– ???????? – manufacturing defect where a piece of face veneer runs perpendicular to the board’s length
– ???????????? – orientation of successive veneer layers, placing them perpendicular to the adjacent layers of the plywood
– ??? – refers to how the veneer is made; either rotary cut or sliced
– ???????????? – failure of plywood panels, where the adhesive used to attach the plys fails, usually due to water
– ???? – the side of the plywood with the higher grade finish
– ????? – system by which the quality of plywood’s surfaces are identified
