Polar AirGo Jog installed at photo service provider CEWE

Four years of cooperation

The AirGo Jog is an innovation for postpress finishing from Polar Mohr.

The AirGo Jog – an  innovation for postpress finishing from Polar Mohr, a Hofheim (Germany)-based machine building and technology company — was first presented at the end of 2020 as a ‘milestone for autonomous processing’. The development was carried out in cooperation with online photo service provider CEWE. After a successful field test, two examples of the jogger are now in use.

The search for a new ventilation system brought CEWE and Polar together four years ago. The goal was to find a solution for B2 formats that would allow the sheets to be removed and processed in layers without having to change the sequence of the sheets. The place of operation: CEWE’s production facility in Germering, which specializes in medium format. All orders are processed there in intermittent three-shift operation.

Polar, with CEWE as field test customer, developed a fully autonomous system: The AirGo Jog fully automates the loading and jogging process. First, a Transomat loader takes entire layers from a pallet and transports them to an automatic jogger. There, the usual jogging process first begins — with the crucial component: an aeration system. While the material is jogged, air is blown into the cutting layer. This enables a first-class, edge-precise jogging result. The jogged cutting layer can then be cut in one.

The name of the AirGo Jog is derived from the system’s essential elements: air and jogging, as Indian Printer and Publisher had earlier reported when the device was first announced and premiered at the HD Innovation Week in October 2020. 

Successful project even in times of crisis

“We are delighted that the AirGo Jog has finally arrived on the market. The close cooperation with CEWE was a great help in overcoming last difficulties — the successful field tests now confirm the success,” says Sales manager Markus Judel. The project period since 2020 was a particular challenge. “The past two to three years were conceivably complicated, there was the pandemic and later major supply chain problems,” recalls Frank Schulz, technical manager of CEWE’s Germering site, who steered the project. “The fact that it was still successfully implemented was only possible because of the great flexibility on both sides.”

In the meantime, the jogger in Germering is no longer just running in test mode, but in regular operation: around the clock, with a cycle time of 60 to 90 seconds, it is a real efficiency miracle. CEWE retrofitted a second model at the end of 2022. “Almost all of our projects are processed with the AirGo Jogs,” says Frank Schulz.

The program includes grammages from 150 to 250 grams; in tests, even papers with only 80 grams could be jogged successfully. The Polar system is convincing all around, he says. “We were able to greatly reduce the number of FTEs, the system runs more reliably and the ventilation result is optimized,” Schulz says. “In addition, the AirGo Jog is very compact in its design and does not require much space.” Polar systems are popular at CEWE. Several cutting units, two of which are currently equipped with an AirGo Jog, are located in Germering.

In 2024, we are looking at full recovery and growth-led investment in Indian printing

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. It created the category of privately owned B2B print magazines in the country. And by its diversification in packaging, (Packaging South Asia), food processing and packaging (IndiFoodBev) and health and medical supply chain and packaging (HealthTekPak), and its community activities in training, research, and conferences (Ipp Services, Training and Research) the organization continues to create platforms that demonstrate the need for quality information, data, technology insights and events.

India is a large and tough terrain and while its book publishing and commercial printing industry have recovered and are increasingly embracing digital print, the Indian newspaper industry continues to recover its credibility and circulation. The signage industry is also recovering and new technologies and audiences such as digital 3D additive printing, digital textiles, and industrial printing are coming onto our pages. Diversification is a fact of life for our readers and like them, we will also have to adapt with agility to keep up with their business and technical information needs.

India is one of the fastest growing economies in nominal and real terms – in a region poised for the highest change in year to year expenditure in printing equipment and consumables. Our 2024 media kit is ready, and it is the right time to take stock – to emphasize your visibility and relevance to your customers and turn potential markets into conversations.
