Make sure, before you apply the transparency, that the white fill is not set to overprint ( attributes dialog box / menu ). Sounds like you are using Illustrator or InDesign. Hope this helps.
I am using Indesign CS5 and I already checked the overprint in attributes but when I save out a high-res pdf the box disppears.....low res pdf its there???
What attribute do you use for the 'opacity' in InDesign? Do you use a custom swatch color or do you use 'Effects' panel?
If possible, give us a screenshot of what we're discussing here - that should make it easy for us to help you out.
I was adjusting the opacity through the effects window/tools....
This is the screen shot from INDESIGN file and how the file is set up..... the effect opacity level was set at 85%
This is how the the hi-res pdf was exporting from InDesign and I have all attributes check and nothing is set to overprint....
and this is what the pdf SHOULD look like.....
****and I had to sit there and mess with this pdf FOREVER.... and how I was finally able to export the pdf properly was by using a different PDF export option...
The printer I use has a set profile that I am suppose to use for the pdfing of the final hi-res pdfs to be uploaded to the press....
But when I went and used the pdf-x-1a option it was fine.
Does any one know which setting in the pdf profile that would have affected the opacity to not carry over???
I am going to email the printer directly to see what they have to say and possibly suggest making the correct adjustments so this does not happen in the future....
It's solely on a case-to-case basis.
I'd like you to answer a few questions to enable us come up with the reason for your PDF not printing without setting to PDF-X-1A option:
1. Are you using Mac OS?
2. Is your PDF printer the default Mac OS install or do you have Acrobat Pro installed as well?
3. Is your indd document CMYK or RGB colorspace?
4. If it is CMYK, have you set custom options for overprint colors?
By default, 'white' is not an overprint compatible color as there is no printer that 'prints white'. If/ When you choose to 'overprint white', you instruct InDesign that you want white 'knocked out'. This may possibly be a reason as if white is set as a custom overprint color, it may not appear in your PDF/ final print output.
Have you by any chance grouped the 'white' layer with other layers? If yes, do you have any other custom knockout/ overprint set to your other elements of the group?
This topic really belongs in the InDesign forum.

No printer prints "white". White is more of a default mode wherein nothing is printed. How about if you convert your output into a format where every element is cemented into one. In that case, what the printer will be printing in the area you had issue on will be the texts and shadows.
Exporting and importing of images between different platforms can be tricky like that. I'm not sure where to start troubleshooting your problem, but your printer should be able to help you somewhat.
