Thank you for responding to my request for information on Oil Printing,I
have already found your suggestions to be very useful.
With regard to your penultimate point:- addition of chrome alum. I have
not come across this, in this context before. Does it's addition make
the areas of untanned gelatine less fragile when wet? One problem that I
have encountered is that these areas are easily damaged by the brush.
Once again many thanks for your help, it is easy to go up a blind alley
when one works on these alternative processes in isolation.
Alex.
