Cyanotype paper produces blue prints of notes and diagrams using UV light. This is an ancient technology that has existed for centuries since its invention by Herschel in 1842. Exposing these papers under a certain chemical to light leaves a lasting image that was used in storing memories before advent of photography. No machines or cameras are used in producing the images.
It is a fun filled process creating images through a manual and natural process. This makes it interesting and rewarding considering that you will not require any machine. Caution must however be exercised to prevent blurring the images or distorting them. The surface is coated using a special chemical substance before exposure to UV light.
The image is generated from its negative or placing the actual object on the surface. This means that the chemical substance must be washed off the surface if the image is to be revealed. Uniformity is created when the same image is used repeatedly. This is how people in the old days managed to do mass production before the advent of modern printers.
The choice of water color papers to use should be informed by their features. The outcome can be jeopardized by coated papers that react with the coating chemical. Uncoated and non acidic papers are preferred. Natural textile is another alternative instead of using synthetic material. The natural selection produces incredible results.
Chemicals used in making the coating substance are mildly toxic and should be handled with care. This includes the use of protective clothing like goggles, masks and gloves as protection on bare skin. A premixed solution works best when the scale of work is not as much. Large scale users find customized mixing more economical and easier for their operations.
The chemicals mixed in order to form the covering substance are potassium ferricyanide which is added to ammonium citrate. Instructions on mixing and handling are provided and it is advisable to follow them. The mixture loses potency with time and should therefore be used immediately. This will guarantee reliable results.
Only natural UV light can react with the chemical to produce the images. It is therefore possible to do your work in a dark room under artificial light without damaging these images. The dark room provides the best conditions before the eventual exposure to the sun.
You have the option of using the image or its negative to generate the image. The actual object becomes challenging at times considering the expected sizes of some of them. This makes the option of a negative more viable because it is easy to fit any image on a piece of paper. You are required to rinse the paper to get rid of the chemical and allow iodizing to be completed.
The cyanotype paper is then cleaned thoroughly before exposing it to the sun to dry. Too much cleaning causes the image produced to fade and lose clarity. This erases or blurs some of the details on the print which makes it ineffective. A flat surface will be required for drying depending on the level of exposure in the area. The sun is what makes it possible to trace the object as a print.
