Anti-Counterfeiting Measures (Series-D notes)

Watermark

Watermarks are created by producing variations in the thickness of the paper, and can be either light or shaded. They are combined to pattern banknotes elaborately.

Watermarks also include tactile marks to help the visually impaired people distinguish different denominations.

Intaglio printing

Image designs of the values and portraits on banknotes are thickly printed to give a notable texture.

Ultrafine-line printing

Banknote designs are drawn with extremely fine lines. Such fine lines can hardly be replicated by color copy machines, or by ordinary printing equipment or similar devices.
