Further to yesterday's experiment I tested odorless sepia toner :
1) Overnight odorless toning of partially fixed RC print
2) 2,4, 8 and 10 minute odorless toning of fully washed and RC print
3) Overnight odorless toning of fully fixed and washed RC print
1) Overnight patch was slightly darker than 8 min patch on partially fixed
RC print
2) Even 'perfect' processed print showed some minor staining by odorless
toner after a few minutes toning.
3) Extended odorless toning of 'perfect' print showed slightly more staining
In all cases the toner left a slight stain. My guess is that the toner might
be actually staining the gelatine.
