<p>The present invention relates to a method for providing flexographic plates, particularly for flexographic printing systems, comprising the following steps:
- first surface coating of a digital photopolymer plate (1) with a layer of protective material (2) that is impermeable to ultraviolet rays,
- ablating by means of a laser device (3) according to a preset graphic element the digital photopolymer plate (1) in order to remove the layer of protective material (2) in a manner that corresponds to the print points that define said graphic element,
- exposing, by means of one or more light sources (8), the digital photopolymer plate (1) for its polymerization in a manner that corresponds to the previously ablated regions (16),
- washing the polymerized digital photopolymer plate (1) for removal of the non-ablated regions (11) of the digital photopolymer plate (1),
- finishing the digital photopolymer plate (1) by means of an exposure to ultraviolet rays to complete the polymerization of the digital photopolymer plate (1).
In the exposure step the digital photopolymer plate (1) is exposed to a light source (8) adapted to generate ultraviolet light at least of the direct type by means of a photoexposure device (50).</p> |
