Explain the pattern behind the bleed marks on Indian notes of new seriesBleed marks are the protruded oblique lines and zeros on the sides of the front of Indian notes of new currency. The bleed marks are made for blind people, because of which they can know the denomination of the note by touching or by drawing a finger over the bleed marks. I have not been able to feel any protrusion when I touch the bleed lines, though.
The notes below Rs 100 denomination do not have any bleed marks, but all the notes above Rs 50 denomination have bleed marks.
Rs 100 note has four oblique lines on each of the frontal sides.
Rs 200 note has four oblique lines and two zeroes on each of the frontal sides.
Rs 500 note has five oblique lines on each of the frontal sides.
Rs 1000 note is yet to come.
Rs 2000 note has seven oblique lines on each of the frontal sides.
There has to be some pattern for those increasing bleed marks with increasing denomination. Can someone explain the pattern of bleed marks, and with that pattern what type of bleed mark can we expect on a Rs 1000 note when it is released?
