OCR vs. OCV: A Clear Guide to Character Inspection With KEYENCE Vision Systems
Every mark matters. Lot numbers, expiration dates, and serial numbers all have a role to play in making sure traceability, quality control, and compliance standards are upheld. There are several ways to inspect characters, but not all methods are created equal.
Optical Character Recognition (OCR) reads characters, and Optical Character Verification (OCV) makes sure they are legible. We’ll go through how OCR and OCV are different, and how KEYENCE vision systems bring both performance and usability to the character inspection game.
The Critical Role of Character Inspection in Modern Manufacturing
Character inspection goes beyond simply 'reading' numbers or text. The information printed on parts, products, or even food items is often directly linked to crucial details such as serial numbers, expiration dates, or other vital product information. If this text or these numbers are illegible, it can result in costly recalls, food waste, and compliance violations.
The stakes are even higher in industries like pharmaceuticals, where product quality is directly tied to an individual’s health. Missing, incorrect, or illegible information on medication can lead to severe consequences.

Understanding the Nuances: OCR vs. OCV
Machine vision OCR (Optical Character Recognition) is designed to identify and read printed or marked characters. It “decodes” letters and numbers from an image and converts them into usable data.
Machine vision OCV (Optical Character Verification), on the other hand, checks whether a printed or marked character matches an expected pattern. Instead of “reading,” OCV is about verifying accuracy, completeness, and legibility.
Key Distinction: OCR answers “What does this say?” while OCV answers “Is this correct?”
Overcoming Manual Inspection Pain Points With Automated Character Reading
Manual inspection is known for being slow, inconsistent, and extremely prone to human error. These issues are multiplied when the characters are either faintly printed or on curved or shiny surfaces that make them harder to read. Also, it is important to remember that human performance declines over time; inspection quality at the end of a shift is rarely as sharp or consistent as it is at the beginning.
Automated character reading has many advantages over manual inspection. Automated OCR vs OCV powered by vision systems eliminates:
- Operator fatigue and subjectivity
- Misreads due to environmental factors (dust, glare, lighting shifts)
- Bottlenecks caused by random sampling instead of 100% inline inspection
