How I Evaluate Flexo Press Vendors (A 5-Step Checklist for Admin Buyers)

If you're like me—an office administrator tasked with sourcing a flexo press or its parts for your label-making team—you know the drill: too many options, too little time, and everyone from the production manager to finance has an opinion.

I manage purchasing for a mid-sized packaging company. When I took over in 2021, I knew nothing about flexographic printing. I learned the hard way—chasing the lowest quote, only to discover that "cheap" doesn't mean "cost-effective." So I built this checklist. It's saved me from at least two expensive mistakes.

Here's how I evaluate a press or press parts vendor in 5 steps. This was accurate as of late 2024—the market changes fast, so verify current specs and pricing before you commit.

Who This Checklist Is For

This is for admin buyers or ops people who need to evaluate a new press line or a press parts supplier. You'll need to coordinate with your production lead. This list doesn't cover financing or leasing—just the nuts-and-bolts evaluation.

Step 1: Match the Machine to Your Real Production Needs

Don't start by looking at brochures. Start by asking your production team for a list of their top 5 most common jobs: substrate type, run lengths, number of colors, typical set-up time.

It's tempting to think the biggest machine with the most features is the best. But here's the thing—if you mostly run short labels on 5-color jobs, a massive 10-color press is wasted floor space and operator complexity. You're paying for capacity you don't use.

For example, when we evaluated the Mark Andy Pro Series, I asked our press operator: "If you ran our top 50 jobs on this, how many would fit within its spec?" The answer was all but two—and those two were jobs we already sent to a trade shop. That's when I knew it was the right scale for us.

Checkpoint: Can this machine handle 90% of your volume without significant over-capacity or under-capacity?

Step 2: Investigate the UV Curing System—A Common Oversight

Most buyers focus on the print deck and web width. They forget the UV curing system until it's too late. I've seen it happen: a buyer picks a press they love, then discovers the UV system can't cure their preferred inks at production speed.

The Mercury UV Curing System from Mark Andy is one example of an integrated system that's designed to match the press speed. But the principle is universal: ask for the curing spec before you sign.

Look for:

• Peak irradiance (watts/cm²) at full press speed
• Curing width that matches your web width
• Compatibility with your ink chemistries (especially if you use low-migration inks for food packaging)

On a related note—people think expensive vendors just charge more for the same thing. Actually, vendors who invest in matched systems (press + UV curing) deliver better reliability. The causation runs the other way: they can charge more because their rejection rates are lower.

Checkpoint: Does the UV system match the press speed for your target substrates and inks?

Step 3: Audit the Parts and Service Pipeline

Here's something I wish I'd known earlier: a press is only as good as the parts supply behind it. You can have the best machine in the world, but if a critical part has a 6-week lead time, you'll be down for weeks.

When I evaluated our first Mark Andy, I asked for a list of the top 10 most common consumable parts—anilox rolls, doctor blades, plate cylinders—and their typical lead times. Then I asked for the same for the 5 most common repair parts.

What I found: the vendor had moved to a same-day shipping model for 80% of common parts. That was a decision-maker for me, because downtime kills profitability faster than the machine price ever could.

Looking back, I should have also verified the lead times on custom parts (like rare anilox specs). I didn't. Luckily, it hasn't been a problem—but it's a gap in my process. If I could redo that evaluation, I'd check lead times on custom and common parts separately.

Checkpoint: What is the vendor's fill rate and lead time for top 10 consumable and 5 top repair parts?

Step 4: Get Real Data on Setup Time and Waste

Every vendor claims their press has fast changeovers and low waste. But claims aren't data. I ask for a documented test: a demonstration where the vendor runs two different jobs back-to-back, with a full changeover—inks, plates, die—and I time it.

Here's a mistake I made early on: I only looked at print speed (feet per minute). I didn't consider that setup time can double your effective cost for short runs. For an average job of 2,000 linear feet, a 15-minute setup vs. a 30-minute setup makes a huge difference.

Industry standard color tolerance is Delta E < 2 for brand-critical colors; Delta E of 2-4 is noticeable to trained observers. Ask for color consistency across the start, middle, and end of the run.

Checkpoint: Can the vendor demonstrate a job-to-job changeover under 20 minutes with Delta E < 2 for the first acceptable print?

Step 5: Evaluate the Vendor Relationship, Not Just the Price

This is the step most checklists skip. I've learned that a vendor who's easy to work with is worth 5-10% more in price. Here's why:

• When you need technical support at 5 PM on a Friday, who picks up the phone?
• When a part is on backorder, do they proactively suggest alternatives?
• When your operator needs training, do they have a structured program, or is it just a manual?

Our Mark Andy relationship has been good on all three fronts. I can't say that about every vendor I've worked with. The one who couldn't provide proper invoicing cost us $2,400 in rejected expenses—finance wouldn't approve a handwritten receipt. Now I verify invoicing capability before placing any order, no matter how good the deal.

I also ask: "Who else in my industry uses this vendor's equipment for similar applications?" References matter. Don't just call the happy ones—call the one who switched away, if you can find them.

Checkpoint: Do I trust this vendor to support us during a crisis? (Yes/No. No equivocation.)

Common Mistakes I've Made (So You Don't Have To)

Mistake 1: Falling for the lowest price

The cheapest press often has the most expensive total cost of ownership. Higher parts costs, longer downtime, slower speeds. One vendor who gave me a bargain price had a parts markup of 40% above the industry average. Not a bargain.

Mistake 2: Ignoring training needs

An operator who's run a different brand for 15 years needs time to adapt to a new press—even if it's "similar." Budget for at least a week of onsite training and document who's responsible for travel costs.

Mistake 3: Not validating the UV curing system early

I circled back to this because it's that common. A leading press brand nearly lost our business because they couldn't confirm UV compatibility with our inks until after the contract was signed. We walked away. The Mark Andy Mercury system was one of the reasons we stayed.

Final Note

This checklist has worked for me through 5 vendor evaluations and 2 equipment purchases. But every company is different—adapt these steps to your specific substrates, run lengths, and support requirements.

And one more thing: trust the fundamentals. A good press is one that gives stable color at high speed with minimal waste. Everything else—brand, color, marketing—is decoration on a solid base. Don't let flashy specs distract you from the machine that your operators will use daily for the next 10 years.

Pricing reference: As of early 2025, a mid-range 10-inch flexo press like the Mark Andy Pro Series runs approximately $350,000–$550,000 depending on configuration (deck count, UV system, options). Setup and installation typically adds $20,000–$40,000. Always get a current quote—prices change with raw material costs.
