At Glasstec 2018, Marabu will be presenting ink solutions suitable for the glass industry, including screen, digital and pad printing.
A particular highlight at their stand will be a singlecomponent ink for glass applications that is unique in character worldwide.
A world first: a single-component ink for glass and metal
One of Marabu’s highlights in Düsseldorf will be its single-component ink system Mara® Tech MGO for metal and glass. The baking ink can be used for both screen and pad printing, and can be deployed in a wide variety of scenarios.
MGO is ideal for printing on the first and second surfaces of flat and container glass. It is particularly suitable for the food and personal-care product industries. Mara® Tech MGO is BPA-free and highly resistant to chemicals, making it an outstanding solution for sensitive products, i.e. with heightened safety needs, especially baby bottles and medical supplies.
New screen-printing ink for touchscreens, panels and front panels
Marabu offers UV-curable and solvent-based inks such as Ultra Glass UVGL and Mara® Glass MGL for printing on glass touchscreens and touchpads.
Moreover, the company has developed the new two-component Mara® Glass MGLA for printing on second surfaces, i.e. on the back of the substrate – this is primarily employed for outdoor applications, including door intercoms, ticket vending machines, streetlight management systems (e.g. at airports or in pedestrian zones), and boat control systems. It is also suitable for lamination.
A broad portfolio of solvent-based and UV-curable inks
Although UV-curable inks such as Marabu’s Ultra Glass UVGL are increasingly popular, solvent-based inks remain relevant in many situations – particularly for designs with a single colour. In Düsseldorf, Marabu will be showcasing its solvent-based screenprinting ink Mara® Glass MGL, plus its pad-printing solution Tampa® Glass TPGL, which can be used as a four-colour system.
For both screen and pad printing, MGL and TPGL are compatible with diverse substrates, and deliver brilliant, precise colours. The two-component UV-curable ink Ultra Glass UVGL also cuts energy costs and upfront investment, and enables fast production processes for greater efficiency.
Elegant and eye-catching effects
Three-dimensional effects are both tangibly and visually attractive. Until now, manufacturers have employed casting technology to create visual effects on bottles and other glass items. This requires costly moulds, and is generally only commercially viable for very large production volumes. However, Marabu has developed an attractive alternative: its UVGL-RH/-RL ink can be harnessed to create tactile effects that could previously only be achieved via moulding.
A thick-film coating is precisely applied to a screen-printed design on flat or container glass – exactly matching the existing contours. It is then cured with UV light. In particular, the combination of the two varnishes enables the printing of highly diverse patterns.
The ratio of high-viscosity and low-viscosity components can be freely adjusted in line with the required results and printing parameters. Furthermore, hot foil stamping in conjunction with UV-curable screen printing continues to be in demand. This approach achieves brilliant high-gloss metallic effects comparable to precious metals – but is considerably more cost-efficient.
