How Fast Is a High-Speed CE Certified Machine Using UV Ink? A Throughput Guide for Corrugated Converters
Speed & Productivity
For corrugated packaging converters, the decision to invest in a high-speed ce certified machine using uv ink is often driven by a single operational metric: how many square metres of printed board can exit the line per shift. In an industry where order backlogs grow during peak seasons and where retail customers compress lead times, throughput is the denominator that determines whether a digital printer generates profit or occupies floor space. Understanding the speed architecture — single-pass versus multi-pass, linear metres per minute versus metres per hour, and the relationship between speed, print width, and job changeover time — is essential for making an informed equipment decision.
Goking's digital corrugated printer range spans multiple speed tiers, from multi-pass machines delivering 500–1,500 m/h up to single-pass printers running at 45–110 m/min. The difference between these numbers is not merely a specification sheet comparison — it reflects fundamentally different print engine architectures, each suited to different production volume profiles and application types. This article examines how each speed tier works, what limits throughput in real production environments, and how CE certification ensures that high-speed operation does not compromise operator safety or print consistency.
Why Production Speed Is the Defining Metric for a High-Speed CE Certified Machine Using UV Ink
A high-speed ce certified machine using uv ink addresses the most persistent bottleneck in corrugated digital printing: the trade-off between quality and throughput. In conventional flexographic production, speed is a function of press design — once the plates are mounted, anilox rolls set, and registration dialled in, a modern flexo folder-gluer can process thousands of sheets per hour. Digital printing, by contrast, historically traded speed for flexibility: the ability to print variable data without plates came at the cost of slower linear throughput.
The current generation of UV digital corrugated printers has narrowed this gap significantly. By combining printhead arrays with higher native firing frequencies, wider print swathes, and — in single-pass architectures — fixed print bars spanning the full media width, these machines can now meet the throughput expectations of mid- to high-volume corrugated plants. The value proposition is not merely "digital quality at flexo speed," but rather "flexo-comparable throughput without the plate cost, storage, and mounting time that define flexo's total cost per job."
Speed Comparison Across Goking's Digital Corrugated Printer Series
The table below summarises the key speed parameters across Goking's three main product series and printhead families. Note that single-pass speeds are expressed in metres per minute (m/min), while multi-pass speeds are expressed in metres per hour (m/h) — reflecting the different ways each architecture achieves throughput.
| Series / Printhead | Architecture | Print Width Range | Speed Range | Colour Configuration | Best-Suited Volume |
|---|---|---|---|---|---|
| G-series Single-Pass (Epson) | ONEPASS — fixed print bars, media moves under stationary heads | 400–1,050 mm | 45–80 m/min | CMYK or CMYKW (24/32 heads) | High-volume continuous production; inline converting lines |
| GJ-series 2-in-1 (Epson) | Switchable single-pass / multi-pass | 400–525 mm | 45–70 m/min (SP) / 700–1,500 m/h (MP) | CMYK or CMYKW | Mixed-volume shops needing flexibility |
| J-series Multi-Pass (Epson) | Multi-pass — scanning carriage | 264–525 mm | 700–1,500 m/h | CMYK or CMYKW (up to 32 heads) | Short-run, high-mix, moderate volume |
| Seiko Printhead Series | Single-pass — single colour | 400–1,800 mm | 70–110 m/min | Single colour | Ultra-high-speed mono printing; wide-format |
| Xaar Printhead Series | Multi-pass | 200–400 mm | 500–1,000 m/h | CMYKW | Narrow-web, high-quality short runs |
All speed figures are nominal values. Actual throughput depends on substrate type, print mode (quality/production), image coverage, and board handling setup.
Reading the numbers correctly: A single-pass printer running at 70 m/min on 525 mm-wide board produces approximately 2,205 m² of printed area per hour. A multi-pass printer at 1,100 m/h on the same width produces approximately 577 m²/h. The single-pass machine is roughly 3.8 times faster in area output — but this comparison assumes continuous feeding without stops, which in practice depends on the upstream feeder and downstream take-off system configuration.
