PURPOSE: A printing device for controlling printing pressure is provided to enhance printing quality since a target suffers uniform surface pressure by an air bearing. CONSTITUTION: A printing device for controlling printing pressure comprises a micro gravure roll(6), a guide roll(8), a doctor blade, a target(4), an ink pen, an ink viscosity adjusting unit, and a monitor(40). The micro gravure roll rotates on the contrary to the moving direction of the target. The guide roll moves up and down before and after the micro gravure roll to adjust a covering angle. The doctor blade prevents ink from becoming excessively coated on the micro gravure roll. The target moves by the rolls and is printed by the micro gravure roll. The ink pen stores ink for printing the target. The ink viscosity adjusting unit controls the ink viscosity of the ink pen. |
