Patent number: 8524039Abstract: A screen for producing two-level watermarks is produced by completely closing part of the screen with a viscous sealing compound, which is subsequently cured actively or passively. At the thus closed partial areas of the screen, paper deposit is hindered during papermaking so that the finished paper appears light in transmission in the areas. A mask is used for exactly positioning the sealing compound in the partial areas of the screen and/or for curing the sealing compound only in the given partial areas, whereby in the latter case the uncured areas of the sealing compound are washed out.Type: GrantFiled: September 13, 2002Date of Patent: September 3, 2013Assignee: Giesecke & Devrient GmbHInventors: Wittich Kaule, Karlheinz Mayer, Bernd Stumbeck, Wolfgang Wensauer, Guenther Wild, Thomas Gerhardt, Andreas Aigner
