Digital Prints

Others who do their own testing include photographer and monochromatic inkjet expert
Paul Roark and also photo artist Barry Stein, who constructed a fluorescent fade tester for
under $50 that allows him to test with and without a glass filter and to adjust the light
level from 20 to 60 klux (see Figure 5.10).
For more ideas about individual-artist testing, see “Do Your Own Permanence Testing” below.
So How Long Will It Last?
I started off this chapter asking two simple questions: How long is long enough? and How
long will it last? That second one is the hardest to answer. Because there is no one answer;
because it all depends. Even the best outside permanence tests and manufacturers’ claims
will only give you a generalized guesstimate of what’s going to happen to your prints. There
are just too many variables. What is the atmospheric pollution level where the print will
be displayed or stored? What is the UV component of the light coming in from the windows?
What’s the temperature? What’s the humidity? These are just some of the influencing
factors that will significantly affect the permanence of that print.
What Can You Do?
To get closer to knowing about the longevity of your prints—besides waiting around a
few decades as they age, you have three basic options: (1) carefully study the existing test
data, (2) contract out your permanence testing, or (3) do your own testing. In any case,
you should also learn how to maximize print permanence.

Figure 5.10 Barry Stein made this
fluorescent light-testing device from
inexpensive parts including a foil-lined
trash can, light fixture, and fan.

rotating samples made from pieces of
Foamcore and a small motor. All this
for under $50.
