While every document can be marked in metadata and using footnotes, not every page can be personalized with an invisible watermark (see our article on marking). This is why we created the "Mark report" for each document: to give you full transparency about which pages can be adequately personalized with an invisible watermark, and which cannot.
In many cases, a page that cannot be marked isn't particularly private (e.g a title slide), but the current limitations in our invisible watermark technology mean that we cannot protect pages that lack text, or contain text that has been rasterized into an image. We also currently do not fingerprint images on pages. The report is designed to help you make an informed decision about how well your particular document is watermarked.
If your document is not personalizable enough, see our tips for increasing marked copies.
Accessing the Mark Report
You can access the mark report at any time by opening the document you want to view, opening the More (...) menu from the upper right, and choosing Mark report.
Mark Report Breakdown
1. Digital stamp applicability
Digital stamps can be applied to any PDF type regardless of its content. A digital stamp is a simple forensic key that is unguessable and hidden in the document metadata.
2. Footnote applicability
The visible footnote can be applied to most pages of most PDFs. If content on a particular page would overlap the footnote creating an undesirable appearance on your document, then the footnote will not be applied to that page.
3. Invisible watermark applicability
Each page of a PDF document can be invisibly watermarked only if it contains sufficient textual content. That means that documents with very little text, for example title slides, cannot receive an invisible watermark. It also means that scanned documents, where each page is actually an image from a scanner, cannot be invisibly watermarked. This section gives a summary of the page content, but each page's markability can also be viewed in the page list by pressing "Shore more pages"
4. Page list
Each page is analyzed for content that can be invisibly watermarked and the results are displayed in this section. Pages with more textual content can be invisibly watermarked for more total recipients.
