Digidelta, a specialist manufacturer of digital printing, decoration, visual communication, and textile materials, recently used its BIOND Bio-Print Film P HT BF 90 White Matte film to produce a set of stunning wall graphics for classrooms at a primary school in South Africa.
Each year, the Fespa Foundation mobilises international printing industry partners to contribute products, materials, and services in the months leading up to the Fespa Global Print Expo in a sustainable manner.
For its 2026 edition, the initiative took on the theme of the ‘Big Animal School’, centred around a collective effort to rebuild classrooms in South African primary schools. Digidelta’s role was to both design and produce educational wall graphics for the under-renovation Batau Primary School.
Due to the classroom setting where the graphics would be installed, this posed an additional challenge for Digidelta. Strict rules and regulations meant it was limited to only using materials and consumables that ensure the printed applications would be suitable and safe in this environment.
With more than 40 years’ experience in the printing sector, coupled with far-reaching knowledge of print materials and hardware, Digidelta was ideally placed to support.
After evaluating the project and how to deliver the best possible quality, the company’s expert team at its Torres Novas site in Portugal settled on BIOND Bio-Print Film P HT BF 90 White Matte.
Part of Digidelta’s BIOND range of bio-based printable films, the product is free from plasticisers and has a 90-micron thickness, permanent high tack adhesive and a bubble-free liner.
Together, these features ensure high stability during printing and place the product as an ideal solution for a wide range of promotional applications, including interior wall graphics. In addition, the film carries an EN†13501-1:2018 reaction-to-fire classification as proof of its safety for use across various indoor environments.
“At Digidelta, we have always believed that the purpose of what we manufacture goes beyond its technical performance. We created BIOND because we believe it is possible to make materials that are better for the environment and for the people who live alongside them,” explained Armando Mota, CEO of Digidelta.
“When the Fespa Foundation came to us with this project, it felt like a direct expression of that belief. A bio-based film, in a school, on walls that children will look at every day for years. That is the world we are trying to help build.”
However, material was only part of the equation, with Digidelta also tasked with using hardware that would deliver high-quality output.
Having served as a Mimaki distributor in the Iberia region for almost 25 years, Digidelta opted for the company’s UCJV330 print and cut UV LED inkjet printer.
The flagship UV model from Mimaki can print on media up to 1mm thick and as wide as 1.6m with the 130 model or 1.6m on the 160 machine. Other features include a maximum cutting speed of 300mm/s and a range of colour options across various inksets.
To meet the strict criterion of printed applications inside classrooms, Digidelta chose to run with Mimaki LUS170 inks, which carry the key UL Greenguard Gold certification – regarded as one of the most demanding standards for low emission of volatile organic compounds (VOCs) in sensitive environments, including spaces where children are present.
Each Batau classroom is dedicated to one ‘Big 5’ animal and a specific educational focus. The Lion Classroom focuses on leadership and confidence; the Elephant Classroom wisdom and strength; the Leopard Classroom agility and creativity; the Rhino Classroom strength and authority; and the Buffalo Classroom teamwork and resilience.
“We wanted each classroom to feel educational and inspiring, rather than simply decorative,” said Fábio Costa, marketing manager at Digidelta. “Each animal theme represents different qualities such as teamwork, creativity and leadership, helping create an engaging environment for students.”
After the graphics were produced in-house by the Digidelta team, they were shipped to the 2026 Fespa Global Print Expo – where Digidelta exhibited – and was then sent on to the school in South Africa ready for installation in classrooms later this year.
