The Glasgow-based company bought a Perfect 92TS guillotine from Intelligent Finishing Systems to complete the spend.
Managing director Stuart Mason said that the company wanted to move away from low-margin long-run work and concentrate on web-based offerings to businesses and consumers.
The company has launched mypeanutprint.com for consumers, while peanutprint.com is aimed at businesses wanting short-run on demand print requirements.
Mason said: "We want to focus on reducing non-profitable work substantially and increasing the bottom line profitability. We can’t rely on the business model of seven or eight years ago. With consumables and paper prices rising as well, the market is increasingly difficult.
"We wanted to be sure that our guillotine reduced manual handling as much as possible and was flexible enough to cope with the increase in short run jobs we expect our new business ventures to attract."
The guillotine joins a Xerox Color Press 1000 and a Presstek 34DI-UV that were bought to augment its short-run sales push.
Ink Shop employs 25 staff and has a turnover of around £3m.
