Export a set of .PDF files with unique code per file, like a security watermark.

---

Overview

This script saves a sequence of files in .PDF format with a unique number code per file in all pages of the file.

In default mode, the PDF Preset is Smallest File Size

If you want to change that, you need to edit the line #91 in the file with the name of your preset.

var myPDFExportPreset = app.pdfExportPresets.item('[Smallest File Size]');
