Inkjet Photo Print Longevity Lacking
Yet another Anonymous Coward writes to tell us about a piece up at the NYTimes on the (lack of) longevity of photos printed on inkjet printers. As the article's title says, somewhat alarmingly, "It isn't that images fade, it's that they can vanish." The problem is actually more nuanced than this; it's that no-one has a reliable and standardized way of testing inkjet prints for longevity. From the article: "The life of color inkjet prints has also been hindered by the origins of the technology, which was mainly intended for printing things like pie charts, said Nils Miller, a scientist at Hewlett-Packard. 'The initial emphasis was, how do we get bright colors on plain paper," Dr. Miller said. "Permanence was not really on the radar screen yet.'"
Who ctually expects something they print on a inkjet to last forever? Most people keep a digital copy as it and can just print off another copy if needed.
The old silver-based processes last a pretty long time. Same for the copper-based before that. There is a shop nearby that resurrected some very old metal plates used by a photographer in the early 1800s I think to document Indian life - and they are beautiful. But what lasts is that the images are either etched metal or metal deposited on glass or imbedded in the gelatin coating on paper.
But even conventional color film and photographs are just dyes and are subject to eventual fading. With black and white, you actually reduce silver halide to silver metal. It won't fade. But dyes are organic and will lose color as the dye molecules decompose.
One way to make inkjet images last longer is to protect them from UV light. A guy I know printed two identical images and hung them in his office. One had no protective cover and the other had a glass cover. The glass protected the dyes from UV degredation and that print still looks great. The one with no cover glass has very much faded.
People strive for some kind of lasting mark on society or evidence they existed and their lives mattered. The fact is that most evidence of any of us will eventually fade just the way it has for generations before us. Old fil got brittle, cracked, or was water damaged and stuck together. Old prints suffer similar fates. It's just by luck a that a lot of the old images have lasted.
Digital images have an advantage in that they are lossless and the data can be copied from media to media to keep them current and readable. But it is a maintenance that if you don't do, you will eventually lose the image. You can use a film printer to output images to actual film just like you had taken the image with a regular camera but are limited by the film printer's resolution and now you are back to having a format that can't be copied losslessly.
For lots of people, the only record they ever existed is either a headstone, or more commonly, just their skeletons. Might as well get used to the idea.
Or, and this is a crazy thought: don't rely on printed copies of digital photos.
Just pass around the bits themselves, and back those bits up.
I don't understand people's fascination with printing photos.
And supposing you did really want a printed copy, who cares if it disappears?
It costs almost nothing to make another.
I've inherited stacks and stacks of family photos and slides - and I can't get them through the film scanner nearly fast enough. I worry far more about those physical boxes and their handling, than I value their ability to hold up over time compared to inkjet printing.

No, not really. You see, unlike film, images digital images have the potential to last forever. It's a myth that film photographs will out last digital images. Who cares how long digital prints from a printer last? Ten years, a hundred years, the life time of a print is irrelevant. What matters is the life span of the original media; that be film or digital image. As long as you have that you can make prints.
Now here is the kick in the balls. Film degrades. Sooner or later the physical film media will decay into dust. Be it a 100 years or a 1000 years, soon or later that negative will cease to exist. The chemical process of developing the image also speeds that up. You see when you expose a negative the developing solution you start a chemical reaction that starts the process. When you put the negative in the stop bath it is suppose to "stop" the developing process. Well it doesn't. What it does is slows it to a crawl. The image on the negative may last forever to a human but the development process is still going on. One day that image will fade from then negative. The same thing applies to physical prints made from film images.
This is not true for digital images. They have the potential to last forever. As long as we have computers and networks we will always have the potential to view that image. That digital image has the potential to be as good 10 years, 100 years, even a billion years from now. Yeah, I know dvd degrade, harddrives go bad, and file formats will change. That maybe but physical digital media can be backed up and file formats can be converted. Film images can't. Once that image fades front the negative its gone.
