摘要： A method of exposing imaging data (542) onto a sensitized medium (550) including exposing K sets (380, 480) of N of tracks (1, 2, 3, 4) onto the medium according to a corresponding part of imaging data, each successive set being a pixel distance apart in a fast scan direction (301, 401). The method further includes exposing L sets (390, 490) of N tracks onto the medium with an offset of M pixels in a slow scan direction (302, 402) substantially perpendicular to the fast scan direction, according to a second corresponding part of imaging data. The method includes repeating alternately exposing K sets and L sets of N tracks until the complete medium is exposed along the fast scan direction. During or after the alternately exposing K sets and L sets, there is progression in the slow scan direction such that after exposing the complete length of N tracks of exposed pixels, the next N tracks match along the medium at the start of the next N tracks.

摘要： A method includes exposing a plate on a support surface (103) of an imager using one or more laser beams, the exposing while there is a metallic screen (301) structure located on the support surface (103) between the plate and the support surface (103) such that the amount of back-reflected radiation is reduced compared to the plate being placed directly on the support structure with no screen (301) between the plate and support surface. An apparatus includes the combination of a base material having the support surface and the metallic screen structure thereon.

摘要： The present invention concerns a method of curing a digital printing plate made of or having photo-curable material, e.g. ultraviolet-curable material thereon, the method comprising:
producing light energy at a wavelength or wavelengths suitable for curing in part the photo-curable material on the printing plate using a light exposure capable of generating at least a first illumination intensity and a second illumination intensity, the second illumination intensity being higher than the first illumination intensity; and
curing in part the photo-curable material by the first illumination intensity or the second illumination intensity,
such that curing can produce printing features on the plate to have flat tops at the second illumination intensity or round tops at the first illumination intensity according to the illumination intensity output by the light exposure unit.

摘要： A UV exposure apparatus and method for curing a printing plate. A linear front exposure head is configured to emit a collective irradiation field toward a front side of a plate disposed on a substrate, and is configured to move relative to the plate. The linear front exposure head includes a plurality of front UV LED radiation point sources arranged in a plurality of independently controllable linear subgroups, each configured to emit a component irradiation field covering a component area coextensive with the first dimension of the plate, non-coextensive with the second dimension of the plate, and less than the collective area of the collective irradiation field. A controller is configured to control exposure of the plate using the movement speed, selective activation and deactivation of the linear subgroups, or a combination thereof to cause the plate to receive an amount of total front exposure energy.

摘要： An aspect relates to a process for exposing a printing plate comprising a photosensitive polymer activated by exposure to radiation, the printing plate having a non-printing back side and a printing front side with a mask for defining an image to be printed, the process comprising the sequential steps of:
(a) commencing irradiating the back side of the printing plate;
(b) automatically imposing a precisely defined time delay; and
(c) immediately after the time delay elapses, commencing irradiating the front side of the printing plate, without exposing any specific coordinate of the printing plate to both front side and back side irradiation simultaneously.

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.
