Description

Procedimiento de impresión para capuchones de botella Printing procedure for bottle caps
MEMORIA DESCRIPTIVA OBJETO DE LA INVENCIÓNDESCRIPTIVE MEMORY OBJECT OF THE INVENTION
La presente solicitud de patente de invención tiene por objeto el registro de un procedimiento de impresión para capuchones de botella que incorpora notables innovaciones y ventajas frente a los procesos actualmente conocidos.The purpose of the present invention patent application is to register a printing procedure for bottle caps that incorporates notable innovations and advantages over the processes currently known.
Más concretamente, la invención hace referencia a un procedimiento de impresión para capuchones de botella, como aquellos empleados para cubrir en parte los tapones de corcho o plásticos utilizados en botellas de vino, agua, etc., en el que el capuchón consiste en un cuerpo laminar susceptible de ser enrollado en una etapa posterior y donde la impresión se realiza de forma digital . ANTECEDENTES DE LA INVENCIÓNMore specifically, the invention refers to a printing process for bottle caps, such as those used to partially cover the cork or plastic caps used in bottles of wine, water, etc., in which the cap consists of a body laminar capable of being rolled up at a later stage and where the printing is done digitally. BACKGROUND OF THE INVENTION
Es bien conocida desde hace unos años la impresión de capuchones, por ejemplo, aquellos que se disponen alrededor de un tapón en una botella de una bebida con el fin de aportar un elemento más estético al conjunto de la botella. Para llevar a cabo dicha impresión son conocidos diversos métodos, tales como por ejemplo la impresión por huecograbado, por flexografía o tampografía que han demostrado no ser del todo adecuados ya que no permiten obtener un efecto visual que sería deseable. Además, los procesos de huecograbado y flexografía requieren el uso de tintas con una base solvente, de tal modo que incide negativamente en la prevención de riesgos laborales así desde un punto de vista medioambiental por la emisión de compuestos orgánicos volátiles.It is well known for a few years the printing of caps, for example, those that are arranged around a stopper in a bottle of a drink in order to provide a more aesthetic element to the whole of the bottle. Various methods are known to carry out such printing, such as for example gravure printing, flexography or pad printing that have proved to be not entirely suitable since they do not allow obtaining a visual effect that would be desirable. In addition, gravure and flexography processes require the use of solvent-based inks, so that it negatively impacts the prevention of occupational hazards thus from an environmental point of view by the emission of volatile organic compounds.
Además, el diseño a imprimir se debe hacer por separación de colores planos, debiéndose elaborar un montaje por cada color, hecho que requiere un cilindro de impresión y un puesto de secado para cada uno de los colores, hecho que encarece notablemente el proceso de imprimación.In addition, the design to be printed must be done by separation of flat colors, one assembly must be prepared for each color, a fact that requires a printing cylinder and a drying station for each of the colors, a fact that significantly increases the priming process .
Otros inconvenientes no menos importante detectados en los procesos de impresión anteriores es el hecho de que presenta una gran dificultad en la operación de centraje entre las distintas capas de color, una difícil obtención de colores impresos superpuestos en otro color previamente impreso, así como una dificultad en el perfilado de los contornos de letras y logotipos así como una falta de definición. Otro aspecto no menos importante es el hecho de que una baja calidad en el acabado visual del capuchón puede repercutir negativamente en la decisión final del cliente en el momento de elegir la marca de una botella de bebida a comprar.Other disadvantages not less important detected in the previous printing processes is the fact that it presents a great difficulty in the operation of centering between the different layers of color, a difficult obtaining of printed colors superimposed on another previously printed color, as well as a difficulty in profiling the contours of letters and logos as well as a blur. Another aspect that is not less important is the fact that a low quality of the visual finish of the cap can have a negative impact on the final decision of the client when choosing the brand of a bottle of drink to buy.
Es por ello que existe la necesidad de encontrar nuevos métodos o procedimientos de impresión alternativos que permitan obtener un elevado grado de calidad de imagen en el capuchón para tapones de botella.That is why there is a need to find new alternative printing methods or procedures that allow obtaining a high degree of image quality in the cap for bottle caps.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La presente invención se ha desarrollado con el fin de proporcionar un procedimiento de impresión que resuelva los inconvenientes anteriormente mencionados, aportando además, otras ventajas adicionales que serán evidentes a partir de la descripción que se acompaña a continuación.The present invention has been developed in order to provide a printing method that resolves the aforementioned drawbacks, also providing other Additional advantages that will be apparent from the description that follows.
