Fujifilm’s award-winning factory in Broadstairs, UK, manufactures high performance inks for a range of markets, including Uvijet wide format UV inkjet inks, and Sericol screen and flexo inks. The company has implemented a number of sustainability initiatives over the last ten years, and more recently the recruitment of Antonina Realmuto as Group Sustainability Director, and Craig Milsted as Sustainability Advisor for the site, has brought about a much greater focus to accelerate change towards more sustainable operations.

When it comes to sustainability and protecting the earth, it’s important for us all to do more. Whether it’s consuming fewer products, opting for products with less packaging, or reducing waste – we must all play our part.

Fujifilm’s ink R&D and manufacturing facility in Broadstairs, Kent, has regularly made the news as a three-time winner of the UK’s Best Factory Award in 2011, 2013 and 2015, but it is for its sustainability initiatives that it is now rapidly creating waves.

Craig Milsted outlines the initiatives that have been implemented so far: “With the recent changes in personnel, including my own role, there is now a renewed focus on sustainability, and therefore a tremendous amount of work going on behind the scenes to help us operate more sustainably. This work is ongoing, but we have made a number of notable recent changes to our equipment and processes which are enabling us to operate in a more environmentally friendly way.

Big energy savings

“Firstly, we have massively cut back on our conventional energy use and have instead turned to alternative energy sources to help power our site. Back in 2016, we started to buy renewable electricity to power our factory, and in the same year installed many solar panels on the grassy grounds of our site. But in March this year, we expanded our solar power generation with the addition of panels on our site roof.

“We have an ongoing objective to generate more solar power over time and steps towards achieving this goal include reviewing our current processes and equipment. Through these checks, we have found that the solar panels on the roof are more effective than the ones on the ground, so we have repaired and improved those on the grass, while also scoping out new areas on our site where panels can be installed to effectively generate more solar power in the future.

“Our efforts so far have been successful – this year in June alone, our solar panels produced 82,240 kW of power. This is enough to power a typical  UK household for 26 years and is also 181% more power than the 29,185 kW produced in June 2021.

Since 2013, we’ve significantly cut back on the waste produced at our ink factory, and last year (2021), 689.7 tonnes of waste produced on site went for recycling.

Craig Milsted | Sustainability Advisor, Fujifilm Speciality Ink Systems

“Another way that we have saved on conventional energy is by turning our factory HVAC (heating, ventilation and air conditioning) systems off overnight, which achieved savings of £183,000 – and 1 million kW – per year. We have also upgraded our factory’s gas boilers – some of which were more than 50 years old – with condensing boilers, and replaced gas heaters in the International Logistics Centre with infrared heaters.

“Meanwhile, in our R&D facility, we operate our air conditioning on a timer system to save energy, as well as turning off equipment overnight, where possible, when it is not being used. Additionally, we have installed multiple free-to-use electric car charging points across the site for our team members to use.

Impressive waste reduction

“But it’s not only energy consumption that we have been targeting.  Since 2013, we’ve significantly cut back on the waste produced at our ink factory, and last year (2021), 689.7 tonnes of waste produced on site went for recycling.

“Other initiatives include: 100% of our raw materials packaging is reused and recycled; we return 1000 litre IBCs for cleaning and reuse, rather than disposing of them; and a number of moulded components used as part of our ink pouches are made from recycled materials. Additionally, we now secure our pallets with straps rather than using shrink wrap, which reduces our waste by around 8 tonnes annually. We are also in the process of swapping plastic tape for paper tape.

“In R&D we have also achieved a 50% reduction in glass jar testing; a 38% reduction in end container testing for one litre bottles; a 74% reduction in end testing for five litre cubitainers; and we have cut back on the use of one, two and three litre pouches by 29%, 33% and 20% respectively. We are literally looking at every single part of our operation and making changes to reduce our environmental impact.

