It can be difficult to provide the many details of unique identification basics in just three or four paragraphs. UID marking procedures are complex and consist of many crucial rules. These basic rules focus on every aspect of the item marking process from material selection, the printing or marking methods, reader technology, registration, and data verification processes. MIL SPEC 130 is the recommended standard for DOD unique identification marking.
Basics relating to material selection
According to MIL SPEC 130, metal plates like aluminum, stainless steel and other non-metallic counterparts, like polyester nameplates, are approved. This standard permits the usage of engraved, cast, and stamped nameplates along with laminated, photosensitive, and even laser generated plates. For small items (that offer no space to very little space for marking) these plates can be attached in the form of a tag or cable band.
Basics relating to the marking process
MIL SPEC 130 allows a vast number of marking procedures. The most popular marking applications are given below.
• Metal stamping is the most recommended marking method. Metal and non-metallic plates that can toil the stamping pressure are allowed to use this marking procedure.
• Other than metal stamping, some recommended methods include programmable stylus indenting, engraving, chemical etching, embossing, laser marking, industrial inkjet printing, and others.
• Metal and rubber tags, as well as permanent decals, are allowed when other methods fail to create unique item marking.
The product suppliers and manufacturers have to undergo registration. They have to provide a unique manufacturer’s or enterprise number along with part number and product number. The manufacturer has to provide details of the marked item during data invoicing. This data is often transmitted through a wide area workflow.
Data formatting basics
Both types of 1D data matrix and 2D data matrix are allowed during the UID product marking process. However, 1D data format is only permitted only when 2 D data format is not applicable. The standard permits both human readable and machine-readable data. For each type of data, it is essential to pass through the data validation and data verification process. Data validation is done using bar code verifiers. Data verification is done to ensure printing quality and other necessary aspects of unique identification. It is important to use specific types of barcode readers and scanners recommended by these regulations.
