Why PUR adhesive is better than EVA adhesive for book binding?

There are a number of binding options, including Polyurethane Reactive (PUR), Ethylene Vinyl Acetate (EVA) hotmelt and Polyvinyl Acetate (PVA) cold emulsion adhesives, or Smythe sewing. PUR has only been in bookbinding since about 1989. PUR binding was first adapted by midsize trade binderies for producing many trade journals and annual reports due to short lead times using highly coated and cross-grained papers without sewing. These markets will continue to be the high users of PUR, but publishers are now recognising the benefits of PUR and are requesting the use of PUR binding to ensure quality and longevity to their products.

Why PUR?

Since its introduction, PUR use has increased dramatically. PUR is chosen over standard hotmelt adhesives for many reasons, the most important of which are its superior adhesion and the ability of a PUR-bound book to lie flat when open.

It is very important to understand the main differences of the two important binding technologies in the market today.

Different types of Glue

 

Advantages of PUR

1) Excellent flexibility and lay-flat quality.

2) Cold and heat resistance enabling books to be bound, stored and used in extremes of temperature.

3) PUR can bind varnished, UV-coated, carton, mylar and other stocks.

4) Impervious to print oils used in the digital print process and binding quality is unaffected by ink migration into the spine.

5) 40% to 60% better page pull results as compared to EVA Hotmelt.

6) Can handle recycled papers.

7) Handles cross-grained stocks better.

8) Square backbone: Because only a small amount of PUR needs to be used for binding, less adhesive is squeezed out when the cover station and side clinchers attach the cover and form the back.

9) PUR is also environmentally friendly due to its low VOC (Volatile Organic Compounds) and the working temperature is set at around 120°C while EVA is at around 170°C.

Advantages of EVA

1) Fast curing (in few seconds) & Quick turn-around time.

2) It is cheaper when compared to PUR glue.

3) Ease of operation, most often it is very easy to handle and maintain PUR gluing system as compared to Hotmelt gluing system.

4) Finished book can be easily handled.

5) Cleaning process of EVA binders is very simple/easy as compared to PUR binders. Most often it takes more time to clean PUR binders.

4) EVA Hotmelt glue still have their place in book-binding, especially when it comes to binding thread-sewn books, as the thicker glue allows for greater penetration into the spine area of the folded sections.

BOOK

In summary, both processes are still widely used within print finishing. The question’ which is best’, probably needs to be replaced with the question ‘which is most suitable’, as the decision to use one over the other is very much job specific and would involve numerous considerations – from substrate used and thickness of the book, to the intended use of the product and any financial constraints to produce.

Duplo International’s Success Story

I’m now approaching my 24th anniversary with Duplo International Ltd, having joined the business in June 1988. I’m rather proud to have been part of the team that has helped grow the business nearly ten-fold in that time.


The success of the business is due to the marriage of cutting edge product innovation & manufacturing, combined with first class sales & distribution. Duplo Corporation in Japan maintains a high level of innovation, producing products that meet the changing demands of our customers, those organisations producing printed products for their customers. Innovation is based on their possession of long and established work in this specialised field. Duplo have been tremendously successful in developing products that meet the needs of the ever changing digital print market. http://www.duplonet.co.jp/eng/welcome/

Over the past 25 years, Duplo International Ltd has developed an extensive distribution network, starting from its base in the UK, and then developing via distributors across the old European Common Market during the 1980’s, followed in the 1990’s by developing new relationships with the Eastern European countries after the fall of the Berlin Wall and exploring opportunities arising in Africa & the Middle East. We now have a network of distributors stretching across 70 countries. Looking back, the world seems a much smaller place than it was in the 1980’s!


People are a big part of our success and we have always been careful to recruit talented multi-lingual people from across all our territories. This ensures we have the best understanding of local markets and the needs of our customers. By investing in people with a broad range of talents in sales, marketing & engineering, we ensure the best possible support for our products and customers.

Financial stability & strength are an important element in a successful business. By re-investing in the business we have ensured we have the financial stability to carry stocks of product, available for immediate delivery to the network of distributors across our region. Financial stability also enables us to keep pushing into new markets, both in geographical terms and in the range of products we stock & distribute.

For any business, it is important to keep exploring the opportunities for growth. I believe we provide our customers with this same opportunity by supplying them with innovative products, allowing them to provide new services to their client base. Allied to our after sales service, investment in a Duplo machine is an investment for the future growth of a business.

Many years ago there was popular business adage ‘no one ever got fired for buying IBM’ such was the reputation of IBM for quality, innovation and support. Even today, in these difficult economic times, IBM continues to outperform the rest of the IT sector due.
Duplo aspires to the same reputation in the print industry. In troubled economic times, investing in a Duplo product is a great way for our customers to gain a competitive advantage.

Trends in the Print Industry

To say the print industry is changing is an euphemism. Today when you say printer people think that you are referring to the little device that sits on their desk at home or in the office that produces beautiful photo quality colour. This is one of the benefits of improving technology. It also means that putting an image on paper can be done by just about anybody easily at the click of a couple of buttons. Of course this is one of the reasons why Kodak is no longer the high flying company that it once was. Digital photography made taking pictures easy, printing them and putting them into a pretty album has become easy too.

As technology makes processes easier adding value for customers becomes more challenging. Add to that the worst recession known to mankind and you have the perfect recipe for major change in industry. The production of paper for print has dropped by 30% over the last 4 years. The Print business’s problems were caused largely by not understanding the internet and its associated revolution of computing and communications, and not adapting to a different collection of marketplaces and decision-makers with new needs and new agendas.

