Collaboration between Marabu and Koenig & Bauer, Partners launched an innovative digital printing solution for glass | New
CHARLESTON, SC, September 3, 2021 / PRNewswire-PRWeb / – Digital printing enables sophisticated designs and a high degree of customization at low cost. However, this process was, until recently, not suitable for three-dimensional decorations on standard glass products – instead, an expensive bespoke mold had to be created for each item. Now, Marabu and Koenig & Bauer have joined forces to create a pioneering solution to this problem. It offers manufacturers of glass products an attractive alternative to traditional embossing techniques.
Innovative inkjet solution for relief printing on glass
The manufacture of glass products with textured decorations conventionally requires various preparatory steps before embossing. This process is associated with high energy consumption and small production runs are prohibitively expensive. Each glass object to be given a decorative textured finish should be made with its own dedicated mold to produce a raised surface suitable for relief decoration. Production takes time and requires corresponding planning. However, embossing is not ideal for highly personalized glass articles, for which there is currently a high demand, for example, in the perfume and beverage industries, i.e. for wines, spirits and beer. Marabu and Koenig & Bauer have now developed an innovative inkjet solution that enables direct printing of highly customized glass products of all kinds, from one-offs to large volumes on an industrial scale – in conjunction with excellent results. . The contours, for example, are much sharper than with conventional embossing. Precise one-pass application of multiple coats of varnish is possible, producing extremely textured finishes. This is achieved with printing systems from the Kammann K15 and K20 family from Koenig & Bauer.
The process also enables printing of large areas, including color gradients, often required for brand logos. In addition, the textured varnish finishes can be combined with colorful elements to produce striking visual effects. All stages of the printing process are seamlessly integrated into the K15 and K20 systems. Servomotors are used to precisely position and move the object to be printed. This allows relief decoration of glass products of any shape. The corresponding varnish was developed in close collaboration between Koenig & Bauer and Marabu to ensure that it was perfectly suited to the printing process. During the development phase, the corresponding decorations achieved excellent results in terms of dishwasher resistance, resistance to chemicals and abrasion, in accordance with current standards. This simple but effective process is therefore a very interesting alternative to conventional embossing.
The benefits of Marabu high precision nail polish
The new Marabu varnish has been specially designed for digital printing of textured decors, especially on glass substrates. The precise printing method allows for extremely sophisticated and elegant looking designs on glass objects, such as perfume bottles, drinking glasses and beverage bottles. The number of layers can be changed according to specific customer needs. The use of this specially developed digital printing varnish allows the creation of highly personalized and personalized decors without sharp contours, extremely fine textures and precise points, colorful and transparent designs, printing of convex and concave shapes, and quick and easy adjustments during the printing process. Unit costs do not depend on volume. Any number of patterns can be applied to the selected glass product in a single print pass. There is no need for a minimum quantity of production or unique molds. The results comply with the requirements defined for resistance to the dishwasher: 500 cycles in industrial dishwashers and 50 cycles in domestic dishwashers. The varnish is also very respectful of recycling: the printing fully oxidizes without leaving any residue when the glass substrate is melted for reuse.
The megatrend of mass personalization
The demand for personalized products is increasing and can be seen in various fields: packaging, games, fashion, housewares and many other everyday objects. Consumers are also prepared to pay extra for such products. According to a survey by Deloitte Consumer Review, 30 to 50 percent of respondents are willing to pay up to 20 percent more for a personalized product. Manufacturers and retailers are reacting accordingly and are keen to find corresponding solutions. In this context, Marabu and Koenig & Bauer have pooled their skills and resources to enable very attractive designs to be produced quickly and inexpensively, without compromising on quality. “Cutting-edge technology has great potential when it comes to decorating glass”, emphasizes Tobias Lang, product manager for digital inks at Marabu. Tim schnelle, sales manager at Koenig & Bauer Kammann, adds: “Koenig & Bauer and Marabu have given the packaging industry an additional tool to tackle emerging challenges.” The new varnish and the matching printing method represent a unique glass decoration process that complements existing techniques.
