AU - 1014 Print Surface Roughness / Smoothness Tester
This equipment measures the roughness/smoothness as per the condition apply in the printing press nip at the moment of printing, by clamping the sample between a precise measuring head and a specially backing assembly with variable clamping pressure. Ideally suitable for writing, printing/coated paper and board. The micrometer values measure directly on calibrated Variable Area Flow Meters (Rotameters).
Measuring Range:
0.9 6.0 (Micrometers)
Spesification
SPECIFICATIONS
Roughness / Smoothness
The roughness or smoothness of a sheet of paper or board is a function of the rate at which air will pass between a specified flat land and sheet of the paper or board when tested under specified conditions. The property is termed roughness if increasing numerical value indicate increasing roughness. It is named smoothness of increasing numerical values indicate increasing smoothness.
Print Surface Roughness
Air at regulated pressure is passed between a thin metal metering (51 micron wide) and the test paper surface, whereby the resistance of air-flow is measured. The roughness of the sample is calculated as micrometers on calibrated air flow meter as the cube root mean cube gap.
