 Modern papermaking techniques use a dandy roll to create the laid pattern during the early stages of manufacture, similar to the way a watermark is added to handmade papers.While in the wet state, the paper stock (a dilute dispersion of the cellulose fibers in water) is drained on a wire mesh to de-water the stock.During this process, a dandy roll with a laid mesh pattern is pressed into the wet stock, displacing the cellulose fiber.
