摘要： Systems and methods for making a flexo plate, and plates, machines, readers, and computer readable media for use therewith. In the system, a plurality of processing machines, each configured to perform one or more process steps in a workflow, includes a controller, a variable operating parameter controlled by the controller, and a reader configured to read machine-readable indicia on the flexo plate. The machine-readable indicia (e.g. bar code, RFID tag, text) is configured for persistent readability downstream of washing (and cutting) steps, without printing in the printing step. The indicia may embody information including at least a plate identifier and instructions corresponding to the at least one variable operating parameter for each of the processing machines or information corresponding to an address in computer storage where the information resides.

摘要： 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.

摘要： 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.

摘要： An apparatus for and a method of loading and unloading of plates to and from an imager. The apparatus includes a loading area holding one single or a plurality of plates and an unloading area holding a single plate, the areas arranged vertically. The plate includes ultraviolet curable material. The apparatus includes a control system configured when in operation to control the automated loading and unloading and the apparatus elements therefor. One fully automatic version includes automatic loading from a stack or set of plate magazines and in the case that the plate includes a protective sheet thereon, includes removing the protective sheet from the plate. Some versions also include one or more ultraviolet sources to irradiate the flexographic plates with ultraviolet radiation during the automated loading and/or unloading. The ultraviolet sources are controlled by the same control system.

摘要： 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.

摘要： 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.
