The process involves the use of UV-light to make the image: so far so good
;-) The process can be used to vary greatly the colour of the final image,
depending on what chemicals are used at the start. It is not, so far as I
can understand, a full four-colour process, and the basis is either a
monochrome or two-colour image. It is possible to simply wash away areas of
the image (which sounds slightly gimmicky and not very permanent to me).
The process was/is, I think, produced by one company only (?which).
It may be that this process is not something that should be dealt with on
this list or taken seriously by artists such as those who write in its
virtual pages - but I am curious to find out exactly what is involved...
Apologies if this is not the right venue for this inquiry!
