Advantages of Roll-Fed Digital Printing – Domino N610i

tempo-as-murat-papila-dominMurat Papila: “Domino N610i is a production tool that fits and suits the job structure of today’s requirement asked by brand-owners. With N610i the user gets a production tool that combines the speed and productivity of conventional press with the flexibility of a digital press.”

Tempo Inc., has been representing Domino Printing Sciences Plc in Turkey for more than 30 years. As a company active in 120 countries, Domino Printing Sciences develops coding and printing technologies. Founded in 1978, the solutions of the company based on inkjet technology are offered to Turkish market through Tempo Inc. We’ve discussed with Murat Papila,who is the Sales and Marketing Director of Digital Department in Tempo Inc, the latest digital printing system N610i:

matbaa&teknik: What are the job opportunities that this technology will offer the print houses (offset print houses) ?

Murat Papila: Label printers will have the opportunity to deliver in smaller batches. This reduces the risk of having outdated stock at the brand-owners.

As regulations and other changes can be easily adapted with digital technology the amount of pre-printed labels of the same version can be reduced without getting into cost problem.

With this the label printer gets into a position of being service provider with logistical responsibilities.

The brand-owner is crying for the right label, in the right language, the right version and in the right quantity delivered on time. No Stock keeping, please!

This are chances for labels printers to differentiate from others.

 

matbaa&teknik: What are the differences between sheet feet digital press to roll feed digital press ?   

Murat Papila: There is little digital technology difference besides media throughput and print widths associated that are required.

On a narrow web digital roll fed system there are typically less print heads that need to stitch across the width and print speeds are traditionally higher.

Although cut sheet paper is effective for many applications, there is a limitation on throughput speed during the printing process.

Cut sheet devices are not as effective to handle large volume demands.  For these types of jobs, roll-fed printers are significantly more productive and offer greater cost effectiveness.

 

matbaa&teknik: What are the job opportunities for the roll-fed digital press ? Please also do mention application details and/or success stories.

Murat Papila: The label market is changing. From traditionally long job orders produced on conventional printing presses, today there is increasing demand to produce shorter job lengths.

Driven by marketing initiatives, brand differentiation leads to increase in SKU’s and short turnaround time.

Conventional analogue printing technology that comes with longer job setup time is not economical to deliver these short job runs.

Printing these short jobs digitally reduces turnaround time, inventories and hence cost.

Current installed analogue presses have been purchased as production tools years ago to suit to the job structure at that time.

But the job structure has changed a lot (many more jobs with shorter run length and different jobs variations). Consequently the current installed production tools do not fit any longer to the new job structure demand.

Domino N610i is a production tool that fits and suits the job structure of today’s requirement asked by brand-owners. With N610i the user gets a production tool that combines the speed and productivity of conventional press with the flexibility of a digital press.

A roll-fed digital press can be combined in-line with conventional finishing tools. This allows to use the same hot-foil or cold-foil plate and the same die-cut pattern and still print a variety of versions of the same job without stopping the press.

At the end there is a big role of different versions (SKUs) already finished and die-cut. Adding a turret reminder inline would even allow to produce micro rolls to be delivered directly to the label-applicator. And all this without stopping the press or the finishing line.

It is proven in installations that UV inkjet digital print can be combined with hybrid analogue print steps. E.g. UV-Inkjet ink on top of Flexo-White. Or cold foil on top or underneath of inkjet ink. Doing so it is possible to use metallic foiling on clear/transparent media and simulating every metallic colour by printing with UV-Inkjet on top of the metallic silver foil.

UV-Inkjet is very robust against scratch, humidity and aggressive fluids. In most cases there is no need to add a protection varnish or layer.

 

matbaa&teknik: What kind of printing technology is being used for roll-feed digital presses ?

Murat Papila: There are different technologies used in digital narrow web printing technology, from magnetic or laser toner (liquid / dry) fusion to continuous, thermal and Piezo InkJet.

The latest digital presses typically apply UV inkjet technology based on Piezo inkjet technology, allowing for high resolution printing with print speeds up to 75m/min.

 

matbaa&teknik: Do you need prime coating before printing ? Are there any pre press treatment needed ?

Murat Papila: Domino N601i can print on most media that is used by our customers in their flexographic web presses – there is no need for priming.

As for all digital printers, there are guidelines specific to the type of digital press as to how the artwork is provided. There is little difference with the pre-press design for CTP.

The Domino N610i is driven by Esko, which is used by the majority of label printers and the pre-press output can be directed directly to the digital RIP as if it were in a CTP process.

 

matbaa&teknik: What do you think about  the print quality ?

Murat Papila: The Domino N610i delivers the highest print quality available at 600 by 600dpi, delivering a vibrant gamut in CMYK.

Print quality should be observed in colour vignettes, flat colours areas, small text and opacity of white.

The Domino print quality is produced at the standard speed of 50m/min independent form the number of colours. 4 -7 colour print all with 50m/min.

matbaa&teknik: Can you compare the cost for the long run jobs to short run jobs ?

Murat Papila: As always the key question is about definitions: what is short run and what is long run?

From label printers we know that 80-90% of all jobs in Europe are below a specific run-length of .e.g 3-4.000lm. Those jobs are suitable to be transferred to the Domino press from the costs point of view.

Current customer installations are converting more and more jobs from conventional to flexo and letter presses to the Domino press.

Although the cost per piece may be higher using a digital narrow web press, reduction of inventory, stock and waste makes the digital narrow web press economically sound for short to medium runs.

Also long job runs with different versions of the same product are a good match for the digital press, as no plate change and setup for the individual version is required.

There is no difference in the cost per square meter output for the same label version in a short or longer job run, but the costs related to cleaning and services apportioned to the job makes the difference – these are clearly less on a short job run.

 

matbaa&teknik: What are the advantages of your roll-fed digital press compare to it’s competitors ?

Murat Papila: Domino offers a modular hybrid production tool. In difference to competitor systems Dominos unwinder, print tower and rewinder are modular stations and are positions next to each other without being physically connected. This allow to add other devices e.g. inspection systems between print tower and rewinder, or are at later stage have a flexo station between the unwinder and the print tower. A maximum of modularity is offered with the in-line / off-line capabilities. Customers can chose to do a job with in-line finishing and working offline for the next job.

Another big difference is the productivity. Domino is the only UV-Inkjet label press offering 7 colour printing at 75m/min with very good quality.

The Domino N610i delivers the highest native print resolution available with 600 by 600dpi with the highest opacity white available.

Domino’s unique I-tech technologies deliver maximum press uptime and reliability. The i-tech feature “Clean-Cap” for example offers automatic cleaning of inkjet heads without the need for operator intervention, delivering consistent print quality from job to job.

Add to this the fastest net throughput available delivering 3.000-4.500 linear meters of print

Another big advantage is the capability to handle large roll up to 1.000mm diameter. This means less roll changes and consequently a higher update for the press.

 

matbaa&teknik: What are your perspectives and expectations or the Turkish Market ?

Murat Papila: Also in Turkey we see a growing demand on label printers for short turnaround of smaller jobs leading to a demand for digital full colour label solutions.

Compared to more ‘mature’ label markets the cost for supply of labels, specifically to the Turkish national market, seems more price sensitive and still often is a barrier for investment. It is expected that the increase in demand from brand owners on the label printers will turn around the price issue and that investments in digital presses will grow.
