Goodman watermark

A Goodman watermark is a technique used in digital imaging and printing to add a subtle, often semi-transparent mark—or pattern—onto an image. It's designed to protect intellectual property by making unauthorized copying or use more difficult, while remaining unobtrusive to viewers. The watermark can be a logo, text, or pattern placed strategically within the image so that it doesn’t interfere with the main content but still indicates ownership or copyright. This method helps deter piracy and confirms authenticity, acting as a digital signature appended to the image.
