According to various embodiments, the present teachings relate to an alignment device, method, and system for aligning an upper platen of a paperboard press with a lower platen of a paperboard press. The alignment device can comprise a latching collar adapted to be mounted on a lower platen. The latching collar can comprise a central hole and can be adapted to be mounted on or affixed to the lower platen. The latching collar can comprise a locking area. The alignment device can further comprise a plunger unit. The plunger unit can comprise a housing, a securing device attached to the housing, and a plunger configured for reciprocal motion through the housing. The securing device can be adapted to removably secure the housing to a top surface of an upper platen of a paperboard press. The alignment device can further comprise a biasing device for normally biasing the plunger in a retracted position with respect to the housing yet permitting the plunger to be pushed partially through the housing to attain an extended position.
