Re: Newer emulsions on lith paper.

["Tim Rudman" <tim.rudman@xxxxxxxxxx>]

At the moment they are still working well. Minor changes have not too much
affected their response. The writing is on the wall however, they have an
ultimatum to eliminate the cadmium . Replacement prototypes are
disappointing. At present they are building up stocks to last as long as
possible. I am using the larest batches with no problem.
The affected emulsion is that used in Kentona, Art Classic and Tapestry
papers (US equivalents are listed in the book) which has a unique response
to selenium after lith. Other 'lithable' papers are not affected.

(I'm not 100% sure which have changed) have caused any new or undesired lith
outcomes with their lith printing?
