Cyanotype
Explore everything you need to make cyanotypes: complete kits, separate chemicals, suitable paper, fabric and practical tools. Cyanotype is a historic photographic process that uses UV light to create characteristic Prussian-blue prints. It is accessible for beginners, but also offers plenty of control for artists, photographers, schools and workshops.
What do you need for cyanotype?
The basic process uses two solutions: ferric ammonium citrate and potassium ferricyanide. Mix equal amounts shortly before coating paper or fabric, let the material dry in the dark, place a negative or object on top and expose it to sunlight or a UV lamp. Rinsing the print in water reveals the blue image.
For a reliable start, choose fresh chemistry, an absorbent surface, a soft brush or coating rod, and a frame or glass plate to keep the subject flat during exposure.
Cyanotype kit for beginners or separate chemicals?
A cyanotype kit is the easiest way to begin because the components are correctly matched and instructions are included. Separate chemicals are useful when you already know the process, want to make larger quantities or need more control over your workflow. Store mixed and unmixed solutions away from heat and direct sunlight.
Which paper works best?
Choose an uncoated, acid-free paper that can absorb the solution and withstand washing. Watercolour paper is a strong choice because it has good wet strength and is available in different textures and weights. Smooth paper preserves fine photographic detail, while a textured surface gives botanical prints a more handmade character. Browse our paper for cyanotype and select a format that suits test strips, contact prints or larger artwork.
Cyanotype on fabric
Natural fibres such as cotton, linen and silk usually accept the solution better than heavily treated synthetic fabric. Pre-wash the textile without fabric softener, allow it to dry and test a small piece first. Keep in mind that washing, detergents and alkaline water can affect the colour, so handmade textile prints should be treated gently.
Tips for a deep blue print
- Coat the material evenly and let it dry completely in the dark.
- Use good contact between the negative or object and the coated surface.
- Make a small exposure test because sunlight changes with the season and weather.
- Rinse until the water runs clear and let the print oxidise fully.
- Record your coating and exposure times so successful results are repeatable.
Work safely and carefully
Follow the instructions supplied with the product, wear gloves, protect your work surface and do not use cyanotype chemicals on food-contact materials. Keep all chemicals clearly labelled and out of reach of children and pets. Whether you are making your first sun print or refining a professional process, the right materials and a few controlled tests will give you cleaner, more consistent results.
