Zink Twice about Polaroid

Warning: Polaroid cameras that produce Zink photos are not recommended for preserving memories.

Polaroid or should I say what’s left of Polaroid continues to push instant photography, including cameras that produce Zink direct thermal prints. Camera models include Snap, Snap Touch, and Pop. Zip is an instant photo printer. The cameras and printer are available at Target, Walmart, and other mass retailers.

Direct thermal prints contain all the chemical necessary to produce the photo. Unlike with conventional photography, nothing is removed during processing. Stability is a concern since the chemicals that are necessary to produce the photos at elevated temperatures are also likely to react at standard temperatures, destroying the photo.

Polaroid and Zink have chosen not to provide any stability information on their products. One can only assume that the expected lifetime for this product must be poor, since if it were not, they would have every reason to publicize it. Simply saying that the prints are “long-lasting,” as DP Review did in their review of the Polaroid Pop does not make it so.

I wrote Zink about Zink in 2013, and the situation has not changed since then. No more information is available now than was available five years ago, and Zink is still not recommended for scrapbooking and other projects intended to preserve memories.

Note: Fuji Photo Film previously developed Printpix, which uses similar thermal technology. Fuji published stability data indicating that their product had a life expectancy of eight years when displayed and 12 years when stored in an album. Unfortunately, Zink is not the same as Fuji, and there is no reason to believe that Fuji’s stability data also applies to Zink’s products.

November 26, 2018: I received some additional information from Michael Zhang at Petapixel:

One challenge Zink Imaging scientists faced in developing the technology was image longevity, but Wicker says they leapt that hurdle. “It’s important for photographs to be archival. It took us a long time to really perfect the technology, but we have; and Zink prints will last as long as a typical photograph,” he states. “We determined that with accelerated testing of the media under a variety of different conditions. For example, we put the paper under very, very intense light sources, which simulates being in sunlight for multiple years. We put it under hot and humid conditions to see what happens. By placing Zink prints in those environmental chambers, we’re able to predict how long an image will last. The results have been very encouraging they will last for years and years and years.”
“Instant prints right from your digital camera? Zink Imaging makes it possible..” The Free Library. 2007 PMA Magazine

The Photo Marketing Association published this information in 2007. The problem is that this report has no details and cannot be evaluated independently.  Without data, the claims are meaningless.  If Zink wants their claims to be believed, they need to either publish the technical details through the IS&T or other similar organization (Fuji’s approach) or have the claims validated through an independent testing laboratory, such as Wilhelm Imaging Research. Because they have not taken either approach, I cannot recommend their products for applications involving photo preservation.

    I was gifted one of these a couple of years ago. As much as I like it I also don’t like it. I had better luck with the real Polaroid of years ago.
