Design of Colored OMR Sheets

OMR sheets can be printed in black and white as well as color. The color of the OMR sheets depends on the OMR marking pattern. The OMR software detects and reads dark, black marks and hence candidates are asked to fill the OMR bubbles completely.

Need for Colored OMR Sheets

In such case, the black and white OMR sheets work perfectly as the software can distinguish between the dark marks on the bubbles and the thin lines of the outlines and other stray marks. However, if tick mark is the marking pattern, then the software would not be able to distinguish between the thin mark and other stray marks on the black and white OMR sheet. Hence, colored OMR sheets are used.