Smart cutbacks on solvents

“Overall, thanks to the printers we sell becoming more technologically advanced over the years, less ink is required during the printing process.  This is obviously a better and more sustainable situation in itself. However, you can’t print without ink – it’s the most crucial element of printing. So for the inks that we produce at our factory, previously we would typically use around 140,000 litres of oil-based solvents to clean the vessels used in our ink-making and mixing equipment.

“However, very recently we replaced our oil-based solvent cleaner with an 80% water-based (aqueous) cleaning solution, manufactured by a company called Safe Solvents. Coinciding with this, a first-of-its-kind pot washing machine, also supplied by Safe Solvents, was installed at the factory.

“Suitable for use with the new aqueous cleaning solution, the machine offers a significantly more efficient pot washing solution on our site. The aqueous cleaner and pot wash machine combo makes it possible for us to separate solvent and aqueous waste, and in the future, it could enable us to reuse the pots after they have been cleaned, and then when they are beyond reuse, have the clean plastic shredded and sent for further recycling.

Measuring and analysing is key

“The recently installed pot washing machine at Broadstairs is a world-first, so we look forward to reviewing our credentials in the future and seeing the difference it has made. The most important thing is that we continue to measure and analyse everything, as only by measuring can you improve.

“It really is a painstaking, but ultimately very rewarding process – we have achieved a great deal in the last 12 months with our renewed focus, but we are confident we can continue to make iterative improvements all over the site, across all areas of energy, waste and material reductions, to make this award-winning factory a world-class, sustainable one too.”

LED UV is the curing technology of the future, but so is conventional UV

Kevin Rhodes, Marketing Manager, Fujifilm WFIJ Systems, argues that conventional UV still has an important role to play in the future of wide format print.

LED UV curing technology is energy efficient, environmentally friendly, and extremely well suited to the production of a huge range of applications. It’s a massive area of R&D focus for Fujifilm and it is, quite rightly, seen as a key “technology of the future.” So far, so uncontroversial.

And yet, none of that means to say that conventional UV curing has – or will – become a “thing of the past”. Despite the obvious cost and environmental advantages of LED technology, there is no reason to believe that it will replace conventional UV altogether. It won’t. In fact, both technologies will continue to play valuable roles in the future of wide format print long into the future, and where conventional UV is the more appropriate solution, we at Fujifilm will continue to offer customers that option. This is something we’ve clearly demonstrated with the launch of the new Acuity Ultra R2 – which is available in either LED UV or conventional UV curing formats.

Pros and cons

LED UV does, of course, use far less energy than its conventional alternative. As LED UV lamps have a significantly lower level of applied voltage, LEDs have a lower radiance than conventional UV lamps. LEDs emit light in the visible part of the spectrum from 400 nm to 700 nm or in the near infrared (700 nm and 2000 nm), so only part of the spectral energy they emit is UV light. Because they use a fraction of the energy of conventional UV lamps, they don’t need to warm up or cool down, so they are immediately ready for use and don’t use energy unless they are operating.

Furthermore, LED UV lamp lifetimes are much longer than those of conventional UV lamps (approximately 10,000 working hours compared to 1000+ working hours). As a result, one of the main selling points of LED UV for customers is the fact that it is more environmentally friendly and that costs are lower. There is only one real downside: the lack of safe cure and adhesion of high ink deposits at speed, which for some printers is a substantial issue.

Understanding the relevant regulation

Another common reason cited for the inevitable decline of conventional UV is government regulation. But here, many of the regulations concerning conventional UV are widely misunderstood. The European Union’s Restriction on Hazardous Substances II (RoHS II) regulation bans the use of heavy metals, including lead, mercury and cadmium. As a result, domestic light bulbs that use conventional UV can no longer be purchased, having been replaced by LED UV. For this reason, many assume that conventional UV for business use is on a similar path to regulatory oblivion.

