Dryer Screen Marks on Sliced Veneer
Causes and cures for the "net-like" visual defect that sometimes appears on veneer. May 21, 2009
Some hardwood species like anigre develop net marks during drying. What are the causes and how can it be solved?
From John Van Brussel, forum technical advisor:
I think you are referring to dryer screen marks. These can be removed by washing the veneer with oxalic acid. They are caused by oxidation between the steel of the dryer screens and the veneer.
From contributor J:
I use nylon screening. Works well for me.
