Beginner’s guide · Make & create

Print with sunlight
and careful timing.

Cyanotype uses iron-salt chemistry and ultraviolet light to make Prussian-blue contact prints. Pre-coated paper is the simplest first route; mixing sensitiser is the controlled upgrade.

Quick answer

Begin with pre-coated paper and flat objects

Use ready-sensitised cyanotype paper, opaque leaves or cut shapes and a clear acrylic sheet. Assemble away from strong UV, expose according to the paper and conditions, then wash fully in plain water.

The quick answer
  1. 01

    Keep sensitised paper in its light-safe packaging until every object and clip is ready. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  2. 02

    Use flat opaque specimens because gaps create soft edges during contact exposure. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  3. 03

    Make a small timed test strip when sunlight or season differs from the instructions. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  4. 04

    Wash until unreacted chemistry is removed and allow the blue to deepen as the print oxidises. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  5. 05

    Treat mixed sensitiser as photographic chemistry and follow its safety sheet, storage and disposal instructions. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

02

What to expect

Sunlight is the variable you cannot set with a dial

Cyanotype is simple in materials but exposure changes with cloud, season, latitude, object density and the exact sensitised surface.

01

Exposure

A time that works at noon in summer may underexpose on a cloudy winter afternoon. The colour change and a test strip are better guides than memory. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

02

Contact

Sharp outlines require the object, negative and coated surface to touch closely across the whole image. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

03

Washing

An under-washed print can stain or change unpredictably. Fresh water and the stated rinse time complete the process. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

04

Oxidation

The final deep blue may take time to appear. Judge a dry oxidised print rather than the first pale image from the rinse. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

03

Core method

Separate setup light from exposure light

Plan in ordinary indoor light

Arrange dry objects and clips before opening the packet, avoiding direct sun or strong UV sources. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Make firm contact

Place the object on the coated side, cover with clean acrylic or glass and secure it without allowing the stack to slide. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Expose and record

Follow the kit’s starting time, note sky conditions and make a test when precision matters. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Wash and dry

Rinse in clean water for the directed time, handle wet paper gently and dry flat before judging density. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Products with a clear job in the setup

Pre-coated paper gets to the first print safely and quickly. A larger format and measured two-part chemistry are genuine next steps, not required purchases.

First project

Make a four-exposure test with one leaf

A small exposure ladder produces useful local timing and still leaves room for a composed final print.

  1. 01

    Prepare four sheets

    Label the backs in indoor light and choose one flat opaque leaf or cut-paper silhouette for consistent testing. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  2. 02

    Secure contact

    Place the object and acrylic on the first sheet, clip without bowing the stack and take it outside covered. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  3. 03

    Vary only time

    Expose the four sheets for planned increasing intervals while keeping position and object unchanged. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  4. 04

    Wash consistently

    Rinse each sheet for the same directed time in fresh water and lay it flat away from direct sun. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  5. 05

    Choose and print

    After drying and oxidation, select the best exposure and use it for a more considered multi-object composition. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

06

What can wait

What can wait until the first result

Mixed chemistry, digital negatives and toning add variables after exposure and washing should already be predictable.

  • 01

    Home-coated paper

    Coating introduces mixing, brush marks, drying and dark storage. Pre-coated sheets teach the image-making cycle first. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  • 02

    UV exposure unit

    Sunlight is free and sufficient for early contact prints; a controlled lamp matters when repeatability becomes the limit. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  • 03

    Toning recipes

    Tea, tannin and other toners change colour and permanence. Establish a well-washed standard blue print before altering it. For cyanotype printing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Safety & care

Use UV and chemistry deliberately

Pre-coated paper is approachable, but stronger UV sources and sensitiser require real safety controls.

  • Wear gloves and eye protection when mixing or coating chemistry and follow the product safety data. Follow the current instructions supplied with the exact material or tool.
  • Do not stare into UV lamps or expose skin; use only a properly enclosed source designed for the process. Follow the current instructions supplied with the exact material or tool.
  • Keep chemicals, trays and brushes labelled and permanently separate from food preparation. Follow the current instructions supplied with the exact material or tool.
  • Identify plants safely, avoid protected specimens and wash hands after handling outdoor material. Follow the current instructions supplied with the exact material or tool.
09

Outside help

When outside help earns its place

Pre-coated sun paper needs only a clear demonstration. A photography or printmaking workshop is useful before coating fabric, making digital negatives or installing a UV unit.
