Multitone Watermark

Multitone watermarks for banknote portraits and motifs

Multitone cylinder mould watermark security features are proven over the centuries for displaying banknote portraits and motifs. Examining the watermark to check the authenticity of a banknote poses a formidable barrier against counterfeiting. Given the high level of recognition of watermarks around the world, even tiny aberrations in the portrait or the motif are spotted immediately. Although tried for centuries, attempts of counterfeiting a watermark only result in imitations such as poor quality prints.

Fibers are deposited in different densities during the papermaking sheet building process to vary the thickness of the paper producing an effect of finely modulated transition. This creates clearly defined three-dimensional images, such as portraits, that when held against the light, become visible. The contrast between bright and dark areas and their light graduations create a multitone watermark effect that can only be achieved through cylinder mould technology.
