The growing demand for increasingly higher speeds in the converting industry, namely the transformation of raw flexible materials such as plastic films, paper, and nonwovens into finished or semi-finished products, is not merely a race for speed’s sake. On the contrary, it represents a strategic imperative driven by the convergence of economic pressures, evolving market dynamics, and increasingly stringent operational constraints.
Why are converters constantly pushing the limits of their lines?
1. Cost reduction and economies of scale
- Lower unit cost: This is the most decisive factor. A converting line represents a significant capital investment. Increasing its speed allows for more units to be produced per hour, thereby diluting fixed costs (labor, energy, overhead, equipment depreciation) across a greater number of products, leading to a substantial reduction in unit cost per pouch, label, or package.
- Labor efficiency: A line operating at 600 meters per minute (mpm) produces twice as much as one running at 300 mpm, with the same number of operators. This improves labor productivity and reduces the labor share in the final product cost.
2. Meeting a rapidly evolving market
- Just-in-time (JIT) production: Brands and retailers are increasingly minimizing inventory costs and demanding quick turnaround. A converter capable of receiving an order and delivering within a week holds a significant competitive advantage over one that takes three. Production speed is critical to meeting these shortened lead times.
- Time-to-market for promotions: Seasonal promotions (e.g., holiday packaging) have narrow commercial windows. For brands, it is essential that their packaging suppliers are both responsive and efficient. Speed enables converters to react quickly and secure high-value, time-critical orders.
3. Maximizing asset utilization and productivity
- Return on investment (ROI): A multimillion-euro converting line generates value only when running. Maximizing operational speed means maximizing the return potential and shortening the payback period.
- Growth without physical expansion: In many cases, instead of installing a new line to double capacity, it’s more efficient to enhance the performance of existing equipment. This enables productivity growth without the need for new space, construction costs, or additional resources.
4. Competitive pressure
- Industry benchmarks: Speed has become a key performance indicator (KPI). If competitors are running jobs at 500+ mpm and you’re still at 250 mpm, you’re no longer competitive in terms of price or turnaround. At high volumes, this becomes a critical differentiator.
- Global competition: Converters no longer compete only locally. In a landscape of international supply chains, they face competition from overseas manufacturers investing heavily in high-speed technologies.
Why is inline flexographic printing the optimal solution for speed?
In the face of increasing competitive pressure, every component of the production line must deliver speed, stability, and reliability. The printing press is often the heart of the process. An inline flexographic press is not just a fast printing system, it embodies an entire production philosophy, perfectly aligned with the needs of the modern converter.
At the K 2025 trade fair in Düsseldorf, our company proudly premiered its latest generation of high-speed flexographic presses. Our booth, entirely dedicated to the theme “Need for speed,” attracted strong interest from industry professionals, thanks to the innovative solutions and extreme performance demonstrated by the machines on display.
1. The “inline” advantage: integrated and continuous production
Inline printing means the press is fully integrated into the converting line: the reel-fed material is unwound, printed, and immediately transferred to downstream processes (lamination, die-cutting, slitting, packaging) in a seamless flow.
- Elimination of logistical bottlenecks caused by intermediate storage and handling of semi-finished products.
- Increased productivity through synchronization of all line components, preventing the press from becoming a production bottleneck.
Our solutions presented at K 2025 clearly illustrated this concept, demonstrating how intelligent integration between printing and converting enables speeds far beyond current industry standards—while maintaining high quality and precision.
2. Mechanical design inherently suited to high speed
The mechanical nature of flexographic printing is designed for speed. It is a rotary, continuous-motion process with high-speed cylinders and no reciprocating movements that slow down other print technologies. The ink path is short and direct, ensuring stable and repeatable transfer even at high surface speeds.
At K 2025, we showcased these benefits live through technical demonstrations that drew numerous visitors to our booth, eager to experience the full potential of these solutions firsthand.
3. Advanced automation and rapid job changeovers
Modern flexo presses incorporate essential automation to maximize uptime:
- Automatic makeready: Features such as automatic impression setting (AIF) and camera-based registration systems (auto-register) reduce setup times from hours to just minutes.
- Sleeve technology: Lightweight, quick-change sleeves for plates and anilox rollers allow for fast, easy job changes.
- Automatic wash-up systems: Built-in cleaning systems allow for efficient cleaning of chambers and plates, minimizing downtime between jobs.
These features were at the core of our exhibition offering, underscoring how automation is no longer a convenience, but a critical enabler of continuous, high-speed production.
4. High-performance drying and curing systems
Speed is often limited by the ink’s drying capacity:
- High-efficiency drying: Hot-air dryers, often combined with infrared (IR) systems, ensure near-instant drying between color stations.
- Instant UV/LED curing: For UV/LED inks, curing is instantaneous, virtually eliminating drying constraints and enabling extremely high line speeds.
These technologies were key highlights of our K 2025 showcase, where we demonstrated how next-generation UV/LED systems can push speeds beyond 800 mpm, without compromising print quality.
5. High-precision web handling and tension control
At 600–800 mpm or more, the web moves through the press at extreme speeds. Maintaining tension and alignment is critical:
- Advanced tension control: Inline flexo presses are equipped with closed-loop tension systems using load cells and servo-driven rollers to ensure constant tension throughout the process.
- Web guiding systems: High-precision electronic and pneumatic devices maintain perfect material alignment, crucial for color-to-color registration and downstream accuracy.
Visitors at the fair witnessed first-hand the outstanding register stability of our machines at full speed, reinforcing our position as a technological leader in the industry.
6. Versatility across a wide range of substrates
Flexographic “kiss” printing, where the plate applies minimal pressure to the substrate, makes it ideal for thin films, stretch plastics, paper, and nonwovens. Even at high speeds, deformation is avoided. This allows a single machine to serve multiple markets and applications.
This versatility was among the most appreciated aspects by K 2025 attendees, who were drawn by the ability to cover a broad spectrum of applications with one advanced, flexible technology platform.
