In recent years, the packaging industry has experienced steady growth in the demand for paper used to fill empty spaces inside shipping packages. The continuous expansion of e-commerce and logistics has significantly increased the need to produce large volumes of printed paper quickly, reliably, and cost-effectively.
In this context, many companies ask the same question: is it more advantageous to use a flexographic printing press or an industrial inkjet system?
There is no universal answer. The most suitable choice depends primarily on the production requirements. Each technology offers specific advantages and is designed for different applications.
Flexography and industrial inkjet: two technologies designed for different production needs
Industrial inkjet is now a highly advanced printing technology, particularly suited to applications requiring variable data printing, extensive customization, frequent artwork changes, or short production runs.
Flexographic printing, on the other hand, is designed to meet entirely different production requirements: continuous operation, high production speeds, very long print runs, and low operating costs. For this reason, these two technologies should not be considered direct competitors, but rather complementary solutions developed to address different manufacturing needs.
Whenever the objective is to produce thousands of meters of printed paper every day while maintaining high productivity and keeping operating costs under control, flexography continues to represent the most advantageous technological solution.
The requirements of modern paper converting
In production lines dedicated to manufacturing void fill paper for packaging, printing is not an isolated operation but an integral part of the entire converting process. The printing press must therefore integrate seamlessly with the production line without becoming a bottleneck.
Key performance requirements include:
- high production speeds;
- perfect synchronization with the converting line;
- consistent print quality;
- reliable operation over multiple shifts;
- reduced waste;
- rapid start-up and fast process stabilization.
These factors ultimately determine the overall productivity of the manufacturing line.
Why flexography remains the industry benchmark
One of the greatest advantages of flexographic printing is its ability to maintain consistent print quality throughout very long production runs.
Once the production parameters have been optimized, the interaction between the anilox roll, printing plate, printing pressure, and ink management system creates an extremely stable and repeatable process. For production managers, this means greater process predictability, fewer corrective interventions, and reduced machine downtime.
Modern flexography also combines two characteristics that are often considered mutually exclusive: high production speed and outstanding print quality. The latest technological developments demonstrate that excellent register accuracy and uniform ink transfer can be maintained even at maximum production speeds.
The role of water-based inks
Ink selection is another critical factor in the packaging industry.
Water-based inks have become the preferred solution for many paper converting applications thanks to their sustainability, safety, and compatibility with packaging intended for food-related supply chains.
Flexographic printing integrates perfectly with water-based ink systems, delivering excellent print quality and outstanding process stability even during continuous production.
What a modern flexographic press should offer
Meeting the demands of today’s paper converting industry requires more than advanced printing technology.
The press must be engineered to integrate seamlessly into the production line while providing:
- high register accuracy;
- stable ink transfer;
- rapid start-up;
- reduced waste;
- reliable multi-shift operation;
- easy operation and maintenance;
- outstanding performance even at maximum production speeds.
Only when all these elements work together can a truly efficient production process be achieved.
Giugni’s solution: New Miniflex® 528
To meet these requirements, Giugni® has developed the New Miniflex® 528, a flexographic printing press specifically designed for integration into automated paper converting lines.
One of its most significant features is its maximum speed of 700 meters per minute, enabling seamless integration with today’s high-capacity production lines. However, speed is only one of the characteristics that define this machine.
Its robust mechanical design, precision-engineered printing units, and stable ink delivery system ensure consistently high print quality throughout extended production runs, minimizing adjustments and contributing to uninterrupted production.
Compatibility with water-based inks also makes the New Miniflex® 528 particularly well suited to packaging and paper converting applications, where reliability, safety, and print quality must be combined with high production throughput.
Technology selection should follow the production process
The comparison between flexography and industrial inkjet cannot be reduced to a simple choice between two competing technologies. Industrial inkjet is an outstanding solution whenever added value comes from personalization, variable data printing, or short production runs.
However, when the manufacturing process requires continuous production, high output volumes, competitive operating costs, and consistent long-term print quality, flexography continues to offer advantages that are difficult to match. This is why many companies in the paper converting industry continue to invest in flexographic printing systems fully integrated into their production lines.
Machines such as the New Miniflex® 528, capable of operating at speeds of up to 700 meters per minute while maintaining excellent print registration, process stability, and operational reliability, provide a practical solution to the demands of modern industrial production of printed void fill paper.
Ultimately, selecting the most appropriate printing technology depends not only on the achievable print quality but also on the ability of the entire production system to deliver continuity, efficiency, and long-term competitiveness.
