With an array of substrate feature and component options available,
the watermark is and remains the undisputed king.
Recommended by Interpol for use in high security documents, cylinder mould made paper is recognised as being the most secure paper type available, and, despite developments in scanning, photocopying and digital photography techniques, our three-dimensional multi-tonal cylinder mould made watermark remains virtually impossible to simulate.
With over 300 years of experience and expertise in making high security papers
and watermarks, at Portals we are proud to be one of the only paper manufacturers
in the world dedicated to producing high-security, non-currency paper,
on cylinder mould machines.
