PANGKALPINANG, NETRALNEWS.COM - Bayu Martanto, Head of Representative Office of Bank Indonesia (BI) for Bangka Belitung province, said the printing of rupiah banknote uses a security technique called rectoverso to prevent the banknote from being easily imitated or faked.

“Rectoverso is a special printing technique on a banknote which makes an image fill in for another image. An image at the same position is printed on the front and is printed on the back,” Bayu said. as quoted by Antara.

The image looks irregular if viewed from one side only, and the original image is only visible when the banknote is displayed in overlay. “In the rupiah banknote, the image will form the logo BI, short for Bank Indonesia. With the rectoverso technique, part of the image on the banknote will look irregular when viewed from one side, but will show a clear and intact picture when highlighted or displayed on overlay,” he said.

He added that it was not true that the 2016 emission banknote’s rectoverso logo looked similar to a certain symbol. “All the elements in the rupiah banknote is made in such a way in the interest of securing the banknote from being easily counterfeited,” Bayu said.

Bayu continued that Rectoverso technique had been applied in printing rupiah banknotes since 1993, while Bank Indonesia’s logo has been used in the technique since 2001.

 The printing of rupiah banknotes is strictly controlled by BI. Rupiah banknote printing is only conducted by state-owned printing company Perusahaan Umum Percetakan Uang Republik Indonesia, also known as Peruri.

“The banknote printing conducted by Peruri is under strict control of BI and the Supreme Audit Agency (BPK),” Bayu said. If there is a failed print, Peruri is obliged to return the money to the central bank to be destroyed.

In addition, BI has officially published eleven rupiah banknote denominations for 2016 edition, consisting of banknote bills for 100,000, 50,000, 20,000, 10,000, 5,000, 2,000, and 1,000 denomination, as well as coins in the denomination of 1,000, 500, 200, and 100.

“Rupiah banknotes from the printing year of 2014 are still valid for use until set to be revoked,” Bayu added. (*)
