Description

  The present invention relates to a printed matter on which a gold foil is pasted, and more particularly to a printed matter 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 a wall or ceiling surface, or painting on a wall or ceiling, has 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 promoted, on the other hand, while the aged real thing is carefully stored in a storage, etc., the movement to replace the aged real thing with a replica has become active. 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 stored in the storage, etc., the aging is further advanced, 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 applicant has previously proposed a method in which printing of the adhesive layer and the pattern portion is performed by offset printing as a printed material in which a gold foil is attached to one surface of a paper substrate via an adhesive layer. If this method is used, a copy with higher accuracy than the conventional one can be obtained, but further improvement is required in terms of registration accuracy, and when there is a shift in pattern printing in the copy creation process, There has been a demand for improvement in cost, for example, a gold foil already stuck is wasted.

  The printed matter of the present invention is a printed matter that faithfully represents the real thing as a replica of a painting such as a Japanese painting drawn in a colorful color while affixing a gold leaf on a wall or ceiling surface, etc. Can do. 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, by using the manufacturing method of the present invention, the number of manufacturing days can be shortened and the manufacturing cost can be reduced.

Hereinafter, embodiments of the present invention will be described in detail 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, 3 is a paper substrate, 5 is a pattern printing layer, 7 is an adhesive layer, 9, 9 'is a gold foil, 11 is a pattern printing layer on the gold foil, 21 is a mount, 23 is a heat-resistant UV-resistant tape, Reference numerals 31 and 33 denote printing mounts, respectively.

  The printed material 1 is a reproduction of a painting such as a Japanese painting drawn with a gold leaf on a wall or ceiling surface, or a gold leaf on a wall surface or ceiling surface. The printed material 1 includes a pattern printing layer 5 on a paper substrate 3. An ink-jet printing area and a gold foil area composed of gold foil layers 9 and 9 ′ attached via an adhesive layer 7 are provided.

  The printed material 1 has a gold foil 9 attached to the left half of FIG. 1 via an adhesive layer 7 (see FIG. 2) and “F” to the right half of the printed material 1 via an adhesive layer 7 (see FIG. 2). A gold foil 9 'is attached to the shape. Then, the pattern printing layer 5 is provided on the paper base 3 other than the gold foils 9 and 9 '. The picture print layer 5 is provided in a tweezers state at the boundary with the gold foils 9 and 9 '(usually, the picture print layer 5 is drawn with a brilliant color such as Katori Katsuki).

  Further, a pattern printing layer 11 on a gold foil having a shape of “A” is provided on the gold foil 3 on the left half of FIG. The printed pattern 11 on the gold leaf may be a single-colored letter or symbol such as “A”, or may be drawn in a colorful color such as a flower-and-bird moon or the like. It may be a representation of stains and stains attached to the gold leaf during the moon.

The pattern printing layer 5 is formed by inkjet printing.
The printing ink used for inkjet printing may be any of aqueous pigment ink, UV curable ink, and any inkjet ink.

  It is appropriate to form the adhesive layer 7 and the gold foil pattern printing layer 11 by offset printing. In addition, the offset printing plate used for offset printing forms halftone dots on an FM (Frequency Modulation) screen to prevent moiré and rosette patterns (commonly called flower patterns) that occur during multicolor printing. It is preferable to do this.

  The paper base 3 is not particularly limited as long as it can perform inkjet printing and offset printing, and can be selected and used as appropriate, as long as it can faithfully represent the real thing. When the actual thing is a picture drawn on Japanese paper, and a copy of this picture is made, it is preferable to use Japanese paper.

The paper base 3 is preferably coated with a surface treatment material that retains ink jet ink suitability. The surface-treated material is not particularly limited. For example, silica binder and polyfix 700 (Showa Polymer) whose main component is an ethylene-vinyl acetate copolymer such as Polysol AM-3000 (manufactured by Showa Polymer Co., Ltd.). Ink fixing agents mainly composed of specially modified polyamines such as those manufactured by K.K. are preferred, and these are applied in an amount of about 5 g / m ² .

