Display apparatus with reduced susceptibility to electro-magnetic interference includes a display including an array of pixels and a ground mesh located in proximity to the display. The ground mesh includes a plurality of electrically connected ground lines located between the pixels, so that electro-magnetic radiation emitted or received by the display is reduced.

A method of making display apparatus includes providing a display having an array of pixels and locating a ground mesh in proximity to the display. The ground mesh includes a plurality of electrically connected ground lines located between the pixels, so that electro-magnetic radiation emitted or received by the display is reduced.

Making display apparatus with pixel-aligned ground mesh

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 &#x3bb;. The second radiation-sensitive layer is disposed on the first radiation-sensitive layer and is sensitive to a second imaging radiation having a second &#x3bb;that differs from the first &#x3bb;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.

Flexographic element and method of imaging

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.

Printer having differential filtering smear correction

A method for adjusting dot-gain for a halftone binary bitmap file comprises inputting a halftone binary bitmap file consisting of binary pixels () to an asymmetric digital filter (). The binary pixels are filtered with the asymmetric digital filter and generates multi-level pixels (). The multi-level pixel are compared to a preset level () and generates a binary pixel output (). The binary pixel output is collected and forms an adjusted halftone binary bitmap file ().

A first recipe () is converted using a first colorant set to a second recipe () using a second colorant set. The first recipe () is converted into a CIE_Lab estimate () using a first model and a first database (). The CIE_Lab estimate () is converted into the second recipe () using a second model and second database ().

A method for selecting a best three color solution for a CIE_Lab request comprises generating a three color database () of CIE_Lab values at specified colorant input levels. A closest point in the database with colorant input levels is found, which will produce a CIE_Lab value that is closest to the CIE_Lab request. A matrix of points centered on the closest point () is selected. A linear model to the matrix of points is found. An output color consisting of a set of colorant levels is created using the linear model.

A method for printing a halftone digital image on both a printing press and a color proofer using the same binary digital data which comprises making a printing plate from the binary digital data; making a press sheet using a press with the printing plate; sending the binary digital data to a dot-gain processor for conditioning the binary digital data to introduce a predetermined level of dot-gain; transmitting the conditioned binary digital data to the color proofer; and printing a halftone color proof on the color proofer.

Method for printing a halftone digital image

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.

Method of adjusting color in a color proof

The invention is a method for printing a color proof from an initial halftone bitmap file () having individual dots () using a spatial filter () which is created from a calibration curve () for a printing press (). The method further consists of sending an initial halftone bitmap file consisting of individual dots to the spatial filter creating a filtered output (), quantizing the filtered output from the spatial filter to 'n' levels to create a quantized image (), transmitting the quantized image to a color printer (), and printing a halftone color proof () on the color printer.
