Cyanotype is the original sun-printing process and one of the earliest photographic techniques ever developed. Discovered in 1842 and distinctive for producing rich, Prussian blue monochromatic prints, Cyanotype was used well into the 20th century as an inexpensive method for reproducing photographs, documents, maps and plans (hence the enduring architectural term “blueprint”), as well as for making impressions of biological specimens in the field (“photograms”).
Cyanotype may be used to create detailed prints from virtually any object that casts a shadow: tools, toys, plants, leaves, stones, sand, string, lace, etc. Simply place the object on the sensitised surface and expose to sunlight (UV). By using a digitally-printed photographic negative (an inverted black and white photo inkjet-printed onto a transparency*) instead of an object, cyanotype may also be used to create full-resolution photographs on paper or fabric. Great for photographers, mixed media artists, printmakers, quilters, kids and more, the cyanotype process is easy, forgiving, quick, magical and fun. Harness the power of the sun—a great group activity for any age!
2 Component Set for photographic blueprints on paper and fabric
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.
Any natural surface, including cotton, linen, silk, canvas, wool, paper, wood and leather.
- Part A - Potassium Ferricyanide 0.8 oz/22.68 g
- Part B - Ferric Ammonium Citrate 1.9 oz/53.86 g
This set contains enough chemistry to make approximately 65 – 8.5”x11”/21.59 cm x 27.94 cm prints on paper or 50 – 8.5”x11”/21.59 cm x 27.94 cm prints on fabric, depending on the absorbency of the substrate.
