The Padstow, Cornwall-based academic book printer, which completed a £3.5m overhaul of its litho print and finishing kit last year, has now set about upgrading its digital book manufacturing equipment.

Managing director Angus Clark said that previous capacity had been insufficient to cope with the increased demand for digitally printed books.

As a result, the company bought a VarioPrint 6320 Ultra, which was installed last week alongside its existing 6250, and it is also set to replace its VarioStream 9210 with a 9710.

Clark said: "Our outlook for the future is that digital books are increasing at a much faster rate than litho and our view is digital will generate around about 25% of our total sales within the next two years.

"TJ has been partners of Océ for 10 years now – we've a proven track record. [The 6320] is without doubt the fastest on the market, technologically it's far more advanced than its competitors and, for us, it complements and enhances our existing facilities."

Clark added that TJ was still experiencing growth in its litho printing, partly due to a number of competitors going out of business and to the strong euro, although he said digital book manufacturing was growing faster.

Steve Wilson, Océ's UK director of production printing, said: "We are witnessing a big swing in the market with established publishers printing for distribution, not printing for warehouses. That is why there is so much growth in the digital book market."

TJ International was the first UK book printer to install an Océ DemandStream press in 1999. Five years later, it was the first UK book printer to install the Oce VarioStream 9210 and in November 2006 it became the first company in the UK to install the Océ VarioPrint 6250.

The Océ VarioPrint 6320 Ultra was launched at Print 09 and is currently the fastest cut-sheet monochrome press in the world.
