Advance Repographics, Flexpress, Lime PM, Print Matrix and Ultragraph have all joined, bringing the number of UK printers in the programme, which was launched at Ipex last April, to 11 out of 60 across Europe.
Oc sector marketing manager commercial Nick Chalk said: "The original UK Quality Centres have all shown positive growth in the past 12 months, and benefited from the enhanced networking opportunities, which included a European conference."
All of the member firms use Oc's CPS and VarioPrint technologies and are also part of the firm's Business Development Programme.
