Organoclay for Planographic Ink Applications
Advanced rheology modifiers specifically engineered for planographic printing inks. Delivering superior viscosity control, anti-settling properties, and consistent print quality for offset lithography applications.
Understanding Planographic Printing
Planographic printing, including offset lithography and lithographic processes, relies on the principle that oil and water don't mix. The printing surface is flat, with image and non-image areas on the same plane, differentiated by their affinity for ink or water.
This printing method demands inks with precise rheological properties to ensure consistent transfer, proper dot formation, and excellent print quality across high-speed production runs.
Key Printing Characteristics
- Flat printing surface principle
- Oil-water repulsion mechanism
- High-speed production capability
- Precise dot reproduction

Application Guidelines
Proper incorporation techniques and formulation guidelines to achieve optimal performance in your planographic ink systems.
Incorporation Method
Pre-gel Preparation
Disperse organoclay in a portion of the vehicle or solvent using high-shear mixing equipment.
Polar Activator Addition
Add polar activator (typically 30-40% of organoclay weight) to enhance gel formation.
High-Shear Mixing
Mix at high shear for 10-15 minutes to achieve complete dispersion and gel development.
Final Formulation
Incorporate the pre-gel into the final ink formulation with remaining components.
Formulation Tips
- Start with lower dosage and adjust as needed
- Ensure complete dispersion before adding pigments
- Monitor temperature during mixing process
- Test compatibility with specific resin systems
Storage & Handling
- Store in dry, well-ventilated area (0-30°C)
- Keep containers tightly closed
- 24-month shelf life under proper conditions
- Avoid exposure to moisture and humidity
