A. The conventional paper is used.
B. Braille paper is about as thick as a file folder or index card.
C. Any kind of paper can be used.
D. A 75 GSM thick paper is used.

Answer 1

Hint: Interpoint is the offset braille printing so that the paper used can be embossed on both sides. The dots on one side appear between the divots that form the dots on the other side. If an error is made, braille letters cannot be erased and written over effectively.

Complete answer: Braille is a universally accepted system of reading and writing by touch for blind people. The script consists of different arrangements of dots which make up the letters of the alphabet, numbers and punctuation marks. The braille paper is about as thick as a file folder or index card. Braille involves the use of six dots, and the direction of writing is from left to right. The characters have rectangular blocks called cells that have tiny bumps called raised dots. The paper used is thick as a file folder or index card for proper sensing by the visually impaired people. Most of the braille embossers support around 34 to 40 cells per line, and 25 lines per page.
Hence, the correct answer is option B.

Additional Information: Different Braille typewriters use different papers. A large interlining Stainsby consists of 36 cells per line and 18 lines per page. A Perkins braille typewriter supports a maximum of 42 cells per line, and typical paper allows 25 lines per page. It is manually operated, and its margins are adjustable. An A4-sized Marburg braille frame allows Interpoint braille (dots on both sides of the page, offset, so they do not interfere with each other). It has 30 cells per line and 27 lines per page.

Note: Louis Braille invented the Braille system in 1824. He was blinded at an early age of three. He was a student at the Institution Nationale des Jeunes Aveugles (National Institute for Blind Children), Paris. The Frenchman Valentin Haüy was the first person to emboss paper as a means of reading for blind people.
