(first of all sorry for my poor english...)
Yesterday I print some pictures with a new box of MGIV FB paper and got some unexpected results, the border of the image stains when tonned in selenium
here is an example:
(my scanner is a cheap one it looks much worse on the eye)
I always use the same process and the same FB paper and never get any kind of problem:
_ 2 minute in Ilford multigrade dev diluted at 1:9 (constant agitation)
_ 30 sec in stopper (constant agitation)
_ 1 minute in Ilford rapid fixer 1:4 (constant agitation)
_ 2 minutes in water
_ selenium toning (constant agitation)
_ washing for an hour
_ glazing 2 minutes in mirasol
also the toning appears to be much faster and some part of the pictures are white when others are nearly yellow... I try with a new batch of chemicals (all of them), same result!
What is going on? Do you experience this problem before?
thank you for your help!
A 2-minute wash after fixing sounds to me like too little washing after fixing. If there is residual fixer when you tone, you will get stains. I usually wash for min. 20 minutes after fixing and before selenium toning.
I suggest you have a look at this thread. It's full of good info pertaining to staining after selenium toning.
