摘要： An apparatus for curing a printing plate made of or having photo-curable material, a method of curing such a printing plate, and a printing plate cured by the method. One embodiment of the method includes curing a printing plate made of or having photo-curable material thereon. The method includes producing light energy on part of the printing plate using a light exposure unit, including relative motion between the light energy and the plate in a transverse direction at a changeable period of repetition, such that curing can produce printing features on the plate that can be switched to have either flat tops or round tops according to the period of repetition.

摘要： The present application concerns a method of curing a photo-curable printing plate, comprising: (i) providing a light exposure unit comprising a light tunnel having a cross-section and a plurality of walls (303) each wall having a reflective inner surface (311); (ii) placing a photo-curable printing plate near the light exposure unit having a length, a cross-section, and a pair of ends being a source end and a plate end, the plate having a printing surface placed with the printing surface closer to the plate end than to the source end with the printing plate substantially parallel to the cross-section of the light exposure unit; (iii) producing light radiation by a light source (301) located at or near one end, called the source end of the light tunnel to the inside of the light tunnel towards the other end of the light tunnel, called the plate end, including towards the reflective inner surfaces (311) of the walls (303); and (iv) operating the light source to cure the plate material by applying light radiation for a time sufficient for curing; wherein the cross-section of said light tunnel is polygonal like a kaleidoscope and has at least four of said walls (303), wherein said at least four walls (303) consist of pairs of walls (303), each of said pairs of walls (303) having a first wall and a second wall opposite to and parallel to said first wall, said reflective inner surface (311) of said first wall (303) facing said reflective inner surface (311) of said second wall (303).

摘要： A method of imaging a printing plate and curing the printing plate made of or having photocurable material that includes an ablatable mask. In one embodiment, the method comprises imaging the ablatable mask with a first portion of imaging data to produce a partially imaged uncured plate. Imaging data includes the first portion and a second portion of imaging data. The method includes curing the partially imaged uncured plate using UV with a first set of parameters to produce a partially cured plate with a partially ablated mask thereon, the curing arranged for producing flat tops, imaging the partially ablated mask on the partially cured plate with the second portion of imaging data to produce a totally imaged partially cured plate, and curing the totally imaged partially cured plate with a second set of one or more curing parameters to produce a totally cured plate to produce round tops.
