FLEXO Magazine : December 2012
the readings tend to be somewhat subjective. Conversely, within the other methods, the differences are insignificant, with the electronic methods showing the least dependency on operator skill. The 3DQC and Anicam produce precise results with enough accuracy that they could be used for quality control (QC) purposes. The Microfax also shows sufficient accuracy but is a transfer method, which must be read by one of the electronic methods to maintain that exactness. There is a difference between the nominal volumes measured by these systems, which could be a function of calibration or cell ge- ometry combined with the mode of measurement. The results of the Liquid Volume method have the potential for QC accuracy provided sufficient repeat measurements are taken to make a reliable estimate of cell volume. The next project will examine the same exercise on open cell engravings gauge R & R study. n About the Author: Dan Reilly is application specialist, Flint Group, Packaging and Narrow Web.
