Description

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La presente invención se puede incluir en el campo tecnológico de la elaboración y reproducción de matrices con motivos artísticos. Más concretamente, el objeto de la presente invención se refiere a un procedimiento para la 10 obtención de una matriz de una obra gráfica, así como la reproducción seriada de dicha obra artística que permite reproducibilidad indefinida sin desgaste de la matriz. The present invention can be included in the technological field of the elaboration and reproduction of matrices with artistic motives. More specifically, the object of the present invention relates to a procedure for obtaining a matrix of a graphic work, as well as serial reproduction of said artistic work that allows indefinite reproducibility without wear of the matrix.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

15 Son conocidas diversas técnicas para la obtención de reproducciones seriadas de obras gráficas. 15 Various techniques are known for obtaining serial reproductions of graphic works.

Una de dichas técnicas es la litografía, en la que se dibuja con material graso un motivo sobre piedra caliza. Una vez secado el motivo, se recubre la superficie de la piedra con una fina película de goma arábiga y ácido nítrico, para fijar químicamente en la piedra las zonas dibujadas y las que no lo están. A continuación, se moja la piedra con agua. 20 Después, con la ayuda de un rodillo, se entinta la piedra de forma que la tinta nada más quedará adherida en las zonas que previamente han estado tratadas con materia grasa. Posteriormente se humedece la piedra, de modo que el agua es repelida por el material graso y queda depositada solamente en las partes de la piedra que no han sido pintadas con el material graso. A continuación, se aplica tinta a la piedra, donde la tinta es absorbida por el material graso y repelida por el agua, de tal manera que la parte pintada queda entintada. Por último, una vez secada la tinta, One of these techniques is lithography, in which a motif on limestone is drawn with fatty material. Once the motif has dried, the surface of the stone is covered with a thin film of gum arabic and nitric acid, to chemically fix the drawn areas and those that are not. Then the stone is wetted with water. 20 Then, with the help of a roller, the stone is inked so that the ink will only adhere to the areas that have previously been treated with grease. Subsequently the stone is moistened, so that the water is repelled by the fatty material and is deposited only in the parts of the stone that have not been painted with the fatty material. Next, ink is applied to the stone, where the ink is absorbed by the fatty material and repelled by the water, so that the painted part is inked. Finally, once the ink has dried,

25 se presiona, mediante una prensa litográfica, la piedra contra un papel de impresión para obtener la reproducción de la obra gráfica. 25, by means of a lithographic press, the stone is pressed against a printing paper to obtain the reproduction of the graphic work.

La litografía tiene, entre otros, los siguientes inconvenientes: Lithography has, among others, the following disadvantages:

--
permite un número limitado de reproducciones, debido al desgaste de la matriz; e  allows a limited number of reproductions, due to matrix wear; and

30 - implica el empleo de productos químicos cuya disponibilidad es limitada y cuyo precio es relativamente elevado. 30 - involves the use of chemicals whose availability is limited and whose price is relatively high.

DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION

35 La presente invención resuelve los inconvenientes mencionados, por medio de un procedimiento para la obtención de una obra gráfica a partir de una matriz de lámina translúcida de pergamino. The present invention solves the aforementioned drawbacks, by means of a method for obtaining a graphic work from a translucent sheet of parchment matrix.

La invención comprende un primer paso de generar un motivo gráfico sobre el pergamino, mediante la aplicación, empleando cualquier medio adecuado de que se disponga (tales como plumilla, pincel, chorro de tinta, etc.) de una 40 emulsión que comprende al menos un tinte con carácter hidrófilo y al menos una sustancia con carácter hidrófobo. The invention comprises a first step of generating a graphic motif on the parchment, by application, using any suitable means available (such as pen, brush, inkjet, etc.) of an emulsion comprising at least one dye with hydrophilic character and at least one substance with hydrophobic character.

De manera preferente, el tinte con carácter hidrófilo comprende tinta china, que puede ser negra o coloreada (por medio de pigmentos añadidos). De manera preferente, la sustancia con carácter hidrófobo es una disolución que comprende resina acrílica disuelta en una mezcla de aguarrás y gasolina blanca. Preferably, the hydrophilic dye comprises Chinese ink, which can be black or colored (by means of added pigments). Preferably, the hydrophobic substance is a solution comprising acrylic resin dissolved in a mixture of turpentine and white gasoline.

45 La disolución de resina acrílica en gasolina blanca y aguarrás está comercialmente disponible para su empleo como barniz. De la proporción de tinta china respecto de la disolución depende el tono más o menos vivo del color y su transparencia, como se explicará más adelante. Una proporción adecuada puede estar en torno a dos partes en volumen de tinta china por una de disolución. 45 The solution of acrylic resin in white gasoline and turpentine is commercially available for use as a varnish. The more or less vivid color tone and its transparency depend on the proportion of Chinese ink in relation to the solution, as will be explained later. A suitable proportion may be around two parts by volume of Chinese ink per one of dissolution.

50 La impregnación del pergamino con la emulsión sucede porque el tinte tiende a penetrar en el pergamino debido a su carácter hidrófilo, mientras que la sustancia hidrófuga tiende a retardar la penetración del tinte. Por ello, la cantidad de tinte que penetra en el pergamino se controla en primera instancia con el tiempo durante el cual se deja penetrar la emulsión. 50 The impregnation of the parchment with the emulsion occurs because the dye tends to penetrate the parchment due to its hydrophilic character, while the water-repellent substance tends to retard the penetration of the dye. Therefore, the amount of dye that penetrates the parchment is controlled in the first instance with the time during which the emulsion is allowed to penetrate.

