The main function of the calibrated paper is to offset the various effects of the thickness deviation of the printing device and the rubber blanket on the printing pressure, and ensure good contact of the embossing surface. Therefore, it is a compensation link for various errors of the printing device. The underpacking paper can absorb the vibration impact generated in the embossing contact area of the printing device under the action of dynamic load, and can also change the compression deformation to adjust the printing pressure. The thickness of the base paper directly affects the printing pressure. Therefore, the thickness of the base paper is related to the state of the printing press, and once it is determined, it cannot be changed at will.
It serves several purposes:
Provides cushioning: Placed beneath the rubber blanket on the printing press, underpacking paper helps absorb pressure during the printing process. This protects the blanket from damage and ensures consistent print quality.
Maintains print pressure: Underpacking paper comes in various calibrated thicknesses. Printers can adjust the thickness to achieve the optimal pressure for the specific printing job. This ensures even ink transfer and prevents issues like light printing or ink smudging.
Extends blanket life: By absorbing impact and maintaining consistent pressure, underpacking paper helps extend the lifespan of the expensive rubber blanket.
Underpacking paper is typically made from compressed cardboard or synthetic materials. It's important to note that underpacking paper is different from regular packing paper used for shipping.
