It has closed six locations where it had offices in close proximity, taking it from 22 sites to 16.
A spokeswoman said: "Our overall print sales force is expected to have reduced by around 20–30 people by the end of this gradual process.
"Roughly half of this reduction has been achieved by not filling vacancies, then taking into account retirements or staff choosing to move on, the number of actual redundancies is only in the low single figures."
She said just five staff had been made redundant and that, while the majority of staff had moved to new sites, where more significant changes to location had occurred, the company was in full consultation with the teams concerned.
The regional sales teams of Antalis and James McNaughton Group had previously retained their separate trading identities after the Antalis Group acquired Map Merchants, which included James McNaughton, in October 2007.
