Lithographers sought to find a way to print on flat surfaces with the use of chemicals instead of relief or intaglio printing.
The notes are printed using the intaglio printing process.
Shortly before 1990, two groups working independently developed different ways of applying it to creating intaglio printing plates.
However high-pressure web intaglio printing, front and back of the intaglio process, was a totally new idea.
The new design employs offset printing in favor of the intaglio printing used in the 2005 series.
Traditionally, anti-counterfeiting measures involved including fine detail with raised intaglio printing on bills which allows non-experts to easily spot forgeries.
There is intaglio printing through the bill which gives it an embossed feel.
This allows a flat print plate to be used, enabling much longer and more detailed print runs than the older physical methods of printing (e.g., intaglio printing, letterpress printing).
