We offer watermarking as a deterrent against art theft for designers who wish to have an added layer of protection. Watermarks make it more difficult for your work to be ripped from the storefront and better protect your interests. To opt-in for this, access your account settings page and click on "Watermarking". There, you can select 'Watermark my Designs' and make sure to hit the "Save Changes" button. And voila, designs in your shop will include a watermark!
For the best visibility of watermark settings, make sure to use a Desktop computer or laptop with the latest version of Google Chrome or Firefox.
If you ever notice any issues with this feature, reach out to us right away at community@teepublic.com so we can investigate!
