Abstract:
An article having a patterned metallic film on a surface thereof, and methods of producing such an article, the article including: (a) a porous substrate having a first porous surface; (b) a patterned metallic film attached to the first porous surface, including (i) a first patterned polymeric layer attached to the first porous surface; and (ii) a patterned metallic layer attached to the first patterned polymeric layer, on a distal side with respect to the first porous surface; wherein a thickness of the metal layer is at most 3 μm.
Abstract:
A method for patterning a metal layer on a substrate is disclosed. Furthermore, a kit comprising a first composition comprising a reducing agent and a second composition comprising a metal salt, and an article comprising a substrate in contact with a metal layer are also disclosed.
Abstract:
A Raster Image Processing (RIP) module includes an object detection module configured to receive at least one input file, detect objects in the at least one input file and create at least one image comprising a predefined number of stripes along the edges of the detected objects, an edge processing module configured to receive the at least one image and process the at least one image by changing the gray level of each one of the objects' stripes according to an edge processing table; and a dithering module configured to receive the at least one processed image, dither the at least one processed image according to the at least one image's gray levels and output a printing ready file.
Abstract:
A method of adaptive 3D metallic overprinting of a first digital image over a pre-printed second image including at least one feature, the method captures an image of a substrate pre-printed with the second image and with at least one registration mark. The substrate includes at least two layers, a paper layer and a metallic layer. The method automatically computes one or more offsets from intended predetermined properties of the at least one registration mark and one or more compensation adjustment values to be applied to properties of the at least one feature, based on the one or more computed offsets. The computed one or more compensation adjustment values is applied to the first digital image to create a corrected digital image. The corrected digital image is printed over the second image.
Abstract:
Disclosed are systems and methods, including a method that includes depositing a curable adhesive onto a first surface of a substrate in a pre-determined pattern, placing topping material onto the substrate with the deposited adhesive, and applying UV energy to the substrate including the deposited adhesive and the placed topping material to cause curing of the deposited adhesive.
Abstract:
Disclosed are systems, machines and products for producing foil relief The system includes apparatuses for placing a foil on a curable adhesive deposited on a substrate when the curable adhesive is substantially non-tacky, and applying energy to the adhesive deposited on the substrate while pressing the foil to the adhesive to cause the adhesive to become tacky and to adhere to the foil. The adhesive becomes substantially fully cured prior to completion of the pressing of the foil to the adhesive deposited on the substrate. In some embodiments, the system may further include one or more energy sources for pre-curing the curable adhesive prior to placing the foil on the adhesive to initiate the curing process of the adhesive and manipulate a viscosity level of the adhesive, with the pre-cured adhesive remaining substantially non-tacky. The curable adhesive includes one or more of, for example, a radical type adhesive and/or a cationic adhesive.
