Stamp Image fields are available to individual, team, business, and enterprise levels of service
Stamp Images bring to electronic signatures the opportunity to replicate the “stamping” of a document with an official company seal, or to mark a document with a custom image stamp like 'Received', 'Completed', etc.
Stamp images fill a space between using an image as a signature, and the in-line images designed for collecting image data from Recipients.
Example use cases:
For Senders, Stamps can be added to templates by placing them using the Authoring environment, the use of Text Tags, or editing the name of a text field when building a form in Acrobat.
Stamp images are designed to either support the signature process with Company required stamps, or replace the Signature field for companies that prefer to sign with a company seal. As a result, the Stamp image inherits many of the properties of Signature fields:
Currently, the Stamp object can only accept a .png or .jpg/.jpeg file.
Placing Stamp fields on a document is best done in the Authoring environment because you have precise control of the field footprint.
In Authoring, you can find the Stamp object in the Signature Fields section.
The Stamp field is anchored at the top left corner, and is adjustable by "grabbing" the bottom right corner and dragging the field to the desired width and height.
The final image size is expressed within the Stamp field.
When placing the Stamp field using the Authoring environment, the field is flagged as Required by default. This can be changed by opening the field properties (double-click the field) and unchecking the Required box.
The Stamp Text Tag is uncommon as the tag must specify a height for the placeholder that is greater than the font used to create the tag (which is how field height is normally determined).
The argument to create a Stamp field is :stampimage(X)
Where X is the number of lines to be added to the field height.
The height of a "line" is determined by the font size used to create the tag.
For example: {{Stamp1_es_:signer1:stampimage(28)}} : height of field = 28 lines
Below is an example of the text tag on the right, and the resulting field on the left.
Keep in mind that the tag anchors the top of the field, and the number of lines added extend below the line where the tag is described.
This makes precision field sizing somewhat difficult, so if you need to have a precise field size, you may need to adjust the field in Authoring before saving the template or sending the Agreement.
Stamp fields may not be defined as "Read Only".
Adding a ! to the beginning of the text tag has no effect, and the field is accessible to the designated recipient.
Adding a Stamp field when building your forms in Acrobat requires that you insert the Text Tag syntax into the Name property of a text field (minus the braces on each end).
This hybrid approach does two useful things:
When placing a field in Acrobat, no argument can alter the size and shape of the field. If you include any number of lines in the text tag syntax, they are ignored, and the field size remains how you have explicitly placed it.
Recipients upload the Stamp graphic by clicking into the field, and selecting from two methods of import:
Once the image is in place, a large X is visible in the upper right corner of the field. Clicking this deletes the image from the field and returns it to its original state.
In all cases, the uploaded graphic retains its width to height size ratio. The image is not distorted by stretching or compression simply to fill the footprint of the field.
If the image is smaller than the field footprint. The image displays with its actual dimensions as uploaded, and is centered in the field footprint.
Below is an example of an undersized graphic centered in the field.
If the image is larger than the footprint of the field in either width or height, the image is scaled down until the whole graphic can fit the field footprint. This may result in the other dimension being smaller than the field space allowed.
Below you see a graphic that is scaled down until the width fits the field. The height of the graphic is relatively smaller than the field, so the graphic is centered in the field, leaving space above and below the graphic.
When enabled by the Account administrator, Stamp images can be used in place of a Signature field.
The Audit Log still captures the email and name of the person applying the image, but the typeset or written signature image is replaced by the company seal, or whatever graphic the company decides to implement.
There are a few things to remember when using the Stamp field as a signature:
Individual users can make this change on their Profile page by hovering over their name in the top right of the window, selecting My Profile, and then clicking Edit to open the profile in edit mode.
Change the unit to the desired standard, and click Save
Administrators can request that the default be changed at the Account or Group level by contacting Adobe Acrobat Sign Support or their Success Managers.
Changing the unit of measurement applies to all increments of measure that are displayed in the application, not just in Image fields.
The default minimum size of a stamp field is 1.6 (inches or centimeters) square.
During Authoring, the stamp can be re-sized larger than this size, but no smaller.
It is possible to have the default minimum size of the Stamp field changed to another value by request to the Acrobat Sign Support team. This absolute minimum size cannot be set at lower than 1 centimeter, or 0.393700787401575 inches.
Attempting to force a field size below the absolute minimum size results in a 1 cm field.
Navigate to Account > Account Settings > Signature Preferences > Additional Settings
Stamp settings can be enabled/disabled at the Group level through a request to the Acrobat Sign Support team.