In addition, the Japanese paper used for the paper base 3 is of course not a problem if it is an inkjet paper consisting only of scabbard fibers and trilobal fibers that are less susceptible to water, considering the effect of moisture expansion and contraction on printing accuracy. Ink jet paper composed only of trilobal fibers inevitably suffers from the cost problem of high paper cost.
On the other hand, in the present invention, the pattern printing layer 5 is formed by ink jet printing, so it is also possible to use Japanese paper containing straw fibers that are easily affected by water. Specifically, a single-layered winged-bird ink-jet paper comprising 40% by weight of cocoon fiber + tri-filament fiber + Manila, 40% by weight of pulp, and 20% by weight of cocoon fiber has improved printing accuracy in the printed matter manufacturing method of the present invention. It is particularly suitable in terms of securing and cost reduction.

  Moreover, as printing ink which forms the adhesive bond layer 7, it is used in order to stick the gold foils 9 and 9 'to the paper base material 3, and specifically, sand paste, cloth nori, hime glue, glue, etc. It is generally used because it maintains a suitable viscosity for a certain period of time until the gold foils 9 and 9 'are attached. However, considering that printing can be performed by an offset printing method, an ultraviolet curable resin is used. A printing ink composed of (a state in which an uncured viscosity is maintained until cured by irradiation with ultraviolet rays) is preferable.

  As an ultraviolet curable resin used for the printing ink for forming the adhesive layer 7, the adhesive strength with the gold foils 9 and 9 'is not inferior to that of conventional adhesives such as sand paste, cloth laver, princess paste and glue. For 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 7, the addition ratio of the epoxy acrylate resin for adhering the gold foils 9 and 9 ′ to the paper substrate 3 with respect to the polyester acrylate ultraviolet curable resin is 15 to 35% by weight, More preferably, it is 20 to 30% by weight. When the addition ratio is less than 15% by weight, the resin penetrates into the paper substrate 3 and the adhesiveness for bonding the gold foils 9 and 9 ′ cannot be obtained. Even if the resin is cured by irradiating ultraviolet rays, the gold foil Adhesive strength with 9, 9 ′ 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 comprising the ultraviolet curable resin for forming the adhesive layer 7 includes a filler such as precipitated barium sulfate and calcium carbonate and a photopolymerization initiator in order to maintain printability in addition to the ultraviolet curable epoxy acrylate resin. A UV-curable epoxy acrylate resin such as Lipoxy SP-1519M (manufactured by Showa Polymer Co., Ltd.), Evecryl 3700 (Daicel UCB) Manufactured by Co., Ltd.]. The adhesive part 7 of the gold foil 9, 9 ′ obtained by irradiating and curing the adhesive layer 7 formed with the printing ink configured in this way has rigidity, is excellent in chemical resistance and heat resistance, It can be assumed that the adhesive strength does not decrease with time (yearly unit).

  In addition, as the printing ink made of the ultraviolet curable resin for forming the pattern print layer 11 on the gold foil, the same printing ink as the ultraviolet curable resin described in the adhesive layer 7 can be used.

  As the pigment used for the printing ink for forming the pattern printed layer 11 on the gold foil, it is necessary to use a pigment that has very little discoloration or discoloration over time (yearly) when the printed material 1 is placed in a normal ordinary house. There is. 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, and the like, orange pigments such as isoindolinone and verinone, and blue, indigo and green pigments such as phthalocyanine. 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 the ultraviolet curable resin for forming the adhesive layer 7 as necessary.

