Security printing

Ugra analyses security paper and banknotes and
checks the authenticity of products at suspected plagiarism.

Security paper

As an independent test laboratory Ugra is partner of paper mills in the area of security papers. We test the quality of specialty papers and their compliance with the stringent requirements of central banks. The specified properties within narrow tolerances serve the protection against counterfeiting and ensure a long life of the security documents.

  • Physical tests
  • Optical tests
  • Chemical tests
  • Production acceptance


When checking banknotes the life time of the banknotes as well as the functionality of the security features matters in particular. In our laboratory we can perform stress tests under controlled conditions and simulate and predict the life time of banknotes. Meaningful expertises help our customers to continually improve its products and adapt to changing demands.

  • Physical tests
  • Biological tests
  • Chemical tests
  • Optical tests
  • Printing production acceptance

ID cards and passports

Identity cards and passports have to meet stringent safety requirements in the age of globalized travel and increasing migration. For this Ugra checks the quality of the individual components as well as the life time of the entire product.
