Description

  The present invention relates to a printed material on which a gold foil is pasted, and more specifically, relates to a printed material on which a painting on which a gold leaf such as a Japanese painting drawn on a wall or ceiling surface or a painting is pasted is reproduced.

  Cultural heritage such as Japanese paintings painted with gold leaf on the walls and ceilings, or on the walls and ceilings, have been affected by the natural environment such as temperature, humidity or sunlight for many years. However, as aging progresses year by year due to the effects of air pollution and the like, it is in a serious situation how this will be passed on to future generations.

  Therefore, while the restoration of the aged cultural heritage is being promoted, on the other hand, the aging actual thing is carefully stored in a storage etc., and the movement to replace the aged real thing with a replica has been activated. Yes.

  By the way, the actual reproduction (in-kind) copying or reproduction copying has been the mainstream until now, but since the copying is handwritten one by one, the production days are extremely long and the production cost is also high. In addition to the enormous size, it may be a reproduction that includes the interpretation and subjectivity of the painter to be copied, and may not be able to express the intention of the real artist. In particular, the current (actual) replication has the problem that it is extremely difficult to faithfully reproduce the subtle stains and discoloration of the foil feet currently seen.

  In addition, duplicates by copying are defenseless against natural disasters such as earthquakes, typhoons, and human disasters such as fires and human damage, and once damage occurs, it is necessary to copy from the real thing again. The replication problem that occurred again occurs. Also, in this case, even though the real thing is carefully stored in the storage, etc., the aging is further progressing, and it is the first to copy either the current (actual) copy or the reproduction copy. This is even more difficult than the copy of

  Therefore, the present invention has been made to solve the above-mentioned problems, and is a reproduction of a painting such as a Japanese painting drawn in a brilliant color while sticking a gold leaf on a folding screen, folding screen, wall surface, ceiling surface, etc. It is to provide a printed material that more faithfully represents the actual object than copying and has a shorter production time and lower manufacturing cost than copying. It is another object of the present invention to provide a printed material that can be easily reproduced even if the printed material is damaged or disappears due to a disaster or the like.

  As a result of the inventor's studies to achieve the above object, the printed matter according to claim 1 has a gold foil attached to one surface of a paper substrate via an adhesive layer, and the gold foil. A printed pattern layer is formed thereon.

  Moreover, the printed matter of the invention according to claim 2 forms a gold foil region and a non-gold leaf region by sticking a gold foil partially on one surface of a paper base material via an adhesive layer, and at least the above-mentioned The pattern printing layer is formed in the non-gold leaf region.

  The invention according to claim 3 is the printed matter according to claim 2, wherein a pattern printing layer is formed in the gold foil region.

With this configuration, it is possible to obtain a Japanese paper that is less susceptible to the influence of the fountain solution (expansion and contraction of the Japanese paper) when the pattern printing layer or the like is formed by offset printing.

  The printed matter of the present invention faithfully represents the real thing as a reproduction of a painting such as a Japanese painting drawn in a colorful color with a gold leaf pasted on a wall or ceiling, or on a wall surface or ceiling surface, etc. Can be printed. In addition, since the actual image information is captured as digital data in the process of manufacturing the printed material, it can be easily reproduced even if the printed material is damaged or disappears due to a disaster or the like. Furthermore, the printed matter of the present invention can be manufactured in a shorter number of days and less expensive than copying.

The above-described present invention will be described in detail below with reference to the drawings.
1 is a front view showing an embodiment of a printed material according to the present invention, FIG. 2 is a cross-sectional view taken along line I-I in FIG. 1, and FIG. 3 is an explanatory view of the method for producing a printed material according to the present invention. 1 is a printed material, 2 is a paper substrate, 3, 3 'is a gold foil, 4, 4' is a pattern printing layer, 10 is an adhesive layer, 20 is a mount, 30 is a heat and UV resistant tape, and 40 and 41 are for printing. Each mount is shown.

