Washington License Plates
Washington is now screening specialty plates and has been since March 2005. This includes plates such as the WSU alumni plates (which had been embossed since their initial release back in 1997), Vanpool plates, and vanity plates. The color scheme has not changed and the font used on the screened plates very closely resembles the dies used on embossed plates, so they don't stand out as much as the screened plates in some other states.
As of 2008, vanities are available on specials types, with a different Montana-style font. Also, Frank Astalosh reports that Trailer plates are now available for specialty types with numbering starting at 90000. Mike Kraft advises that specialty types for Motorcycle plates are also available with numbering starting at 95000.
