电影染印法工艺对水的质量要求甚严。水温、pH值及水硬度都对浮雕片和空白片具有很大影响。我们对浮雕片清洗水,空白片水洗水硬度对浮雕片下色及空白片明胶性质的影响进行了初步试验。1.水硬度对浮雕片下色的影响我们将浮雕片光楔转移染料后,用不同硬度的水清洗。再与空白片进行染料下色转移,测量接收染料空白片密度,结果见表1。 Film dying process on the quality of water is very strict. Water temperature, pH and water hardness have a significant impact on embossing and blanking. We conducted a preliminary test on the effect of the washing water of the embossed tablets and the water hardness of the blank tablets on the color of the embossed tablets and the gelatin properties of the blank tablets. 1. The effect of water hardness on the subdued color of the embossed film After we transferred the dye to the embossed film wedge, we washed it with different hardness water. And then with the blank piece of dye color transfer, measuring the receiving dye blank film density, the results shown in Table 1.
