All About OMR Sheets

OMR Sheets are special printouts containing circles or elliptical bubbles or boxes used as marking areas where the candidate marks using a blue/black pen or pencil.

OMR Sheet is also known as: OMR Answer Sheet, OMR Test Sheet, MCQ Test Sheet, ORS, Objective Response Sheet, Oval Sheet, Bubble Sheet etc.

The OMR Sheet Reader software is a software solution that reads these specific circles and bubbles and converts the information into OMR data.

False Concept about OMR Sheets > People mostly think that OMR sheets are essentially based on 2-coloured, thick paper that must be purchased from specialized vendors. This is not true.

Current knowledge about OMR Sheets > The fact is that today more than 90% OMR users design & print their own OMR sheets using our OMR sheet design software.

OMR Sheet / OMR Answer Sheet

New type OMR Sheet for simple design & printingOMR Answer sheets are used for conducting Multiple Choice Question (MCQ) based Tests.

OMR Answer Sheets are basically used by educational institution for conducting regular Objective test in class or for Admission or Scholarship.

Addmen OMR Answer Sheet Checker (Module A) is required for reading such test answer sheets. This OMR test answer sheet checker has inbuilt OMR answer sheet design software.





OMR Form / OMR Application Form

OMR Form with OCR Image & BarcodeOMR data capture forms are used for gathering the details of all the candidates.

OMR forms are an easy way of OMR data collection and analysis.

OMR Forms are mostly used by Educational Institutions, Recruitment Firms, Feedback & Survey Companies, and Marketing Research Firms, to save time and get accurate information.

Addmen OMR Form Reader Software (Module B) is required for reading such sheets, and it comes with an inbuilt OMR form designer.




OMR Form + OMR Answer Sheet (Hybrid)

Old Pattern sheets can also be used- Not RecommendedOMR Sheets which have some fields for data collection and others like questions and roll no. related to test are called hybrid sheets.

A hybrid sheet is a combo of OMR test sheet and OMR application form.

Hybrid sheets are mostly used for collecting data at the time of Admission or Scholarship tests, where the participant is anonymous to the educational body.

Also used in government exams to cross validate information already provided in application form.

Combo of OMR Answer Sheet Checker + OMR Form Reader (Module A+B) is required.

OMR Sheet Design

Many different types of blocks can be placed on a OMR Sheet like:

  • General MCQ Block (for answers in ABCDE format);
  • Numeric Block (for number value or Integer answer in 0,1,2,3..format);
  • Matrix Block (for column matching type response or true and false type answers);
  • Alpha-Numeric Block (for collecting candidate name and other details)
  • Image Block (for capturing candidate picture & signature)
  • OCR Block (for capturing Form/Sheet No. from pre printed text)
  • Barcode Block (for capturing Form/Sheet No.)

OMR Sheets are created using OMR Sheet Design Software. This OMR form designer is integrated in the Addmen OMR Software.

All OMR Sheets have black index points at four corners of the sheet – the most important parameter of an OMR Sheet. Any design just containing bubbles cannot be called an OMR Sheet because it might not have correct parameters and dimensions as per OMR requirements. So it is important that the OMR sheets to be read the OMR sheet checker software are created using the OMR sheet design software.

Instructions for OMR Sheet Printing

OMR sheet format used in Addmen OMR Software are very simple to design and economical to print. Now the OMR sheet cost is almost negligible as you can print your own OMR sheets.

Paper used for OMR Sheet Printing

Laser or Inkjet OMR Sheet Printer >

  • OMR Sheet printing can be printed using a Laser Printer or rezograph or digital copier printer.
  • Set the printer page to A4. Mostly standard page is set as ‘Letter’. Change it to A4.
  • Check that the inkjet printer is able to print without smudging or blotting.

OMR Sheet Printing on Offset >

  • OMR sheet printing can also be made through Offset Printing.
  • Only print using Plates. DO NOT print using tracing sheet or master.
  • Use the CorelDraw file to make plates.
  • While cutting the sheet after printing, all pieces should be of equal size.

OMR Sheet Printing using Photocopy >

  • Photocopier can be used for OMR sheet printing only if the copier machine is giving good quality photocopies.
  • Please make sure the size of the photocopy is same as the original OMR sheet design.
  • Please make sure that the Index points are printed solid black and there is no black dust or line over the bubbles or near the index points.

General Precautions for OMR Prinitng

OMR Sheet Printing of Coloured OMR Sheets

  • Coloured OMR Sheets can be printed using Laser/inkjet printer or offset printing.
  • Only 2 colours should be used.
  • One colour Black is necessary. Second colour can be pink or orange or golden yellow.
  • Green or blue tones should be avoided.
  • Coloured OMR Sheets can also be printed using offset printing.
  • The sheets using tick marks or thin impression responses should be preferably printedn in 2 colours.
  • The sheets with bubbles having text label inside them should be preferabely printed in 2 Colours.
  • In case of Offset printing, the corner black index points are printed in both colours, such that the exactly overlap and there is no relative displacement i.e. zero-zero registration.

OMR Sheet Printing of Barcode/ OCR Serial No./ Stamped Serial No.

  • In case of stamped number printing, DO NOT spoil the sheet by stray ink marks. Stamped numbers cannot be read.
  • Only digital numbers or barcodes printied through variable data printing process can be read.
  • Barcode should be printed in 32 to 36 font size in black colour only.
  • OCR text for optical character recognition should be printed in 16-18 font size in black colour only.
  • OCR & Barcode fonts can be download from www.admengroup.com/support.htm




Instructions for OMR Sheet Scanning

  • Any Flatbed or ADF Scanner can be used for OMR answer sheet scanning.
  • Addmen OMR sheet scanner software correctly reads even rotated, skewed or distorted OMR sheets.
  • Keep the sheet holding plastic brackets in the OMR sheet scanner pocket close to prevent from unnecessary tilting, straying or tangling in the OMR sheet scanner.
  • Keep the scanning area wide enough so that the corner 4 index points are properly scanned and there is sufficient white space outside them.
  • Scan as "Image / Picture". DO NOT scan as "Document".
  • Save as BMP or TIFF file only. DO NOT save as JPEG/DOC/PDF.
  • Scan at any DPI between 100-200 dpi.
  • 100 dpi OMR sheet scanning is absolutely as accurate as higher dpi scanning so no need to scan at higher dpi.
  • DO NOT increase brightness or contrast unless guided. Scan at default settings.
  • For scanning OMR sheets with OCR or Barcode, scan at 150-200 dpi in greyscale or colour mode.
  • For scanning OMR sheets with photographs, scan at 100/150 dpi in Greyscale or Colour mode.
  • For scanning OMR sheets with thin tick marks, scan at 150-200 dpi in colour mode.

Scanning of B/w Sheets

  • Prefereably scan as B/W (1-Bit) image.
  • In B/W (1-Bit) mode the approx. file size of scanned A4 sheet is in range of 100-130 KB for BMP and 40-50 KB for TIFF.
  • Avoid scanning as B/W Photo (Grayscale) or Colour Photo (RGB) to keep file size minimum.
  • But you can scan as B/W Photo (Grayscale) or Colour Photo (RGB) also. It will also work only file size will be larger.

Scanning of Coloured Sheets

  • These instructions are for sheets with 2 colour printing or sheets with photograph pasted on them.
  • Prefereably scan as colour (RGB)image.
  • Avoid scanning as B/W (1-Bit) or Grayscale to keep photo clear.
