A press for documents or patterns printed with powder ink on a plastic or paper substrate has a controller for applying pressure and heat to one or more printed substrates or to a stack of plural printed substrates. The controller includes heating plates that cause the applied pressure and heat to be such that the pressure and temperature of the substrate(s) or stack has at least one specified pressure and temperature, in accordance with specified cycles. During the cycles, the controller varies the applied temperature and pressure for a specified duration. The stack includes at least one plate for separating the printed substrate(s) while the heat and pressure are applied. The heating and separating plates include finished surfaces for providing a finish to the printed document. A protective film is located between the finished surfaces and printed faces of the substrates while the pressure and heat are being applied.
