The firm has forged ties with HP Indigo users Momentum Digital in Sydney and Melbourne-based Mercury Digital. It follows Moonpig's installation of an HP Indigo 3050 three months ago.

"We felt that HP's ink technology was different to anything else available, with a print quality the equivalent of litho," said Moonpig founder  Nick Jenkins.

He added that if the company was to expand into other countries, the US would be the most likely market, although there are no immediate plans to link up with digital firms there.

"Our customers in Australia will be able to order online and have their cards printed and delivered within a day," said Jenkins. "We hope that the Australian part of the business will grow to match the UK arm."

Moonpig was set up five years ago and has a turnover of 1m. It employs eight members of staff and specialises in online-ordered greetings cards.
