I understand that he invented processes for multi colouring plates both by etching at different levels and using different thicknesses of ink.
“He invented the Hayter Technique for producing three colour engravings in a single pressing from one copper plate which is given three levels. The ink must be of different viscosity being thinned down with linseed oil. The process works on a similar process to that of the lithographic print. The thinner ink repels the thicker ones.”
Given that it is very difficult to produce multi-coloured prints it would be very interesting to experiment with these processes but it would be easier to do so in one of the Colour Viscosity printmaking workshops which it seems are taking place today. Hayter`s work in itself is not at all my style and was apparently an outstanding graphic artist although this example seems to be quite abstract to me.
I realise that his work is of historical and technical importance, but I would only be interested in his technique and I would not have found out about it if I had not been recommended to look him up.
I would not be able to understand the exact process unless first given a demonstration and had experimental supervision as I do not have the time and confidence to experiment with this on my own.
My own experimentation with two different coloured plates was not entirely successful and I was not satisfied with the results. This is probably because I was trying to set line etching against pattern. The patterned etching had to be printed much paler in colour than the line and subsequently any possibility of vibrant interaction of colours was cancelled out.
Color Viscosity printmaking workshop From 9 to July 13, 2012 Given by Teresa Gomez Martorell
CONTENT MATTER There are several ways of working in color printmaking. Created at the Atelier 17 by Stanley William Hayter, in the Hayter technique (or color viscosity), the different colors are printed at the same time by working the ink viscosity, the etching and with hard or soft rollers and brayers. This workshop will be focused on the possibilities of this technique with some guidelines by working plates with stencils, rollers, ink viscosity and degradees. At the same time, plates will be deeply etched to work with hard and soft rollers. The most important thing for the participating students is to learn the concept underlying this technique and how to integrate to their body of work.
