Full-hide finishing to debut at Simac by Gemata and Costa
Gemata and its subsidiary Costa will introduce two new leather finishing lines at Simac Tanning Tech 2025.
Full Greenfinish and Top Greenfinish systems claim to enable in-line upgrading of full hides for the first time, offering an alternative to traditional release paper methods typically limited to half hides. They are aimed at tanneries serving the automotive and furniture sectors.
Full Greenfinish uses a patented Costa process that combines embossing cylinders with a recyclable film, allowing grain imprinting at low temperature and pressure.
The technology has reportedly been in use for three years at a tannery in Arzignano and is said to improve yield, reduce environmental impact, and deliver uniform surface quality.
Top Greenfinish adds a spread-coating function to the film process, making full-hide finishing possible.
A prototype will be available for testing at Gemata’s Trissino headquarters from September.
Both lines aim to reduce chemical use, lower production costs, and increase design flexibility.
