OMR Sheets have black colour index point which are at the corner of the sheet.

The index point is the most important parameter of an OMR Sheet.

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 picking candidate name and other details)
• Image Block (for geting candidate picture & signature)
• OCR Block (for geting Form/Sheet No. from pre printed text)
• Barcode Block (for geting Form/Sheet No.)

OMR Sheet Paper

• Normal 70gsm A4 copier paper commonly available in the market can be used to print.
• There is no need to use thick paper. If you want thick paper can also be used.
• Both Thin or thick paper are 100% accurate.
• Only white paper should be used.
• 18"x23" size paper can be used for offset printing 4 sheets together.
• Thickeness of paper is only increased if the

OMR Sheet Colour

• Only single black color printed sheets can be used.
• Our OMR Software does not need 2-color print.
• 2 colour sheets can also be printed if desired.
• In case of 2 colour sheets, one colour is Black and second colour is Pink or Orange.
• The sheets with bubbles having text label inside them should be preferabely printed in 2 Colours.

OMR Prining Process

For printing use the CorelDraw file of the OMR design exported by the software.

This CorelDraw file can be editted to add your organisation Name, Logo and other necessary information without disturbing the technical OMR area i.e. the index points and circles.

PDF file should be used only for viewing or prining if CorelDraw is not available.

Laser Printing >

• OMR Sheets can be printed using a Laser Printer or rezograph.
• Set the laser/inkjet printer page to A4. Mostly standard page is set as ‘Letter’. change it to A4.

Offset Printing >

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

Photocopy Prinitng >

• Photocopies of OMR Sheet can also be used if the machine is giving good quality photocopies.
• Please make sure the size of the photocopy is same as the original.

Precautions for OMR Prinitng

• DO NOT alter the Size of the sheet format.
• Print to centre of page so that there is sufficient white space outside 4 index points in all 4 corners.

Index Points >

• DO NOT remove index points.
• DO NOT change location of index points as exported by the software.
• In any method of printing: Laser, Offset or Photocopies, ensure that 4 Black Index Points on 4 corners of sheet are properly printed.
• The index points should be printed Solid & Dark in Black colour. If the index points are not properly printed, they will not be scanned properly and it will give trouble while reading.
• DO NOT print anything else outside or close to the Index points.

Circles/Boxes/Bubbles >

• DO NOT change location of circles/boxes as exported by the software.
• DO NOT increase the line thickness of bubbles. The line thickness of the circles is kept thin to avoid interference in reading. If you make the bubble outlines very thick the software might read all bubble edges as response because ultimately software is made for reading dark areas.

Text Labels inside Bubbles >

• DO NOT increase the font of text labels printed insde the circles.
• DO NOT use Bold or Large fonts. The font should be as small and thin as possible.

General Instructions for OMR Scanning

• Scan answer sheets using any Flatbed or ADF Scanner.
• Addmen OMR Software correctly reads even rotated, skewed or distorted OMR sheets. But we should keep the sheet holding plastic brackets in the scanner pocket close to avoid the sheet from straying and prevent from tangling or unnecessary tilting in the 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 100 dpi. If not available in scanner, scan at 150 or 200 dpi and correspondingly change the dpi settings in settings menu.
• 100 dpi 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.
• After scanning your omr sheet should look like this scanned image.

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.

Filling the bubbles OMR Sheets

• Use of Pen/Pencil depends on the rules set by the exam body. Carefully read the instructions given on the sheet before fillng.
• OMR sheet has to be filled using Blue/Black Ball Pen or HB pencil.
• DO NOT use Ink Pen as it might bloat or spill.
• DO NOT underfill or overfill the OMR circles. Avoid partial filling or spilling out.
• First fill the circles/boxes in the OMR sheet completely and then darken the filled circles/boxes.
• Completely darken the respective circle for your response.
• Please fill the appropriate OMR circles with due care. Avoid over-writing on OMR Sheet.
• Mark multiple bubbles only in case of MCQs or multiple choice questions. If you mark more than one circle in a single choice question the answer will be considered as being wrong.

Type of marks detected by OMR Software

Dirt and Scratches do not affect OMR Software

Restricted Areas on OMR Sheets

• There are ‘DO NOT WRITE’ areas demarcated on some OMR Sheet. Please do not write or mark on the demarcated areas.
• All OMR sheet have index points that are crucial to their functioning. Do not mark anything on or near Index Points or Timing Track of OMR sheet.
• Any change in Timing Track and OMR sheet identification block will lead to rejection of the OMR sheet and no result will be generated for such OMR sheets.
• DO NOT make any stray marks on the OMR Sheet.
• Use the area for "Rough Work" on sheet only if expilicitely provided.

Erasing on OMR Sheets

• Most examinations do not permit the use of Pencil and thus no provision to erase an option already marked.
• Erasing depends on the rules set by the exam body. Carefully read the instructions given on the sheet before fillng.
• If use of pencil is allowed in your exam, then you may change a mark by completely erasing the wrongly filled circle. But the erasure should be complete and without any smudges as partially erased mark may lead to wrong reading by the highly sensitive OMR Software.
• DO NOT use whitener or blade to hide marks on OMR Sheet.

Handling the OMR Sheets

• DO NOT pin or staple anything with the OMR Sheet.
• DO NOT punched or tie the OMR Sheet.
• DO NOT fold or crush the OMR Sheet.
