Wallpaper printing technology and trends have evolved over the years, bringing about various methods and advancements to enhance the quality and customization of wallpapers. Wallpaper production involves reproducing images or designs onto large-width on continuous rolls of substrates. Often, these printed rolls are provided as adhesive-backed materials for home or commercial establishment decoration.
Traditionally, high-volume production for the home furnishing and decoration sector used gravure printing. However, new technologies using inkjet industrial printing, together with ease of application and removal trends for do-it-yourself (DIY), are shaping the global market. Recently, Indian distributors of imported wallpapers have also evinced greater interest in their local production using digital industrial printing.
Durst, a manufacturer of digital printing and production technologies, has adapted its digital inkjet printing technology to wallpaper printing. A shift from conventional screen and gravure printing presses to more sustainable production processes using less water and energy consumption, which also enable smaller volumes to be produced inexpensively without warehousing costs is accelerating. Other important drivers are the use of new environmentally friendly materials that are odor-free and can be made from recycled raw substrates.
The Durst Alpha Wallpaper edition is among the most productive digital printing systems on the market, with a production capacity of over 1,500 rolls per day or up to 1.2 million linear meters per year. In addition to productivity and color consistency across the entire print width or run length, the total cost of owner (TCO) is also important for producers. This is where Durst has another advantage with its expertise in print quality and ink consumption. With Durst Alpha Pigment Inks, Durst also offers fully water-based inks in eight colors that enable ‘healthy sustained wallpaper,’ with a natural and high-quality look.
Based out of Blackburn, Lancashire, UK Graham & Brown, a provider of printed interior decoration material has invested in Durst’s Alpha Wallpaper edition technology. “The potential is enormous,” said Sam Dobson, operations director for Graham & Brown. “Digital is an extremely important technology for the wallpaper industry. It’s really about print-on-demand, reducing print run-lengths, and giving a more bespoke offering to customers. At the moment, this industrial-scale digital production has filled the gap between the high run lengths of conventional printing and the low volumes of our previous digital machines.
“We see the Durst as a complementary technology that has many environmental and other benefits. As one example, the main resource we need to power the machine is electricity, and all of that is renewable. For the last year, all of our digital production – representing 35% of the Graham & Brown brand offer – has been carbon zero,” Dobson claims.

There are different printing methods for wallpaper, including digital printing, screen printing, offset, and gravure printing.

The choice depends on factors like durability, ease of installation, and the desired look.
