The new office in Northampton, which employs four print experts and three creative graphic designers, will handle creative design, in-house reprographics and externally sourced print services, as part of the contract.
Since April, CDS has won a contract with West Sussex County Council, Queen's University Belfast and Middlesex University before the Northamptonshire contract was awarded in August.
As well as opening new sites for each contract, the company has added staff and now boasts more than 200 employees across 14 sites in the UK.
David Burton, print and logistics director at CDS, said: "We understand public sector organisations want to focus on delivering their core services. We will help them meet best value, efficiency and sustainability targets."
CDS is now engaging with local print suppliers to get them on to the company’s approved supplier list, as well as using a national supplier base.
NCC marketing manager David Stubbs said: "CDS supports our sustainability objectives and is taking a number of steps to help NCC reduce carbon emissions."
Kirsty Neeson, strategic marketing manager at Northamptonshire Police, added: "We are delighted to be able to take advantage of the benefits the contract has to offer to Northamptonshire Police.
"CDS’s partnership approach and the goals we have set out to achieve in this joint contract align perfectly with our objectives to achieve cost reduction and ensure best value without compromising the quality of our communications."
