How to improve ink adhesion on tough surfaces

Action	Impact
Use high-adhesion or oil-penetrating ink	Designed to bond through surface films
Pre-treat surface (wipe or heat)	Removes residue or moisture
Lower line speed slightly	Allows more drying/contact time
Increase printhead proximity (2–5 mm)	Reduces drop scatter and overspray
Test with different drying agents	Acetone/ethanol bases dry faster than MEK on some surfaces

Struggling with ink that wipes off or won’t stick? This guide helps you get better adhesion on challenging materials like rubber, HDPE, and oily metals.
