Suppressing pitch aggregation and reducing stickiness! The frequency of doctor cleaning has decreased to one-third.
The decline in recovered paper quality has led to a rise in pitch-related defects, resulting in more damaged paper and an increase in quality complaints. To monitor the problem, we measured the amount of pitch by transferring white pigment onto the adhesive areas. By introducing “High Touch MP”, we successfully suppressed pitch aggregation and growth, significantly reducing pitch-related issues and improving overall paper quality. 【Case Summary】 Concern Declining recovered paper quality caused more pitch defects, leading to damaged paper and a rise in quality complaints.
