Marabu specializes in UV-curable organic glass printing inks, which are an efficient and energy-efficient alternative to ceramic glass printing inks. Potential energy savings can reach 65%.
Further savings in energy and CO2 emissions are possible with the Ultra Glass LEDGL UV-LED curable ink system. Unlike ordinary UV lamps, UV-LED lamps do not require any warm-up time. This enables high print speeds and cost savings as there is no need to enter sleep mode during machine downtimes or job changes.
UV-LED lamps are slightly more expensive but have a much longer lifespan and consume much less energy for curing than UV lamps. The lamps are mercury free and ozone extraction, which is standard with UV curing, is not required. These factors make UV-LED curing an economically attractive alternative. Durability is another advantage. Printed glass can be recycled after use.
Digital printing offers exceptional flexibility, allowing it to meet the growing demand for bespoke and personalized products. The new high build varnish Mara Shape DUV-HBV opens up new design possibilities for the digital decoration of glass bodies. Multi-layered glass reliefs can be perfectly reproduced and the contours always remain sharp. The process is ideal for printing ultra-fine haptic details, even on convex or concave geometries as well as taller and thicker graphic elements.
With Ultra Jet DUV-C digital printing, visual (color) and haptic effects can be combined and enhanced. The varnish oxidizes without any residue, which makes it recyclable.
An alternative is the Ultra Glass UVGL UV curable ink system for highly effective screen printing on glass. UVGL-RH/-RL relief varnishes can achieve haptic effects that are otherwise only possible with expensive molds and cost effective only when produced in very large quantities.
Pre-printed designs applied by screen printing on container glass or flat glass are congruently overprinted with a thick layer of varnish and cured under UV light. The combinations of the two varnishes make it possible to obtain a wide variety of effects.
Combined with the hugely popular hot foil stamping, UV screen printing achieves high gloss metallic effects with a shine rivaling that of precious metals. In addition, the production costs are much lower.
Marabu offers a wide range of inks and ink combinations for glass printing: screen printing, digital printing and pad printing. Its comprehensive product portfolio includes Mara Glass MGL solvent-based screen printing ink and Tampa®Glass TPGL pad printing ink.
Solvent-based printing inks are ideal for the multi-coloured decoration of glass. Whether used for screen or pad printing, both MGL and TPGL are impressive for their brilliant, well-defined colors on a variety of substrates. Mara Tech MGO one-component baking ink for glass and metal can be used for screen or pad printing and is ideal for first and second surface applications on container glass and flat glass. Maraz Tech MGO has high chemical resistance and, thanks to its BPA-free formula, it is an excellent solution for sensitive applications, especially on baby bottles and medical accessories.
For printing on glass front panels (touch glass) and operator control panels, Marabu offers the Ultra Glass UVG3C UV-curable ink system and two solvent-based screen printing inks: Mara Glass MGL and Mara Glass MGLA. Applications include automotive display cover glass and high quality operator control panels on kitchen appliances and similar equipment. The MGLA can also be used on outdoor surfaces such as jet skis and snowmobiles.
Ultra Jet DUV-C is designed for direct-to-glass digital printing, for example custom decoration of beverage bottles and cosmetic containers in filling lines. It also has uses in advertising and home decor. A uniformly applied primer as a bond coat greatly expands its applications with UV inkjet flatbed printers. The UV-PGL primer is applied by means of roller coating.
