Jesse,
I think I have replicated your problem... and found a solution - of
sorts! I created an InDesign CS3
document with a background in spot colour. I then created text on
top of the background, selected the
text box and applied an effect - a transparent drop shadow(50%K).
If you DON'T want the spot colour to
be knocked out just select the text again, access the Attributes
palette and check the Overprint Fill option
to ON. To view the end (printed) result in terms of colour make
sure that Overprint Preview is ON (View
Menu).
only problem is that sometimes you don't want the text to overprint
(hardly ever an issue for black text, but just think yellow text on a
blue spot background...) but still want that drop shadow effect
You can view the resulting PDF in Acrobat using Advanced - Print
Production - Output Preview. Turn off the
the Process colours to see the spot colour. I kept the drop shadow
simple so I didn't experiment with any
Rasterising effects even though it was transparent and I also used
PDF/X1a.
You can also view a separated result in Acrobat by using the File -
Print menu, using the Adobe PDF
Printer and choosing Separations under the Output options. The
resulting PDF will have 5 greyscale
'plates', just as if it was output to film or CTP.
NOTE: In order for the background Spot colour to remain unaffected
by the overprinting text and drop
shadow the Overprint Fill option MUST be on in the Attributes box
in InDesign when you make the PDF
otherwise the spot colour in the resulting PDF will be knocked out.
It s also worth noting that, while this IS a colorsync forum and
not a PDF forum, there seems to be a bug
in Acrobat 8. Turning the Overprint Preview OFF makes the drop
shadow disappear! Over to you Olaf.
Where is Leonard when you need him?
that may be because it is sitting behind the spot color (which for
this purpose is also set to overprint)...
Adobe changed to this behavior as in earlier PDF creating versions of
the Creative Suite you were confronted with a white rectangle
'obscuring' the area where a drop shadow over spot was happening.
Now, if the viewing tool does not simulate overprinting, you won't
see the white rectangle, but it's the drop shadow that seems to have
disappeared.

PS: AFAIK Leonard is in the process of crossing the Atlantic ocean...
