Evaluation of the Gavarti Associates-Comprehensive Abrasion Tester
The GA-CAT (Gavarti Associates-Comprehensive Abrasion Tester) was put through sensitivity and repeatability studies to determine the variability associated with the machine. This was done to evaluate its ability to detect differences in quality within a batch of production run labels. The results showed that repeatability was poor so that quality variations in labels could not be assessed. The focus of the study therefore shifted to evaluating the causes of machine variability.
