Understanding Sun Printing on Fabric

The History of Sun Printing

The art of sun printing, also known as cyanotype, dates back to the early 19th century. It was invented by Sir John Herschel, an English scientist, who discovered that certain chemicals, when exposed to sunlight, would undergo a chemical reaction that resulted in a blue-colored print. This discovery revolutionized the field of photography and eventually led to the development of sun printing on fabric.

The Science Behind Sun Printing

Sun printing relies on the reaction between light-sensitive chemicals and ultraviolet (UV) rays from the sun. When these chemicals, such as potassium ferricyanide and ferric ammonium citrate, are applied to fabric and exposed to sunlight, they undergo a chemical reaction that creates a permanent image on the fabric. The areas of the fabric covered with objects or designs block the UV rays, resulting in a negative print, while the exposed areas turn blue or a shade of another color depending on the type of chemicals used.

The Relevance of Sun Printing Today

While sun printing originated as a photographic technique, it has evolved into a popular art form in its own right. The unique, organic, and unpredictable nature of sun printing on fabric appeals to artists and crafters who seek to create one-of-a-kind designs. Sun printing offers endless opportunities for experimentation and creativity, allowing artists to explore various techniques and materials to achieve stunning results.

Materials Needed for Sun Printing

Fabric Types for Sun Printing

When it comes to selecting the right fabric for sun printing, certain types work better than others. Natural fibers, such as cotton, linen, and silk, tend to absorb the chemicals and produce more vibrant prints. These fabrics also have a smooth surface, which allows for better contact between the chemicals and the fabric, resulting in clearer and crisper designs. It is recommended to avoid synthetic fabrics as they may not react well with the chemicals or retain the prints as effectively.

Sun Printing Paints

The key to successful sun printing lies in using the right type of paint. Sun printing paints, also known as light-sensitive dyes or fabric paints, are specifically formulated to react with sunlight and create vibrant prints. These paints typically come in a range of colors and consist of light-sensitive chemicals that react when exposed to UV rays. Look for paints that are specifically labeled for sun printing or cyanotype to ensure the best results.

Additional Tools and Materials

In addition to fabric and sun printing paints, there are a few other tools and materials that can enhance your sun printing experience. Some useful items include brushes for paint application, spray bottles for creating unique effects, stencils for precise designs, and a UV light source for indoor sun printing. You may also want to have a water source nearby for rinsing the fabric after exposure to sunlight and a clothesline or drying rack for drying the prints.

Preparing the Fabric

Washing and Ironing

Before you begin the sun printing process, it is important to prepare your fabric properly. Start by washing the fabric using mild detergent to remove any dirt, chemicals, or sizing agents that may interfere with the printing process. Avoid using fabric softeners as they can leave residues on the fabric. Once the fabric is clean, iron it to remove any wrinkles and ensure a smooth surface for printing.

Creating a Flat Work Surface

Having a flat work surface is essential for achieving even and consistent prints. If you are working indoors, clear a table or a countertop and cover it with a plastic or vinyl sheet to protect it from any spills or stains. Outdoors, choose a clean and flat area where you can lay out your fabric without it being disturbed by wind or other elements.

Securing the Fabric

To prevent the fabric from moving or shifting during the printing process, it is important to secure it in place. You can use masking tape or clips to hold the fabric taut on your work surface. Make sure the fabric is stretched evenly and tightly to avoid any wrinkles or folds that may affect the quality of the print.

Choosing and Creating Designs

Using Natural Objects

One of the most exciting aspects of sun printing is the ability to incorporate natural objects into your designs. Leaves, flowers, feathers, and even everyday objects like keys or lace can be used to create interesting patterns and textures. Arrange these objects on the fabric in a way that pleases you, keeping in mind that they will block the sunlight and result in negative prints.

Experimenting with Stencils

If you prefer more precise and intricate designs, using stencils can be a great option. Stencils allow you to create consistent patterns or motifs on the fabric. You can either purchase pre-made stencils or create your own by cutting designs out of cardboard or acetate sheets. Lay the stencil on the fabric and secure it in place before applying the paint.

Hand-drawn Designs

If you have a knack for drawing or painting, you can unleash your creativity by hand-drawing your own designs on the fabric. Use fabric markers or paintbrushes to apply the paint directly onto the fabric, creating unique and personalized prints. This method allows for complete artistic freedom and the ability to create intricate details and shading.

Applying the Paint


Brushwork is one of the most common methods of applying paint for sun printing. Dip a brush into the sun printing paint and apply it evenly onto the fabric, covering the desired area. Use broad strokes for larger areas and smaller brushes for more detailed work. Experiment with different brush shapes and sizes to achieve various textures and effects.

