Developing Processes


Cyanotype is a process of creating an image on a piece of paper or cloth using a chemical solution on the medium letting it dry printing out a positive image you want, then printing it on a transparency placing the transparency over the material and putting it the sun until the image is produced on the material.

“Cyanotype is an antique photographic process distinctive for producing Prussian blue monochromatic prints. Developed in the mid-19th century, cyanotype was quickly embraced as an inexpensive method for reproducing photographs, documents, maps and plans (hence the enduring architectural term “blueprint”).

Famously, it was also used by Ana Atkins and other field biologists for indexing plant specimens—the first photograms ever made! Cyanotype is a remarkably simple process that employs two inexpensive chemicals and sunlight/UV. Prints can be made on any natural fiber: paper, cotton, silk, wool, wood, etc.”

Quick Instructions:
Jacquard’s Cyanotype Set makes DIY cyanotype printing as easy as can be. The chemistry comes premeasured in lightproof black bottles. Simply fill each bottle with water to create Stock Solutions A & B and mix the two in equal parts to create the cyanotype sensitizer. Coat fabric or paper with the sensitizer and, once dry, create prints by exposing to sunlight or UV (3-15 minutes, depending on conditions), using objects or a film negative to create an image. After exposure, prints are processed in a tray of cool water and allowed to air dry over about 24 hours; prints will oxidize to their final deep blue color. To instantly oxidize the print to its final color, submerge in a dilute bath of hydrogen peroxide after washing, then rinse and dry.


Part A – Potassium Ferricyanide 0.8 oz/23.2 g
Part B – Ferric Ammonium Citrate 1.9 oz/54.4 g

This set contains enough chemistry to make approximately sixty-five 8.5”x11” prints
on paper or fifty 8.5”x11” prints on fabric, depending on the absorbency of the substrate.
