Print durability is about the retention of image quality and chemical and physical properties of the print under varying environmental conditions, whereas print longevity is about the retention of artistic, sentimental, and/or historic value over time. Print durability and print longevity are thus related but are not the same. The printmaker makes important material and process choices affecting print durability. The print owner makes important curatorial and environmental choices affecting print longevity.
This website is dedicated to digital printmaking and to the preservation of prints and photographs. It is intended to foster a more meaningful conversation about print permanence (i.e., both durability and longevity) between photographers, printmakers, collectors, museum and archives specialists, and also manufacturers who want to provide more appropriate guidance to their customers.

April 15, 2014 – Updates for Batch L1
Updated reports for all thirty samples in Batch L1 were posted today. Batch L1 has now been updated to the new report format which contains graphs as well as tabulated results. The new graphs quickly reveal that all samples containing optical brighteners in batch L1 show some degree of light-Induced low-intensity staining (LILIS). The LILIS effect occurred at the 60 megalux hour exposure intervals in test because the measurements got delayed for several weeks after the samples were pulled from the light fade unit for measurement. This delay allowed the samples time to sit undisturbed in dark storage which in turn gave the OBA-containing samples time to develop some additional media white and highlight discoloration that is symptomatic of LILIS. See the notes section in each report of the OBA-containing samples for more information on LILIS.
The samples in batch L1 have now reached 90 Megalux hours of accumulated light exposure. Filter the database on [batch} [contains] "L1" to locate the updated test reports.
Some members of Aardenburg Imaging & Archives have generously donated money and/or samples to our digital print research program during the past year. You believe in our work, and we want to thank you for your continuing support! Here is an AaI&A logo that you can place on your website along with a link to AaI&A if you like. We hope it will help you promote your personal commitment to an informed understanding of the durability of modern digital printing processes as well as more public awareness of the Aardenburg digital print research program.
When you download and unzip this file, you will find a folder with small, medium, and large images of the AaI&A membership logo. The small or medium size images may be just what you need for your website while the large one is useful for printing or resizing to suit custom requirements.
