Shipping stencil oil boards and oil board rolls are used with compatible stencil machines to create custom stencils for marking information on shipping containers and products. The machine punches out the message in the board or roll, the board or roll is then placed on the container or product, and ink is applied to the board or roll to paint the message onto the container or product. The boards and rolls are made from materials that resist ink bleedthrough, which helps ensure they create crisp, readable messages. Shipping stencil oil boards and oil board rolls can be used on flat or curved surfaces.
