Abstract

PURPOSE:To obtain a print to which creativeness and quality are imparted by extracting a drawing line/contour of the original picture of a painter by photoengraving technique and applying coloration treatment to an Al plate having an anodic oxidation treatment film formed thereto and coloring the residual part by the painter using the multicolor dye fitted to the anodic oxidation film and entering a sign before applying sealing treatment. CONSTITUTION:An anodic oxidation film is applied to an Al plate and dyeing, electrolytic coloration and sealing treatment are applied thereto and a photosensitive emulsion is applied and dried. The drawing line/contour of the original picture of a painter is photographed by a plate making camera and this film is brought into close contact with the Al plate and a photosensitive film is exposed to ultraviolet rays to be developed and, when the developed Al plate is etched, a part becoming the skeletal of a picture is colored to appear and, at the other part, matte metal texture is exposed. A colorless transparent anodic oxidation film is newly formed to this texture part and colored with oily Al paint by the painter using a paintbrush and a sign and an edition number are entered. This treated Al plate is subjected to sealing treatment one at a time to fix a dye. By this method, a plurality of prints of high creativeness can be prepared efficiently and there is also no possibility of damage.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses an aluminum metal plate as an art material for printmaking, and makes full use of the anodic oxide coating technology on the surface of the plate to create original prints made with brushstrokes by artists. As a highly durable print, it is suitable for interior wall decoration and viewing, as well as as a tabletop decoration.

[Prior art] It is common knowledge that conventional prints are produced using paper as the art material, and therefore, this paper is extremely susceptible to damage such as stains and bending, as well as discoloration and fading due to light rays. It has been kept in a frame that protects it from sunlight and has been presented exclusively for viewing indoors with limited lighting.

On the other hand, there have been decorations made by coloring the surface of metal materials such as aluminum, but these are purely industrial products made by applying various printing techniques, and they are also made by applying photolithography and anodizing techniques. Some paintings have been made into products, but due to limitations in process technology, most of them are monochromatic or two or two colors.
It was a simple item with only three colors, and was at a stage where it could not be called a craft. Furthermore, since the original authors were not involved in the printmaking process in any of these, they were still nothing more than reproductions.

[Problems to be solved by the invention] As mentioned above, conventional prints have extremely poor weather resistance, and highly artistic original prints must be stored in a cool, dark place with constant humidity at all times for fear of deteriorating the value of the work. It is customary to take out prints and appreciate them only occasionally, and this has become a factor that has hindered the spread of prints.

On the other hand, in households with increased living margins, there is an increasing demand for paintings and prints to be displayed on walls to decorate the interior of the room, but original paintings and pure original prints are expensive and difficult to obtain. The market is flooded with a large number of reproduction prints for interior decoration, which are difficult to enter into the realm of original prints, and various problems have arisen in connection with these, and the current situation is that buyers are not fully satisfied. .

[Means for solving the problem] Mitsumei uses an efficient industrial method to reproduce the skeleton that makes up the screen of the original painting drawn by the artist on a metal plate, and then the artist paints it with his own brush. By producing prints using this method, it is possible to produce multiple original prints that are slightly different for each item, reducing the burden on the artist, thereby providing creativity and quality that satisfies the purchaser, and at a relatively low cost. It is intended to provide.

The current definition of an original print is that the print meets any of the following conditions.

(1) The artist himself did everything from the sketch to the plate making and printing himself.

(2) The artist himself created the sketch and print, and the printing was done by a technician under the artist's supervision.

(3) The artist himself drew a rough sketch, and an engineer created and printed the plates using the type of plate that suited the artist's expressive intent.

Furthermore, each work produced under these conditions is required to have the artist's signature and an edition number (limited number of prints and number of the work).

This invention mainly adopts the Qm process described in (3) above, and on top of this, the artist adds brushstrokes corresponding to process (1) to further enhance originality, and artistically it is not conventional. Compared to coloring using anodizing techniques, the degree of freedom in coloring is greatly increased, making it possible to create multiple colors and freely mix colors. In addition, during this production process, the production of intermediate products before the artist colors them is carried out uniformly by workers at the factory using a manufacturing method that conforms to predetermined work standards, so that the products are supplied as completely uniform industrial products. There is no room for any personality other than the artist to enter. Therefore, everything expressed on the screen of the final work is the result of f91 work based on the artist's production intention, and if multiple pieces are produced, the expression will be slightly different for each piece, so it will not be considered a print. The originality of the pieces is extremely high, and in accordance with the requirements for ordinary printmaking, the signature and edition number can be written on each piece by hand by the artist, so there is no consideration given to preventing duplication.

[Function] This invention combines aluminum anodizing technology and brush painting by the artist to reduce the burden on the artist while giving each piece an originality that is not found in other metal ornaments. It can also be used for production. Furthermore, since the skeleton of the sketch drawn by the artist is reproduced on the screen in advance, the artist can use this as a standard for coloring, and it is also possible to finish it as a completely different print based on the free ideas of the moment. For example, in the case of landscape prints, the season can be freely changed at the brush coloring stage, allowing the artist to change the coloring to a summer landscape, autumn leaves, or winter snowscape, while still being original. It can be completed as a completely different work.

