The ”world’s first vegetable oil based sheet-fed offset metallic inks that are completely mineral oil-free” have been introduced by Sun Chemical. Known as Metal-Eco, they are said to meet the most stringent environmental requirements and provide improved runnability and metallic brilliance.
Sun Chemical aims to move 80 per cent of its conventional inks range to vegetable oil based products. It claims Metal-Eco is the first metallic ink to overcome the challenge of delivering excellent press performance, improved metallic brilliance and opacity and retain outstanding environmental credentials. Other beneficial properties promised are rapid setting and drying, excellent rub resistance and good printability.
Developed in a joint project with Wolstenholme International, the new inks are suitable for use on a wide range of substrates used in sheet-fed label and packaging. They can be used on all sheetfed offset presses. Metal-Eco inks are also duct fresh, produce excellent ink transfer, can be used on high stacks and are highly opaque, says Sun. No build-up occurs on blanket or plate and dampers remain clean – resulting in extended productivity for users, the company adds.
These metallic sheet-fed offset inks are available in the full Pantone metallic range as well as the classic metallic shades. They can be blended with Sun Chemical Pantone Inks (NPS) - also vegetable oil based - to produce Pantone polymetallic colours and other standard metallic colours.
