The front and back of all banknotes have figures formed by lines of colors which give the main color to the banknote. These figures are difficult to imitate with printers or photocopy machines as they have dotted-base figures instead of line-based figures. A magnifying glass is recommended to better observe these figures. Here are some examples:
