Precision Printing to Add Third LED-UV Press

RMGT928P mid

Following its investment in two RMGT Ryobi Series 9 LED-UV presses last year, The Precision Printing Company Ltd, Barking, the multi-award winning business offering creative print solutions produced with state-of-the-art technology, has announced an order for a third machine: a second eight-colour perfector, to be installed in its new Thames Gateway factory.

The August / September move – just two miles from its existing site – will expand the business from 3,500 square meters to 5,000 square meters. The new Ryobi 928P SRA1 LED-UV sheet-fed machine will be installed at the new site to provide for business continuity whilst existing equipment is moved.

The machine ordered is similar to the existing perfector: an eight-colour convertible perfecting press for 8-up A4 format print production. Two LED-UV curing units are incorporated into this configuration – one situated over the perfecting device and the other at the delivery end of the machine, enabling one-pass instant curing perfecting. The press will also be equipped with Smart-RPC fully automatic simultaneous plate changing, dramatically reducing make-ready times for job changes.

This will also be the first press in the UK to be fitted with the new PQS-D colour control and inspection system. Shown for the first time in Europe at Drupa, and utilising inline CCTV camera technology, the PQS-D inline printing quality control enables the operator to monitor printing quality on both sides of the printed sheet in terms of both colour density and comparison to the pass sheet.

If a defect, such as a hickey, is identified, the operator is alerted on the control panel via a visual display and warning tone. A tab is inserted into the delivery stack until the defect is cleared, when a further tab is inserted.

The initial perfector was supported by a Ryobi 925 – a five-colour straight press also equipped with LED-UV curing and an inline spectrophotometer. Plates for the two presses were provided by two Cron CtP systems, all purchased from Apex Digital Graphics, Hemel Hempstead.

The two Cron 36-64GX UV-P units offer a combined capability of producing over 80 SRA1 plates per hour. The systems have been imaging onto Cron’s Blackwood UV plates.

Group Chief Operating Officer of Precision Printing, Andy Skarpellis, commenting on the latest press order, said: “The Ryobi / Apex relationship has gone from strength-to-strength and the market we are now pursuing allows us to produce uncoated work same day into London which was unachievable with conventional machines. It mirrors our digital platform beautifully and allows us to utilise the cross platform much closer than before.”

Adding further comment about the investment in LED-UV equipment, Chief Executive Officer, Gary Peeling, said: “It has revitalised the litho side of the business. It gives us the immediacy and simplicity of operation that we get from digital.

“If we are going to have a successful offset business we won’t do it by doing the same thing we have done for the last twenty years, so we are going new and modern and looking forward to the opportunities greatly.

“We are working hard to make using more printing simple for our customers. LED-UV allows us to produce wonderful looking results on uncoated substrates, which are increasingly popular. To compete, printing needs to be fast and simple. It is often the difference between printing or not from the customer perspective. This modern press technology allows that.”

Trade Printing

When talking about the work being produced on the RMGT equipment Andy Skarpellis referenced both hybrid digital/litho work and the trade work generated by the company’s WhereTheTradeBuys.co.uk website: “The output quality of the Ryobi machines is excellent of course, and with the LED-UV feature we can produce a finish to match our Indigo digital output, allowing us to produce combination litho/digital print products for customers. This means that we can combine personalised sections within long run publications at an economical price.

“For our trade printing business, the new presses mean that we are able to offer same day delivery for volume offset print orders into London, or overnight delivery, even if they are produced on uncoated stock – something that we could only do with short run digital requirements before.”

Gary Peeling added: “Our London location is an advantage in supporting the capital, but it comes at a cost – a problem that Tokyo printers share! These presses are compact and the UV drying also removes all “work in progress” from the shopfloor. We could print 500 runs and deliver today digitally; now we can offer 50,000 as well.”

Commenting on the order for Apex Digital Graphics, Neil Handforth, Sales & Marketing Director for the company, said: “This is a very significant order for Apex and for RMGT because it has come from such a high profile and well respected print business as Precision Printing. It is a great testimony to the performance of the eight- and five-colour presses, which have shown to be a powerful litho package for the work being produced by the company. Having proved to themselves that LED-UV is a game changer for litho production, we are more than delighted to make preparations for a third RMGT machine to be installed.”

Press Detail

RMGT’s increasingly popular 920 Series features a maximum paper size of 920 x 640 mm, enabling the eight-up printing of A4 size pages, as well as A1 size posters. The versatility of the press extends to stock thickness, with the 920 Series being capable of handling paper ranging from 0.04 mm onion-skin to heavy 0.6 mm card stock.

