Digital print for corrugated

The future condition of things

My great grandfather, Thomas Kirby, once said, “Wisdom lies not in regretting the inevitable but in adapting oneself to the altered condition of things.” He printed this statement in his publication, “Saddlery and Harness,” in response to the uproar from his readers after the first car was seen in Walsall, UK in 1896. The internal combustion engine was perceived as the beginning of the end for the local allied horse trades, and consequently, his readers wanted to destroy its threat to protect their equine-related businesses. Thomas was a brave man to challenge his customers’ cynicism by urging them to change! In many ways I relate Thomas’ statement to the digital world we live in today as it has challenged traditional analog methods. From smartphones to the internet and Amazon, we have witnessed dramatic change in the last 25 years or so as a result of digitized technologies. Buying a digital printer is not like buying early cars where the choice in 1896 was very limited. Manufacturers, brave enough to invest the vast sums required for the R&D to develop the latest digital print technologies, have been met with trepidation from potential buyers of their equipment due to a history of failed or unstable installations. This has not been good for the future confidence of digital in the corrugated sector, but the tide is turning.

So, which digital print machine do I buy? Despite the technology’s relative infancy, the choice of digital printers is already so widespread that you have to understand every detail of what you are buying before making a decision. Getting it wrong is likely to be very costly! Consequently, let’s start by looking at the platform technologies in brief.


These machines were developed specifically for the large format signage and POS sectors, and they have played a big part in the demise of new ultra-large format litho machine installations. Typically, the most modern multipass machines will happily run at between 500 and 1,000 square meters an hour using UV inks at very high quality.

Single Pass Sheet Fed

These state-of-the-art high-volume production machines use single pass technology where the sheet passes under the print heads once and is finished. More suited to packaging and long-run PoS specifications, the print quality is slightly lower than their multi-pass brothers, but with output at between 5,000 to 7,000 square meters an hour, it is good enough to challenge mid-quantity, high-quality post-print (HQPP), and litho laminated alternatives. Machines are available with UV, water-based or hybrid inks.

Web Digital

Wide web digital (2.8meter) is the Formula 1 for digital print output at over 25,000 square meters an hour, but maybe controversially, I do not see pre-printed web digital reels being aligned with the corrugating process. Using water-based inks, this impressive marvel of innovation meets its nemesis when introduced to a corrugator where the manufacturing principles have ostensibly remained the same for over 100 years. Steam, heat, pressure, and waste are all enemies of digital, so I relate it to putting a Ferrari engine in a Model T Ford – surely, somewhat futile on compatibility grounds! Corrugator technology has to evolve to unlock the pinnacle of opportunity that digital brings.


Sustainability will be the focus for generations to come, but how does this influence which machine you should purchase? UV ink facilitates a more stable control of the equipment during printing, but it is carcinogenic and not suitable for direct food contact packaging, although in some cases it is food compliant for secondary packaging. There is also an inherent odor with UV ink, it is glossy, and I’m not so sure these factors will be tolerated in the market for the long term. UV ink for display products is widely accepted and does not pose the same concerns. Nevertheless, water-based ink technologies are developing rapidly, but the machinery to cater for the deliverance and drying of the ink is more complex and expensive. Despite water-based inks being less expensive than UV inks, the energy required to dry them at high speed can be alarming. So, weighing up the many pros and cons of water-based or UV technology before investing is critical to the market, you are most focused to serve in the longer term.

Adding Value

Having purchased your new asset, requiring the forethought and vision to upsell digital capabilities are fundamental to success. Make no mistake; digital is not a replacement for your existing HQPP or litho processes, rather a complementary addition to your sales weaponry that will give newfound opportunity. More often than not, multiple prints for traditional corrugated packaging, eCommerce packs, personalization needs, print-on-demand, and greater consumer interaction are all areas that can be serviced by digital more efficiently than traditional analog. Nonetheless, creating such a solution to generate greater consumer demand through the print innovation should never be undersold. After all, digital has provided the opportunity that would otherwise have been missed. It is for this reason that commoditized pricing for digital should not be driven by the misguided strategy for it to replace traditional analog print.

Sales Know-How

Knowing your target markets and understanding the foibles of digital are fundamental to the successful development of hitherto untapped opportunities. An analog mindset has no place in the digital world, so understanding where each technology prevails is a good place to start, but never discount analog from being a positive contributor to your digital journey. Mixing analog and digital technologies can often provide the ultimate solution; for instance, an eCommerce box could have litho lamination on one side and then the personalized, interactive or topical subject matter digitally printed on the inside. Voila! The best of both world’s working in harmony to provide a value-added solution. Nonetheless, be aware because digital ink costs can disproportionately skew the ability for it to compete with analog. This can be problematic at enquiry stage where ink coverage on a litho laminated specification doesn’t impact the unit cost whether it is 25% coverage or 100% coverage, but digital ink does. This then gives a problem right back at enquiry stage where more often than not, ink coverage is not known for a printed box and therefore the commercial offering is wisely based on 100% coverage unless the artwork is existing. Clearly then, estimating all digital specifications at 100% ink coverage is going to prevent it replacing analog even before the full artwork facts are known! The solution here is to re-educate the individuals and processes that take place pre-press. For instance, packaging sales representatives, brand owners, buyers, artwork creators, and marketers need to understand that digital price sensitivity can often be impacted by poor forethought. It is for this reason that all parties must be aligned to maximize the digital advantage.

The Consumer

Notwithstanding the above considerations, do not underestimate the power of the consumer. The need for sustainability, waste reduction, greater product knowledge, interaction, convenience, and brand recognition in packaging are all demands that we see being driven by the consumer. Digital print on corrugated satisfies all of these trends, and it is here to stay!

2023 promises an interesting ride for print in India

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. While the print and packaging industries have been resilient in the past 33 months since the pandemic lockdown of 25 March 2020, the commercial printing and newspaper industries have yet to recover their pre-Covid trajectory.

The fragmented commercial printing industry faces substantial challenges as does the newspaper industry. While digital short-run printing and the signage industry seem to be recovering a bit faster, ultimately their growth will also be moderated by the progress of the overall economy. On the other hand book printing exports are doing well but they too face several supply-chain and logistics challenges.

The price of publication papers including newsprint has been high in the past year while availability is diminished by several mills shutting down their publication paper and newsprint machines in the past four years. Indian paper mills are also exporting many types of paper and have raised prices for Indian printers. To some extent, this has helped in the recovery of the digital printing industry with its on-demand short-run and low-wastage paradigm.

Ultimately digital print and other digital channels will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future. For instance, there is no alternative to a rise in textbook consumption but this segment will only reach normality in the next financial year beginning on 1 April 2023.

Thus while the new normal is a moving target and many commercial printers look to diversification, we believe that our target audiences may shift and change. Like them, we will also have to adapt with agility to keep up with their business and technical information needs.

Our 2023 media kit is ready, and it is the right time to take stock and reconnect with your potential markets and customers. Print is the glue for the growth of liberal education, new industry, and an emerging economy. We seek your participation in what promises to be an interesting ride.