  FIG. 1 is a front view showing an embodiment of a printed material according to the present invention, FIG. 2 is a cross-sectional view taken along the line II of FIG. 1, and the printed material 1 comprises a paper base material 2 on the left half surface of FIG. The gold foil 3 is attached via the adhesive layer 10 (see FIG. 2), and the gold foil 3 ′ is attached to the right half surface in the shape of “F” via the adhesive layer 10 (see FIG. 2). ing. And the pattern printing layer 4 is provided on the paper base material 2 other than the gold foils 3 and 3 'formed, and the pattern printing layer 4 is provided in a tweezer state at the boundary with the gold foils 3 and 3'. (Normally, the pattern print layer 4 is drawn with a gorgeous color such as Katori Kazuki). Further, a pattern printing layer 4 ′ having a shape of “A” is provided on the gold foil 3 on the left half surface. The pattern print layer 4 ′ may be a single color letter or symbol such as “A”, or may be a colorful color depicting a flower-bird-like moon, etc. It may be a representation of dirt and spots adhering to the gold leaf between the two.

  By the way, as a printing method for obtaining the printed matter 1 shown in FIG. 1, the adhesive layer 10 provided for sticking the gold foils 3, 3 ′ to the paper substrate 2, or the pattern printing layers 4, 4 ′ 10, etc. It is necessary to print several colors together with the printing register. Considering the printing register accuracy, the silk screen printing method or the offset printing method, or the printing method that combines these two printing methods can be mentioned. Since the printing method transfers ink to the paper substrate 2 through the screen mesh, there is a problem in that the trace of the screen mesh remains on the printing surface, which hinders the reproducibility of color tone and old color, and silk screen The combination of the printing method and the offset printing method has a problem in terms of printing registration accuracy, and the offset printing method is appropriate. In addition, the offset printing plate used when the printed matter 1 of the present invention is printed by the offset printing method is designed to prevent FM (Frequency Modulation) in order to prevent moiré and rosette patterns (commonly referred to as flower patterns) that occur during multicolor printing. ) Preferably, halftone dots are formed on the screen.

  The paper base 2 may be either Western paper or Japanese paper as long as it is printable, and is not particularly limited. Paper that can represent the real thing most faithfully can be appropriately selected and used. . However, if the actual thing is a picture drawn on Japanese paper and a copy of this picture is produced by the offset printing method, the Japanese paper (water It is necessary to use a Japanese paper with less expansion and contraction, and a paper made with a mixed fiber of scabbard fibers and trifilar fibers is suitable as a compatible Japanese paper. In particular, the mixing ratio between the cocoon fiber and the cocoon fiber is preferably 50% to 70% by weight of the cocoon fiber and 50% to 30% by weight of the cocoon fiber. The Echizen Japanese paper Torinoko No. 2 paper with 40% by weight fiber is particularly suitable. In general, cocoon fibers are often used for Japanese paper, but the cocoon fibers are unsuitable as the Japanese paper used for the printed matter 1 of the present invention because of their long fiber length and intense expansion and contraction by dampening water.

  Moreover, as printing ink which forms the said adhesive bond layer 10, it is used in order to stick the gold | metal foils 3 and 3 'to the paper base material 2, Specifically, sand paste, cloth nori, hime glue, glue, etc. Is generally used because it maintains a suitable viscosity for a certain period of time until the gold foils 3 and 3 'are adhered, but considering that printing can be performed by an offset printing method, an ultraviolet curable type is used. A printing ink made of a resin (a state in which an uncured viscosity is maintained until cured by irradiation with ultraviolet rays) is preferable in that it meets the above requirements.

