Domino and Paragon Inks have developed a full suite of varnishes specifically for overprinting on Domino’s UV95 and UV90 inksets for use with its N-series inkjet digital  label presses.

The first set of varnishes, available as matte and gloss solutions, including thermal transfer overprintable versions, are for use with Domino’s UV95 food packaging compliant UV digital inkset. These are optimised such that the output does not need to be corona treated before the varnish is applied. This is said to simplify the complexity of hybrid printing lines, as well as providing an option for media that is unable to be corona treated, such as some metallic foils. During testing, it was also identified that the gloss varnish can be used as a lamination adhesive, enabling further simplification as one varnish can be used for two applications.

These varnishes have been formulated for many non-direct food packaging applications and, under the right conditions, are migration compliant. They are suitable for global use, being fully compliant with Nestlé, EuPIA, Swiss Ordinance Annex 10 and the North American TSCA (Toxic Substances Control Act). 

Julie Cross, technical director, digital printing at Domino, commented, ‘After listening to the challenges faced by some of our customers, we wanted to help them by providing a varnish optimised for overprinting UV95 printed output. We therefore set about finding a solution, ultimately deciding to work in partnership with Paragon Inks. And after 18 months of great collaboration between the two teams, we have developed a range of varnishes fully validated for compliance, and suitable for global use.’

To complement those varnishes intended for use with the UV95 inkset, a second suite of varnishes suitable for use with Domino’s general purpose UV90 inkset has been developed.  These are likewise available for global use, and have been fully validated for compliance meeting multiple legislations.

Amanda Jones, business development and marketing director at Paragon Inks, said, ‘We recognised that label converters were experiencing challenges applying varnishes to digitally printed labels. This partnership with Domino highlights how we have worked together as a team to develop a mutually beneficial solution for both organisation’s customers. We look forward to continuing to work with Domino in the future.’
