A single-pass digital printing machine reaches 45–110 m/min because the board moves under a fixed print bar in one continuous pass, instead of stopping while a scanning bar crosses it — with 24 or 32 Epson printheads covering widths from 400 mm up to 1,050 mm, and the wide-format Seiko platform extending single-color output to 1,800 mm at 70–110 m/min. Speed comes from the combination of head count, fixed-bar geometry, and board handling built for continuous flow.
Single-pass is the production engine of the Goking lineup — the G-series direct-output ONEPASS family — and it exists for one reason: plants with high-volume corrugated demand that a scanning machine cannot satisfy. In this article I will explain how single-pass output actually works, where the 45–110 m/min envelope comes from, what a true high-volume line needs around the print engine, and how to decide between single-pass and multi-pass before you buy.
In one sentence: single-pass trades scanning flexibility for continuous speed — the board never stops, the print bar never moves, and 24–32 heads lay down the full image in one pass at 45–110 m/min.
How a Single-Pass Digital Printing Machine Actually Works
The name describes the geometry. In a multi-pass machine, a print bar with a limited number of heads scans across the board, and the board advances a step between scans — the image is built up over several passes. In a single-pass machine, the print bar is fixed across the full width, and the board runs underneath it in one continuous motion. Every color of the image is laid down in that single pass, which is why the speed is measured in meters per minute rather than meters per hour.
For that to work, the machine needs enough heads to cover the full width in one sweep. That is why the single-pass configurations cluster at 24 and 32 heads for Epson: each additional head adds width coverage at the same board speed. The narrower single-pass machines print at 400 or 525 mm; the wide-format versions step up to 795 and 1,050 mm. All of them share the same direct-output principle — board in motion, bar fixed, image complete in one pass.
Where the 45–110 m/min Envelope Comes From
The speed range is not one machine — it is the single-pass family. Here is the configuration map:
| Configuration | Heads | Print width | Speed | Colors |
|---|---|---|---|---|
| Epson single-pass | 12 / 16 | 400 / 525 mm | 45–70 m/min | CMYK / CMYK + White |
| Epson single-pass, five-color | 24 / 32 | 400 / 525 mm | 45–70 m/min | CMYK + White |
| Epson single-pass, wide format | 24 / 32 | 795 / 1,050 mm | 55–80 m/min | CMYK |
| Seiko industrial (wide) | 4–18 | 400–1,800 mm | 70–110 m/min | Single color |
Taken together, the family covers 45–110 m/min, which is the single-pass envelope of the Goking platform. The Epson machines handle full-color and five-color work at 45–80 m/min depending on width; the Seiko machines extend the top end to 110 m/min for very wide single-color production. The full family is listed on our single-pass ONEPASS series page, with machine-level detail on the single-pass product page.
What a High-Volume Corrugated Line Needs Around the Print Engine
Raw print speed only matters if the rest of the line can keep up. A single-pass digital printing machine on a high-volume corrugated line is typically connected to a digital production line made up of three units: a high-speed printing unit, a slotting unit, and an automatic stacking unit. Board goes in one end, printed and slotted boxes come out the other, and nobody touches a sheet in between.
Two more elements separate a real high-volume line from a fast printer. First, five-color CMYK + White capability, so the line can run kraft jobs with a white base without stopping to swap liners. Second, ERP integration, so job files and order data flow straight from the plant's order system into the press — that is what turns 45–110 m/min of physical speed into on-time delivery. The integration capabilities are summarized on our key features page.
Single-Pass vs Multi-Pass: Choosing the Right Engine
The decision between single-pass and multi-pass is a volume decision, and we help customers make it with three questions:
- How long are your runs? — if most jobs run long and repeat, single-pass earns its speed; if jobs change constantly, multi-pass flexibility wins
- How much changeover time can you afford? — the one-minute changeover applies across the range, but a scanning machine is built to change jobs all day, while a single-pass machine is built to keep one job flowing
- Is the line linked? — single-pass pays off most when the print unit feeds slotting and stacking units in a continuous digital line
For a growing plant that is genuinely split between the two profiles, the 2-in-1 family runs both modes on one machine — multi-pass at 700–1,500 m/h and single-pass at 45–110 m/min. For a plant whose identity is high-volume corrugated, the dedicated single-pass machine is the cleaner answer.
From Our Experience: The Retail Contract That Needed a Single-Pass Line
We commissioned a wide-format single-pass machine at a corrugated plant whose story is typical of the segment. They had won a retail chain contract that required a steady stream of identical boxes — not complicated artwork, just reliable volume delivered week after week. Their existing scanning machine could produce the work, but the throughput capped what they could promise, and the line was idle during changeovers that a continuous line would not need.
The single-pass line changed the structure of their week: the retail contract runs continuously on the single-pass engine, while their short-run custom work stays on the multi-pass machine. Two machines, two roles, no compromise — which is exactly how we advise plants to think about the two engines. The single-pass machine is not a faster multi-pass; it is a different production tool for a different part of the order book.
Two operational details about a single-pass digital printing machine rarely make it into the spec sheet, and both matter on the floor. First, the Seiko wide-format machines run 400–1,800 mm in a single color at 70–110 m/min — that is the tool for large-format single-color work and wide boards that a five-color line would waste heads on. Plants that run both Epson five-color and Seiko single-color lines usually split jobs by ink coverage rather than by width. Second, the one-minute changeover applies on single-pass lines too, but the rhythm is different: the machine is built to keep one job flowing, so the changeover matters most at shift start and between the few large switches a day — the value is in continuous uptime, not in frequent switching. We also see customers use the line connection to verify output: because the single-pass machine links to slotting and stacking units and to ERP, the order data and the finished boxes are reconciled automatically, which removes the manual counting and logging that used to eat into a high-volume shift.
FAQ — Single-Pass Digital Printing Questions
When does a single-pass digital printing machine make sense?
When your volume is high and runs are long — contract work, steady repeat orders, and linked production lines. It is a throughput decision, not a capability decision.
Can single-pass machines print white ink?
Yes — the five-color single-pass configurations print CMYK plus white, which keeps brand colors vivid on brown kraft at full line speed.
What board types run through a single-pass line?
A, B, C, and E flute corrugated, honeycomb paperboard, kraft, and coated paper — the same board range as the rest of the Goking lineup.
Does single-pass still give one-minute changeover?
Yes — the changeover applies across the range. Single-pass simply adds the continuous-flow speed that high-volume work needs between those changeovers.
Final Word: Speed Is a System, Not a Specification
A single-pass digital printing machine reaches 45–110 m/min because the whole system is built for continuous flow: fixed print bar, 24–32 heads across the width, board handling that never stops, and finishing units that keep pace on the other end. When that system is matched to the right order book — long runs, steady volume, linked line — it is the fastest way to turn corrugated board into finished printed boxes. When it is matched to the wrong one, the flexibility you gave up will cost more than the speed you gained. The engine choice should always follow the volume, never the other way around.
If your order book is telling you it is time for single-pass, the practical next step is a line simulation: share your run lengths, widths, and board types, and we will lay out the machine configuration and line integration around your real volume.
