Abstract: An apparatus for exposing a printing plate including at least a front source array of LEDs that emits a radiation field incident on the front side of the plate and a back source array of LEDs that emits a radiation field incident on the back side of the plate. A controller connected to the front source and the back source causes movement of at least the front radiation field relative to the plate fixed on a substrate that receives the printing plate in a fixed configuration between the front source and the back source. The apparatus commences a first exposure step of one side of the plate with one of the sources and then a second exposure step of the opposite side of the plate with the other source, imposing a user-definable time delay (t) between commencing the first exposure step and commencing the second exposure step.

Abstract: Apparatus, method, and system for exposing a photosensitive printing plate to radiation, including a plurality of LED point sources configured to emit UV light. The plurality of LED point sources in at least one of a front side set or back side set are controllable in subsets smaller than an entirety of the collective irradiation field corresponding to the respective set. A holder receives the printing plate in a stationary position to receive incident radiation and a controller is configured to control the plurality of LED source subsets. A first LED point source subset is configured to be controlled at a first intensity differing by a factor relative to a second intensity of a second LED point source subset to give the radiation emitted by the respective set an intended degree of homogeneity.

Abstract: Systems and methods for curing a photopolymer printing plates. A radiation source, such as an UV LED source having a radiation-emitting lateral dimension in a range 10-60 cm, is spaced from a substrate that holds the printing plate. The source and substrate are configured to move relative to one another in a movement direction that defines a leading edge of the radiation source and a trailing edge of the radiation source. A cooling air handling system directs a volume of cooling air into the gap between the radiation source and the printing plate in a direction from the trailing edge to the leading edge. The cooling air handling system may have one or more outlets attached at least one edge of the source, may be configured to only direct air from the trailing edge to the leading edge, or a combination thereof.

Abstract: Methods, systems, and non-transitory memory media embodying computer readable instructions for minimizing voids in front of a trailing edge of a solid rendition or linework print region printed using a photocurable flexographic printing plate having a printing surface corresponding to information in an image file. At least one solid rendition or linework image region corresponding to the solid rendition or linework print region has a pattern of “on” and “off” single pixels that correspond to openings formed by an imager in a mask layer of the plate. Micro-screen openings in an edge region of the solid rendition or linework mask region are imaged with a different size than micro-screen openings in a center region of the solid rendition or linework mask region.

Abstract: The overall mechanism for creating the exposure may comprise a table having an outer frame 1110 that holds a transparent (e.g. glass) inner portion 1112. The upper 1120 and lower 1122 linear radiation sources (e.g. banks of LED point sources, optionally mounted inside a reflective housing) are mounted on a gantry system or carriage 1130. The radiation sources are connected to a power source, such as an electrical power cord having sufficient slack to extend the full range of motion of the carriage. Tracks (not shown) disposed on the outer frame portion provide a defined path for the gantry system or carriage to traverse. The carriage may be moved on the tracks by any drive mechanism known in the art (also coupled to the power supply and the controller), including a chain drive, a spindle drive, gear drive, or the like. The drive mechanism for the carriage may comprise one or more components mounted within the carriage, one or more components fixed to the table, or a combination thereof.

Abstract: Systems and methods for exposing photopolymer printing plate material located within a target area having first and second dimensions. A light source having LEDs arrayed coextensive with the first dimension moves relative to the second dimension, and emits different light intensities over the target area in at least one of the first dimension or the second dimension. The systems and methods may be used to determine exposure parameters for curing a selected plate by causing different sample units to receive different amounts of total energy exposure, exposure energy per exposure step, or a combination thereof, and visually evaluating each sample unit against a reference plate of the same type and thickness. The sample unit embodying a minimum acceptable total exposure energy and a maximum acceptable exposure energy per exposure step is then identified.

Abstract: A method and apparatus to expose photosensitive printing plates with a predetermined radiation density from the main side (top) and a predetermined radiation density from the back side (bottom). The method comprises executing the main exposure with a time delay after the back exposure. The time delay between back exposure and main exposure is optimized to create smaller stable single dot elements on the photosensitive printing plate after processing and smaller single element dot sizes printed on the print substrate. The plate floor may be adjusted by performing a back-side-only exposure prior to executing the combined back and main exposure with the time delay.
