UV Dryers for Offset Printing — Sheet-Fed Curing Systems

Offset printing uses oil-based inks that dry through evaporation or absorption, while UV printing uses UV-reactive inks cured instantly by ultraviolet light. UV offset printing combines offset's high-quality image reproduction with UV curing's immediate dry-to-touch results, enabling faster turnaround, better ink adhesion on non-porous substrates, and reduced drying time between passes.

UV ink cures almost instantaneously — typically within fractions of a second when exposed to a sufficiently powerful UV light source. Fannon Products' UV LED curing systems operate at 395–405nm with 16W/cm² intensity, enabling full curing at press speeds without slowing production. Cure time depends on ink formulation, substrate type, and lamp intensity.

UV resin relies on ultraviolet light to initiate the curing reaction. On a cloudy day, ambient UV radiation is significantly reduced, making outdoor solar curing unreliable and inconsistent. For printing applications, dedicated UV LED curing systems like Fannon Products' press-mounted units are essential, as they deliver a controlled, consistent UV output regardless of ambient lighting or weather conditions.

Fannon Products' UV LED curing systems operate at a 395–405nm wavelength range — the optimal spectrum for curing most UV offset and screen printing inks and coatings. This range ensures deep, consistent ink cure across the full print width while maintaining compatibility with the majority of commercially available UV ink formulations.

Fannon Products offers UV LED curing modules in three standard sizes: 3 inch (80 x 40mm emitting window), 6 inch (160 x 40mm), and 9 inch (240 x 40mm). Each module delivers a consistent 16W/cm² power intensity and is air-cooled for simplified installation, making them suitable for a range of press widths and configurations.

Yes. Fannon Products' UV LED curing systems are designed for standalone installation and can be integrated into existing offset printing press setups. The modules feature 24 VDC or dry contact transport interlock connections, enabling seamless press synchronization. Available in 120V and 220–230V configurations, they are compatible with standard North American and international electrical systems.
