We evaluated the effect of colored and uncolored recycling whitewater on paper color using a semiautomatic handsheet former. The dynamics of the machine were investigated by using dyes and measuring the color changes of the hand-sheets. For white paper made with colored whitewater, there was an exponential relationship between color values and the number of handsheets produced. Change in handsheet color was related to change of dye concentration in the whitewater. This relationship can be used to predict changes in color and dye concentration. A point of interest was the large number of handsheets required for the system to reach steady state. Test results were used to compare the behavior of this sys-tem to that of a paper machine whitewater recycling system.