 What will happen next? Doing nothing is only an option if you want to go the way of the Dodo. Getting creative with print, and lets face it most people can’t tell how it has been printed these days and they don’t really care as long as it looks good, means that finishing will be where you add value.

Deskilling of the labour force, especially in print, has meant that manufacturers have all had to make machines that are easy to use. I’m happy to say that Duplo have been at the forefront of this drive. Drupa 1995 was when they launched the world’s first self-setting stitcher folder, which could change size fully automatically in less than 60 seconds and was accurate to within 0.2mm. Technology has moved on, especially with the advent of the print run of one. No wastage on set up and fast changeover are a given. More complex tasks are now done without the need for operator intervention. Cutting, slitting and creasing all in one pass, fully automatic set-up from a barcode on the sheet and with image shift recognition. What is more you can integrate folding and skip perfing all in one pass and with zero operator intervention.

Why is this good? Finishing is where you can add value to your image, and when it is your digital press operator doing the finishing as well, you’re adding value at no extra cost. Not convinced? Imagine receiving 25 business cards on an SRA3 sheet and told to cut them yourself?  A print that isn’t finished is virtually worthless! And when all Printers have understood this they might stop paying premium prices for the easy bit: printing.

TWITTER: MY FIRST THOUGHTS

Am I a Twit?

This was my conundrum – am I being a Twit to enter the world of twitter, or am I a Twit to avoid the whole area of social media?

Would it be another drain on my time, as I grapple with all the new contacts and scratch my head to create catchy messages, or will it open up a whole new valuable resource?

Being somewhat old school, I was also concerned about security – could someone steal my identity and what about legal issues? Would I fall foul of the law inadvertently?

In the end I decided if it was good enough for the BBC and far more eminent people to use, it must be something to at least try for myself.

A colleague showed me how to find the Twitter site and l logged in my details. Next I had to find five other Twitter accounts to start me off. It was as easy as that. Now I have to start the creative part and this article is my first step to try and help others who might have felt as I did. So if you would like to share your thoughts and business experiences with me we can set forth and begin our journey together.

From a new Twitter recruit.

THE IMPORTANCE OF EVENTS AND EXHIBITIONS IN THE PRINT INDUSTRY

With Drupa 2012, the Print ‘Olympic ‘event coming up in a few months I thought it would be a good idea to analyse the  role of ‘Events’ within the print industry in this multi-media world of today.

First I would like to clarify what I mean by ‘Events’. Effectively I am thinking about exhibitions like IPEX and Drupa plus manufacturer led events including open houses in showrooms and focussed events in outside venues.

Events /Exhibitions have changed dramatically since I first started to tread the floors in the NEC and Dusseldorf Messe. Customers can now access information on products and services very easily via the web. No longer do they visit exhibitions on a ‘fact finding’ tour picking up hundreds of brochures.

Typically customers know what type of product or service they want and they have narrowed their choice down to 2 or 3 options and are coming for final verification. Or they have seen something interesting, say a new technology, in the printing press and come along to see it for themselves.

So exhibitions have changed. Basically people who are either in the buying cycle or are looking what is coming to plan their future strategy come to events. Let’s be honest everyone is too busy just to pop along anymore just because.

At Duplo we focus on one thing when we plan events. Making sure that our potential customers know what we are showing and talking about. Our customers can then make an informed decision if they need to attend. This is why for our latest open house (titled ‘The Event’ by chance) like our London Calling annual event we use extensive PR, prominent outside back page advertising, direct mail, email blasts and most importantly sale managers visits to inform our customers what we are doing.

So are Events important? In a word YES! I still have not yet met a printer who has bought a piece of hardware who has not wanted to see it first, test it, run jobs on it and most importantly meet the organisation who will service the machine afterwards. I think I have a few mores miles to tread in exhibition halls.

IS IT NECESSARY FOR COMPANIES IN THE PRINT INDUSTRY TO ADOPT SOCIAL MEDIA?

Duplo International is the world leader in print finishing. It has over 40 years of experience in bookletmaking and print finishing related products. Automated precision, innovation and superior quality are at the heart of all Duplo products. In the past Duplo International was quite traditional in its approach towards communication. We mainly used three mediums to distribute our content:

1)      Email

2)      Marketing Resource Centre

3)      Website

Our content comprised of product brochures, videos, case studies, product packs, product bulletins and press releases to mention a few. We were using a passive approach that is asking our customers to come to us if they need any information about our products. It was a one way communication but in some cases feedback was possible from the receiver of our content. We agree that we never had a marketing budget of certain blue chip companies but still we were successful in positioning our brand to be the most trusted brand in the print finishing industry.

Social media was once the exclusive roaming ground of teenagers, but not anymore. As Twitter and LinkedIn have taken off with astounding success in the business arena. We at Duplo International have revised our communication strategy to exploit these new tools. Now, we will be actively using 7 channels to distribute our content:

4)      Twitter

5)      LinkedIn

6)      YouTube

7)      Blogs

These channels will help us to distribute the content to the place where our target audience is. It will also open up new avenues for us such as brand awareness, lead generation and customer service and engagement to mention a few. In today’s context the role of International Product Marketing Director has changed, no longer is it about being responsible in the development of new products and markets but now also to fill the sales pipeline. Social media will truly change the way we are communicating with our customers and prospects.  We are totally convinced that developing a social media presence will open up a whole new set of tools for driving your customers to turn their print into more than just a paper.

We are taking this step to build our future and we invite all of you to join us. Let’s make a better and stronger community.

Kind regards,

Bruno Picquet
