Printing ink for glass decoration

At this year’s FESPA in Cologne, 18-22 May, Marabu will be showcasing its complete range of screen, pad, and digital printing inks.
To achieve high-gloss gold and silver effects, the glass industry generally employs ceramic inks. These are expensive to purchase, and the firing process is energy-intensive and therefore costly. Organic UV inks are cheaper, but do not produce the same glossy effects.

In Cologne, Marabu will present an attractive alternative: hot stamping with UV inks. The required image or text is screen-printed onto the glass surface with Ultra Glass UVGL primer, serving as a type of cliche for the hot foil. The foil is transferred onto the pre-printed ink film, either through roll-on stamping or vertical stamping – the foil only adheres to the areas that were primed with UVGL. The result is a high-gloss gold and silver finish at a much lower price.

Marabu’s Ultra Glass UV ink series provide the leading UV screen printing inks on the market. They feature the most comprehensive portfolio of their kind including basic shades, metallics and etch imitations. As a universal ink solution for glass printing, the Ultra Glass UV ink series have proven their strengths in the market for years.

Marabu’s UV glass inks can be used even more flexible: In addition to conventional UV-curing with iron and mercury lamps, there is also an Ultra Glass UV-version for UV-LED-curing available –another plus for the Ultra Glass ink series.

Additionally, Marabu will present its Mara Glass MGL solvent-based screen printing ink and the new Tampa Glass TPGL pad printing ink for glass decoration. MGL is ideal for high-gloss results on flat glass.

Durable TPGL ink is suitable for a variety of tasks, and performs especially well on rounded objects such as small glass jars for cosmetics. Both MGL ink for screen printing and TPGL ink for pad printing adhere well to a wide variety of substrates, and ensure brilliant precise colours. These inks were developed in line with the latest standards, and according to strict EU directives and hazardous materials requirements.

Printing on packaging

Marabu’s screen and pad printing inks can be used to create unique designs on packaging of all shapes and sizes. For printing on PET bottle closures, pad printing ink Tampa RotaSpeed TPRS or the halogen-free TPHF deliver efficient, cost-effective results for rotary systems. High adhesion and rapid drying mean seamless production processes and finished products that are scratch-resistant, even when packaged in bulk.

The new Ultra Pack LEDC is a LED-curable screen printing ink which delivers excellent results in terms of adhesion, opacity, degree of gloss, and reactivity. It is suitable for container printing and flatbed label applications. The good opacity works especially for full area prints or text.

Inkjet printing directly onto PET or glass bottles opens the door to completely new possibilities in pack-aging designs. Depending on system configuration, it is possible to complete smaller custom jobs or large-volume production runs at very high speeds.
