Carbonless OMR sheets are a specialized solution used in Optical Mark Recognition (OMR) systems to capture and verify candidate responses while providing full transparency. These sheets consist of two or three parts: the first copy, which is retained by the examination authority for evaluation, and the second (or third) copy, which the candidate takes home for reference. This process ensures that candidates receive a direct replica of their submitted answer sheets, fostering trust and accountability in the examination process.
The carbonless OMR sheet has a unique construction that allows the creation of an exact replica of the marked answers:
Two or Three Parts: The first part is a thicker sheet that remains with the exam body for grading, while the second part is a thinner sheet that contains a carbonless coating, which the candidate takes home.
Carbonless Coating: When a candidate marks their answer by filling a bubble with a pen or pencil, pressure from the mark creates a black impression on the second sheet (the candidate's copy).
Transparent Evaluation: This method ensures that candidates have a faithful copy of their answer sheet to verify if there is any discrepancy between their expected marks and the final results. If any discrepancies arise, candidates can compare the marks on their own sheet with the evaluation report.
By providing candidates with an exact replica of their answer sheets, Carbonless OMR Sheets eliminate any doubts or mistrust. If candidates believe they have been awarded fewer marks than expected, they can raise a claim and validate the results against their own sheet.
The carbonless coating creates an exact copy of the marks on the candidate’s sheet, making it impossible for anyone to alter the data once it's captured. This guarantees data security and reduces the possibility of manipulation or errors in grading.
Unlike traditional carbon paper, carbonless OMR sheets don’t require additional paper or chemicals. This makes them a more environmentally friendly option, as the process produces fewer waste materials while maintaining the same high level of data accuracy.
Using carbonless OMR sheets ensures that there is no room for complaints about mark tampering or incorrect evaluation. The transparent process enables candidates to trust the examination results while protecting exam authorities from unwarranted complaints.
Addmen provides high-quality Carbonless OMR Sheets made from top-grade materials to ensure accurate data capture and long-lasting durability:
Paper Thickness: Typically, the first part is 105 gsm (thicker sheet) and the second part is 65 gsm (thinner sheet), with a special chemical coating on the second sheet.
Optional Thickness: For certain applications, the paper may be made from 90 gsm for both sheets to meet specific requirements.
Coating Technology: The second part of the sheet is treated with a special carbonless coating, which reacts to pressure exerted by the candidate's marking to produce a clear, legible copy.
Dual Color Printing: To prevent confusion, both parts of the OMR sheet are printed in different colors, so the candidate knows which sheet to take home.
The cost of Carbonless OMR Sheets varies depending on several factors:
Quantity: Larger quantities generally reduce the per-sheet cost.
Customization: Special features such as unique numbering, barcodes, or litho codes will affect the pricing.
Two-Part vs. Three-Part Sheets: Three-part sheets are typically more expensive due to the added complexity.
