Obsidian Plus – Glass Bead Blanket

The Obsidian Plus glass bead blanket, designed for applications such as sheetfed gravure, hot-foil and cold-foil embossing, security and RGB printing. The Obsidian Plus blanket has a cover layer made of tiny glass beads and is ideal for bank notes, certificates or packaging films for high-quality products: Instead of using printing ink in the hot embossing process, a thin plastic film is applied to the printing stock by means of pressure and heat.

The blanket plays a vital role in this and must be able to repel the ink so that no smearing on the sheet or other elements occurs. On the other hand, the printing blanket must withstand enormous press, therefore, requires very high mechanical stability.
