Guide to Choosing Your Roland UV LED Printers

For graphic professionals, print shop owners, and industrial manufacturers, adding UV-LED printing to the production floor unlocks a highly profitable world of textures, dimensional finishes, high-opacity white ink, and direct-to-substrate versatility. However, choosing the correct physical format and ink formulation is critical to maximizing your shop’s return on investment.

Roland’s professional UV lineup features three distinct classes of machinery: the roll-to-roll TrueVIS MG Series, the large-format flatbed VersaObject CO Series, and the benchtop VersaObject MO-240. This guide breaks down their physical differences, ink configurations, and ideal business use cases to help you make an informed decision.

Form Factor and Media Handling

The first and most important decision factor is how each machine physical handles the materials you print on.

TrueVIS MG Series (MG-300 / MG-640)

This is an integrated print-and-cut device designed primarily for roll-fed flexible media under 1 mm in thickness. It handles roll-to-roll production of decals, stickers, window films, backlit graphics, and flexible packaging mockups. It features a specialized Media Vacuum Assist function to keep thin media flat during operation.

VersaObject CO Series (e.g., CO-300i / LO-640)

Roland Versa Object CO Series - Flatbed UV & Hybrid Printer — Roland Versa Object CO Series – Flatbed UV & Hybrid Printer

These are industrial, large-format direct-to-substrate printers available in flatbed configurations (with a powerful integrated vacuum bed) or belt-driven hybrid models. Flatbed models handle large, rigid boards like wood, metal, glass, and heavy signage sheets weighing up to 220 pounds (100 kg).

VersaObject MO-240

This is a dedicated benchtop flatbed direct-to-object printer with an A2-sized bed (24 inches by 18 inches maximum printing area). It features a built-in vacuum table and handles fast, varied, small-batch jobs for finished goods and three-dimensional items.

Physical Clearance and Thickness Boundaries

Because UV printing allows you to print on dimensional items, physical carriage height defines what objects can pass underneath the printheads.

TrueVIS MG Series

The TrueVIS MG series is strictly for thin substrates. The standard media limit is 1 mm. However, you can add an optional ET extension table to print on semi-rigid cardstock or folding carton paper stocks up to 1 mm thick, making it ideal for packaging prototypes.

VersaObject MO-240

Built to accommodate tall objects, the VersaObject MO-240 features an impressive 8-inch (204 mm) clearance height. This lets you place dimensional boxes, electronics casings, thick books, and blocky items directly on the print bed.

VersaObject CO Series

Offering the absolute maximum vertical clearance in the lineup, the newer VersaObject CO Series flatbed models provide up to 9.5 inches (242 mm) of clearance for tall, bulky, or highly irregular physical objects (such as pre-fabricated doors, thick panels, or tall merchandise).

Technical Specification Matrix

Ink Technologies and Specialized Applications

While all three models print beautiful, vibrant CMYK graphics, they support distinct ink formulations tailored to different mechanical demands.

MG Series Specialty Inks

Along with standard ECO-UV (EUV5) inks, the MG Series supports EUVS shrink inks. These materials have elastic, stretchable properties for printing on thin films. They can shrink and wrap around flexible packaging without cracking.

CO Series and V-BOND Support

The CO Series relies on dual CMYK or expanded ink sets (featuring Red, Orange, White, Gloss, and Primer) using ECO-UV 5 inks. Additionally, it fully supports V-BOND Ink, a highly durable, cost-effective formulation that is nickel-free and CPSIA/Toy Safety compliant. This makes it safe for use on items children handle, such as custom lunch boxes, toys, and drinkware.

MO-240 Multi-Ink Versatility

The MO-240 uses high-capacity 750 ml pouches and supports three distinct ink configurations depending on your business focus:

EUV-5 – General-purpose ink with a wide color gamut (utilizing Orange and Red inks) for general rigid and flexible substrate printing.
V-BOND – Toy-safe and skin-safe certified ink for everyday custom promotional goods.
EUV-H – Award-winning industrial-grade hard ink designed for exceptional scratch, solvent, and abrasion resistance. When paired with a dedicated primer, EUV-H provides superior adhesion on challenging rigid surfaces like metal, glass, and acrylic—even allowing printed glass objects to withstand domestic dishwashers.

Specialty Hardware Accessories

TrueVIS MG Series Accessories

Compatible with the TB-30 tension bar to stabilize ultra-thin plastic films (down to 30 microns) during print and cut runs, alongside the media take-up unit for unsupervised overnight roll-to-roll workflows.

VersaObject CO Series Accessories

Features compatibility with the Rotary Rack XL and XXL accessories. This allows you to place cylindrical items (such as insulated water bottles, glass vases, and candle sticks ranging from 0.5 to 7.75 inches in diameter) directly onto the flatbed to print full 360-degree wrapped graphics.

VersaObject MO-240 Accessories

Supports its own dedicated optional rotary printing unit for fast cylindrical object wrapping. It also fully integrates with the PrintAutoMate software expansion, which allows operators to automatically map artwork onto objects laid out in custom printing fixtures or jigs, drastically speeding up workflow.

Which Machine Fits Your Business?

Choose the TrueVIS MG Series if:

Your primary business focuses on stickers, decals, labels, and high-end window graphics. It also includes backlit signs, custom wall coverings, and packaging mockups. The integrated cutter streamlines production by eliminating the need to transfer printed sheets to a separate cutting plotter.

Choose the VersaObject CO Series if:

You are printing large-scale commercial signage, interior décor boards, exhibition panels, or heavy industrial control panels. This hybrid/flatbed format handles large sheets, rigid boards, and heavy, irregular items that need a large flatbed work area.

Choose the VersaObject MO-240 if:

Your shop handles high-mix, high-volume custom work for promotional products and industrial parts. This includes phone cases, electronics, golf balls, trophies, gauges, dials, and casings. These jobs need strong abrasion resistance, quick setup, and fast turnaround.
