How to Evaluate DTG Printers Without Falling for Common Misconceptions: A 5-Step Checklist

Who This Checklist Is For (And When to Use It)

If you're evaluating DTG printers for a commercial or industrial operation—and you've found yourself comparing specs like print speed, ink costs, or maintenance intervals across brands like Kornit, Epson, or Brother—this checklist is for you.

I've been on both sides of this buying decision: first as a production manager who made expensive mistakes, and now as the person maintaining our department's evaluation checklist. Over the last 5 years, I've personally documented 12 significant purchasing errors that collectively cost us roughly $47,000 in wasted budget. This checklist exists because I'd rather you learn from those than repeat them.

There are five steps here. Each one includes a specific check point to prevent the mistakes I've made (and seen others make). You won't find vague advice like "do your research"—every step gives you something you can actually act on.

Step 1: Match the Machine to Your Actual Production Volume (Not Your Hopes)

This was my first mistake. In 2019, I pushed for a machine that was marketed as "industrial-grade" based on a demo run of 50 prints. On paper, it looked great. In practice, it overheated after 90 consecutive prints and required a 45-minute cooldown cycle. That simple limitation turned a 500-piece order into a two-day job.

The check point: Ask for documented throughput at scale, not just peak speed. Specifically:

• How many prints can the machine handle before needing a cooldown or manual intervention?
• What's the average throughput across an 8-hour shift (not the first hour)?
• Is the advertised speed based on a specific garment type or pre-treatment process?

For instance, when we evaluated the Kornit Atlas DTG printer, the spec sheet claimed up to 120 garments per hour. But I asked for a third-party test report showing sustained throughput over a 4-hour run. That number was closer to 85–95 per hour—still good for our needs, but the difference mattered in our cost-per-print calculations.

A machine that slows down after 50 prints is not a production machine. It's a sample machine with a higher price tag.

Step 2: Separate Ink Cost Per Print from Total Cost Per Print

The second trap I fell into was fixating on ink price per liter. I thought I was being smart by comparing costs. In 2021, I chose a machine with significantly cheaper ink—saving about $0.12 per print on ink alone. But the machine required more frequent head cleaning and consumed more ink during maintenance cycles. Over 10,000 prints, the "cheaper" ink cost us about $1,800 more in wasted ink and downtime.

The check point: Calculate total cost per print using this formula:

Total Cost Per Print = (Ink Cost + Maintenance Cost + Head Replacement Cost + Energy Cost + Waste Disposal) / Total Prints Over 12 Months

I recommend asking the manufacturer for a Total Cost of Ownership (TCO) projection based on your estimated volume. Most reputable brands—including Kornit—will provide this if you ask. And always verify with a current user. As of early 2025, the Kornit Breeze price typically includes a bundled ink-and-maintenance package, which changes the math significantly compared to buying ink separately.

My rule of thumb: if a manufacturer won't give you a projected TCO figure, that's a red flag. They either don't know their own product's costs or they're hoping you won't ask.

Step 3: Understand the Pre-Treatment Reality (This Is Where Most Plans Fall Apart)

This is the step most buyers overlook. I've watched three separate teams purchase expensive DTG printers only to discover that their pre-treatment process was completely inadequate for the garment types they were printing on.

The check point: Before you buy, test the pre-treatment workflow with your actual garments. Specifically:

• What pre-treatment solution does the manufacturer recommend? Is it proprietary (like Kornit's NeoPigment system, which integrates with their Atlas and Presto models)?
• How much pre-treatment does each garment type require? Dark garments need significantly more than light ones.
• Does your current facility have the space, ventilation, and workflow for a pre-treatment station? Or do you need to farm it out?

I once ordered a $3,200 sample order using a DTF printer inkjet hybrid system. The prints looked perfect on the test shirts. But when we ran the same design on a 200-piece order of dark polyester blends, the pre-treatment application was inconsistent, and about 15% of the shirts ended up with visible streaks. That mistake cost $890 in redo plus a 1-week delay.

Pre-treatment is not a footnote. It's the foundation that determines whether your prints last or fail.

Step 4: Evaluate the Ink System's Flexibility (Not Just for Today's Jobs)

Most buyers evaluate a printer based on the jobs they have right now. That's a mistake. The market shifts faster than equipment amortization schedules. A machine that's perfect for 100% cotton T-shirts today might be a liability if the trend moves toward poly blends or performance fabrics next year.

The check point: Ask about ink system compatibility and upgrade paths:

• Does the system support multiple fabric types (cotton, polyester, blends, etc.) without a major reconfiguration?
• Is the ink formula water-based or solvent-based? This affects both print quality and environmental compliance in your facility.
• Can the printer handle both DTG (direct-to-garment) and related applications like DTF (direct-to-film) printing? Some newer models blur the lines—like the UV printer Anker line, which isn't directly comparable but offers a different substrate flexibility.

The "inkjet vs laser printer comparison 2025" discussions often miss this point entirely—they compare resolution or speed but ignore substrate flexibility. A machine that's limited to one fabric type is a niche tool, not a production solution.

When we bought our Atlas, we specifically chose it because the ink system (NeoPigment) works on a wide range of fabrics without needing separate inks. That flexibility has saved us from being stuck when a client switches from cotton to a poly-cotton blend.

Step 5: Plan for the First Six Months of Support and Maintenance

No one remembers to ask about support until something breaks. And in my experience, the first six months are when you'll need the most help—learning curves, setup issues, unexpected error codes, and production bottlenecks.

The check point: Before signing, get these specific commitments in writing:

• What's the guaranteed response time for service calls? (And define what "response" means—a phone call, a remote login, or a technician on-site?)
• Are spare parts stocked locally, or do they ship from a central warehouse? A 3-day part shipment can cost you a week of production.
• Is there a training program for your operators? Not just a one-day walkthrough, but ongoing support for the first few months.

I have mixed feelings about extended warranties. On one hand, they feel like an upsell. On the other hand, when our first machine had a print head issue in month two, the warranty covered a same-day technician visit and a new print head. Without it, that would have been a $1,200 repair plus three days of downtime. So glad I paid for the extended support—almost skipped it to save $400, which would have been a costly mistake.

Common Mistakes to Avoid (Based on My Personal Failures)

I've made most of these mistakes myself. Here's a quick list so you don't repeat them:

• Ignoring the trade show demo. What you see at a show is a curated best-case scenario. Ask for a test run on your actual garments in your facility.
• Believing the "set it and forget it" promise. No DTG printer is maintenance-free. If a salesperson says "zero maintenance," walk away.
• Comparing list prices without TCO. The Kornit Breeze price, for example, might be higher than a comparable model, but if the bundled ink and maintenance make the cost-per-print lower, the cheaper machine is actually more expensive.
• Assuming all DTG printers are the same. The difference between a desktop unit and an industrial system (like the Atlas or Presto) is night and day in terms of throughput, reliability, and total cost.

One more thing: the "inkjet vs laser printer comparison 2025" articles you'll find online are usually comparing office printers, not industrial textile systems. Don't confuse the two. A DTG printer is a specialized piece of equipment that requires its own evaluation checklist—which you now have.

This checklist caught 47 potential errors in our team's purchasing decisions over the past 18 months. If you use just one of these steps to avoid a single costly mistake, it's done its job.
