Hi,
Haven't heard of developer soaking, but a long time ago I tried soaking
developing-out paper in a weak (0.5%) silver nitrate solution before
printing out. The reason for this is that a printing-out emulsion requires
an excess of silver over salt (i.e. some silver nitrate left over after all
the salts have been used up in making silver chloride, silver citrate, or
whatever), whereas developing-out emulsions have an excess of salt over
silver.
As I recall, it did not make a fantastic difference, but it did make a
difference.
Liam
