Fingerprint Optimization: Reducing Marks, Upgrading Texture

In daily life, the surface quality of products such as smartphones, computers, and automotive interiors often determines a user’s first impression. However, with frequent use, fingerprints and oil smudges tend to accumulate, diminishing both visual appeal and tactile experience—ultimately impacting overall user satisfaction.

Current Challenges:

IMR films (In-Mold Release) are widely adopted for surface finishing due to their design flexibility. Nevertheless, in real-world applications, fingerprint visibility and cleaning difficulty remain ongoing challenges. Achieving a balance between aesthetics, durability, and convenience has become an urgent issue in the industry.

Morita’s Solution: IMR Fingerprint Optimization Film

To meet market demand, we have introduced the IMR Fingerprint Optimization Film. Through innovative surface structure design and precise process control, this technology can:

• Significantly reduce fingerprint adhesion, making marks less visible
• Enhance cleanability, easily restoring a “like-new” feel
• Improve the overall user experience while keeping product appearance and texture consistently premium

This is not merely an aesthetic enhancement, but a comprehensive upgrade to product value and market competitiveness.

Technical Principles:

• Micro-Texture Design

  
  Creates fine surface “bumps and valleys” that use optical and tactile differences to reduce the visibility of fingerprints

• Reduced Contact Area

  
  Microstructures minimize the actual contact between fingerprints and the surface, lowering residue

• Random Dot Embossing

  
  Controlled dot size and spacing create matte or sandblasted textures, balancing aesthetics and functionality

In short:
“Fingerprint optimization” does not make fingerprints disappear completely; it reduces their visibility and makes cleaning easier, achieving a balance of durability, aesthetics, and convenience.

Application Value:

• Enhances overall surface appearance and premium feel
• Minimizes visual and tactile discrepancies caused by daily use
• Increases user satisfaction and brand value
• Broadly applicable across consumer electronics, automotive interiors, household appliances, and other industries
