>>And so where can I find this cool Australian design mag -- Barnes and Noble
or its ilk, I hope?  Does that article about good blacks concern itself
only with PhotoShop??<<

Most bigger bookstores like B&N or Borders will carry it under graphics or
computer. The article primarily focues on Photoshop techniques for dealing
with (mostly) Photoshop issues with printing a pure black from a CYMK file.

The Design Graphics does a really good job of whatever they cover. I have
many back issues saved for reference. I wish some US publisher would follow
suit. Its oversized and comes out every two months. It really sits
inbetween those big expensive volumes like HOW and a monthly rag. The price
reflects this.
