevenness is not particularly limited, but even if the unevenness is 30 mm or less, a three-dimensional effect can be displayed. There are no special restrictions on such objects, but examples include: woodblock prints, oil paintings, stained glass, woven fabrics or fabrics and patchwork, etc.; materials themselves such as three-dimensional printing light-formed objects and inkjet printing hot-melt printing, etc. Printed objects, etc.; or processed objects that form three-dimensional parts such as laser engraving, machining, embossing, stamping, foaming, etc., and these objects can also be used alone or in combination of two or more to form three-dimensional scanning objects Things.

In the present invention, in addition to the above-mentioned three-dimensional objects, the three-dimensional scanning object can also be combined with most of the materials used to form an image to make the three-dimensional scanning object to emphasize the three-dimensional effect of the pseudo three-dimensional printed image. For example, by combining three-dimensional objects in a plane image to form a three-dimensional scanning object, a more three-dimensional design or decoration can be given. Specifically, by placing water droplets or ice on a flat printed image, the pseudo three-dimensional printed image can be given the refreshing feeling and juicy freshness of the water droplets that are difficult to express in conventional printing. Or, by creating a three-dimensional scanning object with various transparent concave-convex objects formed of transparent resin, glass, etc., a pseudo three-dimensional printed image with various designs with the same decorative effect as when water or ice is used can be formed. Such a transparent concave-convex object can also be formed by hot melt printing of transparent ink or the like, in addition to a molded body formed of transparent resin.

In addition, by combining two or more materials with different textures, such as a matte base material and a glossy base material, a three-dimensional object with a three-dimensional effect can be formed as a three-dimensional scanning object. In addition, by using a metal sheet or paper, or a laminate formed by combining these metal sheets or paper, a metal sheet with irregularities on the surface processed by embossing or bending, etc., as a three-dimensional scanning object Objects, even if they are not actually processed with irregular shapes, the same decorative effect can be obtained. For example, when it is very difficult to process a metal container or a paper container with irregular shapes, a pseudo three-dimensional printed image can be used to form a metal container or a paper container with irregular shape processing.

[Steps for creating printed materials] A three-dimensional scanner is used to scan the surface of the three-dimensional scanning object created as described above, and the data is edited to create a printed data. When printing by typographic printing, make a plate based on the data. The data obtained from the three-dimensional scanning object can be used as it is, and most of the data obtained from the three-dimensional scanning object can be combined to edit the data, or it can be combined with the non-three-dimensional scanned data to edit the data. As a result, the scope of printing design is expanded, and a decorative pseudo three-dimensional printed image with more excellent design can be formed.

In addition, when editing data, it is possible to create printed data that emphasizes three-dimensionality by performing conventional correction processing. The correction processing can ideally use the contrast processing that highlights the borders of different colors or brightness to control the sharpness of the three-dimensional sense or performs brightness conversion to increase the contrast of the brightness values of each pixel of the data. Sharpness processing is based on, for example, the sharpening tool (fuzzy filter) of PHOTOSHOP (registered trademark) made by Adobe Systems Co., Ltd., which sets the "amount" of the applicable sharpening amount and the width of the contour affected by the sharpening The "radius" and the "critical value" of the applicable sharpening standard are adjusted to the appropriate range according to the three-dimensional scanning object. For example, when the towel used in the embodiment is used as a three-dimensional scanning object, it is ideal that the volume is 30-60, the radius is 1 to 5 pixels, and the threshold is not used. In addition, regarding the three-dimensional scan data, by performing sharpness processing on L* (brightness) expressed in the L*a*b* color space, shadows can be emphasized and a more prominent three-dimensional effect can be given.

[Printing steps] The printing method can be printed by conventionally known methods such as inkjet printing, levelless printing, gravure printing, resin relief printing, flexographic printing, direct plate printing, screen printing, etc. However, in the present invention, it is important to Printing to form a printed image with a screen line count of more than 100lpi and/or a resolution of more than 300dpi. Thereby, the three-dimensional effect of the three-dimensional scanning object with surface unevenness can be reproduced finely and vividly. In the present invention, among the above-mentioned printing methods, it is particularly preferable to form a printed image having the above-mentioned number of screen lines or resolution by non-planographic printing or ink-jet printing. In addition, the resin relief printing used in the following embodiments is prone to produce coarse dots (edges), so by reducing the dot size on the printed plate, increasing the number of screen lines or changing the color tone according to the printed matter, a printed image close to the original image can be formed. .

