    Abstract: A method of making a relief image printing element from a photosensitive printing blank is provided. A photosensitive printing blank with a laser ablatable layer disposed on at least one photocurable layer is ablated with a laser to create an in situ mask. The printing blank is then exposed to at least one source of actinic radiation through the in situ mask to selectively cross link and cure portions of the photocurable layer. Diffusion of air into the at least one photocurable layer is limited during the exposing step and preferably at least one of the type, power and incident angle of illumination of the at least one source of actinic radiation is altered during the exposure step. The resulting relief image comprises a plurality of dots and a dot shape of the plurality of dots that provide optimal print performance on various substrates, including corrugated board.

    Abstract: A method of selectively exposing a liquid photopolymer printing blank to actinic radiation to create a relief image printing plate and a liquid platemaking exposure system. The method includes: (1) positioning a programmable screen programmed with an image file of a desired image between the top glass and an upper source of actinic radiation; (2) exposing the layer of liquid photopolymer to actinic radiation from the upper source of actinic radiation through the programmable screen to crosslink and cure at least a portion of the liquid photopolymer adjacent to the backing sheet and create a floor layer therein; and (3) imagewise exposing the layer of liquid photopolymer to actinic radiation from a lower source of actinic radiation through a negative of the relief image to crosslink and cure selective portions of the liquid photopolymer on the floor layer and create the relief image therein.

    Abstract: On a printing relief plate, which is produced by a printing relief plate producing apparatus and a printing relief plate producing method, convexities and detecting portions are set to be lower than a solid area of the printing relief plate. In the event that a detecting portion image and a solid area image are printed on a print medium using the printing relief plate by a printing apparatus and by carrying out a printing method, in a printing pressure determining apparatus and a printing pressure determining method, it is determined whether a printing pressure is an appropriate printing pressure or not by comparing an optical density of the detecting portion image and an optical density of the solid area image.
