Abstract
Un método para fabricar un elemento de impresión de imagen en relieve a partir de una pieza en bruto de impresión fotosensible, comprendiendo dicha hoja de impresión fotosensible una capa que puede cortarse por láser dispuesta sobre al menos una capa fotocurable, comprendiendo el método las etapas de: a) la ablación selectiva por láser de la capa que puede cortarse por láser para crear una máscara in situ y descubrir porciones de la capa fotocurable; b) exponer la pieza en bruto de impresión cortada por láser a al menos una fuente de radiación actínica a través de la máscara in situ para unir selectivamente y curar porciones de la capa fotocurable, donde la difusión de aire en la al menos una capa fotocurable se limita durante la etapa de exposición mediante un método seleccionado de al menos uno de entre: i) laminar una membrana de barrera a la máscara in situ y a cualquier porción descubierta de la capa fotocurable utilizando presión y/o calor antes de la etapa (b); y ii) recubrir la máscara in situ y cualquier porción descubierta de la capa fotocurable con una capa de aceite antes de la etapa (b): donde el coeficiente de difusión de oxígeno de la membrana de barrera y/o la capa de aceite es menor que 6,9 x 10-9 m2/seg.
Description
barrera comprende una película de polipropileno con una capa de fotopolímero curada sobre la misma y la capa de fotopolímero curado tiene un patrón topográfico explícito definido en ella. La textura o rugosidad de la superficie de la membrana de barrera se imprimirá en la superficie de la capa de fotopolímero (fotocurable) durante la etapa de laminación. En general, la rugosidad superficial a este respecto se puede medir usando un perfilómetro óptico
5 Veeco, modelo Wyko NT 3300 (Veeco Instruments, Plainville, NY).
En otra realización de la presente invención, la membrana de barrera comprende una película de nanotecnología lisa con una rugosidad de menos de 100 nm. En esta realización, la rugosidad superficial media de la plancha de impresión se puede controlar a menos de aproximadamente 100 nm.
10 La capa de barrera se lamina a la superficie de la plancha de impresión usando presión y/o calor en un proceso de laminación típico.
En otra realización, la placa de impresión puede estar cubierta con una capa líquida de aceite, antes de la etapa de
15 exposición, y el aceite puede ser claro o teñido. El aceite aquí sirve como otra forma de una membrana de barrera. Al igual que con la membrana de barrera sólida, es importante que el aceite utilizado sea ópticamente transparente a la radiación actínica utilizada para exponer la capa fotocurable. La transparencia óptica de la capa de aceite es preferentemente al menos 50 %, lo más preferentemente al menos 75 %. La capa de aceite también debe ser capaz de inhibir sustancialmente la difusión de oxígeno en la capa fotocurable con un coeficiente de difusión de oxígeno
20 como se ha indicado anteriormente. El aceite también debe ser lo suficientemente viscoso como para permanecer en su lugar durante el procesamiento. Los inventores de la presente invención han determinado que una capa de aceite de 1 μm a 100 μm de espesor que comprende cualquiera de los siguientes aceites cumplirá los criterios anteriores: aceites de hidrocarburo parafínicos o nafténicos, aceites de silicona y aceites de base vegetal. El aceite se debe esparcir sobre la superficie del elemento de impresión después de que se cree la máscara in situ, pero
25 antes de que la pieza en bruto de impresión esté expuesta a radiación actínica.
Después de que la pieza en bruto de impresión fotosensible esté expuesta a radiación actínica como se describe en la presente memoria, la pieza en bruto de impresión se desarrolla para revelar la imagen de relieve en ella. El desarrollo puede conseguirse mediante diversos métodos, incluyendo el desarrollo del agua, el desarrollo del
30 disolvente y el desarrollo térmico, a modo de ejemplo y no de limitación.
Finalmente, el elemento de impresión de imagen en relieve se monta en un cilindro de impresión de una prensa de impresión y se inicia la impresión.
