Static marking is a hidden delayed defect unique to high-speed stacked paper, which is different from ordinary static adsorption and dust accumulation. In dry-season high-speed paper collection and stacking processes, instantaneous static charge accumulation between paper sheets produces invisible electrostatic traces. After sealed stacking and storage, these static traces gradually induce micro color difference, faint shadow marks and uneven ink absorption points on the paper surface. Static marking is extremely difficult to detect when leaving the factory, and only appears after printing or long-term storage, causing large-area pattern shadow defects and batch printing inconsistency. Ordinary antistatic agents only eliminate instantaneous static electricity but cannot eliminate residual static latent traces, resulting in recurring marking defects in dry seasons. Long-term static residue will also slowly age fiber surface components and affect paper long-term printing adaptability. Shandong Ludao Energy Technology Co., Ltd. launches targeted static marking elimination solutions. By realizing continuous uniform static dissipation and eliminating residual electrostatic latent traces, we completely avoid static-induced delayed surface marking defects. The solution stabilizes paper surface uniformity after stacking, eliminates seasonal printing shadow hazards, and ensures consistent batch printing quality in dry and low-humidity environments.