Stamping and Block Printing

Stamping or block printing is a technique that allows you to create repetitive patterns or motifs on the fabric. You can use ready-made stamps or carve your own designs onto linoleum blocks or rubber erasers. Apply the paint onto the stamp or block and press it firmly onto the fabric to transfer the design. Repeat the process to create a continuous pattern.

Spray Techniques

Spray techniques can add a unique and spontaneous touch to your sun prints. Fill a spray bottle with diluted sun printing paint and mist it over the fabric. You can create fine mist sprays for a delicate effect or use a larger spray bottle for a more dramatic and abstract look. Experiment with different spray patterns, distances, and angles to achieve the desired results.

Layering Colors

To add depth and dimension to your sun prints, consider layering different colors of paint. Start with a base color and let it dry before applying another layer of paint on top. You can use multiple colors to create gradients, blend them together for new shades, or create contrasting effects. Layering colors allows for endless possibilities and adds richness to your designs.

Exposing the Fabric to Sunlight

Choosing the Right Time and Weather

The time of day and weather conditions can significantly impact the outcome of your sun prints. Ideally, you want to choose a sunny day with clear skies, as clouds can obstruct the UV rays. The best time for sun printing is typically in the morning or late afternoon when the sunlight is less harsh. Avoid direct sunlight during midday when the rays are the strongest, as they can cause overexposure and lead to blurry or faded prints.

Controlling Exposure Time

The exposure time required for sun printing depends on various factors, such as the intensity of sunlight, the type of fabric, and the desired outcome. It is important to monitor the fabric closely during the exposure process to achieve the desired level of color and detail. You can periodically lift the objects or stencils to check the progress until you are satisfied with the print. Keep in mind that different colors may require different exposure times, so experimentation is key.

Creating Patterns with Shadows

Shadows can add an interesting and dynamic element to your sun prints. By strategically placing objects or stencils on the fabric, you can create patterns or gradients using the shadows cast by the objects. Experiment with the placement and angles of the objects to achieve different effects. This technique can result in unique and captivating prints that play with light and shadow.

Indoor Sun Printing

If you don’t have access to direct sunlight or prefer to work indoors, you can still enjoy the art of sun printing usingUV light sources. These artificial light sources emit UV rays that mimic the effects of sunlight, allowing you to create sun prints without relying on natural sunlight. Place the fabric under the UV light source and follow the same steps as you would for outdoor sun printing, adjusting the exposure time as needed. Indoor sun printing offers the convenience of being able to work at any time, regardless of weather conditions.

Developing and Fixing the Print

Rinsing the Fabric

After the fabric has been exposed to sunlight, it is time to develop the print. Start by rinsing the fabric under cool running water to remove any excess paint and the light-sensitive chemicals. Gently rub the fabric with your hands to ensure that all the unexposed chemicals are washed away. It is important to rinse the fabric thoroughly to prevent any residual chemicals from affecting the final print.

Removing Excess Paint

Once the fabric has been rinsed, carefully remove any excess paint that may have been left on the fabric. You can do this by gently rubbing the fabric with a sponge or soft brush. Take care not to scrub too vigorously, as this may damage the print. The goal is to remove any excess paint while preserving the design and colors of the print.

Fixing the Print

To ensure that your sun print is permanent and washable, it is necessary to fix the design. Mix a fixative solution according to the manufacturer’s instructions. This solution usually consists of a mixture of water and a fixative agent, such as hydrogen peroxide or a citric acid solution. Submerge the rinsed fabric in the fixative solution for the recommended amount of time. This process helps to stabilize the print and prevent it from fading or washing out.

Drying and Pressing

Once the fabric has been fixed, gently squeeze out any excess fixative solution and rinse the fabric under running water again to remove any remaining traces of the solution. After rinsing, carefully blot the fabric with a clean towel to remove excess water. Lay the fabric flat to dry, away from direct sunlight. Once the fabric is completely dry, you can optionally press it with an iron on a low heat setting to flatten any wrinkles and enhance the appearance of the print.

Adding Finishing Touches

Embellishments and Embroidery

To take your sun-printed fabric to the next level, consider adding embellishments or embroidery. You can sew beads, sequins, or small fabric pieces onto the print to add texture and visual interest. Embroidery can also be used to enhance the design or add intricate details. Experiment with different techniques and materials to create unique and personalized touches to your sun prints.

Fabric Manipulation Techniques

Fabric manipulation techniques, such as pleating, folding, or gathering, can transform your sun-printed fabric into three-dimensional works of art. These techniques can add depth, volume, and movement to the fabric.
