摘要:
Embedding data in printed image features on a receiver printed with an offset printing process includes a first offset printing member (240) for forming an image (320) on the first offset printing member. A second offset printing member (260) is roughened in one region (280) of the second offset printing member within a boundary of an image feature on the first offset printing member to embed data (330). Ink is applied to the first offset printing member and transferred from the first offset printing member to the second offset printing member. The ink from the second offset printing member is applied to a receiver (305) and the embedded data is printed within the boundary of the at least one image feature transferred to the receiver.

A relief (or flexographic) printing precursor has first and second radiation-sensitive layers, or a plurality of radiation-sensitive layers. The first radiation-sensitive layer is sensitive to a first imaging radiation having a first λmax. The second radiation-sensitive layer is disposed on the first radiation-sensitive layer and is sensitive to a second imaging radiation having a second λmax that differs from the first λmax by at least 25 nm. An infrared radiation ablatable layer can be present and is opaque or insensitive to the first and second imaging radiations and contains an infrared radiation absorbing compound. These relief printing precursors can be used to prepare flexographic printing plates, cylinders, or sleeves where the ablatable layer is used to form an integral mask on the element. Use of the invention provides a relief image without any loss in the strength of the small dots and can be carried out using multiple irradiation steps using the same apparatus.

A method of making a composite device, includes providing a first part including a first set of components at a first pitch; along with providing a second part including a second set of components at a second pitch, different from the first pitch. The first part is fastened to the second part to make a composite device. The composite device includes a subset of the first set of components that are substantially aligned to a subset of the second set of components to form a corresponding subset of substantially aligned composite components.
摘要:
A number of lasers (402) used to image a bitmap file (630) of a halftone screen is comprised of generating a first bitmap file (630) for a first color. A first image (710) is printed with the first bitmap file for the first color with n lasers. A second image (720) is printed with the first bitmap file for the first color with n−1 lasers. An optimum number of lasers is selected for printing the first bitmap file based on the image with the least number of defects (700).
摘要:
A method for adjusting dot-gain for a halftone binary bitmap file by inputting a halftone binary bitmap file comprising binary pixels to a digital filter, filtering the binary pixels with the digital filter generating a weighted sum of the binary pixels producing a first set of multilevel pixels, filtering the binary pixels with a second digital filter producing a second set of multilevel pixels, sampling the second set of multilevel pixels at a preset sample rate identifying a set of sampled multilevel pixels, inputting the set of sampled multilevel pixels to a lookup table to create an output that is a threshold level for the set of sampled multilevel pixels, using the first multilevel pixels and comparing to the threshold level for the set of sampled multilevel pixels and generating a binary pixel output, and collecting the binary output and forming an adjusted halftone binary bitmap.

A method for adjusting dot-gain for a halftone binary bitmap file, a method for adjusting the dot-gain for a halftone binary print, and a method for adjusting the dot-gain for a printing plate, wherein each method involves inputting a halftone binary bitmap file consisting of binary pixels to a digital filter, then filtering the binary pixels with the digital filter and generating a weighted sum of the pixels, using the weighted sum, producing a multilevel pixel and then comparing the multilevel pixel to a preset level, next a binary pixel output is generated, the output are collected and an adjusted halftone binary bitmap file is formed.
摘要:
A printer capable of forming an image on a receiver substrate according to type of receiver substrate, and a method of assembling the printer. An identifier containing identifier information is associated with each component of the receiver substrate which, for example, comprises paper and, optionally, laminate media. A sensor is disposed to read the identifier information so that an image forming operation can be adjusted based on identified receiver substrate components and media. For example transponder, serving as the identifier, is coupled to a memory device capable of storing information characteristic of media type. A transceiver, serving as the sensor, is disposed within the printer. The transceiver includes antennae disposed for polling an individual transponder attached to each media type. The transponder receives a first radio frequency field from the transceiver and, deriving power and address information from the first frequency, then generates a second radio frequency field in response. The second radio frequency field is characteristic of the data stored in the memory. As instructed by a control logic processor, the transceiver can both read manufacturing data from the transponder concerning the media type or write usage and processing data to the transponder for storage in the memory.

A print having information associated with the print stored in a memory coupled to the print. A print, processed by an image processing apparatus, having an attached memory for storing detailed information about the print and allowing contactless access using an electromagnetic frequency signal. A transceiver, connected to a control logic device, communicates with a transponder that is attached to the print substrate and is integrally coupled to the memory. The transponder is capable of receiving a first electromagnetic field (frequency) from the transceiver and deriving power and address information from the first frequency, then generates a second electromagnetic field (frequency) in response, where the second electromagnetic field is characteristic of the data stored in memory.
