OMR – Optical Mark Reader | What is the function of OMR – Best Information

What is OMR (Optical Mark Reader) The full names of OMR are Optical Mark Reader. It is a device that checks for the presence of a pencil or pen mark on any paper. This is the latest way to check your exam answer sheet. Questions on these exam questionnaires are optional. In this case, the candidate must pencil out the desired answer box from the options given as an answer to the question.

The answer sheet marked in this way is highlighted and the reflected light is checked. The intensity of the light reflected from that part of the answer sheet that the candidate marked with a pencil is less than the intensity of the rest of the sheet. This device can only be used to check printed cards, boxes placed in the army in a fixed location, and boxes marked or filled with pencils. OMR- Optical Mark Reader data transfer speeds are only 200-250 pages per minute.

What is OMR (Optical Mark Reader )

What is OMR – Optical Mark Reader is an acronym for optical mark recognition. OMR forms are used to collect data. Preparing this type of form involves several important steps.

Obviously, you need to carefully determine the type of data you need to collect and lay out your questions in a clear and easy-to-understand format. Then these questions are sent to the designer to find out the best way to present them in an attractive layout. Designers need to understand how the Optical Mark Reader scanner reads this information and correctly place the answer bubble associated with the question on the form so that the scanner can read the information accurately.

Once the form design or layout is approved by the customer, the electronic form is moved to the printing stage. It is also important for printers to understand the importance of consistently arranging printed sheets according to their layout.

The layout is based on a grid system determined by the specific parameters of the scanner. The two basic elements of this grid are timing marks and reaction bubbles. Timing marks appear in the columns on one edge of the sheet. These rectangular markings will appear on the scanner as the sheet passes through the scanner.

Timemarks determine when to start and end observing the corresponding bubble row and record the results. In the normal format, the sheet can contain up to 48 bubbles. In order for the scanner to know which bubble to look for, the scanning software must create a file called the scan definition before the actual scanning process. This scan definition notifies the scanner of one or more bubbles in the grid, determines if they are filled, and records the assigned values.

These values ​​or results are added to the Excel type data file as each form is scanned. When the scan is complete, the results are aggregated using dedicated reporting software. Scanned data and tabular results can be potentially unreliable if the quality of the original scanned form is compromised by disruption to the layout or printing process.

OMR(Optical Mark Reader) is a great time-saving process for collecting data, but it can be a big headache if not done correctly. Before jumping into an OMR assessment project, it’s important to do some homework to get a good understanding of how OMR works. There are many excellent resources on the Internet that can assist you with one or all related steps. Google for OMR Data Collection Services for a comprehensive list.

What is the Difference OMR Readers and OMR Software

So did you finally think you needed a way to automatically mark up exams and surveys? You may have already read about OMR (Optical Mark Recognition or Optical Mark Recognition), a computerized imaging device process that detects marks on used paper foam. Hmm.

OMR is not a new technology and has been widely used since the 1960s. In the 1990s, many changes were made to both OMR-related costs and features. Especially in the 90’s, Optical Mark Reader software was adopted over traditional OMR- readers. Both have the same basic purpose, but the OMR- reader solution is quite different from the OMR- software / scanner solution. Before deciding to buy either, you need to be familiar with what the difference is.

Optical Mark Reader Leader

Once a very expensive machine, OMR readers have become very cheap over the years and are now very affordable for most organizations. The most important thing to remember with OMR readers is that they are not image scanners. The Optical Mark Reader has several LEDs (Light Emitting Diodes), often 40 to 50 of which illuminate the passing foam at once. This light reflection helps the OMR reader’s sensor determine if the numbers are placed as bubbles.

Most OMR readers read professionally printed forms and have a timing track that helps the reader determine the type of bubble the machine is reading. The Optical Mark Reader also has adapters for barcodes detection to assist in the automated process of matching form responses to responders.

Advantage Points: –

  1. The Optical Mark Reader may have a separate hopper for automatically rejected forms.
  2. Most OMR software applications use silhouette extraction and are sensitive to nearby objects, allowing you to pack more bubbles into one OMR reader form than can be read by Optical Mark Reader software.
  3. Faster than low-end document scanners.

Disadvantage: –

Speed ​​was once the biggest advantage of OMR readers, but high-end document scanners like the Canon DR-X10C have recently caught up with OMR reader speeds at similar prices. Therefore, speed is not always beneficial to Optical Mark Reader.

  1. Optical Mark Reader are much more expensive than document scanners / software solutions.
  2. Optical Mark Reader cannot record handwriting (ICR) or typed data (OCR).
  3. Optical Mark Reader forms are not as customizable as software forms.
  4. You can’t easily print your own customized form because the bubbles don’t always match the timetracks and columns. You usually need to buy an Optical Mark Readerform.
  5. Digital copies of the form are not available.
  6. The form cannot be skewed automatically. form must be filled out directly.
  7. You can’t read pen marks or pay more for built-in support without an ink reader.
  8. You will not be able to read the barcode unless you add a barcode adapter or pay an additional fee for the built-in adapter.
  9. Optimal application:
  10. A large Optical Mark Reader project where you don’t want to rearrange unfamiliar pages.
  11. Those who want high-density mark foam.
  12. Those who already have an existing Optical Mark Reader and do not want to retrain their staff to use OMR software.


OMR Software – An image scanner is required for software-based OMR to work. In other words, OMR software extracts mark data from computer images such as TIFF files. Image scanners are usually flatbed scanners or document scanners. Some OMR software applications can also read data from images taken with digital cameras and fax machines. Keep in mind that the functionality and implementation of Optical Mark Reader software applications is very different. These should also be compared when choosing an OMR software application.

Advantage Points:

  • The form is customizable and can be replaced during scanning.
  • Images scanner can be used for more than just Optical Mark Reader scanning.
  • The OMR software form does not need to be placed as accurately as the Optical Mark Reader form.
  • You can optionally read barcodes, handwriting information (ICR), and input information (OCR).
  • You can keep a digital copy of the form.
  • Cheaper than Optical Mark Reader.
  • You can optionally unskew automatically. You can automatically rotate the form to straighten the image.
  • Easy to read blue pen and pencil.
  • The Optical Mark Reader software can read any supported barcode type.
  • Improved automation with automatic identity generation / solution and form personalization.


  • Inexpensive document scanners may be able to hold only a small amount of paper (50-100 pages).
  • Inexpensive document scanners have a low duty cycle (about 3000 pages per day)
  • As an Optical Mark Reader leader, bubbles cannot be brought close.
  • Unrecognized documents cannot be physically sorted.
  • Optimal application:
  • All except the above cases.

OMR software has consumed much of the Optical Mark Reader hardware market over the last decade due to its flexibility and power. However, the market for OMR readers still exists and will continue to exist until low-end document scanners reach the speed of average OMR readers. It exists until someone develops a way to automatically sort unrecognized forms.

If you are considering an OMR leader, the best advice is to determine if you are one of the most suitable Optical Mark Reader leaders. It also compares the price of an OMR reader relative to the number of forms processed with the cost of one or more document scanners that combine the right speed and duty cycle with the right OMR software system.
