Can the code be read if only 10% of the image remains?
Sometimes yes, a code can still be read from a very small surviving fragment. But what matters is not only the percentage that remains; it is also which part remains and what other information is available.
If the surviving 10% includes useful parts of the finder pattern and the internal grid, and the GTIN or product structure is already known, the chance of success may still be meaningful.
In practice we have seen recoveries from roughly 10% of the image and, in special projects, even from around 2–4%, but only when strong contextual information was available.
This does not mean the software “guesses” the answer magically. It combines the fragment with geometry, ECC checks, known GTIN, serial expectations and sometimes shipment context.
That is why even a very damaged label is still worth sending for review. A small fragment can contain more value than it seems.
The opposite is also true: a symbol that looks mostly intact may still fail if the key areas are misread.
