Inserting/extracting the board into/from the double sided "sandwich" is
where 90% of wear and tear occurs IMO. Epson dye ink on Epson
transparencies handles this best IMO. I wouldn't even think of using
Ultrachrome ink double sided artwork more than once unless there is a
clear overcoat. Single sided shouldn't be a problem with any reasonable
combo.
