Note: This posting refers mostly to black and white photographic prints, since that's the focus of my art and business. Longevity of color prints may vary slightly.
Most photographs printed today are inkjet prints. In the world of fine art photography, there are a wide range of processes in use, from the earliest antique processes, to traditional darkroom prints, to the latest digital prints on aluminum or wood, but the modern de facto standard is the inkjet print on paper.
Photographers and galleries now widely offer inkjet prints.
My ethical responsibility
Most of my clients probably don't question whether their new photograph will still be around when their great-grandchildren are adults, but I do. I care because this is my art — my life's work — I am ego-driven to create a product that will outlast me. Also, I see it as my ethical responsibility to provide my clients with the very best product I can create.
The types of prints I offer
While I offer several alternative types of prints like handmade cyanotypes and one-of-a-kind Polaroid-style photographs, the vast bulk of my work is offered in two print formats:
- Pigment-based inkjet on 100-percent cotton rag paper, and
- Museum quality fiber-based silver gelatin photographs.
I'll describe these two types of print in-depth below.
All inkjets prints are not created equal
Inkjet prints fall into two categories: dye-based inks and pigment-based inks. Generally speaking, dyes are not considered permanent and will fade more quickly than pigments. Pigments are also used to add color to other types of artists' materials like oil paints, and generally are more stable than the colors used in dye-based inks.
One thing to understand is that even black and white inkjet prints contain color inks. They are composed mostly of varying amounts of grays and blacks, but also have underlying amounts of all the available color inks.
However, black and white prints are vastly more stable according to Wilhelm Research.
They found that Epson's color prints using their newest HDX pigment inks on Epson brand paper will last between 62 years and 108 years under normal glass, depending on the type of paper used. UV glass nearly doubles print life in most of these.
However, black and white prints on the same papers under normal glass will last between 300 and 400 years or more (source). Under UV glass, all the black and white prints were expected to last more than 400 years.

My "standard" prints: pigment ink on cotton rag fine art paper
My prints use the latest state-of-the-art Epson HDX inks discussed in the tests above, on 100% cotton rag matte-finish photo paper. This paper is neutral-PH (also called acid-free). Not only is this paper archivally stable, it's beautiful to look at and to touch. However, don't touch too much because oils from your fingers can cause stains or degradation of the paper over time. Never touch the printed surface.
One of the problems with many matte surface papers is that they have limited dynamic range with muted blacks, but my papers have a beautiful tonal range, from rich, deep blacks to bright whites.
An advantage of matte papers is that they don't create a glare of light in the frame as glossy papers will do.

Silver gelatin — the gold standard in print longevity
My "premium" prints: Silver gelatin fiber-based prints
Silver gelatin prints on fiber-based paper have been called "the gold standard" in print longevity by the researchers at Wilhelm Research.
One caveat for that to be true: the prints must be developed, fixed, and dried properly to be at their most archival. I call my premium prints "museum quality." I make that claim because the lab I use to create my silver gelatins actually follows best practices to process prints to archival standards, and they actually do make prints for museums. These folks know what they are doing.
The collector's role in print permanence
A collector buys a photograph because they want to display it. Many permanence ratings are based on dark storage, which is unrealistic for art that's meant to be displayed and enjoyed.
So, what can the collector do to protect their investment in quality photography?
At the bottom of this article, be sure to check out the helpful resources from other pages.
The number one thing to do is invest in quality framing. Acid-free mats and mounts, and (as shown above) UV glass will really promote longevity in the artwork. Metal frames are preferred, but if you select a wood frame, be sure it has been buffered to prevent contaminants from the wood from leaching into the photograph or matting.
Protection against UV light
Light fades artwork. To protect your photographs, be sure to use UV glass and avoid displaying the artwork in direct window light, or under unfiltered fluorescent light sources.
Temperature, dust, and humidity
Proper framing and climate control will reduce the impact of the other enemies of photographs — temperature, dust, and humidity, as well as insects.
In some cases, with old family photographs for example, you may want to store the prints unframed. In this case, be sure to use a specially designed archival storage box, and whenever possible, put the individual prints inside a photo-safe poly bag.
Here are some various storage boxes on Amazon.

So, how long will the print actually last?
Studies by Wilhelm Research seems to indicate that the very latest printing technologies will well outlast our lifetimes, if handled with care. If you take care of your prints, they could potentially last hundreds of years with no visible fading. Color photographs slightly less.
If you really want to dig into the details of this topic, I've included several resources below for you to read more. The last listing, from Wilhelm, goes to their free ebook about print permanence.
