# PDF Stamp Modifier

**Applies to:** Lasernet Core 11

You can apply one or more text strings and images as stamps to pages in a PDF document.

You can enter text for the modifier to stamp. Images must be carried by a JobInfo as binary graphics in PNG, JPEG, or TIFF format before the modifier is executed. Similarly, if the stamp data is in PDF format, the PDF data must be carried by a JobInfo.

## **Notes**

The sheet design must be processed before using the PDF Stamp modifier.

The modifier can be applied at sheet or module level.
