One lives and learns – I just gave this a try with Reader 9 (Edit > Preferences > Page Display category > activate ‘Show transparency grid’). The transparent background in the PDF is indeed marked using a checkerboard pattern.
Thanks Tom!

You can set Adobe Reader to show the page transparency by selecting “Show Transparency Grid” in Preferences.

That would be because you cannot. PDFs are treated like paper documents in acrobat reader (and all the other readers I know of) – it will not appear transparent unless you leave it as an editable pdf and open it in Photoshop. It will be transparent in photoshop, but will never appear transparent in acrobat reader. Instead, everything transparent will show white in acrobat reader, though as long as it’s an editable pdf, all the transparent information will still be there when opened in the appropriate editing program.

Thanks for the infos. I ran into the problem that my colors changed (from gray to blueish gray) in Acrobat Reader after I added transparency to a vector graphic created with pdfLaTeX and the PGF/TikZ package v2.0.

Thanks to your info about mixed CMYK/RGB colors I came to the idea to force CMYK colors onto the whole graphic, which fixed it. (Note to LaTeX users: simply load the ‘xcolor’ package with the ‘cmyk’ option)
