Check the signal strength meter
The signal strength meter helps you determine whether a watermark is durable enough to survive the intended use of the image.
Choose Filter > Digimarc >
Read Watermark. The signal strength meter appears at the
bottom of the dialog box. You can also display the meter automatically
by selecting Verify while embedding the watermark.The signal strength meter is available only for images containing digital watermarks that you yourself have embedded.
Digimarc recommends that you check the signal strength meter before publishing your images. For example, if you often compress watermarked images for inclusion in a website, check the meter before posting the images. You can also use the signal strength meter to gauge the effectiveness of different Watermark Durability settings that you are experimenting with.
