Controlled drying technique introduced into printmaking and hand papermaking workshops to shorten drying time and ensure planarity of paper. To do this a material that features open air ducts that promote air exchange is integrated into the structure of the drying stack. Drying is carried out in stacks of corrugated cardboard and other paperboard materials under slight pressure. The stack is equipped with a blower that provides a continuous air-stream through the open channels. The water is removed by continuous evaporation through the moisture-absorbing board until equilibrium with the ambient air is reached.
