Finding the Perfect Mark: A Comparison Guide
In the world of product branding and industrial coding, achieving a high-contrast, permanent black mark on plastic is often the "Holy Grail." However, not all lasers are created equal. Depending on your material and quality standards, the choice between Fiber and UV Laser technology can make or break your final product's look.
To help you decide, we ran a head-to-head test on common yellow plastic substrates. Here’s what we found.
1. Fiber Laser: The High-Contrast Powerhouse
Fiber lasers (1064nm) operate primarily through a thermal process. For many engineering plastics, this means the laser "carbonizes" the surface to create a deep, dark mark.
- The Result on Yellow Plastic: You get a vivid, intense black that stands out clearly.
- The Texture: Because it relies on heat, the marking will have a tactile, raised texture (foaming). It’s a mark you can feel with your fingertips, which can be an advantage for durability and grip.
- Best For: Industrial parts, durable tags, and high-visibility logos where "boldness" is key.

2. UV Laser: The "Cold Marking" Precision
UV lasers (355nm) are known for "Cold Marking." Instead of burning the surface, the high-energy UV beam breaks the molecular bonds of the plastic.
- The Result on Yellow Plastic: The mark is a refined dark gray to soft black. While the color may be slightly lighter than a Fiber laser, it offers a sophisticated, premium look.
- The Texture: The surface remains perfectly smooth and flat. There is zero damage to the material’s integrity, and the edges are incredibly sharp—perfect for high-density QR codes.
- Best For: Premium consumer electronics, medical devices, and aesthetics-driven packaging where a "flush" finish is required.

Which One Should You Choose?
The decision comes down to your product's Brand Identity and User Experience:
- Choose Fiber Laser if your priority is maximum visibility. If you want that logo to "pop" against a yellow background and don't mind a slight texture, Fiber is your workhorse.
- Choose UV Laser if your priority is precision and touch. If your product is handled frequently and needs to feel high-end and smooth, UV is the professional's choice.
Summary
We believe in the right tool for the right job. For those needing a bold, high-contrast black on yellow plastic, our Fiber series is unmatched. For those seeking surgical precision and a smooth-touch finish, our UV series sets the industry standard.
