From what I am reading of this thread, I can only conclude that there are
many people out there who are using photopolymer on a daily basis. This
leads to the common practice of developing a procedure which works. The
problem with this practice is that things change which you are not aware of.
I do not work much with film today but when I did the slightest change in
any of the steps could cause major changes in the outcome. Film, developer,
water, as well as environment can have a major impact on the total process.
I would suggest that even though you are getting your negs from the same
service, it is highly likely that they have changed suppliers or their
supplier may have changed their supplier. All of the other things involved
should be considered one at a time.
When a procedure works then stops working it is sometimes difficult to
remember how the procedure was developed. It is just done by habit and you
don't remember why some of the steps are important or how you came up with
I am just suggesting that the procedure be revisited and considered step by
step and make no assumptions. Only make one change at a time to eliminate
I know film processing is an art which has been mechanized to the point that
no one needs to make note today.
I hope this is a help in finding the cause of the change.
