Colormetric Evaluation on the Wet End, 1992 Papermakers Conference Proceedings

There has been a need within the paper industry for years to evaluate the color of the dyed slurry prior to entering the head box. This evaluation will enable the production crew to make a judgement while the slurry is being processed, instead of altering it after it is rolled. Technology is at a stage where this type of evaluation is possible with the aide of computers, sample presentation devices and spectrophotometers. A predetermined amount of dyed slurry is poured into the Slurry Flattener (a sample presentation device for spectrophotometers). Within a matter of a few minutes the slurry is flattened and its color is measured and compared against the last batch.

This new technology will improve the efficiency of the entire paper-making process.
