The agency will be handling PR across EMEA, replacing Euro RSCG Biss Lancaster. Whiteoaks already handles OKI's UK business.
OKI is best known in the UK as the sponsor of Premier League football club Portsmouth FC. But the brand, which specialises in colour printers, is a major player in the b2b printing sector.
Laura Slade, head of client services at Whiteoaks, will head the EMEA account from London. She will report to Anja Jessen, general manager, brand and communications, at OKI.
