For technical reasons, the OMR sheets are printed in different combinations of Red, Orange, and Yellow colors. How to scan color OMR sheet is not a difficult job. Commonly you will find such sheets in pink color with a combination of black. The reason to use pink color is because it’s quite crowning, which makes it quite simple to handle on the screen by the scanner or the software. It is possible to remove all the matter present in pink color which make it easy to check the accurate answers or the darken ovals. This process of removing the colored matter from the sheet is referred to color dropping.
Only advanced versions of scanners are equipped with such feature. It is possible and in fact simple to scan OMR sheets in colorful format. Modern scanning software's, such as the Addmen OMR scanning software come with the color dropping feature.
With a more advanced scanner, it is possible to drop all the color from an OMR sheet and can have scanning only in Black & white format.
It is not always necessary to have high end scanners for this task. If they are not available and the scanning is not as good as it needs to be, it is still possible to have accepted scanning in Black & white format.
You can use mid-range scanners that are reasonably priced to help you scan the OMR sheets accurately. Scanned images will be read accurately by the Addmen OMR software. Feel free to contact us if you want any more clarifications in how to scan colored OMR sheets.
