#banknotes #money #engineering #techdocumentary #manufacturing #SecurityPrinting #currency Inside the Bank of England's high-security facility, see how modern polymer British pounds are printed with microscopic anti-counterfeiting precision. This engineering documentary breaks down how polymer currency is manufactured, from raw polymer substrate film and multi-layer offset printing to metallic foil stamping, micro-laser perforation, and tactile feature embossing. This episode explores sub-micron holographic foil alignment, ultraviolet ink calibration, automated optical banknote inspection, and high-speed rotary cutting inside one of the world's most secure printing operations.
