Converting graphics with transparent background to pdf

[KMM]

Whenever I try to convert a Publisher file that contains grahics (.png) that
have transparent backgrounds the graphic in the resulting pdf is poor. There
is often shadowing and some "bleeding" of the graphics into what should be
transparent.

How can I avoid this?

Thank you.

What is the .png resolution? What are you using as your PDF converter? What
version publisher.
Is the image one that you created?

Sorry, I guess I left a lot of info out!

I'm using Publisher 2003. It is an image I created in Photoshop CS2. I
eliminated the background of a .jpg and then saved it at a .png. THe
resolution is about 600 dpi., but only 2.2"x.6" in size.

I've tried converting it with two different converters: Distiller from
Acrobat 5.0 and CutePDF. I've tried it in CMYK mode and RGB mode.

In researching it sounds like Publisher just can't handle the "layers." Is
that true? I've found a work-around and that is to open the bad looking pdf
in Photoshop (which looks just great when I open it there) and then have
Photoshop save it as a .pdf. It is just cumbersome when it's one of 12 pages
of a newsletter. I then have to replace the page in the newsletter .pdf with
the one I created from Photoshop. I was hoping there was a way to do it from
Publisher to save the extra steps.

Thanks so much.

Can you insert the original .jpg into Publisher and use Publisher's native
transparency tool. This will work if the image's background is all one
color.

What a neat tool. I never knew about that! Thank you. When I use that it
works and looks great in Publisher, just like the .png file, but the .pdf
look the same -- poor.

Any other suggestions?

Try a different PDF converter. Maybe www.primopdf.com
I can take a look at it tomorrow late. I'm away so I haven't access to my
regular email. If it isn't a rush publication...

Thanks. I'm downloading primopdf now. I'll try that. If it doesn't work, I'll
send you and email with the page from the newsletter and the .png and the
..jpg file.

Thanks so much! So generous!

Was this problem ever solved? I'm having a similar problem with transparent PNG's > PDF's and I haven't been able to find a resolution. I end up with an awful looking low resolution PDF with strange ugly drop shadows in the PDF. Fingers crossed - hoping you found a solution!
