Patent ID: 7997196

Claim:
A printing press comprising: a press bed assembly, comprising: an upper support assembly, said upper support assembly having a lower support surface; and a lower support assembly, said lower support assembly having an upper support surface, at least a portion of the upper support surface being substantially parallel to the lower support surface; and a print head assembly, comprising: a print head frame; a print roller, said print roller rotationally secured by the print head frame at a first position; a first roller, said first roller rotationally secured by the print head frame at a second position, said second position on the print frame being horizontally offset from the first position on the print frame in a first horizontal direction by a first horizontal distance and said first roller being adapted for contacting and rotationally traversing the lower support surface of the upper support assembly; and a torque arm, said torque arm having a first end secured to the print head frame and a handle end distally situated from the print head frame and said handle end being horizontally offset from the second position on the print frame in the first horizontal direction by a second horizontal distance, said torque arm being adapted for generating a first downward force on the upper support surface of the lower support assembly from the print roller by receiving a second downward force at said handle end, wherein a first magnitude of the first downward force is greater than a second magnitude of the second downward force and, the first magnitude is proportional to the second magnitude based on a difference between the second horizontal distance and the first horizontal distance.
