An art director asks for a portfolio of your illustrations. You want to show your work but not give away high-resolution files until you're hired. The balance between showing well and protecting the IP is tricky.
Layered defences handle this elegantly.
Use a low-resolution preview
For initial review, share illustrations at screen resolution (typically 72-150 DPI) rather than print resolution. Lower resolution is enough to evaluate style and composition but not useful for reproduction. Compress PDF aggressively for preview versions; keep print-resolution masters separately.
Watermark visibly
Use annotate PDF to apply a diagonal watermark with your name and "PREVIEW — DO NOT REPRODUCE". Position so it can't be cropped out. Personalise per recipient if the work is going to multiple parties — leaks become traceable.
Password protection
Password-protect before sharing. Send the password by separate channel. This deters casual forwarding and makes the file feel as protected as it actually is. For especially valuable work, combine with watermarking.
Licensing note on the file
Add a licensing note in the file footer: "All work copyright [Your Name]. Preview only. Commercial use requires licence." This is legal cover and a clear signal. Even if the file leaks, the licensing terms are stated on the file itself.
FAQ
Are watermarks enough protection?
For deterring casual misuse, yes. For determined infringement, watermarks alone aren't enough — they're a deterrent, not a guarantee.
Should I register copyright before sharing?
Copyright exists automatically in most jurisdictions. Registration (in the US for example) strengthens enforcement options but isn't required for protection.
Can I share print-resolution work safely?
Only after payment for the specific use. Preview at lower resolution; deliver at print resolution post-payment.
What if my work is being used without permission?
DMCA takedown notices and direct legal contact via a lawyer. Keep evidence of the watermarked preview you shared as proof of pre-publication.
Show the work without giving it away. Apply protection in Flint and your previews stay previews.
