If you place a
graphic on to a page which is in a file format that could
retain live transparency you will add that live
transparency to your layout. Once placed the graphic will
interact with other objects on the page and you can use the
graphic-manipulation features of the software to modify the
appearance of the graphic.
File formats that you could place into your layout which
might contain live transparency include:
Native Illustrator (.ai)
Native PhotoShop (.psd)
Adobe PDF 1.4
Adobe PDF 1.5
Adobe PDF 1.6
Adobe PDF 1.7
If your DTP appication does not understand live
transparency (Quark XPress 6.x and earlier)
you
should use flattened artwork for placement of transparent
content. Most advertisements
supplied for inclusion into magazine pages are now supplied
as PDF, and your PDF specification should reflect the DTP
software to which it will be imported/placed.
