  • Publication number: 20210394506
    Abstract: A flexographic printing system prints image patterns including one or more uniform image regions on a substrate. A flexographic printing plate includes a pattern of raised features for transferring ink to the substrate in accordance with the image pattern. An anilox roller having a plurality of anilox cells is configured to transfer ink to the flexographic printing plate. Uniform image regions of the flexographic printing plate corresponding to the uniform image regions of the image pattern include a pattern of raised feature shapes positioned in a pattern of pseudo-random feature locations. An average spacing between the raised feature shapes in the uniform image regions is less than an anilox cell size such that a plurality of the raised feature shapes receive ink from a single anilox cell of the anilox roller.

  • Publication number: 20210397095
    Abstract: A method for fabricating a flexographic printing plate for printing image patterns including one or more uniform image regions includes defining a repeating tile having a pattern of feature shapes positioned at pseudo-random feature locations. A plate formation pattern corresponding to the image pattern is determined wherein the repeating tile is applied in a tiled arrangement to the uniform image regions. The plate formation pattern is used to form a flexographic printing plate, wherein regions of the flexographic printing plate corresponding to the uniform image regions of the image pattern include a pattern of raised features in positions corresponding to the feature positions in the repeating tile.

  • Patent number: 7982758
    Abstract: An electromechanical system and a printer for maintaining a peel location of media impressed on a receiving substrate. A mounted optical probe has at least one light source and one or more photodetectors for detecting reflected portions of the light emitted or transmitted from the light source. The photodetector indicates to the system controller a distance of the media for controlling a peel location via an electrical signal. A comparator compares the electrical signal with a predetermined electrical signal reference to determine if the media is desirably positioned. The predetermined electrical reference signal corresponds to the desired peel location. The comparator compares the signal levels and outputs a correction signal used in a negative feedback loop for adjusting a velocity of a motor that drives a take-up roller for the media.

  • Patent number: 7973815
    Abstract: A method for maintaining a peel location and for peeling a layer of media from a surface in a thermal printer. An optical probe, that includes a light source and a photodetector, transmits light from the optical probe toward a first web. The web reflects a portion of the transmitted light onto the photodetector, which then outputs an electrical signal which is compared with a preselected signal level and the difference between them provides an indication as to how much adjustment the peel location requires. Adjusting the peel location may comprise changing environmental characteristics of the first web or the second web (surface) or adjusting a tension of the first or second web. The difference between the measured electrical signal levels is related to a physical distance of the first web from the desired peel location.

  • Patent number: 7742193
    Abstract: The present invention relates to an automatic print inspection method in which photographic prints are scanned to obtain digitized images. The scanned digitized image of the photographic print is compared to digital image data which represents the original captured image. The resulting digital correction data indicates whether or not there are defects in the print media or faults in the printer process, including the digitizing steps. Signal processing transformations may be used to decide how to separate media defects from processing faults and how to correct for the latter. The method of the present invention can be used as a final quality check so that any defective prints can be rejected and remade before orders go out to a customer.

  • Patent number: 6916221
    Abstract: A method of determining defects in OLED devices having a plurality of pixels, each with its own emissive layer, which are capable of being excited by input light to produce an output color light response, including illuminating one or more OLED devices or a portion of an OLED device with light in a predetermined portion of the spectrum so that the pixel emissive layers are excited to produce an output color response for each pixel, capturing an image of the output light produced by the excited pixels and converting such captured light into a digital image; and determining device pixel size, shape, location, and emitted light intensity from the digital image and comparing such size, shape, location, and emitted light intensity with predetermined acceptable size, shape, location, and emitted light intensity ranges to determine whether there is a defect in the OLED device(s).

  • Patent number: 6812997
    Abstract: A photographic printer and a method of printing in which the printer is interfaced with a defect detection or scanning system is adapted to inspect photographic paper for defects as it is consumed by the printer. In the system and method of the present invention, when a defect is detected, the printer is enabled to either skip over the defect area or to reprint the affected image. With respect to the defect, when detected, the present invention provides either for the utilization of a defect marker, such as a hole punch, which provides a physical mark on the paper in close vicinity of the defect or an electronic device capable of transmitting the precise location of the defect to the printing section. The hole or electronic signal is recognized by the printer, to enable it to either skip the defective frames or reprint the images.
