The bubbles are one of the most significant components of the OMR sheets. The bubbles found on the OMR sheets must be filled completely. This is on the grounds that the OMR programming reads dark marks on the OMR sheets. This makes it imperative to have the right bubble size while creating OMR sheets.
The OMR sheet designing software gives the option to change the size of the bubbles to fit the same number of quantities of bubbles in a single sheet of paper. Nonetheless, there is an ideal size for the bubbles as well. This must be considered while planning the sheet. It is beyond the realm of imagination to expect to make the extent of the bubbles too little to even think about fitting every one of the bubbles in a single page.
The ideal size of the bubble is between 50-60 pixels. This gives adequate difference with the thickness of the outlines just as that of the printed matter inside the bubbles. The bubble size ought not be excessively small as this would pressure on the student’s fingers while filling them without making the ink spread to the adjacent bubbles. Too little bubbles would need to be read at higher affectability, which could prompt a ton of dismissals and cautions, along these lines expanding the session of the evaluation process. The size of the bubbles ought to likewise not be excessively big. It would take the student’s a ton of time to fill every one of the bubbles totally and legitimately. Because of this, they would lose a great deal of marks as they would not have the capacity to finish the paper.
Aside from the size of the bubbles, the separation between the bubbles ought to likewise be dealt with. There should be adequate and equivalent separation between the bubbles. Abstain from packing the bubbles as this could prompt flawed evaluation.
The extent of the content inside the bubbles is additionally a significant factor. The content names should not be striking or thick as the OMR software may get befuddled and may see it as a dark mark. Subsequently, keep the content substance slight and little. This must be kept up on the off chance that the OMR sheet is high black and white. The content inside coloured OMR sheets are dropped during scanning alongside the colour and henceforth the size of the text labels doesn’t matter in the case of coloured OMR Sheets.
Ensure that you pursue the guidelines with respect to the measure of the bubbles while structuring the OMR sheets. This would ensure that the students can fill the bubbles appropriately with no issues and the OMR programming can read the markings with no disarray.
