I Almost Bought the Wrong Flexo Press: A Mark Andy Pro Series Cost Lesson in UV Drying, Paper Sizes, and Total Ownership

The Call That Made Me Question My $800,000 Decision

Last November, a regular customer called about a label run we'd just shipped. "The blue is off," he said. "It's not the blue we approved." I pulled up the proof on my screen. It looked fine. Then I held the physical sample next to their Pantone chip. Delta E was something like 4.8. That's noticeable to anyone, not just a trained eye.

Honestly, that call stung. Because it wasn't a new problem. It was the result of a decision I had made six months earlier—the day I signed off on a new flexographic press.

The Background: Why We Bought a Mark Andy Pro Series

I run a small label shop. We handle short to medium runs for food and beverage clients. For years, we used an old 8-station flexo press that had seen better days. My team was constantly fighting registration issues, and our makeready times were killing us. So when we finally got approval for a capital investment, I threw myself into research.

Here are the options I looked at: a refurbished press from a local dealer that was about 40% cheaper, and a brand-new Mark Andy Pro Series flexo press with an integrated Mercury UV curing system. The numbers said the refurbished press made sense—lower upfront cost, familiar technology, and we could pay cash. But something felt off. I'd read enough about the Pro Series to know that its servo-driven platforms and repeatable registration would save us money over time.

So we went with the Mark Andy. The price was painful. But in my head, I thought: "This is the safe choice. It's a premium brand. It can't fail." That's where my mistake started.

The Process: What They Didn't Tell Me About the UV Ink Drying System

Installation went smoothly. The machine ran beautiful test prints at 300 feet per minute. My operators loved the touchscreen controls. For the first two weeks, everything looked perfect—I even started feeling smug about the decision.

Then came a 12,000-piece order for a beverage company. The job required a high-opacity white ink plus a clear varnish, printed on a 2.2-mil BOPP film. We'd printed similar jobs on our old press with solvent inks, so I didn't think twice about the substrate. But here's the thing: the Mark Andy came with the Mercury UV system, and UV inks behave completely differently from solvent inks. The drying speed depends on the photoinitiators in the ink, the UV energy output, and how well that energy is matched to the ink's absorption spectrum.

We'd specified a generic UV ink from our regular supplier. Nobody asked whether it was formulated for the Mercury system. The ink looked fine when we pulled small samples. But at production speed, the white ink wasn't fully curing under the lamp. The result? The layers didn't bond properly, and when we rewound the roll, the ink smeared. We caught it after about 4,000 feet had printed. That's $2,800 of film and ink, plus 30 hours of press time, headed for the trash.

Why didn't I notice earlier? Because the test prints we made were only a few hundred feet, and we ran them at half speed. At 150 feet per minute, the UV dose was more than enough. At 300 feet per minute, the exposure time was halved. My gut told me something was off during the run, but the press performance data looked good. I ignored the gut feeling.

It took three weeks and a visit from the ink supplier to sort out the chemistry. We finally learned that the ink needed a higher concentration of certain photoinitiators, or we needed an additional UV lamp along the curing station. Mark Andy's Mercury system had adjustable output, but I'd never touched the settings. The technician showed us how to measure UV energy with a radiometer, and we found that our actual peak irradiance was below the recommended 200 mW/cm² for that ink film. After adjusting the lamp power and slowing that particular station slightly, we got a full cure. But the damage was done—both to our budget and to my confidence.

It took me four months and three bad jobs to understand that the Mark Andy flexographic UV ink drying system is a complete subsystem, not an afterthought. It has to be tuned for your inks, your substrates, and your line speed. Skipping that tuning step is like buying a sports car and never leaving the garage.

The Turn: Looking Back, I Should Have Asked Better Questions

Looking back, I should have insisted on a full production-speed trial with the exact ink and substrate we planned to run. At the time, the sales engineer offered a two-day training session, but we were in a busy stretch. So we skipped it. That decision cost us roughly $8,000 in wasted materials and rework, plus a delayed delivery that made the customer seriously angry. If I could redo that decision, I'd invest in better specifications upfront. But given what I knew then—nothing about the vendor's interpretation quirks—my choice was reasonable.

But that's not all. During the same period, I was getting questions from customers about alternative printing methods. One potential client asked about DTF versus UV printer for a short-run label project. Another asked if we could 3D print prototype labels on a Creality Ender 3 V3 SE 3D printer, which he had just bought for his own tinkering. These questions forced me to think about what our press actually brings to the table.

For short runs—say, under 500 pieces—a UV flatbed or DTF transfer process can absolutely be a better choice. No plates, no cylinder changes, no makeready. But those technologies struggle with repeatable color accuracy and maximum print speed at medium to high volumes. And a 3D printer, like the Creality Ender 3 V3 SE, is a prototyping tool, not a production device. It can't reliably reproduce Pantone colors on film, and its throughput is nowhere near what a flexo press can handle.

When I walk customers through these trade-offs, I realize how many of them assume that "printer" means "whatever device sits on a desk." That's why customer education matters. If I don't explain why our production press is different, they'll keep asking why we're more expensive than their friend's UV printer. An informed customer asks better questions and makes faster decisions—that's been my experience, anyway.

The Result: What I Learned About Total Cost of Ownership

Fast forward to today. Our Mark Andy Pro Series is now producing consistently at 300 feet per minute, with Delta E values under 2 on most jobs. We've implemented a pre-flight checklist that includes: UV energy verification, ink-substrate compatibility test, and a full-speed trial before any new job combination. In the past 18 months, we've caught 47 potential errors using that checklist. That doesn't make up for the initial embarrassment, but it has saved us a lot of money.

Here's my honest takeaway: the cost of a Mark Andy Pro Series flexo press is not just the purchase price. It's the UV curing system setup, the training hours for your crew, the calibration tools, the wasted material when something goes wrong. When people search for "Mark Andy Pro Series flexo press price cost," they usually want a number. I can't give you one because it depends on configuration, options, and your application. But I can tell you this: the cheapest configuration isn't always the least expensive.

Same with printer paper size. We print labels on a lot of different substrates, from 2×2 inch die-cut labels to full 13×19 inch sheets. The industry standard for paper size matters because your press's maximum web width and repeat length determine what jobs you can take. For example, Mark Andy offers different web widths; if your customers need 16-inch wide labels, you need the right model. I once assumed all Pro Series presses were the same. They're not.

The Replay: What I'd Do Differently

If I could redo that purchase, I'd change three things:

• Demand an on-site trial using the actual inks and substrates we'd run in production.
• Spend the money on a UV energy meter and operator training before the first full-scale run.
• Read the technical manual for the Mercury curing system cover to cover before turning on the press.

It's not about the machine being bad. It's about me treating it like a magical box that would fix everything by itself. That's no one's fault but mine.

The good news? My team now knows more about UV ink chemistry than most of our competitors. I've made it part of our onboarding. And every time I see a job go through without a hitch, I remember the $8,000 lesson that taught me to look beyond the sticker price.

Industry standards: For color-critical work, aim for Delta E < 2 (Pantone Matching System). And keep in mind that 300 DPI is the standard minimum resolution for commercial print; if you're buying from a vendor, ask for that spec.

If you're in the market for a flexo press, or if you're just trying to understand why someone would choose a Mark Andy over a digital printer, take the time to understand your real printing requirements. Know your paper sizes, your UV curing needs, your daily run lengths. Then compare technologies—DTF, UV flatbed, even 3D printing—based on those needs. An informed customer always makes a better decision. That's not a cliché, that's the result of a very expensive mistake.
