Descripción de la invenciónDescription of the invention

Con el fin de alcanzar los objetivos y evitar los inconvenientes mencionados en los apartados anteriores, la invención propone un cilindro para decorar baldosas cerámicas que presenta como novedad el hecho de que se lleva a cabo la impresión de un material fotopolímero en el cual se invierte el proceso óptico de grabación habitual, obteniendo huecos que sean los receptores de la tinta a depositar en la baldosa, en lugar de los clásicos resaltes.In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a cylinder to decorate ceramic tiles that presents as a novelty the fact that printing is carried out of a photopolymer material in which the process is reversed optical recording usual, obtaining gaps that are ink receivers to deposit on the tile, instead of classic highlights.

Se invierten las zonas de incidencia de la luz sobre la lámina de fotopolímero, siendo en este caso el punto que recibirá la tinta, el que queda oculto a dicha incidencia de luz y por lo tanto no se endurece. Lo que supone que al someterse al revelado químico, el material es eliminado generando un hueco en dicho material fotopolimérico.Light incidence zones are reversed on the photopolymer sheet, in this case being the point that you will receive the ink, the one that is hidden from this incidence of light and Therefore it does not harden. Which means that by submitting to chemical development, the material is removed generating a gap in said photopolymeric material.

Por lo tanto el cilindro objeto de la invención comprende al menos una superficie elástica como los ya conocidos en la actualidad y se caracteriza porque sobre dicha superficie elástica se aplica una lámina de fotopolímero cuyos puntos receptores de tinta son huecos que se han obtenido por un revelado químico de aquellos puntos no impresionados por la luz.Therefore the cylinder object of the invention It comprises at least one elastic surface such as those already known in the present and it is characterized because on said surface elastic is applied a photopolymer sheet whose points ink receivers are gaps that have been obtained by a development chemical of those points not impressed by the light.

También se caracteriza porque la plantilla para la impresión por luz es un positivo del motivo decorativo, es decir, que no deja pasar la luz en los puntos receptores de tinta, a diferencia del proceso tradicional en flexografía, en el que la plantilla para la impresión por luz es un negativo del motivo decorativo, pues el punto de tinta es el que debe quedar impresionado por la luz en la lámina fotopolimérica.It is also characterized because the template for light printing is a positive decorative motif, it is say, that it does not let the light through the ink receiving points, unlike the traditional process in flexography, in which the Template for light printing is a negative reason decorative, because the ink point is the one that should remain impressed by the light on the photopolymer sheet.

A continuación para facilitar una mejor comprensión de esta memoria descriptiva y formando parte integrante de la misma, se acompañan unas figuras en las que con carácter ilustrativo y no limitativo se ha representado el objeto de la invención.Next to facilitate a better understanding of this descriptive report and being an integral part of the same, some figures are accompanied in which with character illustrative and not limiting the object of the invention.

Descripción de la forma de realización preferidaDescription of the preferred embodiment

Considerando la numeración adoptada en las figuras, el cilindro para decorar baldosas cerámicas incorpora entre sus elementos un cuerpo elástico cilíndrico-tubular 1, sobre cuya superficie exterior se aplica y fija una lámina de fotopolímero 2 que incorpora puntos rehundidos receptores de tinta 3 obtenidos mediante un revelado químico de aquellos puntos no impresionados por la luz 4.Considering the numbering adopted in the figures, the cylinder to decorate ceramic tiles incorporates between  its elements a cylindrical-tubular elastic body 1, on whose outer surface a sheet of photopolymer 2 incorporating recessed ink receptor dots 3 obtained by chemical development of those points not impressed by the light 4.

Por otro lado, la plantilla o negativo 5 para la impresión por luz es un positivo del motivo decorativo, es decir, que al proyectar la luz sobre la lámina de fotopolímero con interposición de la respectiva plantilla habrá zonas ensombrecidas debido a la interposición de la plantilla correspondiendo dichas zonas ensombrecidas precisamente con las zonas o puntos receptores de tinta.On the other hand, the template or negative 5 for the  Light printing is a positive decorative motif, that is, that when projecting light on the photopolymer sheet with interposition of the respective template there will be shadowed areas due to the interposition of the template corresponding said shadowed areas precisely with the receiving zones or points from ink.

Así pues, esto quiere decir que la plantilla 5 no deja pasar la luz en los puntos receptores de tinta, a diferencia del proceso tradicional en flexografía en el que la plantilla para la impresión por luz es un negativo del motivo decorativo, pues el punto de tinta es el que se debe quedar impresionado por la luz en la lámina fotopolimérica al contrario de lo que ocurre en la presente invención.So, this means that template 5 does not let light through the ink receiving points, to difference from the traditional process in flexography in which the Template for light printing is a negative reason decorative, because the ink point is the one that should remain impressed by the light on the photopolymeric sheet as opposed to what happens in the present invention.
