I'm about halfway through looking under blue light at the test sheets
submitted to EFF.  Here's what we've got so far, indicating how we know.
[exp] = looking with a blue light; [mfr] = manufacturer said so;
[press] = press report.  Remember that a "no" simply means that we
couldn't see yellow dots; it does not prove that there is no forensic
watermarking present.
