Thanks for the theory Niels, but this is a more general thing – I get files about different products/services at different times from different design agencies, and many have AW in the filename, usually after some other words.
e.g. “xxxx A5 booklet AW.indd” or “yyy English Top10 AW.indd”
The more I think about it, the more I’m sure it’s a (UK) thing for “artwork” – there’s nothing else in common.
Case closed, I think.
It’s hard to determine the nomenclature of a company, it might be regional or topic related. Here in Quebec you will see a lot of files with either EN or FR in the name, and it’s because we are a bilingual province and most files are made in both ENglish and FRançais (French). I,m guessing your best bet for an answer is to simply ask the people who sent you the file.
