RGB and CMYK

[Hessah]

We just did a flyer in publisher, and CutePDF'd it.. and we sent it off to our printer guy to print...

And it came back horrible, a bright green colour box has turned into a very dark green that we can barely see the black text in it..

He's telling us that we gave him a RGB file and it's not CMYK so that's why it came out like that...

I don't see anywhere on our Publisher or CutePDF where I can specify what colour mode we're using...

Anyone know any special settings that I should check next time?

[Blaaaaaaaah]

I'm on my phone at the moment so I can't paste the link but there should be a guide if you google publisher cmyk mode

Ohh ok I'll have a look thanks!
