how long will my digital prints last

How Long Will My Digital Prints Last?Writen by Sally Jacobs

The question in the title of this article would be much easier to answer if you took
the word digital out of it. Color photographic printing has been relatively
unchanged since its debut, and you can expect those prints to last up to 100 years
if stored properly. [And by properly, I mean away from light in a consistently cool
environment without extreme highs or lows in humidity levels.

But anyone who hasn't been living in a cave the last five years knows that digital
photography is rapidly taking over traditional film processes. It's time to ask some
tough questions about what that means for the lifespan of your treasured family
photographs.

Manufacturer's claims. You're shopping in your favorite office supply
superstore and pick up a box of glossy paper for your ink jet printer. The box says
it will last 104 years. But how accurate is that claim?

Independent, third party testing. Thank goodness for Henry Wilhelm. His
company, Wilhelm Imaging Research, conducts research on the stability and
preservation of traditional and digital color photographs and motion pictures.

Brand matters. I'm not a rand loyalty at any cost kinda gal, but in this
situation brand really does matter. Manufacturer X designed their paper and inks to
work together, and it's in your best interest to use them the way they were
designed. Wilhelm's testing has proved beyond a shadow of a doubt that cheap inks
fade more rapidly. So while it's OK to use them for short-term documents, but it's
the wrong choice for photographs you'd like future generations to enjoy.

Inkjet vs. traditional prints. When properly stored, dyebased inkjet and
dye diffusion thermal transfer prints have stability comparable to that of traditional
photographic prints. But ink jet prints are more vulnerable to certain kinds of
damage:

Water damage. According to tests, traditional photographic prints are
fairly stable in water. Some types of digital prints are completely destroyed when
they become wet, while some are more water-resistant. Dye-based ink jet images,
for example, showed serious damage after even a brief immersion in water.

Pollution. Airborne elements such as ozone can cause some colors to
fade very rapidly. Some ink jet prints had this color shift problem less than a month
after printing. Photos encased in frames are less susceptible to damage from
pollution. Use use glass or inert plastic that is specially manufactured to block
damaging UV rays.

Personally, I've decided to skip the ink-jet altogether. I had some not-so-great
experiences with printing my own photos (and cutting them out - ick) before I
started researching ink jet longevity. Now, I upload digital photos to my trusted
local photo processor. The web interface is quick and painless, the prices are
reasonable, and I pick up my prints on my way home from work.

One final word of advice: Stay away from quickie one hour shops because
that rapid turnaround time doesn't always allow for proper rinsing. Residual
chemicals (no surprise) will cause prints and film to degrade more quickly. I also
noticed once that a popular online printer (they like to flood my in box with free
print offers) charged extra for trusted paper brands like Kodak. Hmmm... Something
to think about.
