Mimaki UV Printer UJF-6042: Price, Capabilities & Common Mistakes (A Practical FAQ)

Common Questions About Mimaki Printers (Answered by Someone Who's Made the Mistakes)

I'm a production manager who's been handling industrial print orders for about 6 years. I've personally made (and documented) around 12 significant mistakes in equipment selection and setup, totaling roughly $4,200 in wasted budget and materials. Now I maintain our team's checklist to prevent others from repeating my errors. Here are the answers to the questions I get asked most often—and a few you probably should be asking but aren't.

1. What's the actual price of a Mimaki UJF-6042 MkII UV printer?

If I remember correctly, the base price for a new UJF-6042 MkII is around $18,000 to $22,000 USD. (I should add: that's without the optional roll-to-roll unit, which adds a few thousand.) But here's the thing: the list price is just the starting point. People assume that's the total cost. The reality is you'll want to budget for:

• Ink starter kit: Roughly $600-800.
• Training: Often $500-1,500 depending on your setup.
• Warranty upgrade: A 2-year on-site service plan can add $1,500-2,500.

On a $2,800 order I messed up because we skimped on training. That cost $890 in redo plus a 1-week delay. In my opinion, the training budget is non-negotiable.

2. Is a Mimaki wide format printer the same as a large format printer?

Sort of. The terms are used interchangeably, but there's a nuance. Wide format typically refers to printers that handle media up to 64 inches wide (like the Mimaki JV300 series for roll-to-roll). Large format is often used for something like the UJF-6042, which prints on flat rigid sheets up to about 23.6 x 19.7 inches.

The mistake I see: people buy a flatbed UV printer thinking it can handle all their big signage work. It can't—you need a roll-to-roll or a hybrid for that. In September 2022, I watched a shop order a UJF-6042 to replace their wide-format solvent printer for banners. It was the wrong tool, and they wasted 3 weeks before realizing.

3. Why would I search for "black 3D printer filament" when looking at Mimaki?

That's a fair question. You probably shouldn't be looking for 3D filament for a Mimaki UV printer. Mimaki makes UV flatbeds and DTF printers, not 3D printers. (Though they do have the 3D inkjet technology for creating textures on prints.)

The confusion comes from the term "3D printing." UV printers can create raised, textured surfaces called 3D UV printing, which uses layers of UV varnish, not filament. If you're here because you need actual FDM filament (like black PLA), you're in the wrong place. But if you want to add tactile textures to your signs or packaging—that's UV printing territory.

4. Is an Epson ColorWorks label printer a better buy for small runs than a Mimaki?

It depends entirely on your volume and what you're printing. Epson ColorWorks (like the CW-C6000) is an inkjet label printer designed for small-to-medium runs of color labels. It's relatively compact and uses pigment ink.

Mimaki makes UV DTF printers (like the UJF-6042) which can also print on labels, but it's a very different beast. Here's the breakdown from my experience:

• Epson ColorWorks: Good for short-run, full-color labels on roll media. Easier to set up. Lower upfront cost (around $3,000-6,000).
• Mimaki UV DTF: Better for high-volume, industrial use. Can print on rigid and flexible materials. Higher upfront cost ($18,000+). Lower cost per label at high volumes.

I don't have hard data on industry-wide run rate comparisons, but based on our 5 years of orders, my sense is that if you're printing under 500 labels a day, the Epson might be more practical. Over that, the Mimaki's lower ink costs and versatility make it the winner.

5. How do I connect to an Epson printer for checking proofs?

This question is a bit off-topic for a Mimaki article, but I'll answer it because it's a common workflow issue. (Should mention: I use a standard Epson 7720 for proofs in our shop.)

The typical way is via USB or network:

1. USB: Plug it in, install the driver from Epson's site. Windows usually recognizes it.
2. Network (Ethernet or Wi-Fi): Go to your printer's control panel, find the network settings, and connect to your router. Then on your PC, add a printer and search for it by IP address.

Most of the time, the issue is firewall or driver conflicts. In 2023, I spent an hour troubleshooting because an old driver from a different Epson model was conflicting—cost us a deadline.

6. What's the one mistake people make with Mimaki UV DTF printers that costs the most money?

From the outside, it looks like UV DTF printing is just a matter of loading the film and hitting print. The reality is that film tension and alignment are critical. If the film isn't perfectly aligned, you'll get mis-registered layers—resulting in wasted film and ink.

I once ordered 200 sheets of A3 DTF film with a misaligned initial setup. Checked it myself, approved it, processed it. We caught the error when the first 50 prints had a 2mm offset. $320 wasted plus an hour of setup time. The lesson: always run a test grid of 5 covers before starting a production run.

7. Can a Mimaki UV printer replace a screen printing press for t-shirts?

This was true 5 years ago when UV DTF was new and the adhesion to fabric was poor. Today, the technology has improved. You can use a UV printer to print DTF transfers (Direct-to-Film) that are then heat-pressed onto garments. It's not a direct replacement for screen printing on high-volume white tees—screen printing is still faster and cheaper per piece for plain white shirts.

But for full-color, detailed designs on dark garments, UV DTF is a game-changer. No screens, no setup fees. The 'DTF is only for beginners' thinking comes from an era when the transfers weren't durable enough. That's changed.

8. Is the Mimaki UJF-6042 worth the investment for a small sign shop?

Had 2 hours to decide before the deadline for a rush order from a new client. Normally I'd do a full ROI analysis, but there was no time. Went with a used UJF-6042 based on word-of-mouth recommendations. In hindsight, I should have spent a week comparing it to other flatbeds.

But frankly, it's been a workhorse. For a small shop doing mixed rigid materials (acrylic, PVC, wood), it's a solid choice. The UJF-6042 can handle up to 2 inches thick, which is rare for its price point. I'd argue it's worth it if you're doing more than 20 rigid jobs a month. Less than that? Maybe look at a used Roland or an entry-level UV flatbed.
