The JetSet and JetStar papers were relaunched as a result of improved performance following the upgrade. Applications for the papers include direct mail, reports & accounts, catalogues and brochures and the papers can be used with all leading high-speed inkjet printing systems, including those from Kodak, Océ, Screen, HP and Impika.

"This upgrade significantly improves the final printing results of JetSet paper and enables us to meet the growing printability requirements of customers in this segment," said a spokesman. "JetSet offers excellent image contrast when working with dye-based and pigmented inks."

JetStar surface-treated paper, meanwhile, was designed for use with pigmented inks and delivers colour stability, enhanced print performance and better fade and water resistance, said the company. It produces "visibly better results" over standard offset paper.

Both products are PEFC and Ecolabel certified, while the Saillat mill is one of the world’s best-performing sites in terms of CO2 emissions, with an average wood procurement distance of 128km, according to International Paper.

Inkjet papers brand manager Katarzyna Nieciag added: "The investment was a continued development of our value-added grades strategy at the mill."
