The Royal Bank of Scotland (RBS) has issued its new Â£5 which has been produced by De La Rue on its Safeguard polymer substrate.Following a widespread public consultation exercise run by the bank, the note theme of 'natural colour and light' was chosen to underpin the design elements of the new note. The Scottish novelist and poet Nan Shepherd features on the front of the note with the Cairngorm mountains in the background. Mackerel fish appear on the back in recognition of their importance as the single most valuable species for the Scottish fishing industry.De La Rue says it worked in collaboration with the RBS design teams and maximum use is made of the clear window that is the hallmark of Safeguard banknotes. The RBS logo is printed using SPARK Orbital optically variable ink in the window, allowing it to be seen from both sides of the note."This is an exciting time and we are delighted with our new 'people's' banknotes," said Malcolm Buchanan, chairman of RBS Scotland. "The public input into the design themes was vital and we are grateful to De La Rue for helping us to bring the ideas to reality."
