Product Marking (DPM)
What is direct product marking or DPM?
is a marking process that directly applies a UID mark to a product.
DPM processes include industrial ink jet printing, laser etching,
dot peening and electro-chemical etching. Label affixing is
not a direct product marking process.
We currently use rubber stamps to mark our product information
but are now required to direct product mark our parts with Mil-Std
130 UID compliant 2D codes. What process alternatives are available
laser etching, dot peening, electro-chemical etching and labeling
are all process alternatives capable of meeting Mil-Std 130
requirements. The first step is to review your contractual requirements
to see if a particular process has been identified by your customer.
no specific process has been defined by your customer, the next
step is to determine whether an additive or subtractive process
is preferred. An additive process is one in which the UID mark
is added to your part. Industrial ink jet printing and labeling
are additive processes. A subtractive process is one where material
is removed from the part to generate the UID mark. Examples
of subtractive processes are laser etching, dot peening and
closest process to rubber stamping is industrial ink jet printing.
Most industrial ink jet printing systems are digital ink jet
printing systems capable of printing alpha-numeric text, bar
codes, 2D codes, serial numbers and logos. Selecting the right
ink jet printer, ink and system configuration is crucial to
implementing a robust, reliable ink jet marking system alternative
to rubber stamping.