  Among them, as the ultraviolet curable resin used for the printing ink for forming the adhesive layer 10, the adhesive strength with the gold foils 3, 3 ′ is not inferior to that of conventional adhesives such as sand paste, cloth laver, princess paste, glue, etc. In order to achieve this, an ultraviolet curable epoxy acrylate resin is suitable. The ultraviolet curable epoxy acrylate resin is obtained by adding an epoxy acrylate resin (a resin obtained by acrylic-modifying an epoxy resin obtained by causing epichlorohydrin to act on bisphenol A) to a polyester acrylate ultraviolet curable resin. As the printing ink for forming the adhesive layer 10, the addition ratio of the epoxy acrylate resin for adhering the gold foil 3, 3 ′ to the paper substrate 2 is 15 to 35 wt% with respect to the polyester acrylate UV curable resin. More preferably, it is 20 to 30% by weight. If the addition ratio is less than 15% by weight, the resin penetrates into the paper substrate 2 and the adhesiveness for bonding the gold foils 3 and 3 'cannot be obtained. Even if the resin is cured by irradiating ultraviolet rays, the gold foil The adhesive strength with 3, 3 ′ cannot be obtained. Further, if the addition ratio is more than 35% by weight, it becomes unsuitable as offset printing ink that requires hydrophobicity (this is because “fountain solution” is used in offset printing, so that the ink is not emulsified with water. For).

  The printing ink made of the ultraviolet curable resin for forming the adhesive layer 10 starts photopolymerization with fillers such as precipitated barium sulfate and calcium carbonate in addition to the ultraviolet curable epoxy acrylate resin to maintain printability. The UV curable epoxy acrylate resin includes, for example, Lipoxy SP-1519M (manufactured by Showa Polymer Co., Ltd.), Evecryl 3700 [Daicel] UCB Co., Ltd.]. The adhesion part of the gold foils 3 and 3 ′ obtained by irradiating and curing the adhesive layer 10 formed with the printing ink thus configured has rigidity, and is excellent in chemical resistance and heat resistance. Also, the adhesive strength can be prevented from decreasing with time (yearly unit).

  Further, as the printing ink made of the ultraviolet curable resin for forming the pattern printing layers 4 and 4 ′, the same printing ink as the ultraviolet curable resin described in the adhesive layer 10 can be used.

  The pigment used in the printing ink for forming the pattern printing layers 4 and 4 'is one that has very little discoloration or discoloration over time (yearly) when the printed material 1 is placed indoors in a normal ordinary house. It is necessary to use it. Examples of the pigment suitable for this include higher organic pigments and inorganic pigments. Examples of higher organic pigments include, for example, isoindolinone-based, benzimidazolone-based, selenium-based, monoazo-based, and condensed azo-based pigments for yellow, and quinacridone-based pigments for red and red. , Monoazo, condensed azo, perylene, etc., orange pigments such as isoindolinone, and verinone pigments, and blue, indigo and green pigments such as phthalocyanine pigments. Examples of purple pigments include dioxazine and quinacridone. Examples of the inorganic pigment include yellow lead, yellow iron oxide, cadmium yellow and the like as yellow pigments, and red shells such as valve shell and cadmium red, and blue and purple pigments. Examples include ultramarine blue, bitumen, chromium oxide, cobalt blue, cobalt green, and manganese violet. Carbon black is used as a black pigment, and titanium oxide is used as a white pigment. In addition, metal powders such as aluminum powder and bronze powder, or extender pigments such as calcium carbonate, barium sulfate, alumina white, and silica can be used. Note that the above-described pigment may be added to the printing ink made of an ultraviolet curable resin for forming the adhesive layer 10 as necessary.

  The adhesive layer 10 and the pattern printing layers 4 and 4 ′ are formed using a printing ink made of the ultraviolet curable resin as described above and a printing ink obtained by adding a pigment or the like to the ultraviolet curable resin. As a result, it is possible to obtain a printed material that does not deteriorate the adhesive strength and is extremely little discolored or discolored when placed in a normal ordinary house for at least 30 years, more preferably 50 years.

