Platinum & Palladium

Used by the top photographers in history, Platinum/Palladium prints are at the pinnacle of excellence, longevity, and beauty.

At CEP, we’ve brought it into the digital age . . .

With our new invention “PiezoDN” we print digital negatives using up to 10 monochromatic inks. These negatives have ultra-high pin-point resolution and expanded tonal range comparable to the Platinum salts themselves.

Screen to Print Matching

With our new ink curve technology, we can match a screen image to the final print and even do a “hard-proof” of the image with Piezography on Hahnemuhle Photo Rag. This saves time & precious metal.


We use the Malde-Ware process of Platinum printing(Platinotypes). These are photographic prints made by sensitizing 50% Platinum and 50% Palladium with Ammonium Ferric Oxalate. This UV-sensitive solution is brushed or rod-coated onto a sheet of very pure paper and let to dry for a certain amount of time. We use two different sensitizers that control the final color of the print. We can produce very warm, warm, warm neutral, neutral, and cool neutral prints using the same 50%50% mixture of Platinum and Palladium salts. The addition of platinum adds smoothness and acuity in Malde-Ware. Because we are using 50% Platinum, these prints are considered Platinum prints rather than Palladium prints.  At Cone Editions Press, we produce very high-quality digital negatives and then contact-print the negatives against the platinum/palladium paper in a vacuum frame. These prints have extremely fine tonal qualities un-achievable by silver or inkjet printing. The Platinum/Palladium metal gets embedded into the paper fibers giving a unique luminosity. This form of printing truly glows with an inner beauty. When properly made, Pt/Pd prints last well beyond any other print-form and are sought-after by art collectors.


This Platinum/Palladium print service takes place in full-day chunks. The start of the day is spent in the imaging lab doing final mastering of files and printing proofs on Hahnemuhle Photo Rag. After the images have been finalized, PiezoDN negatives are printed. Then paper is coated in the darkroom and let to dry as chemicals are set up. After the coating has dried to a sufficient point, the contact-negatives and paper are exposed to UV light in a vacuum frame and then developed. The end of the day is spent finishing up and the prints are air-dried overnight. In the morning, we retouch the prints and flat-pack them carefully for transport. If needed, we are able to hard-proof the artist’s files before they arrive at CEP for Platinum printing. This will decrease any imaging time required and increase the amount of prints produced during the day. If the artist has photographs in negative form only, they must be drum scanned and finalized ahead-of-time.

Because we are able to calibrate each print perfectly, we are able to match our Pt/Pd prints to the artist’s image file. Whatever you see in the digital file is what can be printed in the final print. This is not a normal process for Pt/Pd. Normally Pt/Pd prints are much flatter and lighter than the originating digital files. This can be problematic when the Pt/Pd print does not match what the artist intended. Because we are not the same as other labs, what we offer is a “Pt/Pd Proof” service. This online service allows an artist to upload an image and receive a proof printed with Piezography ink on Hahnemuhle Photo Rag paper that perfectly matches the eventual platinum print without the huge cost of a platinum print. The artist can even choose to simulate different developers that will tone the print neutral, semi-warm, or warm. Of course, if the artist is looking for a “classic Pt/Pd look” they can choose that too and we’ll print the proofs with expanded mid-tones and open shadows. This way, an artist will know exactly what they will be getting when they send us a file for Platinum/Palladium printing: they can get a proof done, and adjust their file as-needed.


The PiezoDN negative is a new invention from Cone Editions Press. We found that printing with up to 10 shades of monochrome ink (from dark to light) enables incredibly smooth and dependable tones coupled with high-resolution, and very opaque dMax. These qualities are all required if you are going to spend $$$ on Platinum/Palladium salts. A Platinum print is only as good as its weakest link and usually that is the negative. With PiezoDN we finally have a negative that is capable of printing the fine details from a drum scan or high-megapixel digital camera. The negatives also have incredibly subtle tonal transitions and we can calibrate them perfectly.
