Abstract: Methods and apparatus to control roll-forming processes are disclosed. A disclosed example roll-forming apparatus includes an inlet portion to receive material, an outlet portion from which the material exits the roll-forming apparatus, a plurality of rollers extending between the inlet and outlet portions, a sensor to measure at least one dimension of the material as the material moves through the roll-forming apparatus, the material measured by the sensor between the inlet and outlet portions, and material adjuster circuitry to adjust roll-forming of the material by moving at least one of the plurality of rollers based on the at least one dimension.

Abstract: One example provides a method. The method includes printing an image on a surface of laminate, the laminate including: a backing layer; and a transparency disposed over the backing layer. The transparency may have a first side having the image printed thereon and a second side disposed over a first side of the backing layer, the second side opposite the first side. The method may include detaching the second side of the transparency from the first side of the backing layer and reattaching the first side of the transparency to the first side of the backing layer to form a laminated image. The method may include disposing the laminated image over a substrate surface having a curvature.

Abstract: An image forming method comprises stretching a pixel row to a height greater than that of the pixel row to generate a barcode image. The barcode image is formed on a face of a media page at an edge such that the imaging material forming the barcode image forms the pixel row on the edge of the media sheet.

Abstract: The present disclosure provides composite support material and associated methods used in the fabrication of three-dimensional objects. In one example, a composite support material for three-dimensional printing can include a soluble filament core that is soluble in a solvent and is encapsulated with an insoluble shell that is insoluble in the solvent. The composite support material is stable in air and, when printed, is dissolvable in the solvent.

Abstract: An inkjet recording medium includes a substrate, a base layer disposed on the substrate, and an ink receiving layer disposed on the base layer. The ink receiving layer includes cationically-modified fumed silica having nanoparticles of alumina and/or silica mixed therein. The alumina nanoparticles have an individual particle size ranging from about 15 nm to about 50 nm, and the silica nanoparticles have an individual particle size ranging from about 5 nm to about 45 nm.

Abstract: A method of producing and using photo media to print a glossy, photo-quality image. The image is printed onto the back of a coated transparent base. Thereafter, an opaque backing is applied to cover the printed image. The resulting print is viewed from the front, which provides the photo-quality, attractive appearance primarily because of the substantial gloss depth and uniformity attributable to the transparent base. The transparent base and backing protect the ink-receiving coating and make the resulting print very durable. The image is light fast because the ink is sandwiched between the transparent base and the backing, thereby sealing the ink from oxygen. In a preferred embodiment of the present invention, the backing is applied as a liquid using substantially the same mechanism as used for printing the image.

Abstract: A method and system of capturing an image comprises extracting image characterization information from an image file, extracting digital image data from the image file, printing a visually perceptible image described by the digital image data on one side of a medium, printing a visually perceptible representation of the image characterization information on an opposite side of the medium, and retrieving the image characterization information from the visually perceptible representation of the image characterization information on the opposite side of the medium.

Abstract: An eyeglass appliance is provided with an eyeglass lens and an eyeglass frame. The eyeglass frame includes a lens retaining structure configured to engage with an edge portion of the lens to retain the lens. The lens retaining structure has magnetic properties completely through a cross-section of the lens retaining structure sufficient to magnetically affix the eyeglass appliance to magnetizable material of a complementary eyeglass appliance.

Abstract: An eyeglass accessory frame includes an auxiliary frame. The auxiliary frame includes a heat-treated magnetic alloy. The heat-treated magnetic alloy of the auxiliary frame is configured to magnetically couple the auxiliary frame to a primary frame having magnetizable material. A method is also provided.
