Nabe Process with Asahi improves flexographic plates

Overall number of press stops for plate cleaning or quality adjustment significantly reduced

Japanese Printing Company Nabe Process, improves efficiency with Asahi Photoproducts AWP flexographic plates.

Asahi Photoproducts, a pioneer in flexographic photopolymer plate development, today reported that Nabe Process a major Japanese printing company, has tested Asahi’s AWP CleanPrint water-washable flexographic plates against conventional solvent-based plates to measure differences in quality and productivity between the two. The AWP plates, which were made with CrystalCleanConnect, demonstrated a significant improvement in print quality and productivity compared to the conventional solvent-developed flexographic plate. CrystalCleanConnect is a brand-new offering jointly developed by Asahi Photoproducts and ESKO that automates the platemaking process, reducing steps from 17 to 1 and dramatically reducing potential for error.

According to Nabe Process, the test was conducted using actual customer work, and all times and steps were carefully documented. It was notable that the Asahi AWP plates had excellent ink transfer, which contributed to the overall improved quality and fewer press stops for plate cleaning and other quality issues.

The design chosen by Nabe Process, for this test contains fine highlights. To obtain the required quality with solvent-based plates, the press had to be stopped several times during the run to prevent such things as ink filling. This was not the case with the Asahi AWP water-washable plates which offer CleanPrint technology, originally developed by Asahi in order to improve the ink transfer from the plate surface to the printed material.

Yasuo Naka, general manager of Flexography Division, Nabe Process, commented “From this result, we were able to confirm that we can deliver more stable and higher quality printed products to our customers using Asahi’s AWP water-washable plates. With the conventional solvent plate, we also had more difficulty in the printing process due to mis-registration during printing.

With the Asahi AWP plates, however, that problem is resolved and productivity is dramatically improved. We are very happy with the performance of the AWP plates as a result. In addition, in the spring of 2021, we installed CrystalCleanConnect, a fully automatic plate-making device jointly developed by Asahi and ESKO. That has added to our overall quality and productivity, getting plates to press much faster, with less operator engagement time and with less opportunity for error. Based on these results, we are converting all of our flexographic plates to Asahi AWP water-washable CleanPrint plates, and we know our customers will be even more delighted than ever with the quality they receive from us.”

Yuzo Fujiki, chief technology officer, printing solution project, of Asahi Kasei Corporation, commented, “We were pleased to work with Nabe Process on this project to validate the excellent plate performance of our AWP water-washable plates in terms of both print quality and productivity. And we are thrilled that Nabe Process has chosen to create even more efficiency by installing the first CrystalCleanConnect system in the world, the industry’s first fully automatic water-washable plate-making device, developed in collaboration with ESKO. As we continue to work with forward-thinking companies like Nabe Process, we will also be working toward continouos improvement of print quality as well as keeping sustainability top of mind.”

Asahi’s CleanPrint flexographic printing plate has excellent ink transfer from the plate surface to the substrate, resulting in less ink remaining on the plate surface during and after printing compared with conventional solvent-based plates, dramatically reducing the number of press stops required for plate cleaning. In addition, the plate making process is water-based, using non-VOC based chemicals. And with the CrystalCleanConnect solution, which delivers ready-to-mount plates with the push of a button, platemaking time and labor is also dramatically reduced, resulting in a more efficient and cost-effective flexographic printing operation.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.

In an admittedly fragmented and textured terrain, this is the right time to plan your participation and marketing support communication – in our impactful and highly targeted business platform.
