For many photographers and collectors, platinum and carbon prints come to mind when considering print types known for their superior permanence and archival quality. Both processes are celebrated for their longevity, but even with their reputation for durability, certain factors can compromise the long-term survival and quality of these artworks.
In this article, I begin an in-depth investigation into the primary issues and causes of degradation affecting the quality and permanence of 19th-century photographic prints, starting with platinum prints. My next article will cover carbon prints, offering a comprehensive view of these highly archival processes. I will also investigate silver gelatin, salt, collodion POP, and other historical processes in subsequent articles.
Why Platinum Prints?
Pure platinum prints were a common practice in the 19th century, and in the 21st century, platinum/palladium or palladium-only prints have become more prevalent. Although I have thoughts on why this shift occurred, that discussion falls outside the scope of this article. Both platinum and palladium have similar archival qualities, and for our purposes, a thorough examination of platinum’s archival potential inherently covers platinum/palladium or palladium prints. When processed to museum archival standards, a platinum or platinum/palladium print, under ideal conditions, can remain virtually unchanged for hundreds or even thousands of years. Given this consistency in archival performance, I’ll use “platinum” throughout the article to refer to these prints collectively.
Factors Affecting Longevity
Unlike silver-based prints, which are vulnerable to issues like sulfiding and oxidation, platinum prints are inherently resistant to these types of deterioration. However, certain factors must be carefully managed to maximize their lifespan.
In this article, I will outline the primary elements that can impact the longevity of platinum prints and offer insights on mitigating potential threats.
I am referencing primary literature in this space and not relying solely on my work or experience.

Tim, nice article. I can’t believe I forgot about your site, my bad. For collectors Platinum prints and carbon prints are some of the most if not the most archival prints one can make. As one who has exclusively printed carbon transfer prints for almost 20 years now I can tell you that it is important to the people who collect my work to know that it will still look like it does now for generations to come. Plus, we keep historic processes alive. It is not easy but so so important.
