The question posed 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 "brand loyalty at any cost" kinda gal, but in this situation brand really does matter. ManufacturerX 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:
1. 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.
2. Pollution. Airborne elements such as ozone will cause some colors to fade very rapidly. Some early ink jet prints had this color shift problem show up less than a month after printing. The solution? Encase your photos in frames and they will enjoy an additional layer of protection from pollutants like ozone. Use glass or inert plastic that is specially manufactured to block damaging UV rays.
Personally, I decided to skip the ink-jet altogether. I had some not-so-great experiences with printing my own photos before I started researching ink jet longevity. Trimming the prints was a nightmare for me. 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. Suh-weet!
