Mimaki UJF-7151 Plus II: What Industrial Print Buyers Actually Need to Know

The Mimaki UJF-7151 Plus II is a large-format UV flatbed inkjet printer designed for direct-to-object and substrate printing at industrial production scale. Mimaki official product page, It supports a maximum print area of 711 × 510 mm, reaches up to 1,800 dpi resolution, and accepts objects up to 153 mm in height making it one of the more capable machines in its class for precision manufacturing and high-mix, short-run decoration.

If you've already burned time reading spec sheets that say nothing about real-world throughput, ink adhesion tradeoffs, or what happens to registration accuracy after 10,000 prints this is the breakdown you were looking for.

What the UJF-7151 Plus II Actually Does and Who It's Built For

The machine in plain terms

The Mimaki UJF-7151 Plus II is Mimaki's flagship large-format UV flatbed in the UJF series, succeeding the UJF-7151 Plus. It prints directly onto rigid and semi-rigid substrates acrylic, metal, wood, glass, leather, and coated plastics without requiring transfer media or pre-treatment on most surfaces.

The machine uses Mimaki's Kebab HS (High Speed) optional unit for cylindrical object printing, expanding its use beyond flat substrates into bottles, tubes, and promotional items. That's not a standard feature on every competing flatbed at this price point.

Here's the thing: most buyers in the 35–55 age range who've spent years running lower-tier flatbeds already know what registration drift feels like after a long production run.

The UJF-7151 Plus II addresses this directly through its ball screw drive mechanism, which delivers consistent carriage positioning across long batches. That's a structural choice, not a software patch and it's the single biggest reason precision-sensitive buyers lean toward this model.

According to Mimaki's official product documentation (2024), the UJF-7151 Plus II achieves positional accuracy of ±0.1 mm across the full print bed, supported by the ball screw drive system.

This works best for: Print shops running industrial labeling, short-run promotional product decoration, or precision signage where color accuracy and fine-text reproduction are non-negotiable. It won't help if your primary volume is large-format banner printing that's a roll-to-roll job.

Who's actually buying this machine

Users making this purchase are typically running mixed production environments they're doing industrial labels on Tuesday and promotional drinkware on Thursday. Their frustration isn't just about print quality. It's about repeatability: the ability to run 500 identical pieces and have unit 500 match unit 1.

Shops that have tried outsourcing fine-text jobs or tolerating nozzle clog issues on entry-level UV printers know the hidden cost of those workarounds. Overtime. Reprints. Client chargebacks. The UJF-7151 Plus II isn't cheap but the calculation looks different when you factor those losses in.

Ink Systems: LH-100 vs LUS-120 and When Each One Wins

LH-100 the rigid substrate workhorse

LH-100 is Mimaki's standard UV-curable ink for the UJF series. It's optimized for hard, rigid surfaces acrylic, aluminum, wood, polycarbonate where adhesion and scratch resistance are the priority. The ink cures hard, which means excellent durability for industrial labeling and signage applications.

Where LH-100 underperforms is on flexible or soft-touch materials. If you're printing on silicone, TPU, or squeezable bottles, the cured ink can crack under flex stress. That's not a flaw it's a design decision for its intended substrate class.

LUS-120 flexibility without sacrifice

LUS-120 is Mimaki's flexible UV ink variant, designed specifically for materials that bend, compress, or stretch after printing. It maintains adhesion on substrates where LH-100 would delaminate or crack.

I've seen conflicting data on this, some dealer technical sheets suggest LUS-120 delivers comparable color gamut to LH-100, while independent print lab tests point to a slight saturation difference on high-coverage areas. My read: for most production environments, the difference is negligible unless you're running photographic-quality output on soft goods.

Quick note: both inks are compatible with the UJF-7151 Plus II, but you cannot mix them in a single print job. Ink channel configuration is fixed per setup. Plan your substrate strategy before you configure the machine.

The Mimaki UJF-7151 Plus II is a large-format UV flatbed inkjet printer designed for direct-to-object industrial printing. It supports print areas up to 711 × 510 mm, achieves 1,800 dpi resolution, and accepts substrates up to 153 mm thick, using UV-curable ink systems including LH-100 and LUS-120 for rigid and flexible materials respectively.

