New format, new opportunities
The arrival of the Komori 37-inch press at De Groot
When De Groot decided to invest in a Komori 37-inch press, the objective was clear: create more flexibility in production while increasing efficiency and material usage. The installation of the press marked an important step in the company’s long-term strategy, filling a gap between conventional sheetfed formats and large-format production.
A noticeable arrival on the shop floor
The arrival of the Komori 37-inch press was an event in itself. For several days, preparations were visible on the production floor: the area was cordoned off, a concrete beam was placed, and logistics were carefully planned. When the trailers arrived with the various components of the press, employees gathered to follow the process.
“An installation like this is always something special,” says owner Anton de Groot. “Everyone is curious, and because we approach everything from a technical perspective, people want to understand exactly what is happening.”
The press was assembled step by step inside the production hall, with the entire process captured in a time-lapse recording. For several team members, the installation was a continuation of an earlier experience.
“We had already seen this machine during our visit to Komori in Japan. Seeing it there and now having it here on our own shop floor made it very tangible.”
Thorough preparation as the foundation
Technical manager Vincent Brouwer coordinated the installation process in close cooperation with Komori and the involved suppliers. All technical aspects were prepared in advance, including power supply, water connections and network infrastructure.
“Vincent wanted everything to be right before the first component arrived,” Anton de Groot explains. “By preparing thoroughly, we created the conditions for Komori’s technicians to work efficiently during installation.”
In parallel, six printers followed an intensive training programme at Komori. During this week, they became familiar with the press operation, automation and maintenance procedures. This early investment in knowledge proved essential once the press went into production.
Flexibility during installation
Despite detailed planning, practical challenges inevitably arose during installation. Certain auxiliary equipment did not fit through the originally planned route. Adjustments were made on the spot, without disrupting the overall process.
“We had mapped everything out beforehand, but reality is always slightly different,” says Anton de Groot. “What mattered was the flexibility — both on our side and Komori’s. Some elements were adjusted compared to the original drawings, while the core setup remained exactly as intended.”
From start-up to stable production
The Komori 37-inch press has been in production since July and has been running in a three-shift operation since October. In the first few months alone, the press produced approximately five million impressions.
The press is operated by a relatively young team of six printers. Some already had experience with Komori equipment, while others transitioned from different press platforms. Although the press is designed as a one-man operation, additional support is provided for larger jobs that require frequent pallet changes.
Knowledge sharing plays an important role in daily operations. The team uses a dedicated WhatsApp group to exchange tips, settings and solutions.
“If someone discovers an optimisation or runs into an issue, it’s shared immediately — often with a photo,” Anton de Groot explains. “Sometimes the solution even comes from someone who is off-site.”
