Which coding method uses raised letters and/or numbers on packaging?

• A. Lithographing
• B. Embossing
• C. Stamping
• D. Engraving

Answer: (B)

Embossing creates raised letters and numbers on packaging by pressing a die into the material to form a relief. This elevation makes the characters stand out in height and can be felt by touch, which is exactly what “raised letters and/or numbers” describe. Lithographing prints onto a flat surface, so the result is flat; engraving carves into the surface, producing recessed lines rather than raised ones; stamping can leave marks but isn’t defined by creating true raised relief on packaging. So embossing is the method that best matches the idea of raised coding on packaging.
