| Résumé : |
Shade matching or tinting involves a time consuming process during paint manufacturing. In conventional approach, instrumental colour matching technique is used on dry paint film. Here, a novel technique has been used for prediction of desired colour from liquid paint sample directly instead of dried shade panels. In this technique, different mathematical concepts like matrices, determinants and three dimension Cartesian coordinate geometry have been employed to correlate a relation between shades of liquid paint and corresponding dried paint film and a simple empirical formula has been derived to predict the unknown shade. The liquid standard shade sample and nonstandard batch sample are taken in two identical transparent glass tubes, and with the help of three dimensional Cartesian coordinate geometry, a close relation of shade between liquid paint sample and dry painted panel has been established. This technique has also been used successfully for batch correction with respect to shade variation. Such unique colour matching technique has significant advantages over reduction of batch process time which has a direct impact on productivity and cost of fiNished paint. |