Single-Pass vs. Multi-Pass Architecture: The Fundamental Speed Equation
The throughput gap between single-pass and multi-pass digital printers is explained by their fundamentally different mechanical designs:
01
Multi-Pass
How Multi-Pass Printing Works
In a multi-pass system, the printhead carriage moves laterally across the substrate on a scanning axis while the media advances incrementally in the feed direction. Each pass of the carriage lays down a narrow swath of ink — typically a few centimetres wide, depending on the number of heads ganged on the carriage. To cover the full print width, the board must stop and advance multiple times, with the carriage scanning back and forth. This stepping motion limits linear speed: the combined time of carriage scan, carriage return, and media advance defines the cycle time per swath. Goking's multi-pass Epson-based machines achieve 700–1,500 m/h by optimising carriage acceleration, head firing frequency, and media transport synchronisation.
Multi-pass advantages include lower entry cost, easier head alignment maintenance, and the ability to print on slightly warped board — the scanning head can follow surface irregularities that a fixed bar might miss. These characteristics make multi-pass suitable for short-run, high-mix production where job variety, not pure throughput, drives the business case.
02
Single-Pass
How Single-Pass (ONEPASS) Printing Works
Single-pass architecture eliminates the scanning carriage entirely. Instead, fixed print bars — spanning the full media width — are mounted stationary above the board transport path. As the corrugated sheet or web moves continuously beneath the bars, all printheads fire simultaneously, depositing the complete image in a single transit. There is no reciprocating motion, no carriage return dead time, and no incremental stepping. The linear speed is limited only by the printhead's maximum firing frequency, the board transport system's stability, and the curing lamp's power density.
The G-series single-pass digital printer achieves 45–70 m/min on 400–525 mm widths and 55–80 m/min on wider 795–1,050 mm models. For five-color (CMYKW) output, 24-head and 32-head configurations are available, with the additional head row for white ink integrated into the fixed bar assembly. The result is full-colour output at throughput levels that approach the continuous-production speeds expected in high-volume corrugated converting plants.
How a High-Speed CE Certified Machine Using UV Ink Reduces Total Job Cycle Time
Throughput in a corrugated printing operation is not measured solely by linear metres per minute during printing. The complete job cycle includes pre-press preparation, machine setup, printing, and post-print handling. A high-speed ce certified machine using uv ink compresses time across multiple phases of this cycle:
Job Cycle Time Comparison: Traditional Flexo vs. High-Speed UV Digital
| Phase | Traditional Flexographic | High-Speed UV Digital (Single-Pass) |
|---|---|---|
| Pre-press / plate making | Plate design, photopolymer processing, mounting — hours to days per design | RIP processing only — minutes from file to print-ready |
| Job changeover | Plate removal, new plate mounting, registration, colour adjustment — 20–40 min | Approximately 1 minute — RIP software switch, no mechanical change |
| Printing (per 1,000 sheets, 525 mm width) | Minutes — limited by mechanical press speed | Seconds — 45–70 m/min continuous throughput |
| Post-print curing / drying | Water-based ink drying may require heated dryers and cooling time before stacking | Instant UV curing — boards can be stacked immediately downstream |
The one-minute job changeover capability is especially significant for plants that process many short-run orders per shift. In a flexo environment, 10 job changes at 30 minutes each consume 5 hours of a shift in non-productive setup time. On a digital press with approximately 1-minute changeovers, that same 10-job shift loses only 10 minutes to setup. The recovered production hours translate directly into additional billable output.
Seiko Printhead Technology: Achieving the Highest Linear Speeds
Among Goking's printhead options, the Seiko-based series delivers the highest nominal linear speed: 70–110 m/min. These machines are configured as single-pass, single-colour systems with 4 to 18 Seiko printheads mounted on fixed bars covering print widths from 400 mm up to 1,800 mm — the widest format available across Goking's product range.
Why single-colour, high-speed printing matters in corrugated production:
- Logistics coding and batch marking: High-volume corrugated plants often need to print variable data — batch codes, production dates, serial numbers, barcodes — at line speed on boxes moving through the converting line. A single-colour Seiko printer operating at up to 110 m/min can keep pace with folder-gluer output without becoming the rate-limiting step.
- Wide-format single-colour graphics: For corrugated displays, bin boxes, and industrial packaging where a single brand colour or black text on kraft is sufficient, the Seiko platform provides cost-effective throughput on board up to 1,800 mm wide.
- Inline integration: Because the print bar is stationary and the board moves continuously, a Seiko printer integrates naturally into existing conveyor lines, die-cutters, and material handling systems without the reciprocating motion that complicates multi-pass integration.