Regarding the longevity of prints, the anodic oxide film has extremely high hardness and excellent corrosion resistance, so it does not necessarily have to be placed in a frame with a glass front, which prevents light from reflecting on the glass surface and making it difficult to see the picture. There is no such thing.

Also, even if the aluminum surface is displayed in a place where the public can directly touch it, there is little risk of damage, and it will not get dirty with graffiti etc. Even if the anodic oxide film is sealed, it no longer accepts contamination from the outside, so it can be easily restored by washing with detergent and water. Therefore, it is suitable not only for personal collection but also for public use and interior decoration in public places such as halls, public halls, station waiting rooms, hotels, and ship cabin walls. If the signature and edition number are written with dye or signature bene before the sealing process, they will be dyed into the anodized coating like the colored parts during the sealing process and will not fall off semi-permanently. It is much more durable than the pencil version.

[Example 1] Figures 1 and 2 show an example of the process of producing a print according to the present invention, Figure 3 shows a state in which only the skeleton of the print work is reproduced, and Figure 4 shows a completely produced print. Here is an example.

First, the steps in FIG. 1, in which etching is used to reproduce the skeleton of the picture, will be explained in order.

(1) First step: The aluminum rice grain used in the present invention has a low content of silicon, etc., and therefore has good alumite properties and a transparent anodic oxide film according to JIS-105.
0. 1070. A pure aluminum plate such as 1080 is cut to the required size. Depending on the degree of gloss desired in the original drawing of the skeleton, the surface condition is adjusted by pre-treatment, such as whether it is glossy or matte. The plate thickness is 0.
3~o. The thickness is good, and the larger the picture, the thicker it should be. An anodic oxide film with a thickness of at least 510 μm or more is applied to this, and the entire surface is dyed or electrolytically colored in the color that constitutes the frame of the screen, such as black or brown, and the pores are sealed to increase the durability of the film. In addition to increasing the coloring, it also prevents blurring during coloring. Thereafter, a photosensitive acid- or alkali-resistant emulsion (photoresist) is thinly and uniformly applied to the entire anodized film and dried to form the photosensitive film.

(2) Second step: Using a plate-making camera, the parts of the original picture or sketch drawn by the two artists, such as the lines and outlines that form the framework, are captured as negative images on film using methods such as color separation. . In this case, if it is necessary to add shading to the drawing lines that serve as the skeleton, a lithographic film using halftone dots may be used. In addition, in the case of a picture that is a combination of colored parts that have no skeleton or outline at all during plate making, select one color that occupies a large proportion of the screen and can represent the screen, and use a filter etc. to only use this color. All you have to do is disassemble and extract it and make a plate to form the skeleton of the screen.

(3) Third stage: Using the film produced in the previous step, the photoresist film on the anodic oxide film is exposed to ultraviolet rays by closely contacting the aluminum plate prepared in the first step, and then developed and unexposed. After removing a portion of the photoresist film, it is immersed in an acid or alkaline etching solution that dissolves the anodic oxide film. At this time, the image of the part exposed with the negative film, that is, the above-mentioned skeleton part of the original picture, is because the photoresist film is exposed to photochemical reaction. The surface is protected by remaining hardened by the reaction, so it is not dissolved and the colored anodic oxide coating layer on the surface that is not exposed to light is dissolved to reveal the aluminum metal surface that is the base material of the R layer. . When the remaining photoresist film was peeled off, the skeleton of the painting was colored and exposed, while the rest of the painting was etched away, exposing the dull metal surface. The color tone of this background surface can be influenced by the selection of etching solution, etching conditions, etc., and can range from a semi-gloss tone with a slight metallic feel to a white background state with no gloss at all.

Note that there is a screen printing method in which the skeleton portion is left by etching during this process. This is done by not coating the aluminum art material with a photoresist film after the puncture treatment in which the anodic oxide film is colored in the first step. This is a method in which the skeleton part is made on a screen plate for screen printing, and then screen printed on the colored film of the art material using acid- and alkali-resistant resist ink to form a protective film, and the other parts are etched. Similarly, the skeleton of the original painting can be reproduced on the screen, and this method is efficient when a large number of paintings are to be produced.

A new colorless and transparent anodic oxide film is formed on the exposed aluminum surface obtained by the above treatment. If you want the entire ground color to be a certain color, such as the background, you can dye it by dipping it in a water-based dye.

The film is completely dried without sealing, and a mount or the like is sandwiched between each board to prevent moisture from entering.

(4) Fourth step: Hand over the art supplies prepared in the third step to the artist. iiU! Paint on one side using oil-based aluminum dye with a brush to complete the painting expression. At this time, screen l1. :
The dye applied with a brush penetrates into the countless pores created in the anodic oxide film. In this state, it is necessary to apply multiple coats of dye to form a pore coating, or to adjust the density of the dye that has penetrated.
It is also possible to reduce the color by 11 or to remove the color using a solvent or a decolorizing acid solution. Once the drawing is completed, the artist will have the artist write the signature and edition number in the designated area according to the customary practice of printmaking.

