Palladio Co. produced a paper with a platinum or platinum-palladium emulsion that allowed to realize an exceptional quality standard because of the uniformity of the emulsion spreading.

Besides, the packaging contained some precious strips very useful for the test prints.

The Ultrastable was a system for the colour printing that was inspired by the carbon printing. It had been conceived to be used with scanned images, we have used it with Kodak Tri X big format to realize the four colour negatives necessary
for the contact print on Ultrastable paper.
Very interesting results have been obtained from the multiple printing of B/W sheets.