Es por lo tanto un objeto de la invención proporcionar un procedimiento de impresión para capuchones de botella, en el que el capuchón consiste en un cuerpo laminar susceptible de ser enrollado en una etapa posterior y se caracteriza esencialmente por el hecho de que la impresión de al menos una de las caras del cuerpo laminar se lleva a cabo mediante el uso de una máquina de impresión digital, en el que el diseño a imprimir sobre el cuerpo laminar es transferido desde un ordenador a la unidad de procesado de la máquina de impresión digital en una etapa de impresión digital .It is therefore an object of the invention to provide a printing method for bottle caps, in which the cap consists of a laminar body capable of being rolled at a later stage and is essentially characterized by the fact that the printing of less one of the faces of the laminar body is carried out through the use of a digital printing machine, in which the design to be printed on the laminar body is transferred from a computer to the processing unit of the digital printing machine in A stage of digital printing.
En el caso de que el cuerpo laminar del capuchón este hecho de material de aluminio virgen o similar, tal como, un material compuesto de Aluminio-Polietileno-Aluminio, previa a la etapa de imprimir digitalmente el cuerpo laminar, se aplica una capa de barniz deslizante al hacer pasar dicho cuerpo laminar a través de un rodillo giratorio. El barniz deslizante tiene una doble función: facilitar la expulsión del material en un punzón conformador cuando se fabrica la cápsula o capuchón y por otro lado facilitar la distribución posterior de los capuchones en líneas de embotellado. Después de aplicar la capa de barniz deslizante se aplica una capa de barniz de enganche al hacer pasar dicho cuerpo laminar a través de un rodillo giratorio, que tiene la función de mejorar en anclaje de las tintas aplicadas posteriormente en la impresión digital . En una alternativa en el caso de que el cuerpo laminar sea aluminio previamente tratado se aplica, previa a la etapa de imprimir digitalmente el cuerpo laminar, se aplica una capa de barniz de enganche al hacer pasar dicho cuerpo laminar a través de un rodillo giratorio. El tratamiento previo puede ser, por ejemplo, la aplicación de un adhesivo de fusión en caliente.In the event that the laminar body of the cap is made of virgin aluminum material or the like, such as an aluminum-Polyethylene-Aluminum composite material, prior to the stage of digitally printing the laminar body, a varnish layer is applied sliding by passing said sheet body through a rotating roller. The sliding varnish has a double function: to facilitate the expulsion of the material in a forming punch when the capsule or cap is manufactured and on the other hand to facilitate the subsequent distribution of the caps in bottling lines. After applying the sliding varnish layer, a coating varnish layer is applied by passing said laminar body through a rotating roller, which has the function of improving the anchorage of the inks subsequently applied in digital printing. In an alternative in the case that the laminar body is previously treated aluminum, prior to the step of digitally printing the laminar body, a coating of varnish is applied by passing said laminar body through a rotating roller. The pretreatment may be, for example, the application of a hot melt adhesive.
Preferentemente, el procedimiento puede comprender una etapa posterior a la etapa de imprimir digitalmente el cuerpo laminar de aplicar una sustancia estabilizante con una base de agua que incluye material surfuctante al hacer pasar dicho cuerpo laminar a través de un rodillo giratorio.Preferably, the method may comprise a stage subsequent to the stage of digitally printing the sheet body of applying a stabilizing substance with a water base that includes surfing material by passing said sheet body through a rotating roller.
Según otro aspecto de la invención, la sustancia estabilizante comprende un barniz que incluye el material surfuctante comprendido en un rango de concentración de 0,4-4% en peso, más preferentemente en un rango de concentración de 0,5-3% en peso.According to another aspect of the invention, the stabilizing substance comprises a varnish that includes the surfing material comprised in a concentration range of 0.4-4% by weight, more preferably in a concentration range of 0.5-3% by weight .
