Investment and Running Costs

For many small and medium-sized businesses, the total cost of ownership is just as important as the initial purchase price.

The Spectra U1 starts at $4,999, while the Spectra U1 Pro is available from $5,499. In comparison, the Mimaki UJF-3042MkII typically starts at $16,490, before factoring in installation, consumables, maintenance, and optional accessories.

Consumable costs can also have a significant impact on profitability over time. OMTech UV inks average approximately $66.7 per kilogram, while comparable Mimaki inks generally range from $131 to more than $300 per kilogram, depending on the application and formulation.

For businesses focused on maximizing margins and achieving a faster return on investment, lower operating costs can make a substantial difference over the life of the machine.

Workspace Requirements and Print Capacity

Both Spectra models offer a larger print area than the Mimaki platform, providing 350 × 450 mm of usable workspace compared with 300 × 420 mm.

The additional print area allows operators to print larger items or fit more products into a single production run, improving efficiency and reducing handling time.

The Spectra Series is also designed with compact workshops and small production spaces in mind. Its lighter footprint makes it suitable for:

Home-based businesses
Retail production areas
Small sign shops
Customisation studios
Growing eCommerce operations

The Mimaki system, while highly capable, is considerably heavier and generally better suited to dedicated production facilities with sufficient floor space and infrastructure.

Print Quality and Productivity

All three machines deliver professional-quality UV printing suitable for commercial production.

The Mimaki offers a slight speed advantage, reaching approximately 2.5 m²/h, while the Spectra Series achieves 2.39 m²/h. In day-to-day production environments, this difference is relatively minor for most small-business applications.

Where Mimaki stands out is in ultra-high-resolution work, offering up to 1200 × 1200 DPI, making it particularly suitable for applications involving:

Fine industrial labelling
Electronics marking
Detailed micro-text
Technical identification components

The Spectra Series delivers 720 × 1440 DPI, providing excellent results for:

Signage
Promotional products
Personalised gifts
Branding applications
Home décor
Custom merchandise

For most customer-facing products, print quality differences are difficult to distinguish without close inspection.

Automation and Maintenance

One of the key advantages of the Spectra Series is its focus on automated maintenance.

Both the Spectra U1 and U1 Pro include:

Automatic printhead cleaning
Automatic moisturizing functions
Continuous white ink circulation
White ink stirring systems

These features help minimize clogging, maintain print quality, and reduce downtime, particularly for businesses that may not operate their printer continuously every day.

The Spectra U1 Pro adds a dual-printhead configuration and varnish capability, enabling premium finishes such as:

Spot gloss effects
Raised textures
Layered graphics
Luxury packaging enhancements

This expanded functionality is achieved while retaining the same automated maintenance systems.

Ease of Use

Ease of operation can significantly affect productivity, especially for businesses without dedicated print technicians.

The Spectra Series features an intuitive touchscreen interface and supports both OMTech software and selected third-party RIP workflows, helping reduce training time and simplify daily operation.

The Mimaki platform relies on its proprietary software ecosystem and traditional control panel interface, which may be familiar to experienced operators but can involve a steeper learning curve for first-time UV printing users.

Speciality Printing Capabilities

The Mimaki UJF-3042MkII offers an advanced ink architecture that includes white, varnish, and primer channels, making it well suited to applications requiring specialised adhesion and industrial-grade surface preparation.

These capabilities are often beneficial for sectors such as:

Automotive components
Electronics manufacturing
Industrial product marking
Coated and specialised substrates

The Spectra U1 is designed around a streamlined CMYK + White configuration that covers the vast majority of commercial printing applications.

For businesses seeking premium decorative effects, the Spectra U1 Pro adds varnish functionality, enabling textured prints and high-impact finishes without significantly increasing operational complexity.
