Original prints are NOT reproductions. Original lithographs are drawings
on stone printed in limited editions signed and numbered by the artist.
The same goes for etchings, collograph prints, and woodcuts. Once the
edition is printed, the printing plates are destroyed. This is an valid
original medium. That it allows for multiple copies does not diminish its
authenticity, but it usually allows for affordability. As long as one
realizes that when you buy a print numbered 2/20, there are 19 others in
circulation. Each has had the care and attention of the artist who has
printed all the color separations and inked each plate, and it is not being
run off by a factory.
Reproductions, where computers do four-color separations and where
esentially the artist is only instrumental in producing the first image,
are not the same as original prints!
If your students don't know this, they should. It might make for a
different spin on that aesthetic question. "How do Mr. Kincade's "prints"
differ from your linoleum (or whatever) prints?"
