    摘要： A system and method for the overprint on flexible supports are described. In particular, the overprint system 1 comprises a printing unit 2 comprising a rotatable printing cylinder 3, having printing zones at the surface thereof, and first actuating means 14, configured to drive in a controllable manner the printing cylinder 3 rotation. The system further comprises a first reel 5 for unwinding a flexible support 4 to be printed, which has preset zones to be overprinted, and a second reel 8 for rewinding the flexible support 4, once it has been printed. A plurality of winding rolls 7 arranges an unwinding path, for the flexible support 4, comprised between the first 5 and the second 8 reels, and passing through the printing unit 2. The system then comprises second actuation means 20, configured to drive in a controllable manner the flexible support 4 advancement along the unwinding path (upstream of the printing unit 2 in the unwinding direction), and control means 10, configured to control in a coordinated manner both the first actuating means 14 and the second actuation means 20, so as to determine at every moment a correspondence of the preset zones to be overprinted of the flexible support 4 with respective printing zones of the printing cylinder 3.

    摘要： An embossed sheet configuring a decorative sheet includes a sheet-shaped base that has translucency, and a plurality of reflective portions provided on one surface of the base. Each of the plurality of reflective portions has a reflective main surface that reflects incident light, and connecting surfaces that are provided between the reflective main surface and the base. Each reflective main surface is rectilinear on a first cross-section and curvilinear on a second cross-section. A gradient of a straight line at a center position of the reflective main surface that is rectilinear on the first cross-section, in relation to the one surface of the base, varies within a range of ±40 degrees in each of the plurality of reflective portions. As a result, the reflective portion can reflect incident light at regular and non-regular angles.

    摘要： A process for preparing a sign that includes the steps of providing a sheet of material; defining on a surface of the sheet a series of image-bearig areas and non-image-bearing areas; treating the surface of the sheet with an essentially solvent-free composition comprising a colorant and a polymeric binder to selectively deposit the composition on the non-image-bearing areas of the surface of the sheet; and fusing the composition to create a continuous polymer film on the non-image-bearing areas.
