High-Performance Carbon Blacks for Flexo, Gravure & Offset

Gravure Inks

Where Gravure Is Used

High-end laminate packaging

Decorative Laminates

Publication Gravure

Food wrap films

Barcode & coding films

Why Flexo Is Used

Highest image sharpness
Extremely high printing speed
Best for thin films and multi-layer laminates
Very thin and uniform ink layers

Industry Problems

  • Cylinder wear due to gritty pigments
  • Cell filling from high-structure blacks
  • Solvent retention & odor in food packaging
  • Lack of blue undertone → weak premium blacks
  • Viscosity drift during long, high-speed production
  • Film unevenness from poor dispersion
  • Cylinder wear due to gritty pigments
  • Cell filling from high-structure blacks
  • Solvent retention & odor in food packaging
  • Lack of blue undertone → weak premium blacks
  • Viscosity drift during long, high-speed production
  • Film unevenness from poor dispersion

Fundamental Requirements From Carbon Black

Low structure → Prevents cell plugging
Medium particle size → Low viscosity, fast drying
Low grit → Avoid cell scratches
Blue undertone → Protect expensive anilox and plates
Uniform aggregate size → Smooth film

What Carbon Black Must Deliver 

High-speed dispersibility
Stable rheology in NC/PU systems
High optical density with low loading
Controlled PSD to prevent “mottle”
Good solvent release behaviour
Minimal trapping in gravure cells
