摘要： Systems and processes for making a flexo plate, and plates made thereby. Non-printing indicia defined by areas of resence and absence of polymer in the plate floor are readable downstream of the washing or other non-cured-polymer-removal step but do not print in the printing step. The non-printing indicia may define a repeating pattern of alphanumeric characters, non-text graphics, or a combination thereof.

摘要： A process for mounting a printing plate on a carrier sheet, including disposing registration indicia on the plate, placing the carrier sheet on a cutting table of a cutting system, mounting the plate to the carrier sheet, detecting absolute coordinates of the registration indicia; and cutting the carrier sheet along a cut line having absolute coordinates generated based upon the detected absolute coordinates. A related system includes the cutting system with the cutting table, a camera for detecting the registration indicia, a processor, a cutter, a controller, and a computer memory programmed with instructions for instructing the controller to detect the indicia, calculate the absolute coordinates for the cut line based upon the detected absolute coordinates and stored relative coordinates for the cut line, and cutting the carrier sheet along the cut line. Computer readable media containing such programmed instructions is also disclosed.

摘要： Systems and processes for making a flexo plate, and plates made thereby. Non-printing indicia defined by areas of presence and absence of polymer in the plate floor created using microdots imaged during a LAMS layer imaging step are readable downstream of the washing or other non-cured-polymer-removal step but not to print in the printing step. The non-printing indicia may define a repeating pattern of alphanumeric characters, non-text graphics, or a combination thereof. A difference in growth of plate structures corresponding to different types of microdots may be used for characterizing processing conditions.

摘要： A photosensitive flexographic printing form, and process for manufacturing the same. The printing form includes a base, a first series of relief patterns having a first elevation with respect to the base in an image area of the base, and a second series of relief patterns having one or more elevations lower than the first elevation and located outside of the image area.

摘要： Apparatus and method for directly curing photopolymer printing plates, such as with UV radiation. Printing plates are cured directly by radiation, such as emitted from a high power UV laser beam. No LAMS layer or film bearing the image information is required on top of the polymer plate. The laser beam may be split into several individually-modulated beams by means of an Acousto Optical Deflector. Each individual beam is capable of curing pixels of the image that are to be transferred to the printing plate. Support shoulders for the printing details, formed by the pixels are determined by the caustic of the UV beam propagation.

摘要： An apparatus comprises: (a) a rotatable drum configured to have a UV-curable printing plate with an ablatable layer thereon, placed thereon; (b) at least one laser beam to image the plate on the drum by ablating some of the ablatable layer according to image data to form an imaged plate; (c) an unloading area onto which a plate is movable when unloaded; and (d) a plurality of UV LEDs configured to cure UV-curable material on at least an imaged portion of the plate during the imaging process, such that imaging of one part of the plate and curing of an imaged portion of the plate occur simultaneously. In another embodiment, the plurality of LEDs are to apply UV radiation to the back of the UV-curable plate or to both the front and back of the UV-curable plate during or after the unloading of the imaged plate.

摘要： A device and method are described for the easy and rapid loading and unloading of flexographic sleeves from flexographic processing machines. The device includes internal chucks that hold on to the end of a sleeve or sleeve adapter. The chucks are rotatably mounted within a flexographic processing machine to permit sleeve processing. In addition, the chucks may move to accommodate a large range of sleeve or adapter diameters and lengths. The method permits the loading and unloading of sleeves with a minimum amount of sleeve handling and without additional end pieces or adapters.

摘要： A cylindrically-shaped tube fitting over a cylindrically-shaped base body rotatable around an axis of rotation. The tube has a cylindrically-shaped inner surface defining a hollow region, a cylindrically-shaped outer surface, a first end, and a second end. The base body is arranged to fit either a sleeve or the tube. The outer surface includes vacuum grooves or a plate clamping system or both, and arranged to secure a flexible sheet of material around the outer surface of the tube.

摘要： A finished flexo plate with printing dots and non-printing indicia. The printing dots have an elevation above the plate floor sufficient to transfer ink to a substrate in a printing step, whereas the non-printing indicia are configured for persistent readability relative to the plate floor but have a height relative to the plate floor insufficient to transfer ink to the substrate in the printing step. The non-printing indicia define a pattern of alphanumeric characters, non-text graphics, or a combination thereof, and are disposed on the plate floor in the form of areas of presence and absence of polymer defined by structures formed of microdots, each microdot having an elevation relative to the plate floor lower than a printing height.
