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.The template for light printing is a positive of the decorative motif, that is, that does not let the light pass at the ink receiving points, unlike the process traditional in flexography, in which the template for the Light printing is a negative of the decorative motif, as the ink point is the one that should be impressed by the light in the photopolymer sheet.

Se caracteriza porque los puntos receptores de la tinta distribuidos en la lámina de fotopolímero comprenden unos huecos con una superficie curvada, presentando esencialmente una configuración en forma de porción esférica y más concretamente de forma semiesférica.It is characterized because the receptor points of The ink distributed in the photopolymer sheet comprises some gaps with a curved surface, essentially presenting a configuration in the form of a spherical portion and more specifically of hemispherical shape.

El nuevo sistema de decoración rotativa con la incorporación de los característicos huecos receptores de tinta presenta las siguientes ventajas:The new rotary decoration system with the incorporation of the characteristic ink receiver gaps It has the following advantages:

--
Permite reproducir diseños sobre piezas cerámicas a una resolución de cincuenta puntos por cm y conseguir efectos de acabado más nítidos gracias a una perfecta forma de las cavidades o puntos de sus rodillos y una óptima descarga de tinta.It allows to reproduce designs on pieces ceramics at a resolution of fifty points per cm and get sharper finishing effects thanks to a perfect shape of the cavities or points of its rollers and an optimal discharge of ink.

--
Es un sistema integrado que genera ahorros de costes tanto a fabricante como a proveedores de diseño.Is a integrated system that generates cost savings to both manufacturer As to design suppliers.

--
Facilita y acorta el proceso de desarrollo de nuevos productos y prolonga la duración de los consumibles de decoración.Facilitates and shortens the process of development of new products and prolongs the duration of decoration supplies.

--
A medida que aumenta la resolución de impresión disminuye el diámetro y profundidad de los huecos semiesféricos.TO as the print resolution increases the diameter decreases and depth of the hemispherical holes.

La forma semiesférica perfecta y estable de los huecos así como su profundidad variable aseguran la total y fácil descarga de la tinta alojados en su interior, incluso a altas resoluciones, cubriéndose por tanto todos los campos en el diseño de los dibujos de las piezas cerámicas.The perfect and stable hemispherical shape of the gaps as well as its variable depth ensure total and easy ink discharge housed inside, even at high resolutions, thus covering all fields in the design of the drawings of the ceramic pieces.

No se van acumulando en los huecos restos tras cada deposición que puedan generar una disminución progresiva de la cantidad de tinta descargada, al contrario de lo que ocurre convencionalmente algunas veces.Remains are not accumulating in the hollows after each deposition that can generate a progressive decrease of the amount of ink discharged, contrary to what happens conventionally sometimes.

El resultado son productos de gran calidad estética, con una superior definición de líneas y contraste cromático.The result is high quality products aesthetic, with superior definition of lines and contrast chromatic.

Es posible reproducir diseños sobre piezas cerámicas en producción industrial continua a una resolución de 50 puntos por cm tal como se ha referido anteriormente, manteniendo una estabilidad tonal, sin la aparición del efecto "doble impresión" y sin tener que modificar parámetros, como por ejemplo la velocidad de producción y la viscosidad de las tintas serigráficas.It is possible to reproduce designs on pieces ceramics in continuous industrial production at a resolution of 50 points per cm as mentioned above, keeping a tonal stability, without the appearance of the double effect printing "and without having to modify parameters, as per example the production speed and viscosity of the inks screen printing

Con las mejoras de la invención se obtienen además unos efectos de acabado más nítidos. La razón no es otra que la forma semiesférica de las gotas depositadas por los puntos que evita la aparición de imperfecciones como la falta de nitidez o emborronamiento de serigrafías.With the improvements of the invention are obtained also sharper finishing effects. The reason is not another that the hemispherical shape of the drops deposited by the points that prevents the appearance of imperfections such as lack of sharpness or smudging of serigraphs.

La mejoras permiten también aplicar metalizados, texturizados, blancos o protecciones a lineaturas de hasta veinte puntos por cm depositando una capa de tinta de gran espesor y consiguiendo un acabado de mayor nitidez.The improvements also allow applying metallic,  textured, white or lineature protections of up to twenty dots per cm by depositing a layer of thick ink and getting a sharper finish.
