Question for those few that have upgraded to Quark 7. I just got a PDF created from 7 that has shadows. It seems that when this file is exported to PDF Quark creates a white box that gets sandwiched between the tif image and the shadow. Unfortunately that white box is not in the same position as the tif image and creates a white line on edges of the tif. I was able to remove that box using pitstop but just wondered if anyone else is seeing this. It's a shame Quark still can't export live transparency as I also had to rebuild the front cover of this brochure by breaking up said cover into separate PDF's and rebuilding them in Indy using PDF import with transparent backgrounds and layering them back together. Of course the customer tells me, I've sent this same file to another printer and they didn't have any issues with it". I hate that...
I'd post the PDF but at 60 megs it's to big so instead here is a couple of jpegs showing what I'm talking about.

No idea WTF happened, a picture says a thousand words tho. Indy CS2. As you will see I can't see the right hand pages to well. Check it out and let me know if you have an answer.

So any brave souls install it yet? I've been reading horror stories all morning about issues it seems to have.

Navigate in the Finder (or your favorite file manager substitute) to:

/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ATS.framework/Versions/A/Resources/ProtectedFonts/

Here you'll see a copy of key fonts needed by the system. Delete the font from this directory first, THEN you can delete it from the /System/Library/Fonts folder.

You've essentially just broken Leopard's ability to repair itself as far as that particular font goes. But, in a pro publishing environment where your Helvetica is not the same as Apple's choice, that's something you sometimes have to do.

As far as I know, the major font managers have not yet been updated to deal with this change.

WARNING: don't try this at home if you're not sure what you're doing. This technique should only be used by experienced design/prepress users who simply MUST control their font destiny. If you remove Helvetica (for example) in this way, IMMEDIATELY replace it with the Helvetica of your choice PostScript, OpenType, TrueType -- but don't put it in the /System/Library/Fonts folder, instead put it in a higher-level place, like /Library/Fonts.

And in NO case should you ever remove the Lucida Grande, Keyboard, LastResort fonts.
