Tresu develops Indigo metallic option

Tresu has introduced a new option for adding metallic finishes to folding carton that’s aimed at those companies using HP Indigo’s 30000 B2 folding carton press.

The Tresu Flexo Kit is used to apply special finishes such as metallic effects (shown in this photograph) to the folding carton package.

The Tresu Flexo Kit is designed to be integrated into Tresu’s iCoat coater but is specifically meant for use with the Indigo 30000. The Flexo Kit uses printing sleeves and consists of a dedicated anilox roll, chambered doctor blade and pump. This keeps the various coating finishes, such as gold, silver and aerodyne, separate so they don’t contaminate each other.

Tresu says that it can keep up with the press and coater, running at 4600 sheets per hour. The ink flow is completely enclosed so that the viscosity and pressure can be maintained to avoid foaming. It also features automatic cleaning for relatively fast ink changes while the anilox rolls use elongated cells to handle relatively large particles without clogging.

Kim Krintel, vice-president of Tresu Digital Solutions, explains: “Metallic inks are an essential requirement for folding carton niches such as chocolates and confectionery, and flexo is the ideal process for achieving the high-gloss effect. Tresu Flexo Kit enables digital converters to add this high-value embellishment with minimal extra logistics, inline and at fast speeds.” 

It can be added to existing iCoat units, and can be specified for inclusion on new machine orders.
