Cyanotype paper allows you to reproduce notes or diagrams in blue print. It has been in use since 1842 when Herschel developed it. It uses the action of light to create the silhouette effect. This process has been in use over years before the discovery of color photography. It does not require the use of camera to produce images and the resulting images are always blue.
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.
The process of mixing and coating involves substances with toxic elements. This therefore demands the use of protective cloths like masks, gloves and goggles. They protect your skin from damage by the chemicals you are handling. The market has provided premixed solutions which favor small scale uses. Mixing the ingredients on your own makes the process easier and economical for large scale operators.
The two chemicals mixed in the process are ammonium citrate and potassium ferricyanide. Instructions should be followed if desired results are to be obtained. They are mixed in equal quantities and used almost immediately. The solution does not have a long effective shelf life. Keeping it for a while will affect its effectiveness.
The process only works when the surface is exposed to UV light. This gives you perfect working conditions at night without worrying about protective lighting. The paper is coated and dried in a very dark place to make it more sensitive to the light.
Images are generated using the actual object or a negative of the object. The challenge while using the actual object is to fit it within a limited piece of paper. A negative can compress the image and make it fit on any paper size. The paper is then rinsed to initiate iodizing by removal of the coating substance. This is the way to reveal the images.
Images produced with the cyanotype paper are thoroughly cleaned of the chemical before drying. Ensure that the cleaning process does not make the images fade away. It should be done in moderation to avoid damaging the images. The final product is hung in the sun to dry or placed on a flat surface. It is the natural light that will trace your image on the surface.
