摘要： There is disclosed a laminate comprising alternating polymer sheets and metal layers between the polymer sheets, the laminate being substantially free of adhesive. Each polymer sheet of the laminate has a thickness not exceeding about 25 .mu.m, and the resistivity of the metal layer is from 1 to about 4 ohms/square. Such laminates are useful in making capacitors and piezoelectric multimorphs.A method of making such laminates is also disclosed, wherein a plurality of metal-coated polymer sheets are compressed, in the absence of an adhesive, under pressure sufficient to reduce the thickness of each of the polymeric film layers to a value that is no larger than about 25 .mu.m.

摘要： Patterned light-blocking elements are prepared using a method having operations A′) through F′), or a method having operations A″) through G″). Such methods include providing an ii) embossed and densified foamed opacifying layer on the back side of a i) fabric and a iii) non-foamed function composition on the ii) embossed and densified foamed opacifying layer. Embossing can be carried out using any suitable embossing means including a continuous embossing belt or web or an embossing roller or sleeve. The embossing operation provides a visible relief pattern in the ii) embossed and densified foamed opacifying layer that can be viewed from the face side of the patterned light-blocking element when appropriately backlit as a transmissive display in a darkened environment. Such elements can be used as window treatments as well as decorative fabrics in various environments.

摘要： A method of printing on an inkjet printer including a plurality of overlapping jetting modules includes analyzing image data within a stitch area to designate white pixels and non-white pixels. For rows where the stitch area includes white pixels, a hard stitch boundary is defined within the stitch area where image pixels to the left of the hard stitch boundary are to be printed using a left jetting module and image pixels to the right of the hard stitch boundary are to be printed using a right jetting module. For image regions where the rows of image pixels within the stitch area include only non-white pixels, a soft-stitching path is defined through the image region, and a fading function is used to gradually transition from printing image pixels with the left jetting module to printing image pixels with the right jetting module in a transition zone around the soft-stitching path.

摘要： An aqueous colored pigment-based ink that is capable of fluorescence, has a pigment colorant in an amount of 1-7 weight %; a non-polymeric fluorophore that when excited by fluorescence-exciting radiation having a peak of at least 200 nm and up to and including 400 nm, exhibits an emission peak of at least 400 nm and up to and including 750 nm, and which non-polymeric fluorophore is present in an amount of 0.1-2 weight %; and an aqueous medium comprising water. This aqueous colored pigment-based ink can be included in an ink set that also includes one or more aqueous colored pigment-based inks that are non-fluorescent. All of these inks can be applied using continuous inkjet (CIJ) printing, onto non-UV fluorescent substrates to provide images that can be detected when excited as noted above, which images can be provided on articles such as security documents, currency, and lottery tickets.

摘要： A method for reducing image burn-in artifacts in an electrophotographic printing system, includes receiving a print job including image data for a set of pages to be printed. The pages are analyzed to determine that the image data for a sequence of pages in the print job are similar. The similar pages are printed using a pattern of lateral translations wherein the image data is laterally translated such that it is printed at a different lateral position on the printed page. The similar pages can also be printed using a pattern of page orientations including a first page orientation and a second page orientation, wherein the image data for the second page orientation is rotated 180 degrees relative to the image data for the first page orientation.

摘要： An electrophotographic printing system for printing with a set of toners including a white toner. A plurality of printing modules are configured to print respective toner patterns, each including a toner image printed onto a receiver medium being transported on a transparent transport web and a corresponding registration mark positioned outside a border of the receiver medium. A first registration mark sensing system is positioned to detect the registration marks printed with a first subset of the toners that doesn't include the white toner. A second registration mark sensing system is positioned to detect the registration marks printed with a second subset of the toners that includes the white toner. The registration mark sensing systems each include a reflector plate positioned behind the transport web. The reflector plate for the first registration mark sensing system is white, and the reflector plate for the second registration mark sensing system is black.

摘要： An aqueous composition can be used for pre-treating a substrate prior to inkjet printing to provide a white opaque background for inkjet-printed images. This aqueous composition includes: (a) one or more water-soluble salts of a multivalent metal cation at 5-30 weight %; (b) a nonionic or cationic water-soluble or water-dispersible polymeric binder material at 5-30 weight %; and (c) surface-treated visible light-scattering particles having a D50 (median) particle size of at least 0.04 μm and up to and including 2 μm in an amount of 5-60 weight % based on the total aqueous composition weight. The pre-treated substrate is useful as an inkjet receiving medium that can be readily inkjet-printed particularly with anionically-stabilized aqueous pigment-based inks.

摘要： A media transport system is used to transport a media sheet along a media transport path past an image capture system. The image capture system includes an image capture device positioned to capture an image of the media sheet, and a platen positioned behind the media sheet, wherein a surface of the platen includes a non-uniform density pattern. The image capture system captures an image of the media sheet that includes at least one edge of the media sheet and a portion of the platen that extends beyond the edge of the media sheet. An image analysis system automatically analyzes the captured digital image to detect an edge position of the media sheet by detecting a platen region that includes the non-uniform density pattern and a media region. The detected edge position is used to adjust a position that a printing module prints image data onto the media sheet.