Preferentemente, la sustancia estabilizante comprende agua destilada en una proporción de 6-40% en peso, más preferentemente en un rango de 7-30% en peso. De acuerdo con otra característica de la invención, el cuerpo laminar pasa a través del rodillo giratorio con una velocidad comprendida entre 50 y 120 m/min.Preferably, the stabilizing substance comprises distilled water in a proportion of 6-40% by weight, more preferably in a range of 7-30% by weight. According to another characteristic of the invention, the laminar body passes through the rotating roller with a speed between 50 and 120 m / min.
Antes de la aplicación de la capa de barniz de enganche puede llevarse a cabo una etapa que consiste en un tratamiento de corona. Este tratamiento aporta una mejor adherencia del barniz de enganche al proporcionar al material una tensión superficial de entre 38 y 50 dynas/cm o mN/m, aplicándose dicho tratamiento sobre la cara de material sonde se aplica el barniz de enganche.Before the application of the coating varnish layer, a step consisting of a crown treatment can be carried out. This treatment provides a better adhesion of the hook varnish by providing the material with a surface tension of between 38 and 50 dynas / cm or mN / m, said treatment being applied on the face of material where the coupling varnish is applied.
Es también objeto de la presente invención proporcionar un método que permite impresiones respetuosas con el medio ambiente, una flexibilidad en el proceso de decoración de la lámina de material en lo que se refiere a ajustes rápidos sin la necesidad del empleo de útiles adicionales para la decoración o acabado final así como una no- limitación en el diseño de la decoración a obtener. Gracias a estas características, se obtiene un procedimiento novedoso que permite obtener una gran calidad visual en la impresión sobre la lámina que conforma un capuchón para botellas, permitiendo además pequeñas tiradas de diseños que presentan cierta dificultad hasta ahora por la complejidad en la decoración de las botellas de vino, cava, etc. y un uso más intenso de los colores obteniendo presentaciones que aporten un valor añadido al conjunto del envase.It is also the object of the present invention to provide a method that allows environmentally friendly prints, a flexibility in the process of decorating the sheet of material in terms of rapid adjustments without the need for additional decoration tools. or final finish as well as a non-limitation in the design of the decoration to be obtained. Thanks to these characteristics, a novel procedure is obtained that allows to obtain a great visual quality in the printing on the sheet that forms a cap for bottles, also allowing small runs of designs that present some difficulty so far due to the complexity in the decoration of the bottles of wine, cava, etc. and a more intense use of colors obtaining presentations that provide added value to the package as a whole.
Otras características y ventajas del procedimiento de impresión objeto de la presente invención resultarán evidentes a partir de la descripción de una realización preferida, pero no exclusiva, que se ilustra a modo de ejemplo no limitativo en los dibujos que se acompañan, en los cuales:Other features and advantages of the printing process object of the present invention will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTE En una realización preferida de la invención, se describe un procedimiento para la impresión de capuchones para ser colocados posteriormente en una botella, por ejemplo, de las utilizadas para el vino, agua, cava, etc., en el que el capuchón (10) consiste en un cuerpo laminar susceptible de ser enrollado en una etapa posterior para conformar el capuchón a colocar. En la figura 1 se ha mostrado el capuchón (10) en una condición final de fabricación.DESCRIPTION OF A PREFERRED EMBODIMENT In a preferred embodiment of the invention, a method for printing caps to be subsequently placed in a bottle is described, for example, those used for wine, water, champagne, etc., in which The cap (10) consists of a laminar body capable of being wound at a later stage to form the cap to be placed. Figure 1 shows the cap (10) in a final manufacturing condition.
