REVISED CALIBRATION CURVE FOR DETERMINATION OF STAIN RESISTANCE OF VINYL MATERIALS

摘要

In previous work calibration curves were presented for use in determining stain resistance of vinyl materials using a color difference meter. These curves were obtained using two tiles for standards. A blue tile was used with the stained samples and a white tile for the unstained samples.nTo simplify this procedure we decided to calibrate the color difference meter using one tile which would result in a single calibration curve. This report discussed this investigation.
