I'm just curious why everyone is so concerned about the print life
of paper and inks in this digital world? Since printers continue
to get better and printing a digital pic is very cheap, why worry
if the print doesn't last 25 years or whatever. Just print a new
one. You'll probably have a much better printer by the time your
first print wears out anyway even if it last only a few years.
Maybe someone can share a good reason why there is so much fuss on
this issue.
I, for one, couldn't be less concerned about photo longevity. I
totally agree that it's more important to take care of the digital
files than the hard copies.
Photos fade, regardless of what method you use to produce them.
More importantly, there are many risks to photo printouts besides
fading. Many photos are ruined because of other damages than
fading. When a photo becomes less than perfect, which is
inevitable, what makes a difference is whether you can restore it.
Digital photography has a huge advantage over traditional film
photography in this regard. As long as you have the digital file,
just print another and you have an equally good or even better
photo than the original.
The key to photo longevity is taking proper care of your photos.
Keep them in albums. Avoid direct sun light, extreme heat and
humidity. But more importantly, store your digital files in a safe
place.
If a photo is so good that you still want it 50 years from now, you
want it on whatever the best media you can get at that time, not on
the inkjet paper printed with the printer you bought last year.
