Yellow Highlight Marker Trick
When rubbing the back of a script with a yellow marker, you may OR may not cause an artificial watermark to appear. It all depends upon the ink used to print the artificial watermark.
In 2005, all paper was replaced by 92 or higher brightness paper. This brighter paper has made it more difficult to view the artificial watermark.
For this reason, many security paper manufacturers have added a slight amount of color to the artificial watermark. This produces an artificial watermark that meets all security requirements since it is impossible to duplicate. It is easy to identify and can also be seen at a 45° angle.
While using a yellow highlight marker may work, it is not a valid test nor recommended for use to validate an artificial watermark.

When held up at "just the right angle" to the light,
a security artificial watermark appears.
