The work presented here is the result of a collaboration between the National Portrait Gallery and Disruptive Print, then part of the Centre for Print Research at the University of the West of England. The National Portrait Gallery approached us when they were looking for someone who could help them to print colour images taken by Madame Yevonde in the 30s of the last century. Madame Yevonde was the most famous user of the VIVEX process, the photomechanical reproduction process for colour photographs before the second world war in the UK. The VIVEX process was a commercial method and therefore only ill documented. What we know is that the images were taken through red, green, and blue filters on black and white film and then printed by layering pigmented gelatine layers in cyan, magenta, and yellow in top of each other, but how exactly is lost. We will discuss the registration of the three negatives and possible printing methods.

Well, I almost made it. I got to the point where it said they had been told that I was signing in but they must have been busy with the talk and didn't notice.
I'm one of the last practitioners of the three-colour carbon process. I wrote several books on pigment processes including the HISTORY AND PRACTICE OF CARBON PROCESSES (1982). I have a few Vivex prints in my collection. One of them can be viewed here:

My ENCYCLOPEDIA OF PRINTING, PHOTOGRAPHIC AND PHOTOMECHANICAL PROCESSES has a considerable amount of information on Vivex. The old version of this book is available online:

It seems that you need to create an account, etc., before attending the talk, so don't leave it too late before the talk!