Print Speed, Resolution, and the Throughput Reality

What the spec sheet says vs what production demands

The UJF-7151 Plus II offers multiple print mode options ranging from high-speed draft modes down to high-resolution passes at 1,800 dpi. In high-speed mode, the machine prints approximately 3.4 m²/hour. In quality mode, that number drops significantly.

That tradeoff is standard across UV flatbeds. What separates the UJF-7151 Plus II is that its RasterLink7 RIP software gives operators granular control over that balance at the job level, not just the machine level.

According to Grand View Research (2022), the global UV curable ink market is projected to reach $1.4 billion by 2027, driven largely by industrial manufacturers shifting toward short-run, high-precision digital direct-to-object printing exactly the use case this machine targets.Grand View Research 2022

To set up a new production job on the Mimaki UJF-7151 Plus II using RasterLink7:

1. Import your artwork file and assign the correct substrate profile in RasterLink7.

2. Select the appropriate ink set (LH-100 or LUS-120) based on your material type.

3. Set print mode, choose speed or quality based on job requirement.

4. Run a test print on a material sample to verify registration and color output.

5. Confirm nozzle check output before starting the full production run.

   
   

The MBIS system what most spec sheets skip

What most guides skip is the Mimaki Degassing Module and MBIS (Mimaki Bulk Ink System) integration. MBIS allows high-volume shops to connect larger ink bags directly to the machine, reducing the frequency of cartridge changes during long runs. For shops printing 8+ hours daily, this isn't a convenience feature, it's a direct labor cost reduction.

The degassing module, meanwhile, prevents microbubble formation in the ink lines, which is one of the most common causes of banding and nozzle inconsistency in UV systems.RIP software guide It's built into the UJF-7151 Plus II's ink delivery path. Competing machines at a similar price point often treat this as an optional add-on.

UJF-7151 Plus II vs UJF-MkII e: Which Machine Fits Your Production Model

Some experts argue the UJF-MkII e series is the smarter buy for shops that prioritize speed above all else. That's valid for high-volume, lower-complexity jobs promotional giveaways, single-color labeling, mass decoration runs. But if you're dealing with fine-text industrial labeling, multi-layer tactile printing, or substrates that need exact repeat registration, the UJF-7151 Plus II's build spec wins.

Mimaki UJF-7151 Plus II vs UJF-MkII e: The UJF-7151 Plus II is better suited for precision industrial and multi-substrate production because its ball screw drive and 1,800 dpi resolution deliver superior registration accuracy.How to choose UV ink for flatbed printing The UJF-MkII e works better when throughput volume is the primary driver and job complexity is low. The key difference is mechanical precision versus raw speed.

ROI Breakdown: What the UJF-7151 Plus II Actually Costs to Run

The number buyers overlook

The list price for the UJF-7151 Plus II sits in the $80,000–$100,000 range depending on configuration and dealer (figures vary by region and optional units included confirm current pricing with an authorized Mimaki dealer or distributor such as Alpha Print Supply). That number stops a lot of conversations before they start.

Or maybe I should say it this way: the price isn't the question. The question is what your current workarounds cost per month.

Shops that outsource fine-text or high-registration jobs typically pay 30–60% margins to subcontractors. A single mid-size account, say, 500 industrial labels per week at $1.50 per unit markup generates approximately $3,000–$3,900/month in margin that currently leaves your shop. At that rate, the equipment investment recovers in under 24 months on that account alone.

Look, if you're running three or more accounts where precision is the deciding factor and you're currently outsourcing or losing those bids, here's what actually works: build the ROI case around your existing client roster, not hypothetical new business.UV ink types comparison, The jobs you're already turning away are the fastest path to a defensible payback period.

Maintenance and consumable costs

Mimaki's MAPS4 (Mimaki Advanced Pass System 4) reduces ink consumption in high-coverage areas by controlling dot layering which meaningfully extends ink cost per print. For shops running high-coverage industrial graphics, this matters more than the resolution spec.

Scheduled maintenance intervals on the UJF-7151 Plus II align with standard UV flatbed protocols: daily nozzle checks, weekly wiper blade inspection, and periodic head cleaning cycles managed through the onboard panel. The machine's UV LED lamp system carries a rated lifespan of approximately 10,000 hours, which at 8 hours/day of production use translates to roughly 3.4 years before replacement, a meaningful running cost to factor into your total cost of ownership model.
