"Increasingly, many "photographs" are digital and are therefore not
printed from a negative using traditional silver photographic
processing....but on a computer printer using "photographic paper" made
for those printers. What is the comparison of longevity of the images
from the traditional process and the computer printed images?"
Hi, I'm not an Archivist but a photographer by trade. So, I'll give you
my two cents worth on this.
Photographic prints are far move stable than the inkjet variety. Depending
on when the inkjet was produced, it may be water soluble and easily
discolured by exposure to periods of light. The same can also be said
about photographic prints but it would need extended periods of strong
light to discolour. However, photographic prints are not water soluble.
That being said, the older photographic prints are not as stable as todays
prints. If kept away from light and in a cool, regulated environment, all
photographic prints could in essence last hundreds of years. (Does this
sound like most mediums?) With todays newer inkjets, they are not
bothered by water exposure.
I would suggest that the photographic paper you are suggesting is good,
but the image itself is not of a permanent nature. As the image "sits" on
the surface of the paper it would be more susceptible to injury. In the
traditional silver halide process the image does not reside on the surface
but is almost "burned into" the paper and less susceptible to damage.
Todays computer printed images are often run through colour
copiers/printers/scanners. These prints are far more stable than inkjet
but still not as good as the photographic process.
I once remember reading a recent Kodak article that suggested that if the
prints were properly cared for, they could last for over 500 years. Mind
you, the same was said about long term storage of CD"s.
So... if you want to preserve your prints long term, use the traditional
photographic process.