However, this regulation does not apply to larger printing equipment, which is typically classified as ‘large-scale stationary industrial tools” (LSSITs), so the UV dryer modules manufactured for them are exempt from the RoHs II directive. Through the development of UV technology and compliance with the manufacturer’s information on safe disposal, the use of medium-pressure UV lamps containing mercury within the printing industry is deemed safe. As a result, mercury is still widely used throughout the industry and there is no indication that this is likely to change.

Counting costs

The operating costs of LED UV are certainly lower than the costs involved with a conventional UV machine, where increased energy and consumables usage needs to be factored in. But if the extra speed and increased adhesion and block resistance of conventional UV allows a print business to produce more work, the additional business can more than cover all these costs, as well as funding responsible waste management systems to minimise environmental impact.

Heat and speed

Another common belief is that conventional UV cannot be used on heat-sensitive materials, but Fujifilm’s Acuity Ultra R2, for example, features a unique water-cooled vacuum table that allows rapid UV curing on a huge range of thin, heat-sensitive materials. The main benefit of conventional UV that cannot be matched by LED UV is the speed at which it is able to print. Depending on the user, this one benefit can outweigh many of the negatives, meaning that it’s often the option that makes the most sense for many businesses. As conventional UV undoubtedly dominates the market in terms of productivity, it remains the obvious option for printers producing high volumes with rapid turnaround times.

Conventional UV is best for high production, fast-turnaround print. LED UV offers environmental, cost, and energy saving benefits when speed is not as crucial.

Kevin Rhodes | Marketing Manager, Fujifilm WFIJ Systems

The choice is yours

LED UV, of course, has an extremely valuable role to play in the future of wide format print– and we’re very proud at Fujifilm of our extensive range of LED UV curing printers. But it is not a complete replacement for conventional UV. There is still very much a need for both types of technology, depending on the customer’s requirements. The two exist in tandem and will continue to do so. Conventional UV is best for high production, fast-turnaround print, while LED UV offers a multitude of environmental, cost, and energy saving benefits when speed is not as crucial. Until LED can match conventional UV’s performance, specifically its speed and depth of cure, it is unlikely to be a wholesale replacement for conventional UV.

Ultimately, it’s up to the customer to decide on the most appropriate solution for their business, and we will continue to offer them that choice.

Not just a pretty face

What does good product design really mean?

Following the announcement that Fujifilm’s new wide format printers, the Acuity Prime and Acuity Ultra R2, have won Red Dot Awards for product design, Fujifilm’s Kevin Jenner asks: What does good product design really mean? Beyond a stylish exterior, he argues, it’s about usability, reliability and value. Why would a tradesman buy a Mercedes Sprinter van and fill it with Makita tools? There are cheaper vans and there are cheaper tools, but in those brands he’s buying into a perception of quality and reliability that is going to enhance the work that he does and boost his business.

The cynic might say that brand perception is down to good marketing – and they may well be partly right – but brands that stand the test of time, brands that people have confidence in and keep returning to, time and again, have a lot more than clever marketing behind them. They have outstanding product design.

In our own industry, businesses make important, and often very capital-intensive, buying decisions all the time. Machines reach end of life and need to be replaced, and business owners weigh up what their customers want against what is needed to deliver it, and then they make a choice. Cost is a major consideration in these decisions, of course, but more than that, people are asking “what can it do, how well can it do it, and how easy is it to work with?”

If a CapEx investment can expand the customer offering, boost productivity, cut waste, save time and reduce hassle – that’s good design on the part of the manufacturer, and a solid investment for the customer. But how do we get there? How do we create extraordinary design that can transform a business by making work more efficient, more enjoyable, more productive and ultimately boost ROI?

“The broader one’s understanding of the human experience, the better design we will have.” That’s Steve Jobs again. Good design starts with understanding. By seeking to understand everything, from the long-term business goals, to the day-to-day frustrations of the customers we serve – we give ourselves the best starting point for good product design.

So for this project we needed a deep understanding of our customers’ needs and time to have meaningful conversations with them. This wasn’t a box-ticking survey sent out by email, this was our designers (a specialist industrial design agency, Realise Design, appointed to support the Tokyo Design Team) shadowing our customers as they worked, looking for a thousand small ways to optimise their experiences and their businesses.

