Make Stamp with Transparent Background

You need a stamp made with vector (Illustrator, InDesign, InkScape…), these are the only ones that allow the transparency of the background.

Anything made with pixels (Photoshop, GIMP…) cannot have a transparent background when imported in Acrobat, which does not support PNG nor GIF alpha chanel.

The Magic Wand tool is still there, hiding under the Quick Selection tool (which I think is actually more useful).

Thanks, but in CS4 Photoshop there is no magic wand....

Hi Andrew, Here's tutorial which at least will explain a little better than I can: http://mainheading.com/how-to-isolate-an-image-with-photoshop-cs2/

That all being the same, if it's a quick and dirty graphic,

Photoshop:
1. Use the magic wand tool, select the background
2. Select->Inverse
3. Layer->New->Layer Via Copy

The image you selected should now be on it's own layer.

Delete the background layer.

Save as a Photoshop PDF with the layers button checked.

FWIW,

I figured this out.

Save the image, with a transparent background as a TIFF and select "Save Transparency" on the dialog box when saving.... WORKS!

THANKS for all the comments and help.

"1. If you want to use an image for a stamp, open it in Photoshop and isolate the image on it's own layer. Don't flatten. "

How exactly you "isolate" the image? What is the best image format to start with, a PDF, JPEG, TIFF or what?

I tried to make it but result is still with non-transparent, white background.

Also - is there a way to remove the frame from stamp?

Also do a search on Dynamic Stamps if you want dynamic content. That's a bit tricker, but very cool, nonetheless.

Hi Larry,

I get it, your looking for a stamp with an image that is clipped but not transparent. For instance, if you if you had a triangle shaped logo stamp, there wouldn't be a white box behind the triangle?

If so, it can be done by creating a custom stamp.

1. If you want to use an image for a stamp, open it in Photoshop and isolate the image on it's own layer. Don't flatten.

2. Save the image as a Photoshop PDF and make sure you have layers check box selected in the "Save As" dialog.

3. Next, go to Acrobat and under:Comments->Comment and Markup Tools->Stamps->Create Custom Stamp.

4. Browse for the layered Photoshop PDF, click okay.

5. Select a category for the stamp (you can create your own category by going to Comments->Comment and Markup Tools->Stamps->Manage Stamps) and name the stamp.

The new stamp should be waiting for you in the stamps palette.

You can do the same thing with vector graphics in Illustrator as well.

Lemme know if you have any questions.

Good luck,
Dave

FAZAI,

Found it, but not intuitive.... thanks. BUT, when I do the slider, it makes the stamp AND the background transparent, so the stamp disappears. What am I doing wrong? Thx
