lucite embedment is an option for an in home family heirloom. This
crystal clear acrylic will probably
last forever. The only thing you must be sure of is what you place
you use a photograph, it will eventually fade due to UV exposure.
The pigmented inks used today are very stable and have fade resistance
ratings over 200 years in some cases. But how will they hold up
for 1,000 years? My recommendation would be to use a laser print,
not an inkjet. Laser printers use solid particles that are said
to be UV stable. However, in certain circles there is some question
about that. There is a consensus that fading does occur
in some colors. This was published on the National
Archives of Australia's Website - "There is sufficient evidence
that colour xerographed images do not last as long as black and
copies. Most international archival institutions do not recommend
the permanent or long-term storage of colour photocopied or laser-printed
material." If you do use a laser print, be sure to use an
archival, non-yellowing paper. The problem with
laser prints is that the particles, over time, will
fall off the paper unless they are kept from doing so. Embedding
the print is the answer.
One website I visited will embed
a 7" x 9" document in an 8" x 10" x 1" thick
casting for $180, so the process is not inexpensive. And then there
is the association
of lucite with the awards, advertising, and promotional market.
Many people think of it
as just another piece of plastic. An heirloom to pass down through
the generations? I not so sure.
