The Sussex-based mailing house has installed a Xerox Nuvera 288 and Xerox DocuColor 8000AP, which it believes will increase print capacity by around 30%.
According to the company, the machines will allow it to work quicker "with enhanced output quality for its print and mail clients".
Ian Cameron, managing director at AMM, said: "Modernising and expanding our print capabilities whilst others look to downsize and decrease costs, leaves us perfectly placed to continue to grow the company. Enhanced capabilities provided by our investment with Xerox are central to our strategy."
The Xerox DocuColor 8000AP and Xerox Nuvera 288 will boost AMM’s existing digital portfolio, which already includes DocuTechs and a Xerox DocuColor 6060.
Cameron added that the new equipment will also bring greater flexibility in the scheduling of jobs and reaction times for emergency orders.
AMM will produce a range of work on the machines, including council tax bills, newsletters, reference manuals and financial statements.
To celebrate the investment, the company held an open day to demonstrate its new digital capabilities and applications to customers.
Cameron said: "The recent customer event was set up to demonstrate to our customers AMM's continued investment in new digital print equipment and what this means in terms of new opportunities for companies to communicate more effectively with the end user.
"The installation has allowed us to maintain our market share in what has been a difficult period for the industry. This move is the first part of a five-year plan to increase the company turnover by 75%."
