Abstract:
A method for providing user interaction with a printed page (10) includes providing artwork (20) for a first page to be printed; providing a printing model to simulate a first printed page using the artwork; simulating the first page to be printed using the printing model; extracting a first set of features from the first simulated page (220); and embedding the first set of extracted features in a first URL (270). The invention includes printing the first page; capturing a digital image of the printed page (415) with a mobile device (400); extracting features (430) from the digital image; generating the URL associated with the digital image using the features extracted from the digital image; and navigating to the generated URL using a web browser (470).
Abstract:
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.
Abstract:
A first recipe (10) is converted using a first colorant set to a second recipe (50) using a second colorant set. The first recipe (10) is converted into a CIE_Lab estimate (30) using a first model and a first database (20). The CIE_Lab estimate (30) is converted into the second recipe (50) using a second model and second database (40).
Abstract:
A method for adjusting dot-gain for a halftone binary bitmap file comprises inputting a halftone binary bitmap file consisting of binary pixels (400) to an asymmetric digital filter (500). The binary pixels are filtered with the asymmetric digital filter and generates multi-level pixels (506). The multi-level pixel are compared to a preset level (408) and generates a binary pixel output (410). The binary pixel output is collected and forms an adjusted halftone binary bitmap file (270).
Abstract:
A method for converting an original halftone bitmap image to a color converted halftone bitmap image. A set of asymmetrical morphological filters is provided. The original halftone bitmap image is segmented into blocks and for each block: apply the set of morphological filters to the original halftone bitmap image to produce a set of modified halftone bitmap images; estimate the percent dot area of the original halftone bitmap image and the set of modified halftone bitmap images; a predetermined dot-gain to the percent dot area of the original halftone bitmap image to produce a modified percent dot area; select the modified halftone bitmap image whose percent dot area is closest to the modified percent dot area to produce a block of the color corrected halftone bitmap image; and replace the original halftone bitmap image with the combined blocks of selected modified halftone bitmap image.
Abstract:
In a method and printing apparatus, a receiver is moved in a travel direction relative to a print engine. The print engine has a predetermined profile of smear in the travel direction at a plurality of sites on the receiver. Each site corresponds to a respective one of the pixels. A digital image to be printed with the print engine is received and digitally filtered based on the profile to provide a filtered image. The filtering is localized, non-symmetrical, and at least partially compensatory of the smear. As the receiver is moved, the filtered image is printed on the receiver, the printing being modulated in accordance with the filtered image.
Abstract:
The invention is a method for printing an image (10) from a halftone binary bitmap (12) having pixels (14a-14g) comprising the steps of: creating a feature location identification filter (16) for a halftone binary bitmap image; using the feature location identification filter to map pixel identifications (18a-18g); assigning a location specific exposure (20a-20g) to the mapped pixel identifications; and exposing media using the location specific exposures to create an image (10) on a printer (24).
Abstract:
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.
Abstract:
Imaging apparatus capable of forming an image consistent with type of imaging consumable loaded therein, and method of assembling the apparatus. The imaging apparatus reports the consumable type and manufacturer batch identification to a remote computer. The remote computer responds by returning batch-specific information that may affect processing parameters for the imaging apparatus. In the preferred embodiment, an electrically programmable read/write memory contained in a transponder is integrally attached to the consumable package. The transponder communicates with a transceiver, disposed within the imaging apparatus. The transceiver has antenna and support components for polling each transponder. As instructed by a control logic processor, the transceiver can both read manufacturing data from the transponder about the consumable and write usage and processing data to the transponder for storage in memory. A networked server connects to the control logic processor and to a network for communication with remote computer.

A transceiver unit is disposed proximate the shaft. The transceiver is capable of transmitting a first electromagnetic field and sensing a second electromagnetic field. A transponder including a semi-conductor chip is integrally connected to the shaft and has encoded data stored in the chip indicative of the type of media ribbon. The chip is capable of receiving the first electromagnetic field to power the chip and then generating the second electromagnetic field as the chip is powered. The second electromagnetic field is characteristic of the data stored in the chip. The transceiver unit senses the second electromagnetic field, which second electromagnetic field has the data subsumed therein.
