I think the answer is yes, and may be qualified by the choice of
spray, but EEM is not the paper to use because it is not acid free.
It actually yellows rather quickly. Best to use an acid free paper,
and there are many good ones to choose from. There is an article at
the link below called "The Great Paper Chase" which reviews about 26
different matte papers, with descriptions of their characteristics.
