What is Cyanotype Paper?

Cyanotype paper is a unique type of photographic paper known for its striking blue color. It has been used for over a century to create beautiful, monochromatic prints. Here are some fascinating facts about this intriguing medium.

Invented in 1842: Sir John Herschel, an English scientist, invented cyanotype paper in 1842. It was one of the earliest photographic processes.
Blueprints Origin: The term "blueprint" comes from the cyanotype process, which was widely used to reproduce architectural and engineering drawings.
Anna Atkins' Contribution: Anna Atkins, a botanist, was one of the first to use cyanotype paper for scientific purposes. She published a book of algae prints in 1843.
Chemicals Involved: The process uses two chemicals: ferric ammonium citrate and potassium ferricyanide. When combined, they create a photosensitive solution.
UV Light Activation: Cyanotype paper is sensitive to ultraviolet (UV) light. Exposure to sunlight or UV lamps develops the image.
Washing Process: After exposure, the paper is washed in water to stop the chemical reaction and reveal the blue image.
Distinctive Blue Color: The characteristic blue color of cyanotype prints is due to the formation of Prussian blue, a pigment created during the process.
Durability: Cyanotype prints are highly durable and can last for many years without significant fading.

Uses of Cyanotype Paper

Cyanotype paper has found various applications over the years, from scientific documentation to artistic expression. Let's explore some of its uses.

Botanical Prints: Botanists like Anna Atkins used cyanotype paper to document plant specimens, creating detailed and accurate images.
Architectural Blueprints: Engineers and architects used cyanotype paper to reproduce technical drawings, giving rise to the term "blueprints."
Artistic Expression: Artists have embraced cyanotype paper for its unique aesthetic, creating stunning monochromatic artworks.
Educational Tool: Cyanotype paper is often used in educational settings to teach students about photographic processes and chemistry.
Textile Printing: Some artists use cyanotype techniques to print designs on fabrics, creating unique and durable textiles.
Photograms: Photographers create photograms by placing objects directly on cyanotype paper and exposing it to light, resulting in silhouette images.
Scrapbooking: Cyanotype paper is popular in scrapbooking for its vintage look and ability to create custom prints.

How to Make Cyanotype Prints

Creating cyanotype prints is a simple yet fascinating process. Here are the steps involved.

Prepare the Solution: Mix ferric ammonium citrate and potassium ferricyanide in water to create the photosensitive solution.
Coat the Paper: Apply the solution evenly to the paper using a brush or sponge. Allow it to dry in a dark place.
Arrange Objects: Place objects or negatives on the coated paper. Secure them with a glass sheet if needed.
Expose to Light: Expose the paper to sunlight or a UV lamp for several minutes. The exposure time depends on the light intensity.
Wash the Paper: Rinse the exposed paper in water to stop the chemical reaction and reveal the blue image.
Dry the Print: Allow the print to dry completely. The blue color will deepen as it dries.

Fun Facts About Cyanotype Paper

Cyanotype paper has some quirky and interesting aspects that make it even more fascinating. Here are a few fun facts.

DIY Kits: Cyanotype kits are available for hobbyists, making it easy to create prints at home.
Eco-Friendly: The chemicals used in cyanotype are relatively non-toxic and environmentally friendly compared to other photographic processes.
Historical Preservation: Some historical cyanotype prints are still in excellent condition, showcasing the process's durability.
Color Variations: While blue is the standard color, variations in the process can produce different shades and tones.
UV Sensitivity: Cyanotype paper can be exposed using natural sunlight or artificial UV light sources.
Creative Techniques: Artists experiment with different techniques, such as toning and bleaching, to achieve unique effects.
Photographic Negatives: Cyanotype paper can be used with photographic negatives to create detailed prints.
Alternative Surfaces: Besides paper, cyanotype solutions can be applied to various surfaces, including fabric, wood, and glass.
Revival in Popularity: Cyanotype has seen a resurgence in popularity among artists and photographers for its vintage charm and simplicity.
Cyanotype Journals: Some artists create journals filled with cyanotype prints, combining photography and storytelling.
Solar Prints: Cyanotype paper is sometimes marketed as "solar print paper" due to its reliance on sunlight for exposure.

Frequently Asked Questions

QWhat exactly is cyanotype paper?

Cyanotype paper, a marvel in the world of photography and art, involves a unique process using two chemicals: ammonium iron(III) citrate and potassium ferricyanide. When these chemicals are mixed and applied to paper or fabric, they create a light-sensitive surface. Exposing this surface to sunlight and then washing it in water unveils a rich, blue print. This technique, dating back to the 1840s, offers artists and photographers a way to capture images with a distinctive indigo hue.

QHow long does the cyanotype process take?

Timing can vary based on sunlight intensity and the materials used, but generally, exposing the coated paper or fabric to sunlight for about 15 to 20 minutes is enough. After exposure, rinsing the material in water will immediately start to reveal the final image. The whole process, from coating to drying, might take a few hours, but actual exposure time is relatively short.

QCan you use any paper for cyanotypes?

While you can experiment with various types of paper, results vary widely. Watercolor paper or high-quality cotton papers tend to work best because they can absorb the cyanotype chemicals evenly and withstand the washing process. Papers with a smooth texture and good absorbency levels yield the most detailed and vivid prints.

QIs cyanotype safe to work with?

Yes, working with cyanotype is considered safe, especially in well-ventilated areas or outdoors. However, it's wise to wear gloves and protective eyewear to avoid skin and eye irritation from the chemicals. As with any chemical process, caution and proper handling are key to a safe and enjoyable experience.

QCan cyanotypes be made in color?

Traditionally, cyanotypes are known for their beautiful Prussian blue color. However, creative variations and toning techniques can alter hues slightly. By introducing certain substances during the washing process, like tea or coffee, you can achieve sepia tones or even slight variations in blue. Pure colors beyond shades of blue and altered tones, though, are not typical of the cyanotype process.

QHow long do cyanotype prints last?

Cyanotype prints are remarkably durable and can last for decades or even centuries if properly cared for. Their longevity is due in part to the stability of the iron compounds in the print. To ensure your prints last, keep them out of direct sunlight for prolonged periods and consider using UV-protective glass when framing. Acid-free materials for mounting and storage also help preserve the integrity of the prints.

QCan you create cyanotypes on materials other than paper?

Absolutely! Besides paper, cyanotype enthusiasts often use fabrics like cotton, silk, and linen as their canvas. The process remains the same, but working with textiles opens up a world of possibilities for creating wearable art, decorative home items, and unique artistic pieces. Just ensure the material is natural and can absorb the cyanotype solution well for best results.
