Colman was an engineer at de Havilland, and in 1945 he co-founded Hawthorn Baker along with his colleague Jack Thomas. The company traded as Cornerstone and Colman was chief executive.

Cornerstone became famous for its state-of-the-art equipment, in particular its lightweight letterpress furniture and honeycomb base, which found favour with printers because it allowed users to position plates accurately and easily.

After success in its home territory, the firm expanded into export markets across the world and became a major employer.

Peter MacLachlan, who worked in sales for Cornerstone, paid tribute to Colman's vision and business acumen. "He was a fantastic man, so innovative. He deserves recognition for what he achieved. He was known around the world."

Colman retired in 1979, when the company was sold to Dunlop.

His son, Baden, said: "We feel sure many printers will recall the Cornerstone products, and Henry and his team."

The funeral will take place at St Nicholas Church, Harpenden, at 1.30pm on 23 November and industry associates are welcome to attend. Details from Weston Funeral Directors on 01582 712865.
