In a humid pressroom or when using water-based inks, standard sleeves can absorb moisture. This causes them to swell, changing their diameter and leading to critical print defects like dot gain and incorrect registration. The rotoSLEEVE Hydrophobic is the definitive solution to this problem.

This innovative sleeve features a special moisture repellent silicone surface that creates an impenetrable barrier. By preventing water from soaking in, our hydrophobic printing sleeves ensure absolute dimensional stability from the start of the print run to the end, making them the essential tool for high-quality printing with water-based inks.

The Advantage of Absolute Dimensional Stability

Prevents Sleeve Swelling: The core benefit. The hydrophobic surface creates a complete barrier against moisture, guaranteeing the sleeve's diameter remains constant throughout the entire printing process.
Guarantees Consistent Print Quality: By maintaining its exact diameter, our non-swelling flexo sleeves ensure consistent dot gain and perfect color registration, eliminating costly print quality issues.
Ideal for Water-Based Inks: This sleeve is specifically recommended for printers using environmentally friendly water-based ink systems, where moisture exposure is highest.
Durable and Reliable Barrier: The robust silicone surface is engineered to maintain its hydrophobic properties for a long service life, ensuring consistent performance job after job.
