Preview shows pictures in PDFs as negative pattern

Question

Preview shows pictures in PDFs as negative pattern

Hi all,
I got several Fine-PDF-documents for print-usage from our prepress company. Those PDFs are made by Adobe-Distiller. When opening those PDFs in preview I am able to see the text like it should be, but the pictures (included jpeg’s) are shown as negative pattern.
When I use PDF-Reader to take a look on these documents, everything looks right.
Right now I only figured out, that this occurred only under Tiger. Using preview under Panther everything is fine.
Can everybody give me a hint or advice what to do????
Thanks in advance.

Thanks for your replay.
Yes, you are right, I could take the Reader, but I try always to use Apple-own-applications. Another thing is, that I use the ability of “preview” or ”automator” to shrink those PDFs (with Quartz-Filter "Reduce-File-Size"), so that I can send them by e-mail or put them on our Web Site.

I have to correct something.
Those PDFs are made by the professional workflow-software "Twister" from Dalim-Soft (www.dalim.com).
I got already in contact with them, but they told me, as long the PDFs are shown right under Panther, it is a probably a Tiger-Problem.

After longer research, I probably have the reason of Tiger’s problem. Since Tiger, preview is no longer able to view PDF-1.3 Softmasks of pictures in PDFs. So Apple has to produce a patch to fix that problem. Hopefully they will read this topic and do there work.

Thank all for there help.

I am having this same issue.

Trying to create a Reduced size PDF using the Quartz filter in Automater. The output PDF views in Acrobat as a negative image. Preview views the file correct.

I emailed the PDF to a client for approval and he opened in acrobat which showed the negative.

It seems to me that Preview is saving the file so it can only be viewed correctly by preview.

Any thoguhts Apple?

My advice is to use PDF-Reader instead of Preview.

Does that pose any problems you're not telling us about?

How are they creating the PDFs? I tried duplicating the behavior and I can't seem to get either Distiller 6 or 7 to make a PDF that inverts the JPEGs.
