The difference between a current dye rate and a retrieved nominal dye rate for a new web color is used in a dye rate change response (boosted to speed color change) to change the dye rate/web color. Historical production dye rate data is accumulated and combined with current dye rate data to determine new color targets or nominal dye rates for web colors to be produced. A retrieved nominal dye rate and a current dye rate are combined using a filter factor, alpha ,(0 </= alpha </= 1), defining the fraction of the historical dye rate to combine with the remaining fraction of the active dye rate to determine a new nominal dye rate stored for a given product color. The current dye rate is preferably taken near the beginning of a run; however, it can be taken at any point and can be an averaged accumulation of data. |
