Method of improving performance printing flexographic printing plates

摘要

A method to adapt the shape of a Plurality of points of Relief Printing, created in a piece of Printing PhotoSensitive tosca during a Manufacturing process of plates,Understanding this piece Rough Printing PhotoSensitive Layer disposed on at least a photocurable Layer ReinforcementThe Method comprises the steps of: a) at least one selectively expose the photocurable Layer to Actinic Radiation Source.To Crosslink and cure selectively at least a photocurable Layer; and (b) disclose the Rough piece of Printing PhotoSensitive Exposed, to reveal the relief Image in the sameUnderstanding the relief Image printing the Plurality of points in Relief Actinic Radiation Source; where the Joint comprises a Matrix type Light LED UVThat includes at least four rows, and the use of the Matrix of Joint type Light UV LED Printing Embossed points that have at least one Geometric Feature.Selected from the group consisting of a Top Surface flatness of the desired points of Relief Printing, a desired angle of Edge points of Relief printing.A desired Sharpness and Edge points of Relief Printing, where the rows Alternate UV LED Lights, the Joint Matrix type Light LED UVHave different Peak Wavelengths and operate at Wavelengths in the range of 360 nm to 420 nm, and where at least one photocurable Layer comprises a Photoinitiator,Where such Photoinitiator has a UV - vis Absorption peak in the Wavelength range of Joint Operational type Light UV LED.
