A CARBON TRANSFER PRINT, also known as a Carbon pigment print, is a unique handmade work of art. It is a pigment and gelatine based photographic process, renowned for its remarkable beauty and archival stability because of the use of pigments over dyes. It has rich shadows, wide tonal range, sharp definition, richness of colour rendition and is considered to be the finest of all the photographic processes. A 19th century technique that was first invented in 1855, it is highly sought after by collectors. Though only a handful of artists worldwide practice it professionally. It is currently experiencing a revival with artists and photographers seeking a high-quality analogue alternative to digital production.
The underlying principal in this process is that once the light reactive chemical* has been applied to the gelatine, it will harden the substance once exposed to ultra violet light. When using a negative the hardened gelatine will be in proportion to the amount of light received. The image is then developed in hot water to melt away the soft unexposed parts of the image. This is a contact printing method and therefore the negative has to be the same size as the print.
The developed image can then be transferred to a temporary support before being transferred once again to a final support such as paper, glass or metal. In three colour carbon this could be a triple transfer procedure or as a double transfer. The prints produced are archivally very stable with a high gamut and long tonal range, which are rich and deep with a visible relief to them.
*Potassium Dichromate was the traditional sensitizer but highly toxic and regulations in the UK make it difficult to use without a licence. However a safer alternative is available which is less toxic and which is much more stable called Diazo or DAS.
All materials are produced from scratch. You will be instructed in the preparation of black and coloured carbon tissues and their sensitisation and will make enough to take some away with you, ready to use.
You will undertake 9 step and 21 step tonal and colour calibrations and learn to produce digital correction curves for image files, ready to send to an imagesetter service.
The temporary and final supports, will need to be prepared in advance of printing, however, you will learn to make all preparations during the workshop.
We will cover the history of Carbon Photography, production techniques and the safe handling of chemistry. You will be guided through the use of a pin registration system and a light exposure unit with a vacuum table. Once exposed the transfer of the exposed image to a temporary or final surface for development will be in hot water.
Due to the nature of the materials used, humidity, constituents and light can effect the materials in unpredictable ways. You will learn to identify problems and how to resolve them.
As we will be working with a package called CALIBRATION FOR ALTERNATIVE PHOTOGRAPHIC PROCESSES produced by The Wet Print, I would highly recommend purchasing this excellent and comprehensive online workshop in advance. The price is extremely reasonable at 59.95€. We will produce step tablets and calibration prints to measure with a spectrophotometer. I will guide you through the various steps.
Cost / price per person:
If 2 people attend together there would be a 40% discount for the second fee.
£250 per day for single and double transfer work over three days is £750, which includes all materials.
£280 per day for single and triple transfer work over 5 days is £1400, which includes all materials. More preparation is needed for the four colour process.
For the 5 day workshop, I suggest an extra day is factored in to the schedule to allow materials to dry. This would be an opportunity to have a day off.
If you wish to print in Black and white AND in colour we would need to work over 6 days. The charge would be £1680
There would be an additional charge as these are ordered from an external supplier and the price would depend on the size of the image to be printed. To achieve the finest result for your black and white image, three negatives are needed. For colour 8 negatives are needed.
All prices exclude VAT.

The technique was invented in 1855 by Alphonse Louis Poitevin (1818-1894), improved on and subsequently made available commercially by Joseph Wilson Swan (1823-1914) in 1864.
In the 19th century carbon printing was popular and was used extensively by museums and photographers as a means of making high quality permanent reproductions of silver gelatine photographs, paintings and drawings. A great many of Julia Margaret Cameron's photographs were produced as Carbon prints. Silver salts were still considered unstable at the time. It was a popular contact printing process but due to the fact that it could not be mechanised it fell out of commercial use in the 1930s and only a handful of people continued to practice the technique.
In recent years there has been a worldwide resurgence of interest in the process and with advances in production methods and the use of digital negatives. Carbon is once again becoming accessible for artists and photographers wishing to create high quality hand produced prints that look and feel unique. Carbon printing is to date the most archival printing method ever invented.
