Bar code image generation is an essential part of modern-day manufacturing. Everyone is familiar with those inscrutable black lines inside the small white box on just about every product available. But what are they? What do they stand for? How do they work?

A professional manufacturer will know the answers well. Universal Product Code (UPC) bar code image generation originated as a way to help grocery store checkout. Other retailers saw the wisdom of the system, not just for checkout, but also for tracking inventory. The system spread quickly.

UPC numbers are issued by the Uniform Code Council (UCC). They consist of two parts: Machine-readable bar code and a 12-digit UPC number. The first six digits are the manufacturer's identification number. The next five digits are the item number, determined by the manufacturer to help track different products. The last digit is a "check digit"--it guarantees a UPC number has been scanned properly, using a simple math equation involving the rest of the numbers in the code.

Bar Code Image Generation Must Be Done Right

A bar code is only really useful if it can be read the first time it is scanned. Bar code image generation should be performed by professionals who know how to create, handle, and reproduce master images. You want your product to beep through cleanly on the first sweep.
