Clipping Paths produce white backgrounds on PDFs from InDesign

[LeTera_Haynes@adobeforums.com]

I made a PDF (Color) of an InDesign Document of which had a drop shadow on a pic with a photoshop(CS2) clipping path. The PDF produced a white background around the Pic with the drop shadow.

However, when a Grayscale PDF is made its a perfect file.

How do I get rid of/prevent the white background?

I am using Mac OS X 10.4.7

Stop using spot colors if you're printing them.

It sounds like you are using a spot color behind the image and transparency effect. Is that right?

If so, is it really a spot color job? If not, convert the spot color to process, and the problem should go away. If the spot color is truly needed, then you will need to have both your PDF viewer (e.g.,Acrobat or Reader) and your printer/RIP need to be set up to honor, not ignore overprint.

In Acrobat, turn on overprint support by using the Advanced > Overprint Preview menu option. In Reader 7, Overprint Preview is in the preferences, IIRC. I think Apple's Preview.app cannot be made to honor overprints. Depending on your printer/RIP, it may or may not be capable of interpreting overprints.

I have experienced this white box effect as well when generating color PDFs from IDCS 3.0.1. unless I choose Adobe 6 Layered as the PDF output. I am using Acrobat 5 on OS 10.2.8 (I know these are older systems/versions, but I have compatibility issues with other software/hardware), so I cannot use the viewing tip in Bob Levine's link.

But does this mean that only the VIEWING of the PDF is affected (i.e., creating the white box) and that the separations would print fine with the drop shadow effect rendering correctly with no white box? I only use the PDF as way for others to review a document before printing.

Thanks!

If you choose Acrobat 5 compatibility the white box shouldn't be there
at all.

Assuming that the "generating" referred to is by exporting from InDesign rather than Distilling or printing to Adobe PDF, that is.

WOW, THANK YOU, THANK YOU, THANK YOU! [Klonk!*] Such a simple solution.

I use this program every day (and have done so for about 1.5 years migrating from PageMaker 7), and there is still so much to learn... (and little time to learn it).

Thanks again.
