UV Printing Frequently Asked Questions
UV Printing
UV printing is a digital printing process that uses ultraviolet (UV) light to instantly cure special inks as they’re printed. Instead of drying, the ink hardens on contact, creating sharp, durable, and vibrant prints. Because it cures instantly, UV printing works on almost any surface — plastics, glass, metal, wood, acrylic, and others — and supports both flat and curved items.
This technology is perfect for direct-to-object printing, making it ideal for short runs, customization, and fast production in signage, packaging, and promotional products.

High-gap (High Throw) UV printing allows a UV printer to jet and cure ink from farther away than a traditional UV printer allows — ideal for curved or uneven surfaces like mugs, bottles, and industrial parts.
Traditional printers need a tight gap between the print head and surface. High-gap printers, however, use advanced print heads, UV inks, and powerful curing systems to maintain precision from a greater distance. The result: clean, durable prints on objects standard printers can’t handle.

An inkjet printer creates images by spraying tiny droplets of ink onto a surface with extreme precision. It prints directly from digital files — no plates or screens required — making it fast, flexible, and easy to customize.
In industrial UV printing, inkjet printers use UV-curable inks that harden instantly under UV light, allowing direct printing on glass, metal, wood, and more.
Advanced Ricoh print heads (used in IDS printers) ensure accurate color, fine detail, and consistent results, even on curved surfaces.
A printhead is the part of an inkjet printer that sprays tiny droplets of ink onto a surface to form an image. It controls droplet size, placement, and speed — determining how sharp and consistent the print looks.
In UV printers, the printhead works with UV-LED curing systems that harden ink instantly. IDS printers use Ricoh Gen6 printheads, known for long-distance jetting, fine detail, and high precision.
A print bed is the platform that holds your item steady during printing. There are three main styles of print bed: flatbed, rotary or cylindrical, and conveyor.
Flatbed UV printers use a vacuum table for flat materials like acrylic or metal.
Rotary printers (also known as cylindrical printers) use a cylindrical fixture to rotate curved items, while conveyor-style printers use a moving belt for continuous, high-volume production.
Each setup keeps products stable and aligned for sharp, consistent results across different shapes and materials.
UV printing is ideal for promotional items because it delivers high-resolution graphics, consistent color, and scratch-resistant finishes. The instant curing process also reduces production time, making it efficient for short runs, personalization, or just-in-time manufacturing.
Yes. When combined with rotary or high-gap printing techniques, UV printing can be applied to cylindrical or slightly irregular objects (like drinkware). Specialized fixtures and rotary attachments help maintain alignment and curing uniformity.
Rotary Printing
Rotary printing involves rotating the part during printing so that artwork wraps around the circumference without distortion. It’s commonly used for bottles, jars, and cylindrical promotional products to achieve 360° designs.
Rotary printing works best with round or slightly tapered objects made of plastic, metal, or glass. Examples include water bottles, jars, tumblers, and tubes. Proper fixturing ensures the item rotates evenly for precise graphics.
Pad and screen printing traditionally offer limited coverage and may require multiple print passes. Rotary UV printing provides full wrap-around designs in a single pass, greater color fidelity, and better resolution without the need for separate plates or extended drying times.
Bottle Printing
To print on bottles, use a rotary UV printer with a cylindrical fixture that turns the bottle as it prints. After loading your design, mount and align the bottle, then print with UV-curable inks that harden instantly.
This process delivers seamless, high-resolution prints on glass, plastic, or metal bottles — waterproof, durable, and ready for production.
IDS printers like the RevPro 360 and Prisma ZMax PRO are built for precise, high-speed bottle printing.