We looked at how improved product design could lead to improved usability, to enhanced performance and to better ROI. I’m going to quote Steve Jobs once more (last time, I promise!) as I begin to wrap this up.

Simple can be harder than complex. You have to work hard to get your thinking clean to make it simple.

Steve Jobs | Formerly Apple

Products which are developments to a design first conceived a decade ago sometimes need a complete rethink, in effect going ‘back to the drawing board’. But not at all in the sense that the old is completely discarded, more in the sense that everything is scrutinised and nothing stays as it is simply because ‘that’s the way it’s always been’.

With this project, we gave ourselves the freedom to go right back to first principles, and that led us to create something quite different to anything either we – or anyone else – had created before. This is the reason that when we first revealed the new machines in June 2021, we called them ‘the new blueprint for wide format’.

 

As with any product, the default is always to adapt what is there already, and products which have been tinkered with, tweaked and adapted over the years can often develop layers of complexity which are detrimental to performance, but we’re so used to them being there, it can be difficult to comprehend it being any other way.

Clever marketing? We’d like to think so, yes! But it’s a lot more than that. These products are designed to be a joy to work with; products designed for maximum productivity and versatility; products designed to be affordable. And that last point is important, the sleekest look and the highest level of performance is of no real value if it’s unaffordable to the people it’s designed for. A crucial part of good design in any commercial context is stripping out unnecessary costs while ensuring no compromise on what it needs to do well.

That was another critical part of the process we went through – we sought out the best component parts and the most suitable manufacturing partners to deliver on quality, performance and value. The end result, in our case, is a new range designed to redefine the price/performance ratio, deliver unrivalled levels of versatility and value and to boost ROI.

And we made sure they looked great too!

The new blueprint for wide format

From the place where it all began, comes a new blueprint for wide format

Read the article

Reading time: 8 minutes

The Fujifilm name has been closely associated with UV inkjet technology since 2005 – the year in which Fujifilm acquired the pioneering UV inks and inkjet company, Sericol, based in the seaside town of Broadstairs in Kent. Founded in 1950, Sericol had long been a screen inks pioneer and market leader. Then, in the 1970s, it launched the world’s first instant curing UV screen inks and built on this experience to commercialise the first UV digital inkjet systems and inks in the world in 1999. The immediate and rapid growth in this new sector resulted in Sericol being presented with a Queens Award for Enterprise in 2004 for its role in developing and commercialising these new UV inkjet systems.

With the Fujifilm acquisition in 2005, forming what is now known as Fujifilm Speciality Ink Systems, the company has gone on to produce some of the most highly regarded UV cured inkjet inks and systems on the market, including the popular Acuity range of wide format printers launched in 2007, and now with more than 1,800 global installations. This 20 years of experience means Fujifilm has developed a keen sense of what the market really needs, and perhaps more importantly, how it is likely to change in the future.

Market maturity

The early years of wide format UV inkjet development were largely defined by advances in technology that delivered rapid and continual increases in print speed and quality. In 2018, however, Fujifilm recognised that the market had reached an advanced degree of maturity, and a point at which a very high level of quality and productivity was assumed. New product launches were tending to offer only very marginal improvements in print speed and quality. In addition, Fujifilm also became aware that there was an opportunity to use these evolving technologies to drive improvements in wide format print ROI.

The market had reached a tipping point – a point at which more of the same, with minor improvements, was no longer enough. The market needed something fundamentally new. So, three years ago, Fujifilm made a strategic decision to start the process of rethinking its Acuity wide format offering; focusing on new  ways to deliver improved value, versatility and ease of use and in particular on defining a new level of print ROI. Fujifilm set out to do what it had first done back in 2000: to create a new blueprint for wide format.

