RUCO’s product portfolio contains a complete system of compatible inks, thus taking into account the fact that labelsare produced mainly in combination printing.
UV flexo printing ink series UVFX-LM
Low-migration UVFX-LM flexo printing inks meet the latest requirements of the label market. They are free from ITX, Benzophenone, 4-Methylbenzophenoneand silicone and meet the requirements of the “Nestlé Guidance Note on Packaging Inks”, Version 08-2016, Positive List 1A of the "EuPIA Suitability List of Photoinitiators" and also meets the specifications of the Swiss EDI on Consumer Goods (SR 817.023.21) regarding the external printing of food packaging. UVFX-LM inks can be applied with all commonly available UV flexo printing machines. Due to their low viscosity, they feature excellent printing characteristics. The inks are outstanding for their high colour strength and brilliance and feature excellent chemical resistance. In combination with other UV printing methods, optimal results are achieved even in stamping and die-cutting. 12 basic colours, a transparent white, as well as process colours for 4-colour set prints and an opaque white are available.
UV rotary screen printing ink series 905UV-LM
Under the designation 905UV-LM, RUCO offers low-viscosity, silicone-free and low-migration UV screen printing inks for rotary screen printing onto plastic films. The inks are characterized by very good flow properties, high opacity and colour brilliance. Due to their high reactivity, they enable high machine speeds of up to 60 m/min to be achieved. The inks also impress with their good resistance to solvents and water, as well as excellent resistance to fill products. 905UV-LM complies with the "Nestlé Guidance Note on Packaging Inks", Version 08-2016, Positive List 1A of the "EuPIA Suitability List of Photoinitiators" and also meets the specifications of the Swiss EDI on Consumer Goods (SR 817.023.21) regarding the external printing of food packaging. The ink range comprises 10 basic colours and a transparent white, process colours for 4-colour set prints, overprinting varnishes and the high-opacity preprint white 905UV1462LM. The latter is suitable for use with either rotary screen printing or flexo printing.
UV rotary screen printing ink series 965UV/MA
Low-migration inks of series 965UV/MA for rotary screen printing are universally applicable on a wide range of substrates. Thanks to their high reactivity, they offer good curing and adhesion properties even at high machine speeds. 965UV/MA inks are notable for high opacity and colour brilliance and provide good resistance to solvents and water. Stamping and die-cutting are possible without any problems. The product range consists of 10 basic colours and a transparent white as well as process colours for 4-colour set prints and a high-opacity black. In addition, a high-opacity, silicone-free white 965UV1425MA is available which can be processed using either UV flexo or UV screen printing. Series 965UV/MA complies with Positive List 1A of the "EuPIA Suitability List of Photoinitiators" and the specifications of the Swiss EDI on Consumer Goods (SR 817.023.21) regarding the external printing of food packaging.
Series 960UV varnishes
A wide range of series 960UV varnishes ideally round off RUCO’s product range for the label industry. Suitable for different application techniques, they help to achieve high resistance to specific media and eye-catching advertising effects. Deserving special mention in this context is the transparent and flexible low-tactile varnish 960UV501 which impresses with its high level of reactivity and excellent structure.
New: UV flexo release varnish 960UV504 for multi-layer applications and LED-curing UVFX-LED inks
Offering outstanding slip and release properties, RUCO’s new UV flexo release varnish 960UV504 represents a convincing solution for multi-layer labels. The varnish is characterized by very good printability at high speeds and good adhesion and wetting properties on printing inks. In addition, it features a lasting release effect against many commercially available adhesives. Compared to competitor products, the release varnish has a better static CoF value so that the first release from the overlayer is easier. The overlayer can be removed easily and evenly. Possible applications are lottery scratch tickets as well as peel-and-read and peel-and-reseal applications.
Catering for the trend towards the use of energy-saving LED curing technology, the RUCO product range now also includes UVFX-LED inks. These are silicone-free, offer high colour strength and brilliance and are suitable for combination printing. Due to the inks’ low viscosity, this series offers excellent printing properties.
All the above RUCO printing inks are carefully matched to each other and are designed to open up impressive opportunities for the production of labels with high potential to grab attention.