  By using a printing ink composed 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, the adhesive layer 7 and the pattern printing layer 11 on the gold foil are formed. It is possible to obtain a printed material that does not deteriorate the adhesive strength and is extremely little discolored or discolored under the condition of being 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 attached to the paper base 3 and a real object (not shown) drawn with a paintbrush and paint is drawn as an image (positive film) with a photograph or the like, and the captured image is read with a scanner. Standard data is created by separating the color into four colors (ki, red, eye, and sumi), and special color data is created for the number of colors required for the color that cannot be represented by the four-color separated standard version. The adhesive layer data for creating the adhesive layer at the sticking position and the print pattern data on the gold foil are created.

  Next, on the basis of the reference data and the spot color data, a pattern is printed by an inkjet output machine within a range where the gold foil of the paper substrate 3 is not adhered, and the pattern printing layer 5 is configured.

Next, on mount 21 [Mitsubishi Paper Co., Ltd .: N-Pearl DX (290 g / m ² )] where at least two sides are orthogonal (one side is the occlusal side and the other side is the needle side during offset printing) The paper substrate 3 constituting the pattern printing layer 5 by the inkjet printing is placed, and the paper substrate 3 is taped with a heat-resistant and ultraviolet-resistant tape 23 on one side of the mount (the bite side during offset printing). A fixed mount 31 for printing as shown in FIG.

  Next, an offset printing plate (adhesive layer plate, reference plate, special color plate) is prepared using the previously created adhesive layer data, printed pattern reference data on gold foil, and spot color data.

  The adhesive layer plate (not shown) for adhering the gold foil is made of ultraviolet curable epoxy acrylate resin with a yellow ink and a red pigment, and the adhesive layer plate is printed with a printing ink made of an ultraviolet curable resin colored in a substantially gold color. Using the offset printing, the adhesive layer 7 is formed, and the gold foil is pasted on the adhesive layer 7 (not shown) and pressed with valen to remove the overlapping or unnecessary portions of the gold foil, and then the gold foil surface Applying a thick paper such as the above mount to apply pressure to make the gold foil adhere completely, remove the thick paper, and then irradiate the printing mount with ultraviolet rays to completely cure the printing ink made of the UV curable resin. Thus, a printing mount 33 in which the gold foils 9 and 9 ′ shown in FIG. Then, dredged sand solution is applied to the surface of the gold foil and dried naturally to prevent the peeling of the gold foil. Thereafter, the pattern printing layer 11 (see FIG. 1) on the gold foil 9 is irradiated with ultraviolet rays with the above-mentioned standard plate and special plate. Offset printing is performed using printing ink made of a curable resin, and after the pattern printing layer 11 (see FIG. 1) is completely cured by irradiating with ultraviolet rays, the paper base 3 is removed from the mount 21, and the four sides are removed. Trimming (trimming along the alternate long and short dash line shown in FIG. 3B) is performed to obtain the printed matter 1 of the present invention shown in FIG.

  In the above description, the gold foil 9 ′ provided in the shape of “F” can be formed by sprinkling gold powder instead of the gold foil. If necessary, the metallic foil is oxidized for the purpose of preventing the discoloration of the gold color, for the purpose of improving the wear resistance and the scratch resistance, or for the matte tone of the picture printed layer 11 to be erased. For this purpose, a protective layer (not shown) may be provided on the pattern printing layer 11 or on the entire surface with OP varnish or the like.

As described above, according to the present invention, the real thing is more faithfully represented as a replica of a painting such as a Japanese painting drawn in a colorful color while sticking a gold leaf on a folding screen, folding screen, wall surface, ceiling surface, or the like. Can be printed.
Further, by performing ink jet printing in areas other than the gold foil region, the printing time is shortened and the influence of moisture is small, so that the registration accuracy is improved, and a paper base material containing cocoon fibers can be used, and the cost is low. Furthermore, even if a deviation occurs in ink jet picture printing, the gold foil is not wasted because it is before sticking the gold foil.

It is a front view which shows one Example of the printed matter concerning this invention. It is sectional drawing of the II line | wire of FIG. It is explanatory drawing of the manufacturing method of the printed matter concerning this invention.
