Inks used for packaging, publishing, and industrial printing demand excellent rub resistance, gloss control, and stability. By incorporating micronized wax ink formulations, converters can improve durability, reduce smudging, and maintain print clarity.
Functions of Micronized Wax in Inks
Rub Resistance: Reduces ink wear and prevents image smearing.
Gloss Control: Offers uniform matte or semi-gloss finishes as desired.
Slip Improvement: Enhances scratch resistance and anti-blocking properties.
Product Characteristics
Particle size: 1–6 µm for smooth finishes and non-settling behavior.
Resin compatibility: Suitable with solvent-based, water-based, UV-curable inks.
Chemical stability: Inert under ink curing conditions.
Application Guidance
| Ink Type | Dosage (wt%) | Effect Achieved |
|---|---|---|
| Water-based flexo | 0.5–1.0% | Rub resistance, anti-set-off |
| Solvent-based gravure | 0.3–0.8% | Smoothness, anti-scratch |
| UV-curable screen inks | 0.5–1.2% | Gloss control, improved slip |
Results in Practice
Rub resistance (DIN 53160) increased by 30%.
Gloss reduced from 90 GU to 60 GU at 60° for matte applications.
Ink film integrity improved during folding and high-speed drying.
Using micronized wax ink formulations helps printers meet high standards of durability and appearance across packaging and publishing industries, without affecting color intensity or adhesion.