Next, the manufacturing method of the printed matter 1 of this invention shown in FIG. 1, FIG. 2 is demonstrated.
First, a gold foil is affixed to the paper base 2 and a real object (not shown) drawn in a brilliant color using a paintbrush and paint is captured as an image by a photograph or the like. (Aka, Ai, Sumi) to make a reference plate by color separation, and make a special color plate of the required number of colors with a color that cannot be expressed by the four-color reference plate that has been color-separated, and affix a gold foil An adhesive plate for forming the adhesive layer 10 and an atlas ruled line plate indicating the position of the adhesive layer 10 are prepared.

Next, on mount 20 [Mitsubishi Paper Co., Ltd .: N-Pearl DX (290 g / m ² )] where at least two sides are orthogonal (one side is the occlusion side and the other side is the needle side during offset printing) Printing as shown in FIG. 3A in which the paper base 2 is placed and the paper base 2 is fixed with a heat-resistant and ultraviolet-resistant tape 30 on one side of the mount (the bite side during offset printing). A mount 40 is produced. Using this printing mount 40, first, the gray ruled line printing (not shown) indicating the position for sticking the gold foil to the paper base material 2 with the printing ink made of an ultraviolet curable resin is used. In addition, the adhesive layer 10 (not shown) for adhering the gold foil in register with the attried ruled line printing (not shown) is abbreviated with a yellow pigment and a red pigment on an ultraviolet curable epoxy acrylate resin. Printing is performed using a printing ink made of an ultraviolet curable resin colored in gold, using the adhesive plate, and a gold foil is pasted on the adhesive layer 10 (not shown) and pressed with valen, or an overlapping portion of the gold foil or Unnecessary parts are removed, and then the gold foil is applied to the gold foil surface by applying pressure to the gold foil surface so that the gold foil is completely adhered, and after removing the thick paper, the printing substrate is irradiated with ultraviolet rays to radiate the purple. The printing ink comprising a line-curable resin is completely cured to give a printed carrier sheet 41 gilt 3,3 'is adhered to paper substrate 2 shown in FIG. 3 (b). After that, a cinnabar liquid is applied to the gold foil surface and air-dried to prevent the peeling of the gold foil, and then the above-described reference plate and special plate on the gold foil 3 and the non-gold leaf surface of the paper base 2 In addition, the pattern printing layer 4 ′ (see FIG. 1) and the pattern printing layer 4 (see FIG. 1) having a shape of “A” are printed with printing ink made of an ultraviolet curable resin, and the pattern is irradiated with ultraviolet rays. After the printed layers 4 and 4 '(see FIG. 1) are completely cured, the paper base 2 is removed from the mount 30, and the four sides are trimmed [trimmed by the alternate long and short dashed lines shown in FIG. The print 1 of the present invention shown is obtained.

  By the way, when using Japanese paper as the paper base material 2, for example, Torinoko Tokugo No. 2 paper, if the sand is applied to the gold leaf surface and dried naturally, the Torinoko Tokugo No. 2 paper warps. Arise. In this case, it is necessary to provide means for removing the warp (making it flat). As this means, for example, the warp can be removed by uniformly applying water to Torikoshi No. 2 paper, sandwiching it with a smooth metal plate and pressing it. Furthermore, when Japanese paper, for example, Torinoko Tokugo No. 2 paper is used, it is desirable to use the back side on which the fibers of the Japanese paper are fuzzy as the printed surface in order to express the texture of the printed material as it is.

  In the above description, the gold foil 3 ′ provided in the shape of “F” can be formed by sprinkling gold powder instead of the gold foil. If necessary, the gloss of the pattern printed layers 4 and 4 ′ is erased for the purpose of preventing the gold foil from being oxidized and preventing the discoloration of the gold color, to improve the wear resistance and the scratch resistance, or ( For the purpose of matting), a protective layer (not shown) may be provided on the pattern printing layers 4 and 4 ′ or on the entire surface with OP varnish or the like.
