The move to use Quickcut on titles including the Saturday Guardian Weekend and the Observer's OM magazine signals the completion of a two-year project to introduce the system to both advertisers and gatekeepers.
GNL head of ad services Keith Fielding said: "Quickcut gives us files that are guaranteed to reproduce to our specific requirements. The bottom line is that it's the only product on the market that we're confident with and will meet our specifications."
But he added: "I'm always on the lookout to increase the method of supply for our advertisers and clients. Although we're with Quickcut at the moment I'm not going to stop there.
"What we want is something that will automatically drop ads into our system and go right through with virtually no manual intervention at all. That's what we're looking at at the moment."
Quickcut chief executive Joe Jarrett said: "There are a number of ideas and discussions happening between our two groups at the moment and we'll take it from that point at the moment."
He added: "This is the completion of a dream that both ourselves and GNL wanted to achieve the ability for GNL to re-establish itself as number one in the recruitment market and for Quickcut to prove our technology in the UK market."
Quickcut counts all the national newspaper groups among its clients apart from Mirror Group Newspapers and The Independent. Magazine publishers using the technology include Emap, NatMags and Reed.