In order to highlight the pseudo three-dimensional printed image, it is also possible to form the base coating of the aforementioned white three-dimensional layer or anchor coating before printing. As mentioned above, the printed image can also be used with the pseudo 3D printed image to form a printed image for displaying information. In this case, after the pseudo 3D printed image is formed, in order not to damage the decoration of the pseudo 3D printed image, it is best to spray Ink printing, etc. are formed in the non-printing area of the pseudo three-dimensional printed image. In addition, by combining with the three-dimensional pseudo three-dimensional printed image in this way, the characteristics of each can be highlighted.

When printing a pseudo three-dimensional printed image on a substrate such as a metal sheet or resin film with surface gloss, it is advisable to form the above-mentioned diffuse reflection layer on the formed pseudo three-dimensional printed image as the outermost layer of the printing substrate. The diffuse reflection layer may be either a matte varnish layer or a matte transparent resin film.

[Irregular shape processing steps] By performing irregular shape processing in accordance with the pseudo three-dimensional printed image on the printing substrate forming the pseudo three-dimensional printed image, the three-dimensional effect of the pseudo three-dimensional printed image can be further improved. That is, with the pseudo three-dimensional printed image, the three-dimensional sense recognized by vision can also be further recognized by the sense of touch, so that the prominent three-dimensional sense can be felt. Due to the type of substrate and the shape of the printing substrate, irregular shape processing cannot be specified, but the conventional irregular shape processing such as mechanical processing such as bending processing, embossing processing, stamping, etc. can be used, and it can be used with pseudo three-dimensional printed images. The unevenness is formed on the substrate in a way that partly and/or surrounds the entire circumference along the outline of the image. [Example]

Although the effects of the present invention are demonstrated by the following experimental examples, the present invention is not limited to these examples.

(Experimental example 1) A towel is used as a three-dimensional scanning object, and a three-dimensional scanning device (product SCAMERA-Face manufactured by NEWLY Corporation) is used to obtain three-dimensional scanning data on the surface of the towel. Figure 2(A) shows a photo obtained by sharpening the three-dimensional scan data (600dpi) (amount 35, radius 3 pixels, no threshold value). Use the obtained three-dimensional scan data to change the number of screen lines to (A) 80lpi, (B) 100lpi, (C) 120lpi, (D) 150lpi, (E) 250lpi, (F) 300lpi to make a non-horizontal version, and then print On the aluminum plate. The photo of the printed image on the aluminum plate with a magnification of 3 times is shown in Figure 3. It can be seen from Fig. 3 that when the screen line number is more than 100 lpi, the yarn loop of the towel is clear, and the more the line number, the more obvious the three-dimensional effect and the closer to the data photo shown in Fig. 2(A). It can also be known that the dots are recognized at 80lpi, and the three-dimensional effect is lacking compared with those above 100lpi.

(Experimental example 2) A towel is used as the object, and a monocular camera is used to obtain three-dimensional scan data on the surface of the towel. Figure 2(B) shows the photos obtained from the image data. Except for using the obtained image data, in the same way as in Experimental Example 1, the number of screen lines was changed to 80lpi, 100lpi, 120lpi, 150lpi, 250lpi, 300lpi and made into a non-horizontal plate, and then printed on the aluminum plate. The photo of the printed image magnified 3 times is shown in Figure 4. It can be seen from FIG. 4 that compared to FIG. 3, the three-dimensional effect is lacking and the sharpness is insufficient when the number of screen lines is small.

(Experimental example 3) Using the same three-dimensional scanning data as in Experimental Example 1, the number of screen lines was changed to (A) 80lpi, (B) 100lpi, (C) 120lpi, (D) 150lpi, to make a resin relief plate, and then print it on an aluminum plate. The photo of the printed image magnified 3 times is shown in Figure 5. It can be seen from Figure 5 that the more screen lines, the more vivid the yarn loops of the towel and the better the three-dimensional effect. However, compared with Figure 3 where the same printed image is printed with no horizontal plate, the thick dots (edges) unique to resin letterpress printing are produced and become The image is darker than the data photo shown in Figure 2(A), so the image without the horizontal version is brighter and closer to the data photo shown in Figure 2(A).
