NEW SIMPLIFIED SYSTEM OF CHARTS FOR RAPID COLOR DIFFERENCE CALCULATIONS
COLOR DIFFERENCE CALCULATIONS ARE TIME CONSUMING AND ERROR-PRONE TO THE EXTENT THAT THEIR USE HAS BEEN HINDERED IN ROUTINE PRODUCTION APPLICATION. A SET OF CALCULATING CHARTS HAS BEEN DEVISED TO GIVE COLOR DIFFERENCE FROM COLORIMETRY READINGS IN SECONDS RATHER THAN MINUTES. THE CHARTS HAVE BEEN TESTED IN THE LABORATORY AND IN PRODUCTION APPLICATIONS. IT IS NOW POSSIBLE FOR PRODUCTION OR LABORATORY PERSONNEL TO MAKE COLOR DIFFERENCE CALCULATIONS WITH A MINIMUM OF TIME-CONSUMING OPERATIONS. SUMMARIZING THESE OPERATIONS: (1) SUBTRACT 2 COLORIMETER RATIOS, (2) PLOT THE RESULTS OF THESE SUBTRACTIONS, (3) READ CHROMATICITY DIFFERENCE OFF CHART, (4) PLOT CHROMATICITY DIFFERENCES AGAINST Y COLORIMETER RATIO AND (5) READ OFF COLOR DIFFERENCE. COMPLETE SETS OF CHARTS ARE NOW AVAILABLE FOR USE WITH ALL COLORIMETERS.