(5) Fifth step: 1 colored art supplies returned from the artist.
The sheets are sealed to fix the dye. The aluminum print is completed by cleaning the surface and polishing it with a protective polish such as silicone. In cases where further ultraviolet resistance is required, such as when used outdoors, the inner surface may be further coated with a transparent protective coating to prevent ultraviolet rays. The print produced using the process shown in Figure 1 has been etched once except for the skeleton of the screen, so the skeleton becomes a relief, giving the screen a three-dimensional effect.

Next, FIG. 2 is an example of another process in which no etching technique is used to reproduce the screen skeleton.

The steps will be explained in order below with reference to FIG.

(1) First step: Until the anodized coating is applied to the material, the
As in the case of the figure, if the background color is required on the entire surface, the entire surface is immersed and colored with water-based dye. In other cases, it is not dyed and remains colorless and transparent, and the surface is covered with a photoresist film with the anodic oxide film left unsealed.

(2) Second step The first step is to extract and make a plate using a camera using photolithography technology to extract the skeleton from the original drawing or sketch by the two artists.
This is the same as the case shown in the figure. However, the skeletal image in this case is processed to become a positive image.

Furthermore, if gradation of gradation is required for drawing the skeleton, halftone printing can be used to adjust the gradation to various levels. There is a method that does not use photoengraving to further enhance the originality of the print.

This is a method in which an artist draws a skeleton image such as brush strokes and outlines using opaque ink that does not transmit light on a transparent acetate film, etc., and then uses this for direct contact exposure instead of a plate-making film. It is. It goes without saying that it is easier to express the artist's touch more directly in this way, but as a work, it is somewhat difficult to express the shading of the lines, and it is necessary to express it with the thickness of the lines, blurring of the brush, etc. .

(3) Third step: The art material treated in the first step and the body film made in the second step are overlapped and brought into close contact and exposed. During development, the photosensitive film that forms the framework of the painting is removed, exposing the first colorless and transparent anodic oxide film. When the art materials are washed and dried and an oil-based dye is applied, the skeleton of the picture is dyed.The third step is completed by removing the remaining photosensitive film with chemicals and washing with water. The difference between this stage of the work and the case in Figure 1 is that the skeleton remains unsealed and there is no etching process, so the screen remains completely flat.

The screen method can be used in the process shown in FIG. 2 as well as in the case shown in FIG. If you screen-print an image that will become the skeleton part and then screen print it directly onto the unsealed anodic oxide film using ink impregnated with aluminum dye, the dye in the ink will penetrate into the film and create an image of the skeleton part. is transferred onto an aluminum plate. This method is also suitable when a large number of sheets are to be produced.

(4) Fourth step: In the third step, the skeleton of the print is reproduced on the screen, and arbitrary colors are added to it using the artist's brushstrokes.The subsequent steps are the same as those shown in Figure 1.Figure 3 2 shows a reproduction of the frame of the print produced in the process shown in Figures 1 and 2, and is an example of a print that has just been colored by the artist, and has completed the third process at the factory.

Figure 4 shows the state of the print shown in Figure 3, which has been colored by the artist and completed. 1 in the figure is the drawing and outline part that was first reproduced industrially to form the skeleton of the print, and 2 and 3 show the parts painted with brushes in various colors. 4 is the white part of the screen that was expressed without brush painting, leaving the initial transparent semi-gloss anodic oxide film intact.

[Effects of the Invention] The print produced by the production method of the present invention has the following effects.

1. The prints produced by the present invention are crafts with high artistic value that meet all the requirements for original prints, and even when producing a large number of prints, the coloring is completed by the artist's brushstrokes on each print, so the coloring must be done strictly. No two are exactly alike, and there is very little chance of it being duplicated.

2. All processes that involve technicians other than the painter are industrially standardized, and there is no room for individuality other than the painter to enter, so the artist's artistic purity is maintained.

3. Artists can use the extracted skeleton drawings to produce multiple highly creative prints relatively easily and efficiently, and can also draw scenes with changing light rays and tones during the brush painting stage, making it possible to create scenes with varying light rays and tones, making it possible to create a variety of prints for the four seasons. It is also possible to compose a series of prints such as landscapes.

4. From an industrial standpoint, the finished print is anodized aluminum product, so it has excellent weather resistance and corrosion resistance, and is much less susceptible to discoloration and fading compared to ordinary prints, and has a high surface hardness, making it highly resistant. It has excellent abrasion resistance, is resistant to contamination, and even if it gets dirty, it can be easily cleaned and restored.

5. Taking advantage of the above advantages, 1iA has a large number of public access.
It is also suitable as a wall interior.

Also, the exhibition can be viewed in places where it is inappropriate to display ordinary prints, such as outdoors.

6. The mural created by the present invention is made by dyeing a transparent anodic oxide film on a metal base with multicolored bright dyes, and the screen has a transparency and metallic texture unique to the anodic oxide film dyeing, resembling a watercolor painting and even more so. You can obtain prints from a completely new field that emphasize modern sensibilities.

7. According to the method of the present invention, the prints can be produced relatively inexpensively compared to conventional original prints, and are easy to handle and store with little risk of staining or damage, so they are suitable as prints for general household collection.
