The Machine Press is a machine in the game that allows you to create various quest items out of rolls. The press is located in Gearlock Factory, Steamport City in the small room diagonally to the left of the Sump Pump Checkpoint. You need a die from Wystan to be able to operate it.
The Machine Press is not currently used in everyday crafting. The only time the Machine Press is used is when its required for a quest.
