Wolstenholme International provides a range of metallic waterbased printing products available for a diverse range of print applications. The products have been designed to create excellent results on modern flexographic and gravure printing presses, also providing a series of inks for Tower Coater units. Our inks offer ease of use, consistency and repeatability of performance. Unipak® waterbased metallic inks utilize the latest developments in bronze and aluminium pigment technology in order to achieve outstanding printed metallic appearance. Brilliance levels are comparable with solvent based gravure metallic inks.

The inks offer excellent printability, minimizing the need to stop and clean the press. This can reduce printer down time, and contribute to cost savings. Unipak® waterbased metallic inks also have excellent clean-up characteristics reducing the washing up time of a printing press.

Other performance benefits of Unipak® waterbased inks include excellent transfer properties on a wide range of coated and uncoated paper substrates, low levels (less than 1%) of Volatile Organic Compounds (VOC's) and successful trapping over other colours under a variety of machine conditions and applications.

Unipak® MultiStrength is a recent addition to the Wolstenholme International Unipak® waterbased range. Unipak® MultiStrength is a competitive ink range offering quality and flexibility to the ink maker. The Unipak® MultiStrength strategy offers a range of ink strengths at prices close to the ink maker's own manufacturing costs, whilst maintaining the excellent performance characteristics of the standard Unipak® waterbased inks.

Wolstenholme International introduces a new range of products to our waterbased metallic range. RPC (resinated pigment concentrate) products combine formulation flexibility with state of the art metallic ink technology. This allows printing ink formulators to develop waterbased metallic inks for specific applications with built-in stability and performance provided trough the waterbased RPC base. Inks formulated with RPC can be used for flexographic and gravure printing on both coated and uncoated paper and board along with other absorbent substrates. Typical areas of application include pre and post print corrugated, gift-wrap, napkin printing and paper sacks.

With the introduction of Mirasheen™ waterbased, Wolstenholme International can now offer Mirasheen™ technology in all of the main printing ink chemistries. All Mirasheen™ inks provide a 'mirror-like' brilliant finish and are based on Wolstenholme's vacuum metallised pigment technology. Mirasheen™ inks are a cost-effective means of achieving foil-like metallic effects. They are designed for use on adapted tower coater units and for flexographic printing on coated paper and board. With modification Mirasheen™ waterbased can be used on filmic substrates and also be printed gravure.

To satisfy the increasing demand for more environmentally-friendly formulation chemistries, Wolstenholme International has launched Superoto® H2O, a range of bronze pellets designed for use in waterbased flexographic and gravure inks. Superoto® H2O products are supplied as pellets which incorporate stabilization additive technology that provides ease of dispersion and stability of finished ink systems. With very high metal content, formulators have maximum flexibility over final ink formulations. Superoto® H2O pellets are available in various particle size grades to suit the majority of applications where a bronze pigment is needed for use in a waterbased system.

Suitable applications include all printing applications where a waterbased gold ink is required including gift-wrap, labels, cartons and napkins.
