Gray, who was the driving force behind the BPIF's lean manufacturing consultancy Vision in Print (ViP), will continue to work with the BPIF "off-payroll" on a part-time basis. He joined ViP 2003, having previously held a number of senior roles within the industry, including three years as chief executive of Pindar.
Gray, a keen advocate of the industry's need to adapt and change, steered ViP from it's formative years, when it was a DTI-funded, through to it becoming self-sufficient prior to its merger with the BPIF in 2007.
"I am very proud of the impact the ViP team has had in the promotion and development of lean manufacturing across the UK Printing Industry," said Gray. "[However], I took this as a good, if unforeseen, opportunity to move, whilst I was still young enough to tackle new challenges in the industry I know and love."
Gray will remain in his current position until the end of June, after which he will continue to work for a number of days a year as the BPIF's commercial adviser. His departure is part of the industry body's drive to reduce costs and streamline its senior management structure, and follows this week's retirement of Brown, which was revealed in December.
Brown has spent 30 years at the BPIF, the last five of which have been in his current role, and he too will continue to support the organisation on a part-time basis.
"I've agreed to do a number of days for the BPIF, which will involve looking after its main policy committees," he said.
"This includes driving our lobbying action, and also continuing to run our paper committee and technical standards committee. We have a joint partnership with the union, and will continue to work collaboratively with them."
The changes will mean that just two executive directors will now report to chief executive designate Kathy Woodward, who will take the helm at the BPIF following the departure of outgoing chief executive Michael Johnson's at the end of June.
"I am keen to see a simpler management structure adopted at the BPIF, with a smaller top team and more devolved responsibility to regional directors and departmental managers," she said.
