If you search for cyanotype online, you will quickly notice that it is often spelled incorrectly.
Common variations include sianotype, cianotype, cyanotipe, or even ciano print. In almost every case, people mean the same thing: the distinctive blue-and-white prints created using light, chemistry and paper or fabric.

In this article, you’ll learn:

• what a cyanotype actually is

• why it is so often misspelled

• whether sianotype or cianotype are different techniques (spoiler: they are not)

• and how cyanoprints are made

What is a cyanotype?

A cyanotype is a historic photographic printing process developed in the 19th century. Paper or fabric is coated with a light-sensitive solution and then exposed to UV light, usually sunlight or a UV lamp. After washing with water, the image appears in a deep blue color known as Prussian blue.

Cyanotypes are commonly used for:

• botanical prints

• camera-less photography

• fine art and illustration

• textile printing

• workshops and education

The process is valued for its simplicity, durability and unmistakable blue aesthetic.

Cyanotype, sianotype or cianotype – which spelling is correct?

The correct spelling is: cyanotype.

However, many people search for:

• sianotype

• cianotype

• cyanotipe

• cyanotiep

• ciano print

• siano print

• cyanoprint

Why does this happen?

There are several reasons:

1. Pronunciation
   “Cyanotype” is often pronounced like “siano-type.”

2. Language influence
   In many languages, “ci” and “si” produce a similar sound.

3. Unfamiliar term
   Because cyanotype is not a common word, people often guess the spelling.

Important to know: all these terms refer to the same process.

Is a cyanoprint different from a cyanotype?

No.
A cyanoprint is simply another way of describing a cyanotype print.

People often search for:

• cyanoprint

• cianoprint

• siano print

In nearly all cases, they mean:

a blue print created using the cyanotype process

Common misspellings and what they really mean

If you use one of these terms, you’re looking for the right technique — just with a slightly incorrect spelling 😉

How do you make a cyanotype (or “sianotype” 😉)?

The basic process is straightforward:

1. Two chemicals are mixed into a light-sensitive solution

2. The solution is applied to paper or fabric

3. The coated surface dries in the dark

4. Objects or a negative are placed on top

5. The material is exposed to sunlight or UV light

6. The print is washed in water

The result is a blue-and-white image that deepens in color as it dries.

Why is cyanotype so popular?

Cyanotype remains popular because it:

• is easy to learn

• requires minimal equipment

• is safe when used correctly

• produces unique, organic results

• encourages experimentation

It fits perfectly within:

• analog photography

• slow art practices

• handmade processes

• creative exploration
