Le 30 juin 2016, 06:04 dans Humeurs 0

OMR sheets possess several important components which distinguish it from a normal piece of paper with bubbles. This special sheet has black colored index points on its four corners, which are reference points that mark the beginning and end of the OMR sheet. These index points are not randomly placed at these areas. Rather these marks are placed at measured distances which help the OMR reader to record the marked bubbles accurately. However, it is important to know how to handle OMR sheets, as even a small mistake or damage can hamper the accuracy of the reader.

The first rule about handling OMR SBR rubber sheet  is that you should never fold the sheet. Be it an answer sheet, an admission form or any other form of OMR sheet; make sure that you do not fold it for ease of carrying or any other purpose.

Another thing that you should avoid is stapling, tying or punching the sheet for storing. Staple pins can damage the scanner lens. On the other hand, the punch marks on the sheet can be considered to be a marked bubble by the scanner, causing you to receive incorrect results. Tying the sheets with threads can also hamper with the results. The best way of storing the OMR sheets is to place each one of them in individual envelops. This will prevent you from using threads, stapler or punching machines or even folding or rolling the sheets.

Writing something or doing your rough work near the index points or anywhere else on the OMR sheet can lead to inaccurate reading. This is an important thing that students must remember about handling the  NBR rubber sheet . The students should also be careful about the type of instrument they use to fill the OMR sheet. They should follow the instructions provided on the answer sheet for this purpose. Most exam boards prefer the use of black/blue ball pen or pencil. Never use a gel pen or ink pen as they are likely to blot and spill on the other side of the sheet. Too much of ink can spoil the appearance of the paper, making scanning and reading very difficult.

A thing that the exam staff has to take care of, apart from storing the sheets, is to ensure that they stamp at the right place and sign at the allotted space only. If they stamp or sign anywhere near the index points, they are hampering with the scanning and recording process. So, they have to be careful about this. Hopefully, you have got the answer to the question how to handle OMR sheets. Follow these instructions to ensure that the papers or sheets are not damaged in any way.
