Abstract:
A method of making a flexographic printing forme comprising the steps of: (1) providing a flexographic support; (2) applying a powder layer on said support; (3) imagewise jetting a curable composition on said powder layer; (4) at least partially curing said jetted curable composition; (5) repeating steps (2) to (4) until the total thickness of said powder layers is greater than 100 µm. (6) removal of the powder not embedded in the imagewise jetted and at least partially cured composition; (7) optionally overall post curing.
Abstract:
A method of making a flexographic printing forme precursor for laser engraving comprising the steps of: (i) providing at least one layer of a curable composition on a substrate; (ii) curing said at least one layer;
characterized in that the curable composition forming an outermost layer of said precursor comprises at least 0.5 % by weight relative to the total weight of said composition forming the outermost layer of an organo-silicon compound, said organo-silicon compound comprising at least one polymerizable group.
Abstract:
A method of making a flexographic printing sleeve forme comprising the steps of: (i) formation of a sleeve body by providing one or more at least partially cured uniform layers on a sleeve carrier; (ii) formation of a relief image on said sleeve body by imagewise jetting a curable jetting fluid; (iii) optionally overall post-curing;
characterized in that between formation of the sleeve body and formation of the relief image no polishing or grinding is performed.