55 La invención comprende un segundo paso de retirar la emulsión sobrante mediante un lavado con agua. El lavado puede realizarse sumergiendo en agua la parte del pergamino que se desea lavar, dejando que el agua se lleve la parte sobrante de la emulsión. Sin embargo, de manera preferente, el lavado se realiza dirigiendo uno o varios chorros de agua sobre la zona del pergamino. The invention comprises a second step of removing the excess emulsion by washing with water. The washing can be done by immersing the part of the parchment to be washed in water, allowing the water to take away the remaining part of the emulsion. However, preferably, washing is done by directing one or several jets of water over the parchment area.

60 La lámina de pergamino empleada es translúcida, de manera que, para conseguir diferentes efectos asociados a un mismo tono de tinta, se pueden efectuar diversos lavados sucesivos. De este modo, las zonas sometidas a un lavado más intensivo se muestran menos opacas, más transparentes. 60 The parchment sheet used is translucent, so that, in order to achieve different effects associated with the same ink shade, several successive washes can be performed. In this way, the areas undergoing more intensive washing are less opaque, more transparent.

Puesto que el tinte queda absorbido por el pergamino, las partes coloreadas y las partes no coloreadas del pergamino están en el mismo nivel, produciéndose un efecto de esfumado. Posteriormente, una vez producido un secado, que se describirá más adelante, puede quedar una capa sólida de emulsión, que permite el retocado de la Since the dye is absorbed by the parchment, the colored parts and the non-colored parts of the parchment are on the same level, producing a fading effect. Subsequently, once a drying has occurred, which will be described later, a solid emulsion layer can be left, which allows the retouching of the

5 obra, eliminando con espátula o similar una porción que se desea retocar y volviendo a pintarla. 5 work, removing with a spatula or similar a portion that you want to touch up and repaint it.

La invención comprende un tercer paso de secado del agua de lavado, que puede hacerse dejando que la emulsión se seque sobre el pergamino o forzando dicho secado, empleando medios como prensas, papel secante o papel de arroz, por ejemplo. The invention comprises a third step of drying the washing water, which can be done by allowing the emulsion to dry on the parchment or forcing said drying, using means such as presses, blotting paper or rice paper, for example.

10 Llegados a este punto, la matriz de lámina de pergamino ya está elaborada. Seguidamente, para proceder a la duplicación del motivo artístico de la matriz, la invención comprende un cuarto paso que se trata de realizar una fotografía digital a dicha matriz, disponiendo la matriz sobre un material transparente, tal como cristal, y haciendo una fotografía, preferentemente con luz trasera, preferentemente luz natural. Finalmente, la fotografía es impresa sobre la 10 At this point, the parchment sheet matrix is already made. Next, in order to proceed with the duplication of the artistic motif of the matrix, the invention comprises a fourth step which is about taking a digital photograph of said matrix, arranging the matrix on a transparent material, such as glass, and making a photograph, preferably with rear light, preferably natural light. Finally, the photograph is printed on the

15 superficie deseada, obteniéndose una reproducción fiel del motivo de la matriz sin desgaste de dicha matriz. 15 desired surface, obtaining a faithful reproduction of the motif of the matrix without wear of said matrix.

El empleo de luz natural es preferible porque contiene el espectro completo de luz y proporciona efectos más vistosos. El empleo de luz trasera es preferible porque la lámina de pergamino es translúcida y la luz trasera proporciona un efecto vistoso de penetración en la tinta. The use of natural light is preferable because it contains the full spectrum of light and provides more colorful effects. The use of taillight is preferable because the parchment sheet is translucent and the taillight provides a colorful ink penetration effect.

20 La aplicación del procedimiento de la invención, combinada con los denominados copolímeros diblock con base de gel de sílice, proporciona una manera de recubrir artísticamente superficies tales como fachadas de edificios, dotándolas de un carácter autolimpiable, debido a que la obra artística dispuesta sobre dicha superficie se recubre con el polímero diblock, que presenta un carácter súper-hidrofóbico y súper-hidrofílico, repeliendo de manera The application of the process of the invention, combined with the so-called diblock copolymers based on silica gel, provides a way of artistically coating surfaces such as building facades, giving them a self-cleaning character, because the artistic work arranged on said surface is coated with diblock polymer, which has a super-hydrophobic and super-hydrophilic character, repelling so

25 extraordinaria casi cualquier tipo de suciedad ambiental, proporcionando una gran durabilidad a la obra artística. Usualmente se emplea una capa trasera directamente sobre la superficie, que actúa como soporte de impresión de la obra, y posteriormente se recubre con el copolímero, lo cual le confiere una gran durabilidad y unas necesidades de mantenimiento mínimas. 25 extraordinary almost any type of environmental dirt, providing great durability to the artistic work. Usually a back layer is used directly on the surface, which acts as a print support for the work, and is subsequently coated with the copolymer, which gives it great durability and minimal maintenance needs.

30 Mediante el empleo del procedimiento de la invención se posibilita la obtención de una obra artística gráfica mediante la elaboración de una matriz de lámina translúcida de pergamino y posterior fotografiado de dicha obra, para posteriormente imprimir digitalmente en un soporte deseado la fotografía con el motivo gráfico dispuesto en la matriz, sin deterioro de la matriz, lo que permite una reproducción de copias casi ilimitada. Through the use of the method of the invention it is possible to obtain a graphic artistic work by preparing a translucent sheet matrix of parchment and later photographed of said work, to subsequently digitally print on a desired support the photograph with the graphic motif arranged in the matrix, without deterioration of the matrix, which allows almost unlimited copy reproduction.
