How to Solve Uneven Gloss in Coated Paper

In the production process of coated paper, uneven gloss not only affects the visual appearance of the paper surface but also directly reduces its perceived quality. Through extensive on-site diagnostics and technical upgrades, Leizhan Company has developed a set of effective solutions for uneven gloss in coated paper, helping companies improve paper surface consistency from the root cause.

Systematic Improvement Plan for Coated Paper

Regularly calibrate the doctor blade angle and back roll runout accuracy to avoid periodic gloss streaks.
Provide an automatic coating-head unclogging and abrasion-detection system to reduce blind spots in manual inspection.
Recommend the optimal range of coating amounts based on machine speed and quantity to avoid overcoating or undercoating.
Temperature and airflow are controlled in each drying part to ensure slow, uniform film formation.
Gloss data is integrated into a DCS or QCS system to reverse-adjust parameters such as coating amount and calendering pressure, achieving closed-loop control.
