It’s Not (Just) About the Printer! What Our 100th Single-Pass Inkjet System Really Taught Us

It’s Not (Just) About the Printer! What Our 100th Single-Pass Inkjet System Really Taught Us
By Ken Stack, Executive Chairman, Engineered Printing Solutions (EPS)

At FuturePrint Industrial Print in Munich, we marked a milestone that took EPS four decades to reach: our 100th single-pass inkjet production system printing direct-to-object in live manufacturing. Add that to more than 300 multi-pass DTO inkjet systems and over 2,000 pad printers, and the number tops 2,400 installations worldwide. The congratulations were nice. But what I kept thinking about was everything we had to learn, and unlearn, to get here.

The headline isn’t “100 printers.” It’s “100 production systems.” That distinction between a print engine and a complete, end-to-end automated decoration solution, is where the real story of industrial inkjet lives. It’s also where too much of our industry still gets it wrong.

The Printer Was Never the Product. The Manufacturing Production System Is

For years, our industry talked about printheads, resolution, and ink chemistry as if a printer sitting on the factory floor could deliver ROI by itself. It can’t. The print step is only part of a manufacturing process that must also load and orient parts reliably, prepare surfaces for adhesion, inspect quality inline and offload finished goods without bottlenecks. When any one of those links is manual or inconsistent, the economics degrade fast. Our early digital projects taught us this the hard way: a great print engine inside a weak workflow still produces a weak business case.

Inkjet Technology Is Enabling the DTO Production Market

Pad, screen, and offset printing are extraordinary technologies. For long, stable runs they remain incredibly efficient. EPS built its first two thousand systems on analog for good reason. But manufacturers now manage proliferating SKUs, shorter runs, regional and seasonal variants, and growing demands for variable data—serialization, traceability, and regulatory coding—at production speed. In that environment, the make-ready and tooling overhead of analog becomes a drag on agility, not a driver of throughput. Digital DTO didn’t win because analog got worse; it won because the market changed.

The Real ROI Is Labor Automation

Eliminating plates and tooling costs matters. Our white paper, “The Shift in Direct-to-Object Printing,” lays out the break-even economics in detail and the math is compelling. A seven-color pad printing job carries roughly $500 in setup costs per run. A three-color job runs about $300. Digital’s cost-per-part is essentially flat regardless of run length. For runs under 5,000 to 7,000 units, digital wins on pure tooling economics alone.

But that’s small potatoes. The transformation shows up on the labor line when you automate the entire cell—feeding, pretreatment, single-pass print, inline vision, and offload. Consider a real deployment in hard-hat decoration from one of our customers. A typical three logo job averaged only 20 units. Analog required nine plates, nine ink mixes, and nearly five hours of labor. After moving to a fully automated single-pass UV inkjet cell, labor dropped by 81%, from 289 minutes to under 55 minutes, delivering about $285 in labor savings per job. At six jobs per day, annual savings topped $400,000 with payback in under 18 months. That is a labor automation and production efficiency story, not just a tooling story.

Engineering Printing for Adhesion, Color, and Consistency on 3D Parts

Printing onto three-dimensional objects is not paper. UV-cured inks rely on mechanical adhesion, which depends on the surface energy of each substrate. If pretreatment, flame, corona, plasma, or pyrosil is not validated for the exact material, parts can pass day-one inspection and fail in the field. More digital DTO projects have been derailed by adhesion than by anything related to “print quality.” Add the complexity of color management across polypropylene, glass, aluminum, and ABS, and it becomes clear why application know-how, pretreatment recipes, dot gain control on curves, geometry-aware fixturing and motion, is the real moat. These are lessons earned across deployments, not components you can buy off the shelf.

Direct-to-object approaches also remove labels and secondary decoration steps, cutting waste, simplifying supply chains, and enabling inline decoration within manufacturing, a sustainability and efficiency win many factories now prioritize.

What DTO Means for Manufacturers in North America, Europe, APAC and Globally

Across the U.S., the operators who could set up complex multicolor analog jobs by feel are retiring, while the incoming workforce expects software-driven, computer-like equipment. The fastest path to resiliency is a single-pass, automated decoration cell that runs with fewer hands and less variability shift-to-shift. When inline pretreatment, print, and vision inspection are engineered together, you stabilize quality, compress training time, and make ROI less dependent on employee knowledge, exactly what North American plants need as they scale personalization, traceability, and shorter runs.

In Europe, brands manage a high mix of regional languages, compliance marks, and seasonal SKUs. Direct-to-object printing removes labels and secondary steps, decreasing material waste while enabling just-in-time decoration inline with assembly. Our 100th single-pass milestone, announced in Munich, underscored a broader EU trend: digital DTO earns its keep when it’s delivered as a complete production system with validated pretreatment, geometry-aware handling, and closed-loop inspection, not as a standalone print engine.

APAC manufacturers often prioritize scalability and replication across multiple sites. Standardized, application-specific automated decoration cells—where feeding, pretreatment, print, and QA are pre-engineered as one—allow factories to copy-paste capacity with predictable uptime and quality. The question isn’t “which printhead?” but “how many decorated parts per hour, how many operators per shift, and what’s my cost per part?” When those answers are guaranteed at the cell level, expansion becomes a planning exercise rather than a custom engineering project.

From Custom Printers to Standardized, Vertical‑Specific Production Cells

For decades, capital equipment was sold as a machine that showed up on a truck and got bolted to the floor. The customer figured out the rest. That model breaks down in digital DTO. The next generation will be delivered as integrated decoration cells configured for the substrates, throughput, and quality targets of a given vertical. From packaging (caps, closures, rigid containers) and medical to industrial components and promotional products, manufacturers can buy guaranteed decorative parts per hour at a known labor cost. In this model, the system integrator who owns automation, application knowledge, and service becomes more important than any individual component vendor.

What Next in DTO

Our first 100 single-pass systems at EPS taught us that application knowledge, pretreatment, geometry handling, vision, color on 3D parts is the differentiator, and automation is the ROI engine. The next 100 will be about repeatable, pre-validated cells that can drop into production with minimal commissioning, accelerate payback, and be scalable across sites. We are clear that manufacturers were never really buying printers. They were buying a known volume and quality of decorated parts per hour with as few people in the loop as possible. For us, the companies that deliver the full production solution, not just a printer, will own the next decade of this DTO production market.
