The ISO 12647-accredited printer already has closed-loop colour control through Prepress Interface and Image Control, which between them monitor colour output on press and feed information back to the pre-press department.
Operations director Kenny Murray said: "Print colour management is a journey not a destination. In the past there's been a lot of subjectivity to quality.
"Everyone knows that there is incremental degradation and a printer producing six repeat jobs at different times will see some colour variation."
He added: "By working strictly to LAB colour measurement values with ImageControl you can fan the six versions out on a table and there will be no difference."
