Pulp-Delta-Color system for L ^* a ^* b ^* measurement of pulp slurry

Abstract

Color-difference meters are used to assure the quality of the end products. The new color-difference meter for process control called pulp-delta-color system is proposed in this paper.
Many troubles in paper color matching occur in the pulp dyeing process, so the stabilization of slurry color is a matter of great importance. This pulp-delta-color system also helps to save time and labor.
