Blueprints are blue images of photographs or drawings. They are a rich cyan blue, thus the name Cyanotypes. The chemicals used to make them, potassium ferricyanide and ferric ammonium citrate, are also the basis of the artist's colour Prussian blue.


This kit from Rockland works by painting a solution onto watercolour paper to create a homemade sensitised paper.


You simply lay clear plastic over a negative or a drawing; expose using sunlight, then running water is all that is needed to make it permanent.


Unlike emulsions, Blueprint saturates the paper or cloth it's applied to, so the amount of coverage varies greatly. But normally, an ounce will cover a square foot, so one pint (500 ml) will cover about 24 size 8x10 sheets..

Aurora ★★★★★

The two-part chemistry set is incredibly straightforward—just mix the ferric ammonium citrate and potassium ferricyanide per the instructions and you get that rich, true cyan blue on the first try. I’ve made a dozen prints already and the 500ml bottle still looks barely used, which is great for the

Daniel M. ★★★★★

I mixed up a test strip and was pleasantly surprised by how evenly the potassium ferricyanide and ferric ammonium citrate blend together in this 500ml kit. The rich cyan blue tones came out exactly as I’d hoped for my first cyanotype print. It’s definitely worth the money for someone wanting to try
