OMR Sheets – Optical Mark Recognition Sheets

OMR Sheets are pre-printed forms containing bubbles, checkboxes, or blocks for marking responses.

These marks are read by OMR software to produce digital data for evaluation.

Other names: OMR Answer Sheet, MCQ Sheet, ORS (Objective Response Sheet), Bubble Sheet.

With Addmen OMR solutions, you can design, print, and scan your own OMR sheets, avoiding the need for expensive pre-printed sheets.

Paper Used for OMR Sheet Printing

• White, smooth, uncoated paper

• Size: A4 or Letter

• GSM: 70–100

• Avoid colored, textured, or recycled paper to ensure accurate scanning

Laser or Inkjet OMR Sheet Printer

• Laser Printers: Suitable for high-volume exams; provide sharp and consistent printing

• Inkjet Printers: Suitable for low/medium volume; ensure non-smudging ink

• Digital Presses: Professional-grade, large-scale printing

OMR Sheet Printing on Offset

• Ideal for large-scale printing

• Produces uniform high-quality sheets

• Suitable for exams with thousands of candidates

Two-Colour OMR Sheet Printing

• Highlight specific sections without affecting scanning accuracy

• Recommended: Black + Pink/Yellow

• Avoid Blue or Green

• Used for marks, section headers, or instructions

Barcode & OCR Printing on OMR Sheet

• Barcode Fields: Digital printing, font size 32–36, black color

• OCR Fields: OCR-friendly fonts, font size 16–18, black color

• Avoid handwritten or stamped numbers

• Barcodes identify sheets; OCR captures printed codes

Instructions for OMR Sheet Scanning

• Scan as Image / Picture — DO NOT scan as Document

• Preferred file formats: BMP or TIFF

• Resolution (DPI): 100–200

• Color Mode:

• B/W for standard sheets

• Color for sheets with images or highlights

• Alignment: Ensure all four corner index points are visible

• Addmen OMR software auto-corrects skewed or rotated sheets

Scanning of B/W Sheets

1. Preferably scan as B/W (1-Bit) image

2. In B/W (1-Bit) mode, the approximate file size of scanned A4 sheet:

• BMP: 100–130 KB

• TIFF: 40–50 KB

3. Avoid scanning as B/W Photo (Grayscale) or Colour Photo (RGB) to keep file size minimum

4. You can scan as B/W Photo (Grayscale) or Colour Photo (RGB); it will work, but file size will be larger

Scanning of Colour Sheets

• Colour scanning can be used if sheets have photos or two-color highlights

• File size will be larger than B/W scanning

• Ensure proper alignment and index points for accurate detection

ADF / Flatbed Scanning

• Flatbed: Suitable for small batch scanning; ensures high accuracy

• ADF (Automatic Document Feeder): Suitable for large-volume scanning; supports duplex sheets and batch processing

• Batch Processing: Addmen OMR software handles multiple sheets automatically

Recommended ADF Scanners:

Table

Scanner Model	Speed (ppm)	Notes
HP ScanJet Pro 3500 f1	25 ppm	Flatbed + ADF, reliable daily use
Brother ADS-3100	40 ppm	High-speed batch scanning
Epson DS-530II	35 ppm	Duplex ADF, two-sided sheets
