Packaging plant printing surface roughness treatment
Packaging plant paper and cardboard roughness and smoothness of the same, and paper printability is closely related to affect the ink handling process on the paper surface, thus affecting the visual appearance of the printed appearance. Roughness is generally determined using the air leakage method, which is subdivided into the Bengtsson method and the printing appearance method. Bengtsson method is under the specified experimental conditions and operating pressure, the measurement of the air flow rate between the ring plane or...
