A method for producing a screen for papermaking of a bank note, check, identification document or other security paper with a watermark by hindering paper deposit in a partial area of the screen in the form of the watermark, said method comprising the following steps:

• providing a screen for a cylinder paper machine, said screen embossed to form a relief in the screen for producing a multilevel watermark;
• and
• partially applying a sealing compound to the screen so that the screen is completely closed by the sealing compound only in partial areas in the form of the watermark later to be produced during papermaking in such a way to hinder paper deposit in the partial area by the sealing compound, said partial areas comprising the apex areas of the relief in the screen,
• wherein a mask is selected that has a surface structure adapted to the embossed relief in the manner of a negative relief, the mask being applied to the embossed relief of the screen so that its surface structure locks in.
