Invisible watermark (high transparency)

Watermark transparency can be set as high as 98%, so it is barely visible in daily use and does not get in the way of work. If a screen image leaks, image adjustment may reveal the watermark details.

Platform

Limits and conditions
Watermark recognition depends on the settings, capture clarity and any later image processing; we recommend evaluating it in your actual environment.