For converters whose volume is driven by high-speed mono printing on wide corrugated formats, the Seiko printhead series represents the top of Goking's speed range. The trade-off is colour capability — single-colour only — which means Seiko is typically deployed as a complementary machine alongside a full-colour press, not as a standalone replacement for all printing needs.
Digital Inline Integration: Extending Speed Beyond the Print Zone
A fast print engine is only as productive as the material handling system that feeds it and takes boards away. One of the architectural advantages of a high-speed ce certified machine using uv ink — particularly in single-pass configuration — is its ability to integrate with downstream converting equipment to form a continuous production line.
Goking's digital printers support connection to inline production lines and ERP systems, enabling:
- Print-to-slotter integration: Boards exit the UV curing zone and enter a slotter or die-cutter without intermediate stacking. This eliminates a material handling step, reduces labour, and allows the entire converting sequence — print, cure, cut, crease — to occur in a single linear flow.
- ERP-driven job sequencing: When the printer's RIP is connected to the plant's ERP or production management system, job queues can be loaded and prioritised automatically. The digital press processes jobs in sequence without operator intervention at each changeover, further compressing the non-productive gaps between orders.
- Just-in-time production: Because there is no plate inventory to manage and no setup time, a high-speed digital printer can produce orders in the sequence they are needed downstream — reducing work-in-progress storage and the associated floor space and handling cost.
The single-pass product category provides an overview of Goking's fixed-bar digital printers designed for inline integration, including both standard and wide-format configurations.
CE Certification at Speed: Safety Systems for High-Throughput Operation
Operating a printer at 70–110 m/min demands safety systems that are responsive, fail-safe, and compliant with EU machinery safety standards. CE certification for a high-speed digital press involves more than electrical safety — it encompasses the entire safety architecture of the machine, including guarding, emergency stop circuits, light curtains, and control system reliability.
Relevant standards and their practical implications for high-speed operation include:
- EN ISO 13849-1 (Safety-related parts of control systems): Defines Performance Level (PL) requirements for safety functions. On a high-speed single-pass printer, the emergency stop system must achieve a PL rating appropriate to the risk — typically PL d or PL e for the main drive and print zone guarding — meaning the control circuit is designed with redundancy and diagnostic coverage that makes a dangerous failure extremely improbable.
- EN 60204-1 (Electrical safety of machinery): At sustained high throughput, electrical cabinets, servo drives, and UV curing lamp power supplies generate heat and draw significant current. Compliance ensures that wiring, protection devices, and thermal management are engineered for continuous-duty operation, not intermittent use.
- EN ISO 13857 (Safety distances): Defines minimum clearance between moving parts and operator access points. For a machine running at 110 m/min, reaction time from guard opening to full stop must be short enough that the stopping distance does not exceed the safety distance — otherwise the guard is ineffective. This drives the specification of fast-acting brakes and safety-rated drive monitoring.
Goking's CE-compliant digital printers are manufactured at a 10,000 m² facility in Dongguan, where production processes are aligned with CE conformity assessment procedures. The manufacturing capability page provides detail on the quality systems and testing infrastructure that support sustained compliance.
Choosing the Right Speed Tier: Decision Factors for Corrugated Converters
Selecting between multi-pass, single-pass, and Seiko-based speed tiers is not a matter of "faster is always better." The right choice depends on the converter's order profile, substrate mix, colour requirements, and downstream process integration:
| Operational Profile | Recommended Speed Tier | Rationale |
|---|---|---|
| Many short-run jobs (<500 sheets each), high SKU variety, frequent changeovers | Multi-pass (J-series), 700–1,500 m/h | The one-minute changeover benefit dominates; pure printing speed is secondary when changeover time is the bottleneck |
| Medium to long runs, CMYK or CMYKW, moderate width (264–525 mm) | Single-pass (G-series), 45–70 m/min | Continuous throughput without carriage-return dead time; full-colour capability at production speed |
| Mixed job types — some short, some long; need flexibility | 2-in-1 (GJ-series), switchable SP/MP | Single architecture that covers both speed tiers; switch modes per job requirement |
| Ultra-high-speed, single-colour, wide-format (up to 1,800 mm) | Seiko series, 70–110 m/min | Highest linear throughput; single-colour is sufficient for batch coding, logistics marking, wide-format mono graphics |
| Narrow-web (200–400 mm), five-colour short runs | Xaar series, 500–1,000 m/h | Purpose-built for narrow-web with Xaar grayscale head technology |
Practical consideration: Many mid-size corrugated converters operate a combination of machines — a single-pass system for the high-volume colour work and a Seiko mono printer for coding and wide-format jobs. This hybrid approach balances throughput with capital deployment, allowing each machine to operate in its efficiency sweet spot. The GJ-series 2-in-1 printer offers a more compact version of this concept, with switchable single-pass and multi-pass modes in a single machine frame.