Back to first principles

In terms of printing hardware and systems, Fujifilm has always been a technology company first and foremost, rather than a manufacturer, working with a range of OEM partners and other specialists to provide the best possible platforms for its inkjet technology. The Acuity range already has a deserved reputation for quality and reliability, but for this next chapter in the Acuity story, Fujifilm wanted a new level of design influence and control in order to take full advantage of what was possible, to create something that offered far more than mere marginal improvements.

To do this, the Fujifilm team returned to first principles, starting with an almost blank canvas and a challenge to strip everything back and create a completely new and improved range of machines. To help with this process, they brought in an award-winning industrial design company and tasked them not simply with making changes to what had gone before, but with completely rethinking the press design to maximise the value, productivity, ease of use and – most importantly – the ROI.

Fujifilm’s vision was to combine stunning aesthetics with exceptional functionality. In order to achieve this, the first step was to carry out wide ranging research, so the two companies embarked on an extensive and intensive listening exercise, meeting not only with business owners and directors, but also with press operators who had experience of working not only with Fujifilm machines, but others too.

This exercise produced an understanding of what worked, what didn’t, and what changes (whether simple or radical) would improve the value, versatility, usability, productivity and ROI, while retaining an eye for the environment in terms of reducing waste an making for a safer and more contented workplace.

It was clear from this exercise that the owners and directors of these companies want equipment that’s reliable, fast and able to give them a rapid return on investment, but being in a creative industry, they also want machines that look stylish and that are easy to work with. For press operators, it was also clear that good machine design – aside from the obvious benefits to productivity – can be the difference between job satisfaction and great frustration, and the listening exercise uncovered many aspects of machine design that could be improved upon.

Fujifilm combined the findings from this extensive research exercise with its own knowledge and inkjet expertise to provide a structure for the design process. In parallel, the team also carried out comprehensive research into the best components and technologies on the market, and the best routes to assembly and manufacture. The output from all this research and creative thinking was effectively a completely new blueprint for what a UV inkjet system of the future should look like, how it should perform, and how it could be brought to life.

Bringing it all together

Four design criteria emerged from the blueprint that informed all design choices and helped to identify the right manufacturers and suppliers to work with, as well as the OEM partners to help to bring it all together. These were: quality, value, performance and ease of use. In addition, every component part selected was chosen with these four criteria in mind, from the printheads to the user interface, lamps, static control and vacuum solutions. In all cases, Fujifilm made choices based on answering questions like: “does it do what it needs to do?” or “could it be done better?” Nothing was left unchanged that could be improved.

Three years on, the result of this blueprint is the all new Acuity range, designed and developed by Fujifilm. First and foremost, this new Acuity range has been designed to redefine the price / performance and ROI that can be expected from a UV inkjet system. This has been achieved through careful design choices, stripping back features that don’t add value, and maximising quality, value and performance where it matters most. The result is a high performance range available at a competitive price with low cost in use, a combination that radically changes print ROI.

The new Acuity range is also built for printers from the ground up, resetting expectations around operational ease of use. The ‘question everything’ approach to the whole process has allowed Fujifilm to put the operator experience front and centre. “We’ve taken on board the frustrations and inconveniences identified in our extensive market research, and addressed those concerns to create a range that is a real joy to work with and operate, with the additional benefit of maximising uptime and productivity,” says Kevin Jenner, European Marketing Manager, Fujifilm Wide format Inkjet Systems.

The first two printers made to this new blueprint are the Acuity Ultra R2 and the Acuity Prime. The Acuity Ultra R2 is a completely redesigned version of the Acuity Ultra, which itself had set a new standard for superwide print when it was launched in 2018. The Acuity Prime is an entirely new, mid-range flatbed which offers ease of use and print ROI unmatched by anything else on the market.

For more than 10 years since its initial launch, the Acuity range has built a reputation for quality, versatility and value and this new range will enhance the Acuity brand on all those fronts, while maintaining the reliability standards that have always been the hallmark of Fujifilm’s inkjet systems. And of course, the new printers take advantage of Fujifilm’s renowned UV inkjet ink.
