Definition
A numerical indicator of surface energy (dynes/cm) used to predict ink/adhesive wetting on films.
Applications
- Pre-press QC
- Incoming film inspection
- Troubleshooting adhesion problems
Benefits
- Predicts print adhesion risk
- Improves process consistency
- Reduces rework and scrap
Industry Examples
- Medical: verifies treated surfaces before laminating sterile barrier webs.
- Industrial: ensures inks adhere to HDPE liners used in harsh conditions.
- Electronics: verified prior to printing to ensure ESD caution markings adhere to static-shielding bags without rub-off.
FAQ
Q: Is higher dyne always better?
A: Not always—too high can attract contamination; target the process need.
Q: How is dyne measured?
A: Dyne pens or lab contact-angle measurements.