FAQ: Common Questions About High-Speed CE Certified UV Ink Digital Printers
What is the practical throughput difference between single-pass and multi-pass digital printers?
As a general comparison, a single-pass printer at 70 m/min on a 525 mm web produces approximately 2,205 m²/h of printed area. A multi-pass printer at 1,100 m/h on the same width produces approximately 577 m²/h. The single-pass machine delivers roughly 3.8 times the area throughput under continuous-feed conditions. However, single-pass machines have higher head-count requirements and stricter board flatness tolerances, so the appropriate choice depends on the production environment and order profile — not just the speed number.
Does higher speed affect print quality?
In single-pass architecture, linear speed is not inherently linked to print resolution — the printhead firing frequency and the board feed speed are synchronised electronically. At the rated speed range (45–80 m/min for Epson-based G-series machines), the control system maintains the correct dot placement timing. Exceeding the rated speed would result in under-firing (gaps in the image) or smearing if curing is incomplete, which is why operational speed ceilings are specified and should not be exceeded. On multi-pass machines, higher speed modes typically involve fewer carriage passes and larger step increments, which can reduce apparent resolution — hence the distinction between "quality mode" and "production mode" in RIP software settings.
Can a high-speed UV digital printer handle warped corrugated board?
Board flatness is more critical on single-pass machines than on multi-pass machines. A single-pass fixed print bar relies on a consistent gap between the nozzle plate and the substrate surface. If the board is significantly warped, the gap varies — and at the shallow depth-of-field typical of piezoelectric inkjet heads, this can cause dot misplacement and banding. Multi-pass machines with scanning carriages can be configured with a slightly larger head gap because the carriage's mechanical design can accommodate minor surface variation. For plants that frequently process lower-grade or inconsistently flat board, multi-pass may be the more robust starting point before investing in board conditioning or upgrading substrate sourcing.
How does the one-minute job change work in practice?
The job change process on Goking's digital printers is software-driven. When the operator loads the next print file into the RIP, the system processes the new image data, applies the colour profile, and queues it for production. There is no physical tooling to change: no plates to mount, no anilox rolls to swap, and no ink trays to clean between colours. The transition from Job A to Job B typically takes approximately 60 seconds — primarily the time required for the RIP to rasterise the incoming file and for the operator to confirm the job parameters on the control interface. On the core features page, additional operational details about Goking's workflow software are described.
What makes a UV digital printer faster than a water-based digital printer?
The speed advantage is primarily in post-print handling, not in the print engine itself. UV-curable inks cure in a fraction of a second under UV light exposure, which means boards can be stacked, fed into a die-cutter, or palletised immediately after exiting the print zone. Water-based inks require evaporation or absorption-based drying, which often involves heated dryers, extended conveyor paths, or dwell time before downstream handling. In a high-speed production line, UV curing eliminates the drying bottleneck that would otherwise force the line to slow down or add buffer storage between print and converting stations.
Key takeaway: A high-speed ce certified machine using uv ink addresses the throughput challenge that has historically limited digital adoption in volume corrugated production. By offering multiple architecture options — multi-pass for flexibility, single-pass for continuous throughput, and Seiko for maximum speed on wide-format mono work — Goking's product range allows converters to match their speed investment to their specific order profile. The CE-certified build provides regulatory assurance for EU market deployment and, equally important, the safety architecture required for sustained high-throughput operation in a busy converting plant. For converters evaluating a move from flexo to digital, the speed comparison is not about matching flexo's peak mechanical rate — it is about measuring total job cycle time, including setup, printing, curing, and handling, and recognising that digital compresses the non-printing phases in ways that flexo cannot.
