From Volker Haske - Branded companies and retailers alike expect an ever-increasing print quality for their film packaging. Simultaneously, decreasing order sizes and continuous cost pressure challenge manufacturers and converters to find or combine respectively printing technologies, which are suitable and effective for them.
The paper is a field report from the point of view of a flexoprinter, who has successfully implemented rotogravure as a complementary printing process. The paper will point out the reasons for this decision and also illustrate the process as to how to select from the available machine concepts and technologies respectively (e.g. sleeve system). In doing so, both, rotogravure and flexographic printing will be compared to each other from the point of view of a printer.

From Dirk Schibull - Basically has the packaging gravure printing a very complex and demanding requirement profile. Specific ink systems and substrates require in the context of compliance with all relevant packaging features a comprehensive know-how. On this basis and in light of the general market trend with the tren... [Show more]d of steadily increasing pressure quality standards at the same time reducing lot sizes is a key success factor lies in the cross-vendor standardization of processes. The standardization of concepts should include all the essential printing process parameters and variables: • Design system and reproduction • printing form configuration • Color Management • Color System • printing process The potential of a successful standardization are to increase the basic security system, the possibility of increased efficiency, and not least in increasing customer satisfaction

From Adolf Ahrens - Over the last years the order sizes of the food packaging sector became smaller and smaller. Even if food consumption in Central Europe stayed nearly constantly more and more private and regional labels or premium, bio and wellness brands are taking over the shelves, especially in the chilled sector... [Show more] of processed meats and cheeses. The result is a split of total quantities within the segments which causes a drastic reduction of lot sizes. To gear up for this situation is a hard challenge – especially for gravure printing. The prepress as well as the printing production including their technical equipment were conceived for high circulations. With a consequent standardisation of the processes of their in house repro department and cylinder production and an intelligent adaptation of planning, their machine technology and the whole peripheral equipment Wipak managed to adapt to this trend even with wide format printing machines

From Harry Sieljes - Efficient Short Run Production in Gravure is easier said than done. It is, anyhow, far more then just installing modern narrow web gravure printing equipment. Critical aspects are the pressroom organization that must be changed from a linear meters bulk generator to a set-up- and waste-control focus... [Show more]sed organization. The ink department and more-over the systems that enable to re-process press returns and as well the number of ink systems should be part of the short run philosophy, as is the attitude of the pressoperators (performing and maximizing change-overs instead of watching the machines printing) and the way working methods are implemented (such as pit-stop philosophy and parallelity instead of sequential working). Raw material waste in % is a major factor to be controlled, not only from the perspective of machine design- but also including ERP aspects. From an external point of view there are many limitations as suppliers from direct materials and tools do not, in real life, consider short run gravure as (potentially) major business. Finally, other print-technologies should be considered as well in the short run business, my initial scepticism regarding web offset for hybrid packaging purposes has been altered to web offset as a technology that starts to carry surmountable problem areas (critical issues are inks, web tension and machine hour-costs)

But: Was kind and amount of effort has to be given as input to get a good and reliable color matching during press run? What kinds of cost are coming up?

A lot of questions that will be illustrated during the presentation

From Jürgen Möller and Frank Woltering - Due to automation, new technologies and improved process control the price of rotogravure cylinders has come down in the past years.

Since the very beginning 4packaging is manufacturing rotogravure cylinders in a fully automated production line. During our presentation we will share some insides and describe the relation between physical cylinder properties such as type or dimension and their impact on the potential of automation. We want to initiate a discussion about a narrow web cylinder concept that allows printers and cylinder suppliers to maximize automation, bring down cost and make better business
