Which marking method is considered best for direct marking?

• A. Ink jet
• B. Hand engraving
• C. Dot matrix label
• D. Laser etching

Answer: (A)

Direct marking aims to apply clear, legible information directly onto the part’s surface without using separate labels or tags. Ink jet marking is the best fit here because it can deposit readable characters, barcodes, or graphics directly onto a wide range of materials and shapes as parts move along a production line. It’s non-contact, so there’s no risk of damaging delicate surfaces, and it’s fast and flexible—easy to change data via software for different lots, which is ideal for high-volume marking and traceability. With proper inks and curing, the marks stay legible without added labels, making it a practical choice for direct surface marking.