The LED-UV curing system was pioneered by Ryobi, with the company unveiling its first such product at Drupa in 2008. Developments in ink technology and manufacture have now caught up with the huge potential offered by LED-based UV drying equipment. LED-UV ink is now available from a host of major ink suppliers. This year is seeing a growing commercial acceptance of LED-UV in the UK, where it will follow Japan and a number of European countries. The environmental benefits of the technology and the significant cost savings through reduced power consumption are the two outstanding benefits of the equipment. Adding LED-UV also eliminates the need for powder spray, and removes ozone from the process, with the required ducting for extraction – another significant cost element. The stunning productivity and quality of the technique are self-evident when the system is viewed in action.

Flexpress Invests in RMGT LED-UV Technology

In Offset Presses on April 6, 2016 at 10:17 am

Leicester-based Flexpress Ltd has detailed its installation of two new Ryobi presses, both equipped with the latest LED-UV curing technology. The B3-format 524GX press with LED-UV replaced a similar format 524GX, whilst the SRA1-format 924 with LED-UV replaced a B2-format Ryobi machine, with the increase in sheet size allowing the business to handle an even wider range of work.

The products were supplied and installed by Apex Digital Graphics, Hemel Hempstead, the official RMGT (Ryobi) representative in the UK for presses up to SRA1 format, and the exclusive CtP and plate distributor for the Chinese pre-press manufacturer CRON for both UK and Ireland, and a company that has enjoyed a near 20-year relationship as an equipment supplier to Flexpress.

Commenting on this latest investment, Flexpress Managing Director Steve Wenlock said: “The big benefit of LED-UV for our business is the fact that the drying is instant. We work from a fairly small unit and therefore we can’t really afford stacks of paper sitting around the floor for too long, so the idea is that we can turn jobs around quicker, be even more responsive to our customers need, get the paper out of the door faster, and to an even higher quality than before is something that should positively delight our customers.

“From a customer angle, time is the number one advantage,” Steve explains. “No customer says I’m going to give you more time to produce this job! Speed of turnaround is ever more critical: LED-UV technology will allow us to move work quickly on to the next stage of production, whether that is backing-up or finishing the job for delivery.”

The new presses join a recently installed Cron computer-to-plate device, also supplied by Apex, ensuring a cost effective production system from plate production through to finished job. The 36-inch UV platesetter is able to image and process UV metal plates for Flexpress’s SRA1 and B3 printing equipment.

“Quality is the other important aspect: because sheets exit the machine dry, set-off issues are eliminated – something that can occur all too easily if a job is being rushed through, even in a company that is focused on quality production, especially when working with uncoated stock. The process also means that there is no absorption of ink into the stock, which means less ink is used as well as faster drying.

“The instant drying offered by LED-UV also means that we can consider printing on a wider range of substrates, such as plastics. We do produce such work already through our Indigo press, but higher volumes of such work will be significantly more cost effective to produce on a litho press. We believe that there is a growing market for this type of work.”

Why RMGT / Ryobi?

Commenting on the choice of presses for this latest investment, Steve Wenlock references Ryobi’s pioneering role with the technology: the company first exhibited the potential of LED-UV back at the Drupa show of 2008. The company has continued to develop and refine the technology since then, whilst both ink suppliers and the press competition have been playing catch-up.

“We have worked with Apex and Ryobi for nearly 20 years. We know Ryobi as a leading press manufacturer and Apex as a supplier that really supports its customers. Ryobi are undoubted leaders in this technology, so why would we need to look elsewhere? Our operators know the Ryobi architecture and technology already, so it is just a matter of adding the LED-UV knowledge on top of the extensive printing knowledge that they already have.”

Inking Up The Press

All of the leading ink suppliers now offer product for the LED-UV market, and all are working hard to establish their product as the ink of choice.

“We are working closely with Toyo inks,” said Steve Wenlock. “They seem very focused on providing quality products backed with good service. They have outlined workshops and training for our press operators. They are a supplier that is keen to invest in LED-UV.”

Inks for the process are referred to as “duct stable” inks, meaning that there is no need to wash up at the end of the day or re-ink first thing in the morning – a real time saver, and something that will win the hearts of press operators for sure!

The Cost Equation

According to Steve the cost equation is likely to be different for each print company. A range of factors will need to be considered. For those already using existing UV solutions, the electricity costs for LED-UV will be a huge winner, but for those entering UV printing for the first time, the savings on production speed may well be the deciding factor. Yes, ink costs will be higher, but with no need for spray powder or seals, the savings on such consumables can help offset these increases, along with the fact that drying is no longer relying on a degree of absorption of ink into the printed stock, meaning that less ink will be used on each job.

The performance of LED-UV technology on a litho press brings the process much closer to digital production in many ways, but with the creation of the best possible print quality and stock flexibility. Printers seeking to invest in litho equipment need to seriously examine the benefits offered by LED-UV in great detail before finalising their decision.
