So, my sister is in control of her school's famous annual literary magazine, and last year she did it all in Word, and it came out terribly. This year, she hired me, and I convinced her to buy QuarkXPress 7. We've finished, and we've sent it to the printer, but the cover has so many layers that it will not convert to a PDF. So, I simply sent it in as a QuarkXPress 7 file, but the printer hasn't upgraded to version 7 yet, so they're asking me to "save down". How do I do this? I'm a little new at Quark. Thanks!