Seguidamente se detalla las distintas etapas que se realizan en el procedimiento de impresión de forma digital haciendo referencia al esquema mostrado en la figura 2:The different steps that are performed in the digital printing process are detailed below, referring to the scheme shown in Figure 2:
Antes de realizar la impresión digital se realiza una etapa (1) de aplicación de una capa de barniz deslizante haciendo pasar el cuerpo laminar alargado (procedente de una bobina de alimentación) a través de un rodillo giratorio situado en una máquina de impresión convencional es decir, no digital (no representada) . Después de aplicar la capa de barniz deslizante, en otra etapa (2) se aplica una capa de barniz de enganche al hacer pasar dicho cuerpo laminar a través de un rodillo giratorio situado también en la misma máquina de impresión convencional. La impresión de al menos una de las caras del cuerpo laminar se lleva a cabo en otra etapa (3) mediante el uso de una máquina de impresión digital, en el que el diseño a imprimir sobre el cuerpo laminar es transferido desde un ordenador a la unidad de procesado de la máquina de impresión digital en una etapa de impresión digital (3) . Tras la etapa (3) de la impresión digital del cuerpo laminar se aplica una etapa posterior (4) que consiste en la aplicación de una sustancia estabilizante con una base de agua que incluye material surfuctante al hacer pasar dicho cuerpo laminar a través de un rodillo giratorio (no mostrado) . Dicho rodillo giratorio puede estar dispuesto en una máquina de impresión convencional, es decir, no digital que puede ser la misma o distinta a la utilizada en la etapa (1) .Before carrying out the digital printing, a step (1) of applying a sliding varnish layer is carried out by passing the elongated laminar body (from a feed reel) through a rotating roller located in a conventional printing machine that is to say , not digital (not shown). After applying the sliding varnish layer, in another stage (2) a coating varnish layer is applied by passing said laminar body through a rotating roller also located in the same conventional printing machine. The printing of at least one of the faces of the laminar body is carried out in another stage (3) by using a machine digital printing, in which the design to be printed on the laminar body is transferred from a computer to the processing unit of the digital printing machine in a digital printing stage (3). After the stage (3) of the digital printing of the laminar body, a subsequent stage (4) is applied, which consists in the application of a stabilizing substance with a water base that includes surfing material when passing said laminar body through a roller swivel (not shown). Said rotating roller can be arranged in a conventional printing machine, that is, non-digital that can be the same or different from that used in step (1).
Con referencia a la sustancia estabilizante comprende un barniz que incluye el material surfuctante que está comprendido en un rango de concentración de 0,4-4% en peso, más preferentemente en un rango de concentración de 0,5-3% en peso. La sustancia estabilizante comprende agua destilada en una proporción de 6-40% en peso, más preferentemente en un rango de 7-30% en peso. El cuerpo laminar pasa a través del rodillo giratorio con una velocidad comprendida entre 50 y 120 m/min.With reference to the stabilizing substance, it comprises a varnish that includes the surfing material that is in a concentration range of 0.4-4% by weight, more preferably in a concentration range of 0.5-3% by weight. The stabilizing substance comprises distilled water in a proportion of 6-40% by weight, more preferably in a range of 7-30% by weight. The laminar body passes through the rotating roller with a speed between 50 and 120 m / min.
Ventajosamente, antes de la aplicación de la capa de barniz de enganche en la etapa se lleva a cabo una etapa (5) que consiste en un tratamiento de corona que comporta las ventajas que se han expuesto anteriormente. El tratamiento corona consiste esencialmente en un proceso producido por un generador de alta tensión y frecuencia, que alimenta un rodillo metálico suspendido con toma de tierra. Este proceso puede realizarse mediante un rodillo recubierto con un aislante (poliéster, cerámica o un elastómero de silicona) . La corona se forma cuando se aplica un alto voltaje que provoca la ionización del aire formando un plasma que permite posteriormente la realización de modificaciones superficiales.Advantageously, prior to the application of the coating varnish layer in the stage, a stage (5) is carried out, which consists of a crown treatment that entails the advantages set forth above. Corona treatment consists essentially of a process produced by a generator of high voltage and frequency, which feeds a suspended metal grounded roller. This process can be done using a roller coated with an insulator (polyester, ceramic or a silicone elastomer). The crown is formed when a high voltage is applied that causes the ionization of the air forming a plasma that subsequently allows surface modifications.
Resultará obvio para cualquier experto en la materia que puede emplearse cualquier tipo conocido de máquina de impresión digital previamente adaptada y preparada disponible en el mercado, motivo por el cual no se va a entrar en mayor detalle en la máquina de impresión digital empleada en el procedimiento descrito en esta memoria.It will be obvious to any person skilled in the art that any known type of previously adapted and prepared digital printing machine available on the market can be used, which is why the digital printing machine used in the procedure will not be introduced in greater detail described in this report.
