I used this process about 12 months ago using saturated potassium bichromate &
gum based glue. It worked though not very consistantly. Unfotunately I did not
follow this up until now when it doesn't work at all! Is this because my
bichromate solution is old? If any one who has experience of using this
process could give help or advice on the best and most consistant methods of
gum bichromate printing it would be most appreciated
thanks, Anthony
