Step 01: The firststepis designingthe OMRsheet.One can designanOMR sheetusingthe OMR sheet
readersoftware. One cancustomize the OMR sheetoruse one of the formatsalreadyavailable onthe
software.
Step 02: Once the sheetisdesigned,the nextstepis toprintthem.Asin earliertimes,itisnotnecessary
to use thicksheetstoprintthe OMR sheets.Onthe otherhand,any type of A4 size printingsheet,be it
thickor thin,can be usedforprintingthe OMR sheets.However,itis importantthatonlywhite paperis
usedforthe purpose.Anylaseroroffsetprintercanbe usedforprintingthe OMR sheets.Evengood
photocopiesof OMRsheetscan be used.
Step 03: Afterthe OMR sheetsare filled,theyare scannedusingaflatbedorADF scanner.AnOMR
scanneris notrequiredforthe purpose because the OMRsoftware readsscannedsheets.Inother
words,the OMR scannerdoesnotdo the reading.The scanningdoesnotneedtobe perfecttoo.The
software canread skewed,titled, distortedandrotatedsheetswith100% accuracy.
Withthe introductionof OMRsoftware,designing,printingandscanningOMRsheetshave become
easier.Moreover,ithasalsoreducedthe costof printingOMR sheets.
