Marking Quality
Finally, there are also specifications regarding the marking quality of an MRI.
- Linear Bar Code: Unless otherwise specified in the contract or order, ISO/IEC 15416 is the protocol for measuring the print quality of a linear bar code.
- Data Matrix Symbol: There are a number of protocols that can be used for measuring the print quality of a data matrix symbol, at the supplier’s discretion. This includes ISO/IEC 15415, AIM DPM-1-2006, or SAE AS9132. If a data matrix symbol is ever found to be erroneous, unreadable, or otherwise unacceptable, two diagonal lines should be used to cross out the symbol in addition to two other lines (one horizontal, one vertical) through the two interrupted frame lines.
