In UV printing the ink bonds directly to the substrate, so ensuring good adhesion is essential. Even the most advanced printer and highest quality ink won’t deliver reliable results if the ink fails to bond properly to the surface beneath it. This is where Roland ECOUV Primer plays an important role, especially when working with traditionally hard-to-print materials.
Designed as a dedicated UV adhesion promoter, the Roland ECO-UV5 primer helps Roland UV ink anchor securely to challenging substrates, reducing costly failures, lowering waste and expanding the range of profitable materials a print business can confidently work with.
Why Adhesion Fails On Certain Materials
Not all surfaces are created equal. Many modern materials are deliberately engineered to be non-porous, low energy, exceptionally smooth and chemically resistant.
While these properties are great for durability, they make it difficult for ink to stick to the surface. Without correct UV print preparation, you’ll likely experience peeling, flaking, scratching and lamination failure more often with your products.
Substrates that regularly cause adhesion challenges include glass, acrylic, PVC, polypropylene, polycarbonate, aluminium and coated metals and plastics
What Is Roland ECOUV Primer?
Roland ECOUV Primer is a liquid coating applied to a substrate before UV printing. It works as a chemical bonding layer between the material and the ink. Once applied and flashed off, it creates a surface that allows Roland UV ink to lock into place rather than sit loosely on top.
The Roland ECO-UV5 primer has been specifically formulated to work seamlessly with Roland’s UV ink chemistry, ensuring consistent results without compromising colour, image integrity or curing performance.
How Roland ECOUV Primer Enhances Adhesion
At a technical level, the primer alters the surface energy of the substrate. Many difficult materials naturally resist wetting, which prevents inks from forming strong bonds. The primer resolves this by:
● Increasing surface energy
● Creating microscopic bonding sites
● Neutralising chemical resistance
● Improving ink spread and anchoring
Once the primer has been applied and allowed to flash off, Roland UV ink adheres far more aggressively during curing, producing prints that resist scratching, flexing and environmental wear.
When Should You Be Using A UV Adhesion Promoter?
You don’t always need a primer for every job. However, a UV adhesion promoter like Roland’s becomes strongly recommended when:
1. Printing on Plastics
Materials such as polypropylene and polycarbonate are notoriously difficult to print onto consistently without primer.
2. Working with Smooth Non-Porous Surfaces
Glass, polished metals, coated boards, and acrylic all benefit significantly from the use of the Roland ECO-UV5 primer.
3. Producing High-Wear Graphics
Items such as industrial panels, control interfaces, dashboards, labels, and product branding exposed to handling or abrasion require superior adhesion performance.
4. Applying Second Surface or Reverse Prints
Backlit acrylics, glass signage, and protected reverse prints place additional demand on ink bonding strength.
The Role Of ECOUV Primer In UV Print Preparation
ECOUV primers play an essential role in UV print preparation and are important for achieving consistent, professional results. Preparation should include cleaning the substrate thoroughly, removing dust, grease and residues, applying primer where required allowing sufficient flash-off time and printing with the correct curing profile.
Skipping any of these steps increases the risk of print failure, rework and customer dissatisfaction. The primer integrates neatly into production workflows without adding significant time, yet the performance gains are substantial.
How ECOUV Primer Improves Production Efficiency
While primer might seem like an additional extra step, it actually delivers measurable production efficiency benefits:
● Less rework - Fewer failed prints due to adhesion loss
● Reduced waste - Fewer rejected substrates
● Higher confidence on premium materials - Enabling higher-value jobs
● More consistent finishing - Improved lamination, cutting and handling performance
For print businesses producing short-run custom work, architectural graphics, POS displays and branded components, the primer pays for itself very quickly.
Compatibility With Roland UV Consumables
One of the major advantages of using Roland UV consumables is system-level compatibility. The Roland ECO-UV5 primer is engineered to work specifically with Roland UV inks, printheads, curing profiles and printer firmware.
This ensures predictable performance across different production runs, substrates, and environmental conditions. Mixing third-party primers with genuine Roland UV consumables can introduce risks, including inconsistent bonding, contamination or long-term print durability issues.
Why Adhesion Is A Profit Issue, Not Just A Print Issue
Poor adhesion isn’t simply a technical nuisance, it can impact your profitability too because failed adhesion leads to material wastage and an increase in reprints. It can also delay installations and worse still, lead to client complaints – the last thing you want when you’re trying to build a reputation as a quality printer.
By treating UV print preparation as a critical production stage and using Roland ECOUV Primer correctly, you protect both your output quality and your profit margins.
