1. If you make the height of the signature field rectangle larger than its width, Acrobat will place the date underneath the image in your custom appearance. Perhaps the height needs to be more than slightly larger than width for this to happen. You can experiment with this. I just tried and that's what I got when the height was approximately 1.5x of the width..
2. I am not aware of a way to control the font size of the date (or any other text) in the signature appearance. Generally Acrobat splits the signature field in two parts, one for image or name and the other for signer info in horizontal or vertical direction based on the height/width ratio of the signature field. I think Acrobat calculates the font size automatically based on the size of the area where the text is placed.
Do you know of any way to create a custom stamp which includes an image (the certified stamp) and a date? I see that some of the stock dynamic stamps do include the date in them. According to Washington State Law the certified stamp needs to include the date on it as well. Here was an example our reviewing agency sent us that was created using BlueBeam. Is there anyway to get close to this using Adobe Acrobat X?
Any thoughts? Thanks.
