Why Flexo Is Used

Consistent print quality
Ideal for paper-based substrates

Works with oil-based, heatset, and coldset chemistries

Industry Problems

  • Rheology instability → poor gloss
  • Rub-off issues (insufficient film strength)
  • Slow wetting in oil-based binders
  • High emulsification in sheetfed
  • Tint strength inconsistency leading to color mismatch

Fundamental Requirements From Carbon Black

Medium particle size → Prevents cell plugging
Low structure → Low viscosity, fast drying
Oxidized surfaces → Avoid cell scratches
Clean morphology → For premium packaging
Stable undertone → Smooth film

What Carbon Black Must Deliver 

Balance between yield value & flow
Long-term rheology stability at 30–50°C
High rub resistance
High tinting strength for lower pigment loading
Smooth ink-water balance control
