It's not like the thief needs those things in order for the watermark to
be a deterrent. The point isn't to warn off the thief: it's to embed
information in the image that can be used to prove ownership. It doesn't
have to be easily accessible to all.

But the screen capture technique introduces another problem. Take a
screenshot of a 600px wide image on your 96dpi resolution monitor, and
what prize do you end up with? A 600px wide image at 96dpi. Not exactly
stunning quality, and certainly not something that can be enlarged (on
screen or paper) to any significant degree. It has almost no value,
other than display on other screens. For fine visual art, screen
captures aren't much of a threat.
