I am using Acrobat 7 Professional. I see in their Stamp Pallet that there are several stamps that seem to have a transparent background but if I try to make a custom stamp, I cannot get this effect and all my home-made stamps have an opaque white box around them. I know this has been asked before but does anyone have any updated, new info on a way to do this?

Are you using text or images on your custom stamps? How are you creating them?

I can assure you that it does work :-) The most basic stamp is just text: Take a blank PDF page and use the TouchUp Text tool, hold down the Ctrl key (or the Option key on a Mac) and click on the page. This will create some new text. Edit it, select it and right-click, then select Properties. Change the font size and the fill color and then create a custom stamp out of this page. When you apply the stamp, the background will be transparent.

When you start with a file that was created by an application (e.g. Word), it's possible that the PDF file does no longer have a transparent background. Some apps fill the background with (non-transparent) white. This way, you will never get a transparent stamp. There are ways to remove the white background, but this depends on the application (hence my question about how you create your stamps).

I was trying to use a bitmap and hence the solid background. I discovered the options in my graphics program to save with transparent background but your solution works better. Thanks for the tips.

When you are using a transparent image (e.g. GIF or PNG), you need to import this image directly into Acrobat, and not printing it to the Adobe PDF printer. Only a direct import ("Create from File" in Acrobat) will preserve the transparency, and, you have to use an image format that actually allows transparency.

You certainly sent me in the right direction. I didn't know Acrobat could import from so many formats. I also then discovered in the Stamp Menu that I could paste a "stamp" from the clipboard although I couldn't find where I could make a custom stamp from the clipboard contents. I'm learning all kinds of things today. Thanks, again.
