PDF Watermarking

Available Watermark Features

The supplied application description confirms:

Opening Watermark

Select Watermark from the navigation.

Direct route:

#/watermark

General Workflow

1. Open the Watermark tool.
2. Choose the PDF document you want to modify.
3. Select a text or image watermark.
4. Configure the available watermark settings.
5. Specify a page range if needed.
6. Generate the watermarked document using the tool's controls.
7. Review the resulting PDF before distributing it.

The exact control names and output filename are determined by the Watermark module, which was not included in the supplied source.

Text Watermarks

Text watermarks use a string as the visible overlay.

Typical examples include:

DRAFT

CONFIDENTIAL

FOR REVIEW

SAMPLE DOCUMENT

These are examples of watermark content, not built-in presets confirmed by the supplied code.

Common Uses

Text watermarks are useful for:

• Draft documentation
• Internal review copies
• Sample documents
• Preliminary contracts
• Documents awaiting approval

Choosing Watermark Text

Use concise wording that communicates the intended document status.

Avoid making the text so prominent that it prevents the document from being read.

Image Watermarks

Image watermarking uses an image as an overlay.

Potential applications include:

• Company logos
• Brand marks
• Visual ownership labels
• Organization emblems

The precise supported image formats depend on the Watermark module.

Considerations

Image quality, transparency, aspect ratio, and placement affect how the watermark appears in the resulting PDF.

Use a sufficiently clear image appropriate for the page dimensions.

Tiled Watermarks

Tiled watermarking repeats the watermark across the document page.

This arrangement can make document labeling more visible across the full page.

Example Concept

DRAFT        DRAFT        DRAFT

      DRAFT        DRAFT

DRAFT        DRAFT        DRAFT

The pattern above is illustrative and does not reproduce Papercraft's exact rendering algorithm.

Suggested Uses

Tiled layouts are often useful for:

• Review documents
• Samples
• Internal distributions
• Documents requiring repeated status labeling

Diagonal Watermarks

Diagonal watermarking places watermark content at an angle.

Example:

CONFIDENTIAL

displayed diagonally across the page.

The tool's feature description confirms diagonal watermarking, but the exact rotation angle and positioning options are not established by the supplied code.

Opacity

Opacity controls the visibility of the watermark.

The actual numeric range and default value depend on the Watermark module.

Choosing Opacity

A lower-opacity watermark may be preferable when the underlying text must remain easy to read.

A more prominent watermark may be appropriate for sample or draft labeling.

Review the output to ensure the watermark does not obscure essential information.

Page Ranges

Page-range support allows the watermark to target selected pages rather than necessarily every page.

For example, a document might require watermarks only on its internal review pages.

The exact page-range syntax and accepted values depend on the implemented Watermark module.

Example Use Cases

PDF Watermarks and Security

A watermark is a visible document annotation or overlay.

Watermarking is not equivalent to encryption, access control, or secure redaction.

A watermark does not inherently prevent someone from:

• Copying document contents
• Editing a PDF
• Extracting embedded text
• Taking screenshots
• Recreating the document

Similarly, placing a watermark over sensitive information does not securely remove the underlying information.

Recommended Workflow

1. Keep an original copy of the PDF.
2. Choose clear watermark text or an appropriate image.
3. Select the watermark layout.
4. Adjust opacity.
5. Choose the intended pages.
6. Generate the output.
7. Review all affected pages.
8. Verify that the document remains readable.

Troubleshooting

Watermark Is Difficult to See

Review its opacity and the contrast against the PDF background.

Watermark Obscures Text

Reduce its visibility or change the configuration where supported.

Unexpected Pages Are Watermarked

Review the page-range selection.

Image Watermark Looks Distorted

Check the original image's dimensions and aspect ratio.

PDF Processing Fails

The input may be incompatible, malformed, encrypted, or too large for available browser resources.

Important Considerations

• Test watermarking on a copy of the original.
• Inspect pages with unusual dimensions.
• Review watermarks on both portrait and landscape pages.
• Do not use visible overlays as a substitute for secure redaction.

Important: Watermarks communicate document status or ownership but do not guarantee confidentiality or prevent unauthorized distribution.
